Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating element, an intake air heating device, a heater and a heating device, and more particularly to a heating element having a structure using an exothermic reaction material, an intake heating device using the same, and a panel type heating device. The present invention relates to a heating device having a structure such as a heater or a hot plate.

[0002]

2. Description of the Related Art Known examples relating to the present invention include JP-A-2-193620 and JP-B-63-177857.
Publication No. 6-8457, Publication No. 6-845
No. 8 and Japanese Utility Model Publication No. 6-8459. These disclose, for example, quick heating lime as a reaction material and water as a material to be reacted, and the structure of a heating element used for heating a food or the like or heating a human body by using an exothermic reaction due to the contact thereof.

[0003]

However, in the above-mentioned known examples, the main object of the present application is an intake air heating device such as a heat engine, a panel heater having a substantially vertical surface, or a heating device such as a hot plate. The structure of the heating element using the reaction material is not disclosed.

An object of the present invention is to provide a structure in which intake air of a heat engine or the like is temporarily heated by a heating element using a reaction material,
To provide a structure when a heating element using a reaction material is used in a panel heater having a substantially vertical surface, or a structure where a heating element using a reaction material is used in a heating device such as a hot plate. It is a thing. Further, as the heating element, particularly in a structure having a substantially vertical surface, when the reaction target material is brought into contact with the reaction target material to generate heat, the action of gravity may not evenly spread, and the contact may be hindered. However, it provides a technique for solving such a difficulty.

[0005]

In order to achieve the above object, the present invention employs the following means. When starting a heat engine such as a diesel engine, it is difficult to start when the intake air temperature is low, and it is extremely difficult to electrically heat the intake air outdoors. Therefore, in the intake air heating device of the present invention, a member such as a bag containing a reaction material such as quick lime is provided around the intake port, and the reaction target material (for example, water) is brought into contact with the member at the time of startup to generate an exothermic reaction. Is causing

Further, in a simple panel type heater,
A member such as a bag containing a reaction material and a reaction material is placed inside an aluminum or polyethylene plate, and the reaction material and the reaction material are brought into contact with each other to generate heat when desired, and this heat is applied to the surface plate. Heat was transferred and heating was performed.

Further, in a simple hot plate type heating device, a bag containing a reaction material and a reaction material is put in a frame made of a plate of aluminum or the like, and they are brought into contact with each other when desired to generate an exothermic reaction. Then, the heat is transferred to the plate so that the cooked food can be heated.

In the present invention, the reaction material and the reaction target material are mainly used by putting them in a substantially vertical bag or container. In such a case, the bag containing the reaction target material is used. When the members such as the above are broken and brought into contact with the reaction material, the reaction material does not uniformly mix with the reaction material, resulting in uneven temperature. Therefore, a porous material having a capillary action is provided in the reaction material portion.

[0009]

In the intake air heating of the heat engine, when the reaction material and the reaction target material are brought into contact with each other to generate heat at a desired time, this heat is transferred to the intake air and the temperature of the intake air immediately rises even if the outside air is at a low temperature.
Booting starts immediately.

In a simple panel type heater, the heat generated by the contact between the reaction material and the reaction material is transmitted to the surface of the plate. From the surface of this plate, heat can be heated by transferring heat by radiation and convection. At this time, the shape of the bag containing the reaction material and the material to be reacted is firmly supported by the plate, so that the shape of the bag is not easily deformed.

In a simple hot plate type heating device, the heat generated by the contact between the reaction material and the reaction material is
It is transmitted to the cooked product through the surface of the plate and heats it. At this time, by placing the bag containing the reaction material and the bag containing the reaction target material in the limited space, the adhesion between the bag and the plate becomes good, and the heat transfer becomes extremely good. The above application example is extremely effective for rapid heating and heating when there is no power source in the field or the like.

Further, when the reaction material and the reaction material are brought into contact with each other in a substantially vertical bag or container, it is difficult for the reaction material to uniformly contact the reaction material, but the reaction material and the reaction material are difficult to uniformly contact with the reaction material. The reaction material is uniformly diffused, and thereafter, the reaction material receives the material to be reacted, uniformly generates heat, and has an effect of reducing temperature unevenness.

[0013]
