Abstract

(57) [Abstract] [Purpose] To obtain a heat exchanger capable of preventing the filler from squeezing out between the housing and the heat exchange element and absorbing variations in filler coating operation. [Structure] Ridge 8 of heat exchange element 5 in housing 9
The concave portion 15 is provided on the joint surface with. [Effect] By having the concave portion which is a space in which the filler can be filled, it is possible to absorb variations such as the protrusion of the filler from the housing during the coating operation, which is good in appearance.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat exchanger having a housing.

[0002]

[Prior Art]

 Conventionally, as this type of heat exchanger, as shown in FIG. 3, two heat exchange elements 1 each having a quadrangular prism shape are used, and two heat sinks 2 each having a triangular cross section are used. It is known that the ridges are sandwiched and the ridges of the housing 2 are filled with the filler 3 (see, for example, Japanese Utility Model Laid-Open No. 57-46267).

[0003]

[Problems to be solved by the device]

 In the conventional heat exchanger as described above, the filler 3 is filled between the housing 2 and the heat exchanging element 1 due to variations in the work of filling the housing 2 with the filler 3, especially when the filling amount is large. However, there is a problem that the filler 3 sticks out and is not aesthetically pleasing, and that the filler 3 adheres to other parts when the heat exchange element 1 is incorporated into other parts for use.

There is also a problem that the housing 1 is lifted by the filler 3.

The present invention has been made in order to solve the above problems, and there is no protrusion of the filler from between the housing and the heat exchange element, and there is no floating of the housing due to the filler. The purpose is to obtain a vessel.

[0006]

[Means for Solving the Problems]

 A heat exchanger according to the present invention comprises a plurality of partition plates stacked via a spacing plate, and a square column heat exchange element configured such that a primary air flow and a secondary air flow alternately flow between the layers. The ridges of the heat exchange element in the housing are provided by holding the respective ridges of the heat exchange element to prevent the primary air flow and the secondary air flow from being mixed with each other and having a housing composed of a plurality of parts. A concave portion is provided in the contact portion with the portion.

[0007]

[Action]

 In this invention, a plurality of partition plates are laminated via a spacing plate, and a square column heat exchange element configured such that a primary air stream and a secondary air stream flow alternately between the respective layers, and this heat exchange element. Each of the ridges is held to prevent the primary air flow and the secondary air flow from being mixed with each other, and a housing composed of a plurality of parts is provided, and the housing has a contact portion with the ridge of the heat exchange element. Since the concave portion is provided in the concave portion, the concave portion becomes a space filled with the filler.

【Example】

 1 and 2 are views showing an embodiment of the present invention, in which reference numeral 5 is a heat exchange element, which is made of, for example, paper, and a plurality of partition plates 6 are laminated with a spacing plate 7 interposed between them. The air flow and the secondary air flow are composed of a square column configured to flow alternately between the above layers. Reference numeral 8 is a ridge portion of this heat exchange element, 9 is a housing made of, for example, synthetic resin, and has a triangular cross-section as shown in FIG. 1 in which the ridge portion 8 of the heat exchange element 5 and the inner wall of the top portion 10 coincide with each other. A first engaging portion 11 and a second engaging portion 12, which are bent in opposite directions, are continuously provided at both ends. Reference numeral 13 denotes an engaging claw projectingly provided on the first locking portion 11, 14 denotes a hooking hole drilled in the second locking portion 12 so that the engaging claw is engaged. The housing 9 is formed by a cutout opening except for the top portion 10, the first locking portion 11 and the second locking portion 12. Reference numeral 15 denotes a recess, which is provided on the inner wall of the top portion 10 of the housing 9 and the inner walls of the first and second locking portions 11 and 12, and accordingly, this portion is thin. Reference numeral 16 is a filler, which is composed of, for example, a highly viscous mucus.

In the heat exchanger configured as described above, after the filler 16 is applied to each recess 15 of the housing 9, heat is applied to the two housings 9 from above and below as shown in FIG. The heat exchange element 5 is mounted so as to sandwich the exchange element 5, and the first locking portion and the second locking portion 12 are engaged with each other by fitting the engaging claw 13 into the hooking hole 14. This allows the heat exchange element 5 and the housing 9 to be joined together without the filler 16 protruding from the housing 9.

[0010]

[Effect of the device]

 As described above, the present invention has a square column heat exchange element in which a plurality of partition plates are laminated via a spacing plate and the primary air flow and the secondary air flow are alternately flowed between the layers. The ridges of the heat exchange element in the housing are provided by holding the respective ridges of the heat exchange element to prevent the primary air flow and the secondary air flow from being mixed with each other and having a housing composed of a plurality of parts. Since the concave portion is provided at the contact portion with the housing, the filler is absorbed by the concave portion when the filler is applied to the housing, and the protrusion of the filler and the floating of the housing are prevented when the heat exchanger element is assembled.
