Description

Technical Field

[0001] The utility model relates to the technical field of cold plate connection structures, in particular to a connection structure of a novel inlet and outlet joint and a cold plate. Background Art

[0002] The existing cold plate heat exchanger is tightly fitted to the battery module through thermal conductive silicone. The heat of the battery is taken away by the flow of cooling medium inside the liquid cold plate cavity, and the battery is evenly heated. Usually one or two inlet and outlet joints are placed on a cold plate. However, for some battery packs, the inlet and outlet of the flow channel cannot be arranged in a reasonable position due to the distribution of battery cells and space limitations. As a result, the inlet and outlet joints are too large, difficult to process, and the processing cost is high. Utility Model Content

[0003] The purpose of the utility model is to provide a novel connection structure between an inlet and outlet joint and a cold plate, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of inlet and outlet joint connection structure and a cold plate connection structure, comprising a flat plate and a flow channel plate arranged at the lower part thereof, wherein the flat plate and one end of the flow channel plate are provided with a joint structure connected thereto, and the flat plate and the flow channel plate are welded and connected.

[0005] Further optimized, the joint structure includes a guide plate fixedly connected to the flat plate and the flow channel plate.

[0006] For further optimization, the end surface of the guide vane is provided with a medium inlet and a medium outlet connected thereto.

[0007] For further optimization, the guide plate is provided with a flow channel matching the flow channel plate.

[0008] For further optimization, one end and the middle of the guide plate are provided with threaded holes fixedly connected to the flat plate.

[0009] For further optimization, the other end of the medium inlet and the medium outlet away from the guide plate is provided with a rectangular joint fixedly connected thereto, and the medium outlet, the guide plate and the rectangular joint are an integrally formed structure.

[0010] Beneficial Effects

[0011] The new inlet and outlet joint connection structure and the cold plate provided by the utility model reduces the size of the water joint by adding a guide plate, guides the flow through the flow channel on the guide plate, connects the water joint and the cold plate, reduces the processing difficulty and manufacturing cost of the inlet and outlet joint NC, reduces the size of the inlet and outlet joint, and is also beneficial to reducing the heat absorbed by the furnace to ensure the welding quality.
