[Detailed explanation of the invention] [Industrial application field] This invention supplies hot water heated by exhaust heat from a stove or a small water heater into the inside of the pine, and uses the heat radiated from the surface of the pine to cool rooms, etc. (especially This relates to a heat dissipation mat that heats the floor surface of a room, etc.

[Prior art] Stoves are used to heat rooms, etc. in cold seasons and places such as winter, and
There is a floor heating system that performs floor heating by effectively utilizing the exhaust heat from the stove or a small water heater. By the way, as a heat radiation mat for radiating heat of hot water supplied through a pump etc. used in this system to the outside,
Conventionally, metal panels, sponge panels, and rubber panels have been used.

[Problems to be solved by the invention] However, the above-mentioned conventional heat dissipation mat using panels has pipes or tubes installed inside the mat to circulate hot water.
Its manufacture was relatively troublesome, and it was also heavy. In addition, because heat dissipation mats using any panel use pipes or tubes, there is a so-called dead space for warm water, which is a part where hot water circulates and where the tubes do not touch, making it difficult to maintain heat effectively. In addition, there was a problem that the heat dissipation efficiency was not good.

The present invention has been made in view of the above points, and aims to provide a heat dissipation mat that is lightweight and easy to manufacture, has a small hot water dead space, is highly heat retaining, and has high heat dissipation efficiency.

[Means for Solving the Problems] In order to achieve the above object, the heat dissipation mat according to the present invention includes a water-shielding sheet in which a large number of small protrusions 8 are formed by forming an uneven shape inside the mat. A water guiding sheet 3 having a water guiding sheet 3 is provided, and a flow path for hot water circulating on the outer peripheral surface is formed on the outer peripheral surface of each of the small protrusions 8 of the water guiding sheet 3, and a flow path for hot water is formed on the inner peripheral surface of each of the small protrusions 8. is characterized by the fact that it is filled with air.

[Function] Hot water sent from the exhaust heat of the stove or from a small water heater or the like via a pump or the like is supplied to the water guiding sheet through the supply water guiding nozzle. The hot water supplied to the water guide sheet passes through the outer circumferential surface of a plurality of small protrusions formed on the water guide sheet, circulates within the water guide sheet along the circulation path, and is sent to the pump side via the discharge water guide nozzle. Ru. Heat is stored and kept warm by the air on the inner peripheral surface of the small protrusions in the water guide sheet, and the heat of the hot water that is evenly diffused and circulated on the surface is evenly released upward to the outside through the surface protection sheet. Ru. Furthermore, the air enclosed within the small protrusions provides good cushioning and contact.

[First example] A first embodiment of the present invention will be described below.

FIG. 1 is a partially cutaway view of the heat dissipation mat of the present invention, and FIG. 2 is a partial sectional view of the heat dissipation mat of the first embodiment.

In the figure, 1 indicates a heat dissipation mat, and this heat dissipation mat 1 is used to guide waste heat from a stove, etc. (heating equipment), hot water W heated by a small water heater, etc., into and out of the heat dissipation mat 1 via a pump, etc. A water guiding nozzle 2 , a water guiding sheet 3 having a large number of small protrusions 8 (described later) formed on its surface, a surface protection sheet 4 fixedly laid on the upper surface of the water guiding sheet 3, and a back surface of the water guiding sheet 3. A heat insulating member 5 is provided through a protective sheet 11 to prevent the internal heat warmed by the hot water W from being released to the lower part.
and a protective cover 6 for protecting the bottom and outer peripheral edge.

Next, each component of the heat dissipation mat 1 constructed as described above will be explained in detail.

First, as shown in FIG. 1, the water guide nozzle 2 includes a supply water guide nozzle 2a for guiding hot water W sent from a pump, etc. (not shown) to the water guide sheet 3, and a supply water guide nozzle 2a for guiding the hot water W sent from the water guide sheet 3 to the pump, etc. side. It consists of a discharge water introduction nozzle 2b for sending out water. One end of these water guide nozzles 2, 2a, 2b penetrates the protective cover 6 to approximately the center of the water guide nozzles 2, 2a, 2b, and the end is between the surface protection sheet 4 and the water guide sheet 3. They are placed side by side in a state that they are nestled inside. In addition, the other end protruding from the protective cover 6 is connected to a tube T having an inner diameter approximately the same as the outer diameter of the water guide nozzles 2, 2a, and 2b, as shown by the two-dot chain line in the figure. ,
Hot water W is supplied and sent out from a pump (not shown) or the like, and the hot water W is circulated (in the direction shown by the arrow in FIG. 1) within the heat radiation mat 1.

Here, ring-shaped protrusions 2c are arranged at several locations at regular intervals on the nozzle opening portion connected to the tube T, so that the sealing performance with the tube T is improved and the tube T is removed. We are trying to prevent it. In addition, a bamboo shoot-shaped nozzle whose outer diameter changes stepwise and whose tip has a small diameter may be used.

Next, the water guiding sheet 3 is a top sheet 3 that forms cap-shaped small protrusions 8 containing air 7 inside.
It is constructed by polymerizing and welding two sheets of thermoplastic resin such as polyethylene, ie, a lower sheet 3b forming the base of the upper sheet 3a.

A plurality of small protrusions 8 are formed alternately and densely at regular intervals on the lower sheet 3b.
Then, while the hot water W is supplied into the water guide sheet 3, the air 7 within the plurality of cap-shaped small protrusions 8 is heated, increasing the heat retention effect of the hot water W within the heat dissipation mat 1. By the way, the water guide sheet 3 is formed of a member having sufficient pressure resistance against external forces, and the plurality of small protrusions 8 formed on the water guide sheet 3 resist such external forces. It is flexible and disperses force.

Next, the surface protection sheet 4 is made of, for example, polyethylene, and the water guide sheet 3
The water guide sheet 3 is fixedly laid on the upper surface of the water guide sheet 3 to protect it from external shocks, and to uniformly release the heat of the hot water W circulating inside the water guide sheet 3 upwardly to the outside.

In addition, as shown in FIG.
A cross yarn sheet 4b may be placed on the upper surface, a reinforcing nylon sheet 4c may be placed on the upper surface, and a reinforcing nylon cloth sheet 4d may be placed on the upper surface, and each of these may be laminated. Furthermore, this surface protection sheet 4 can also be used by polymerizing a thick laminate sheet or an aluminum vapor-deposited sheet.

In addition, the water guide sheet 3 located on the lower surface of the surface protection sheet 4 is replaced with the above-mentioned upper and lower sheets 3a,
In addition to the water guide sheet 3b having a double structure, another sheet 3c made of the same material is polymerized and welded onto the top sheet 3a on which small protrusions are formed, resulting in a triple structure. You can also do that.

Then, a protective sheet 11 which is located on the lower surface of the water guiding sheet 3 and is joined to the heat insulating member 5, which will be described later, is made by placing a nylon sheet 11b on an aluminum vapor-deposited cross yarn sheet 11a serving as a base, and further, on the upper surface of the protective sheet 11, a polyethylene sheet 11
The polymer 12 shown in FIG. 3b is formed by laminating each of the above-described surface protection sheet 4, water-conducting sheet 3, and protection sheet 11, respectively, to form a polymer 12 shown in FIG. 3b. You may also do this.

In this case, the surface protection sheet 4 has a four-layer structure, and the water-conducting sheet 3 and the protection sheet 11 have a three-layer structure, which increases the durability against external impact and improves the heat retention effect of the hot water W inside the water-conducting sheet 3. It has the following advantages.

Incidentally, a welding line 9 is formed between the surface of the water guiding sheet 3 and the surface protection sheet 4, which are shown by the dashed line in FIG. 1, by welding each of them. As a result, the heat dissipation mat 1 is
The hot water W supplied to the is guided to the discharge water guide nozzle 2.
A recirculation passage 10 is formed between the hot water discharged from the water guide sheet 3, and the hot water W is uniformly diffused and circulated through the water guide sheet 3.

Next, the heat insulating member 5 is disposed to be bonded to the back surface of the water guide sheet 3 via the protective sheet 11, and releases the heat of the hot water W circulating inside the water guide sheet 3 to the lower part of the water guide sheet 3. It is made of, for example, thick urethane or polyethylene packaging cushioning material that does not reduce the heat retention effect and heat dissipation efficiency of the hot water W inside.

Next, the protective cover 6 covers other parts (bottom, side edges) of the surface protection sheet 4 except for the surface, and protects it from external impact. Next, the operation of the heat dissipation mat having the above-described structure will be explained.

First, hot water W sent via a pump or the like from exhaust heat from a stove (not shown) or a small water heater is supplied into the water guiding sheet 3 through the supply water guiding nozzle 2a. The hot water W supplied into the water guiding sheet 3 passes through the circumferential surface 8a of the plurality of small protrusions 8 formed in the water guiding sheet 3, and circulates within the water guiding sheet 3 along the circulation passage 10 (as shown in FIG. 1). direction shown by the arrow). At this point, the air 7 within the plurality of small protrusions 8 formed on the water guide sheet 3 has been warmed by the hot water W circulating inside, so that the heat retention effect in the heat dissipation mat 1 is enhanced. The hot water W circulating within the water guide sheet 3 is sent to the pump side via the discharge water guide nozzle 2b. Furthermore, the heat of the hot water W that is kept warm in the water guide sheet 3 and is evenly diffused and circulated in the water guide sheet 3 is uniformly released upward through the surface protection sheet 4, thereby providing optimal heating. will be performed.
