Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling plates, in particular to a double-sided flat cooling plate structure for improving heat exchange efficiency. Background Art

[0002] Most existing cold plate heat exchangers consist of a temperature-stabilizing plate, a flow channel plate, and a water connector. Two main plates require one set of forming dies and two sets of trimming and punching dies. This is expensive and the process is cumbersome. Furthermore, only one side of the plate can accommodate the battery cells for heat exchange.

[0003] In the prior art, the flow channel plate is composed of a flow channel plate, a flat plate and two water joints. During the production process, one set of forming dies and two sets of blanking dies are required, resulting in high production costs. Utility Model Content

[0004] The purpose of the present invention is to provide a double-sided flat cold plate structure that improves heat exchange efficiency, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a double-sided flat cold plate structure for improving heat exchange efficiency, comprising a first flat plate and a second flat plate, a plurality of intermediate plates being arranged between the first flat plate and the second flat plate, and a medium inlet and a medium outlet being fixedly connected to one end of the first flat plate.

[0006] For further optimization, the plurality of intermediate plates are respectively composed of a first intermediate plate, a second intermediate plate, a third intermediate plate and a fourth intermediate plate which are arranged in a mirror image, and a fifth intermediate plate is provided between the third intermediate plate and the fourth intermediate plate.

[0007] Further optimized, the first middle plate, the second middle plate and the upper ends of the third middle plate and the fourth middle plate are fixedly connected by a first clamping portion.

[0008] In a further optimization, the third middle plate and the fourth middle plate are fixedly connected via a second clamping portion.

[0009] Further optimized, both sides of one end of the fifth middle plate are fixedly connected to the third clamping parts on one side of the lower end of the first middle plate and the second middle plate respectively.

[0010] In a further optimization, a plurality of flow channels are formed on two adjacent sides of the first middle plate, the second middle plate, the third middle plate, the fourth middle plate and the fifth middle plate.

[0011] As a further optimization, a plurality of pre-welding points are symmetrically provided around the first plate and the second plate.

[0012] Beneficial effects

[0013] The double-sided flat cold plate structure provided by the present invention improves the heat exchange efficiency. The liquid cooling plate is composed of two flat plates and an intermediate plate. The flow channel is formed by splicing the positions of the intermediate plates, thereby avoiding the production and manufacturing costs of the forming mold and the blanking mold. Due to the double-sided flat plate structural design, it can be placed inside the battery pack, and the battery cells are placed on both sides. The battery cells on both sides are cooled simultaneously by a liquid cooling plate, which effectively reduces the price of the entire battery pack and also increases the cooling efficiency of the liquid cooling plate when it is working. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0015] Figure 2 This is a schematic diagram of the intermediate plate structure of the present utility model. DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] Example

[0018] like Figure 1-2 As shown, a double-sided flat cold plate structure for improving heat exchange efficiency includes a first flat plate 1 and a second flat plate 2, with multiple intermediate plates arranged between the first flat plate 1 and the second flat plate 2, and a medium inlet 3 and a medium outlet 4 fixedly connected to one end of the first flat plate 1.

[0019] In this embodiment, the multiple intermediate plates are respectively composed of a first intermediate plate 6, a second intermediate plate 7, a third intermediate plate 8 and a fourth intermediate plate 9 which are arranged in a mirror image. A fifth intermediate plate 10 is provided between the third intermediate plate 8 and the fourth intermediate plate 9. The heat exchange flow channel is formed by assembling multiple intermediate plates, thereby avoiding the production and manufacturing costs of the forming mold and the blanking mold.

[0020] The first middle plate 6, the second middle plate 7 and the upper ends of the third middle plate 8 and the fourth middle plate 9 are fixedly connected by the first clamping portion 12, the third middle plate 8 and the fourth middle plate 9 are fixedly connected by the second clamping portion 14, and both sides of one end of the fifth middle plate 10 are fixedly connected to the third clamping portions 11 on one side of the lower ends of the first middle plate 6 and the second middle plate 7, respectively. Multiple middle plates are fixed by multiple clamping portions.

[0021] A plurality of flow channels 13 are formed on adjacent sides of the first intermediate plate 6 , the second intermediate plate 7 , the third intermediate plate 8 , the fourth intermediate plate 9 and the fifth intermediate plate 10 .

[0022] A plurality of pre-welding points 5 are symmetrically provided around the first plate 1 and the second plate 2 .

[0023] The middle plate is thicker than the two side plates, increasing the height of the flow channel to increase the flow of coolant in the flow channel, thereby more efficiently exchanging heat with the battery cells. If the flow channel height is ≥4mm, the middle plate is stacked with multiple layers to increase the flow channel height.

[0024] If the heat exchange capacity is insufficient, the width of the flow channel can be increased by adjusting the layout of the middle plate to achieve the purpose of increasing the flow rate and thus better heat exchange.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
