Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.
As shown in fig. 1 to 3, the utility model provides a utmost point ear cooling device, include with the heat conduction pad 2 of the laminating of copper bar 3, with the cooling plate 1 of the laminating of heat conduction pad 2 and set up inlet tube 5 and outlet pipe 6 on cooling plate 1, cooling plate 1 is inside to be equipped with let the coolant liquid pass through and with the cooling water course of inlet tube 5 and outlet pipe 6 intercommunication, and cooling plate 1 sets up two and two cooling plates 1 and is arranging side by side.
Specifically, as shown in fig. 1 to 3, the automotive power battery module mainly includes an outer case 4 and a plurality of battery modules disposed inside the outer case 4. Copper bar 3 and battery module's electric core utmost point ear welded connection, copper bar 3 is located the top of shell body 4. When the assembly, use laser welding technique with copper bar 3 weld on electric core utmost point ear, then evenly paste heat conduction pad 2 on copper bar 3, guarantee to compress tightly to paste really, the middle bubble that does not have, fix cooling plate 1 again on heat conduction pad 2, guarantee to compress tightly to paste really, the middle bubble that does not have.
As shown in fig. 1 to 3, in the present embodiment, two thermal pads 2 are provided, and each thermal pad 2 is located between one cooling plate 1 and one copper bar 3. The heat conduction pad 2 is a rectangular block structure, the material of the heat conduction pad 2 is silica gel, and the heat conduction pad 2 is located inside the outer shell 4. Cooling plate 1 is the rectangle flat board, and heat conduction pad 2 presss from both sides between cooling plate 1 and copper bar 3, and heat conduction pad 2 is located cooling plate 1's below, and the top surface of heat conduction pad 2 is laminated with cooling plate 1's bottom surface, and the bottom surface of heat conduction pad 2 is laminated with copper bar 3. The two cooling plates 1 are arranged side by side, the length directions of the two cooling plates 1 are parallel, and the heat conducting pad 2 is arranged below each cooling plate 1. The pole lug cooling device with the structure has the advantages of simpler structure and more convenient assembly while ensuring the cooling effect.
As shown in fig. 1 to 3, the cooling water passage is U-shaped, and the water inlet pipe 5 and the water outlet pipe 6 are provided at the same end of the cooling plate 1. The cooling water course begins to extend to the other end of cooling plate 1 along the length direction of cooling plate 1 at the inside of cooling plate 1 from the one end of cooling plate 1, and inlet tube 5 is connected with the water inlet of cooling water course, and outlet pipe 6 is connected with the delivery port of cooling water course, and inlet tube 5 is arranged in guiding the coolant liquid to the cooling water course, and the coolant liquid in the cooling water course discharges through outlet pipe 6.
