Embodiment Construction

[0023] In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] In this article, terms such as "up, down, left, right" are established based on the positional relationship shown in the drawings, and the corresponding positional relationship may also change according to different drawings. Therefore, it is not possible to use It is understood to be an absolute limitation on the scope of protection; moreover, relational terms such as "first" and "second" etc. are only used to distinguish one element of the same name from another, and do not necessarily require or Any such actual relationship or order between these components is implied; "communication" means direct communication or indirect communication through other channels.

[0025] refer to Figure 1-Figure 6 , a heat exchanger, including a core 10, t...

Abstract

The heat exchanger comprises a core body, the core body comprises a first plate sheet and a second plate sheet, the core body is provided with a first fluid channel and a second fluid channel, the first fluid channel comprises a first inter-plate channel, the second fluid channel comprises a second inter-plate channel, the core body is provided with a first isolation part and a second isolation part, the first isolation part is located on the first plate sheet, and the second isolation part is located on the second plate sheet. The first isolation part is provided with a first welding part, a second welding part and a first main body part, the first welding part is provided with a first welding surface, and the first welding surface is welded and fixed with a second plate sheet adjacent to one side of the first plate sheet, so that the first isolation part divides the first inter-plate channel part into a first inter-sub-plate channel and a second inter-plate channel; the second welding part is provided with a second welding surface, and the second welding surface is welded and fixed with a second plate adjacent to the other side of the first plate, so that the second isolation part divides the second inter-plate channel part into a third inter-sub-plate channel and a fourth inter-sub-plate channel. Matching requirements of the isolation part can be reduced, installation is easy, and processing is convenient.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger. Background technique [0002] The plate heat exchanger has high heat exchange efficiency, the heat exchanger is relatively compact, and the weight is relatively light, and can be used in many industries such as refrigeration, chemical industry and water treatment. The basic principle of the plate heat exchanger is that the two heat exchange media conduct heat exchange through the heat exchange plates in the adjacent flow channels. With the increase in the application scenarios of plate heat exchangers, the performance requirements for plate heat exchangers are also increasing. In a heat exchanger with a U-shaped inter-plate channel, although the inter-plate channel is relatively long, the structure of the intermediate blocking portion of the plates adopts a nested stacking method, and the matching accuracy with the plates is required to be high.
