no. 1 approach
[0040] A first embodiment will be described with reference to the drawings. The heat exchanger in this embodiment is used as a water-cooled intercooler, and cools intake air by exchanging heat between supercharged gas pressurized by a supercharger and having a high temperature and cooling water.
[0041] Such as Figure 1 ~ Figure 4 As shown, the heat exchanger 1 includes a pipe 100 , a core 200 , a caulking plate 300 , and a tank 400 .
[0042] The duct 100 is a cylindrical member through which pressurized gas as a first fluid flows. Such as image 3 As shown, the duct 100 is composed of a first duct plate 110 and a second duct plate 120 in which a thin metal plate such as aluminum is punched into a predetermined shape and combined into a cylindrical shape.
[0043] The duct 100 is configured to introduce pressurized gas from an inflow port and discharge the pressurized gas from an outflow port. Therefore, the pressurized gas flows from the inflow port of the duct 100 int...

[0078] In this embodiment, differences from the first embodiment will be described. Such as Figure 7 As shown, the core 200 has a fixing portion 240 . The fixing part 240 is another member different from the cooling plate 210 and the partition plate 230 .
[0079] The fixing portion 240 is configured, for example, as a plate-shaped member. In addition, the fixing part 240 is provided in all the pairs which consist of the cooling plate 210 and the partition plate 230. As shown in FIG. In this way, the end portion 216 of the cooling plate 210 may not be provided with the claw portion 215 , but the end portion 216 of the cooling plate 210 and the wall portion 232 of the partition plate 230 may be integrated with the fixing portion 240 .
[0080] In addition, in this embodiment, the fixing part 240 corresponds to an "integrated part".
no. 3 approach
[0082] In this embodiment, differences from the first and second embodiments will be described. Such as Figure 8 As shown, the fixing portion 240 is disposed on at least a part of all pairs formed by the cooling plate 210 and the partition plate 230 . Therefore, each cooling plate 210 is locally restricted. Therefore, the rigidity of the cooling plate 210 can be locally improved.
[0083] For example, if Figure 8 As shown, it is also possible to adopt a structure in which the fixing portion 240 is integrated in the lowermost cooling plate 210 where excessive thermal strain occurs, and the fixing portion 240 is not provided in the upper layer of the cooling plate 210 .

Abstract
Provided is a heat exchanger that is capable of reducing thermal distortion applied on a cup part. This heat exchanger is provided with: a duct (100) that has an inlet and an outlet; a core part (200); and a caulking plate (300). The core part has: a plurality of cooling plates (210) to which a first plate part (211) and a second plate part (212) are provided in a laminated manner; and a pluralityof spacer plates (230). The caulking plate is formed into a frame shape corresponding to the opening shapes of the inlet and the outlet, fixed to the inlet and the outlet, and caulks and fixes a tank(400) to a side opposite to the duct. The core part has integration sections (215, 230, 231, 233, 240) that integrate some of the spacer plates with some of the cooling plates opposite to the spacerplates.
Description
[0001] Cross-reference of related applications [0002] This application is based on Japanese Patent Application No. 2016-102446 filed on May 23, 2016, and the content of the description is incorporated in this application. technical field [0003] The present invention relates to a heat exchanger in which a core material is accommodated in a pipe. Background technique [0004] Conventionally, for example, Patent Document 1 proposes a heat exchanger having a structure in which a plurality of tubes are fixed to a pair of core plates. Specifically, each core plate is inserted and joined to both ends of each tube. Furthermore, the core plate is fixed to the opening of the cylindrical box through which the gas flows. Thereby, heat exchange is performed between the cooling fluid flowing through the tube and the gas flowing through the tank.
