AI Technical Summary
The existing flow channel design of cold plate heat exchangers results in inefficient coolant movement, low heat exchange efficiency, and difficulty in breaking the gas film during the gas-liquid two-phase transition, which affects the heat exchange effect.
A novel flow channel plate is designed, which adopts a hexagonal island structure and turbulent flow channel. The regular arrangement of the flow channel forms turbulence, which enhances the flow of coolant in the channel, promotes the rupture of the air film, and improves the heat transfer effect.
The turbulent flow channels formed by the hexagonal island structure significantly improve the heat transfer effect between the coolant and the battery cell, thereby enhancing the heat exchange efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation cold plate flow channel technology, specifically a new type of flow channel plate that enhances heat exchange efficiency. Background Technology
[0002] The existing flow channel design of cold plate heat exchangers is a single straight flow channel design. In the current design, the coolant flows smoothly in the flow channel without vigorous movement, resulting in poor heat exchange efficiency. Moreover, in the flow channels of direct cold plates and direct cooling and direct heating plates, there is a switching between gas and liquid states. During the phase change process, the coolant forms a gas film. The gas film is not easy to break in the straight flow channel, which leads to a reduction in heat exchange effect and failure to exchange heat in a timely manner. Utility Model Content
[0003] The purpose of this invention is to provide a novel flow channel plate that enhances heat exchange efficiency, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel flow channel plate for enhancing heat exchange efficiency, characterized in that: it includes a flat plate, a flow channel plate connected to the other side of the flat plate, a medium interface plate at one end of the flat plate, and a medium inlet and a medium outlet respectively on one side of the medium interface plate.
[0005] In a further optimized configuration, the media interface board is provided with a connecting pipe, a first connecting block, and a second connecting block on the side away from the media inlet and media outlet.
[0006] In a further optimized configuration, both the first connecting block and the second connecting block are disposed throughout the flat plate.
[0007] In a further optimized configuration, the flat plate is welded to the flow channel plate.
[0008] In a further optimized version, the flow channel plate has multiple hexagonal island structures forming flow channels on the side near the flat plate.
[0009] In a further optimized design, all of the aforementioned hexagonal island structures are symmetrically arranged.
[0010] Beneficial effects
[0011] The novel flow channel plate for enhancing heat exchange efficiency provided by this utility model forms flow channels by regularly arranged hexagonal islands. The coolant flows violently within the flow channels, forming turbulence, which can effectively increase the heat transfer effect and facilitate the rupture of the air film, thereby better realizing the heat transfer between the coolant and the battery cell.
