Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a refrigerant direct cooling plate. Background Technology

[0002] With the rapid development of electric vehicles, battery cooling technology has received increasing attention. Battery heat dissipation methods include air cooling, liquid cooling, and direct refrigerant cooling. Direct cooling works similarly to air conditioning, primarily using the phase change of the refrigerant to transfer and dissipate heat. Because direct cooling systems eliminate the intermediate heat exchange process involving liquids, reducing thermal resistance, and possess excellent heat transfer performance and a compact system structure, they are gradually becoming the main development trend in battery thermal management systems. Currently, direct cooling systems are already being used in many new energy vehicles, and the role of direct cooling plates in battery heat exchange has attracted widespread attention.

[0003] Chinese utility model patent CN220830013U discloses a direct cooling plate for battery refrigerant, comprising a flat plate and a flow channel plate. The flat plate is disposed on the upper side of the flow channel plate, and a refrigerant flow cavity is formed inside the flow channel plate. Fins are placed inside the refrigerant flow cavity. Multiple mounting holes are formed on the upper surface of the flat plate, each corresponding to a first and a second water outlet. A water-cooling connector is fixedly mounted on the upper side of each mounting hole. The lower surface of the water-cooling connector is open. A first water outlet is fixedly mounted on one side of the upper surface of the water-cooling connector, and a second water outlet is fixedly mounted on the other side. Multiple grooves are sequentially formed on the sidewalls of the fins, and through slots are formed between multiple adjacent grooves on both sides. This design employs a complex fin structure to enhance heat dissipation, which is difficult to manufacture and increases flow resistance, failing to meet the increasingly stringent requirements of modern industry for direct cooling plates for refrigerant.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a refrigerant direct cooling plate with reasonable structure, simple processing and low flow resistance.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A refrigerant direct cooling plate includes an upper shell, a lower shell, and several thin sheets. The upper shell and the lower shell are arranged vertically. The lower shell has several strip-shaped grooves along its length on the side facing the upper shell, and each strip-shaped groove contains one of the thin sheets. The sheet includes a bottom, a first inclined portion and a second inclined portion inclined along the edge of the bottom, and a plurality of protrusions disposed on the bottom or the first inclined portion and the second inclined portion. The angle between the first inclined portion and the second inclined portion and the bottom is greater than or equal to 5 degrees, and the thickness of the sheet is greater than or equal to 0.1 mm.

[0007] As a further embodiment of this utility model, the end faces of the first inclined portion, the second inclined portion, and the lower housing are located on the same horizontal line.

[0008] As a further embodiment of this utility model, there is an arc transition between the first inclined portion and the bottom, and between the second inclined portion and the bottom.

[0009] As a further embodiment of this utility model, the arrangement of the protrusions is either regular or irregular, or a combination of regular and irregular arrangements.

[0010] As a further embodiment of this invention, the distance between two adjacent protrusions is greater than or equal to 1 mm.

[0011] As a further embodiment of this invention, the protrusion is a rounded transition protrusion.

[0012] As a further embodiment of this utility model, the upper shell, the lower shell, and the sheet are all made of one of aluminum, copper, or stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Due to the aforementioned structural design, namely, the lower shell is provided with several strip grooves, and each strip groove is provided with a thin plate, the thin plate includes a bottom, a first inclined part and a second inclined part, and a protrusion. When the refrigerant flows on the thin plate, the protrusion on the thin plate causes the refrigerant to change its flow direction, enhances the refrigerant transport effect, and turbulents the refrigerant. At the same time, the protrusion can change the cross-sectional area of ​​the flow channel, change the pressure of the refrigerant when it flows through the protrusion, change the fluid state of the refrigerant, and enhance the heat dissipation effect. It is not only structurally reasonable, but also easy to process and has low flow resistance. Attached Figure Description
