Water inlet and outlet structure of water cooling plate

Abstract

The invention discloses a water inlet and outlet structure of a water cooling plate, and relates to the technical field of liquid cooling plates, the water inlet and outlet structure comprises a connector assembly and a liquid collecting pipe, the connector assembly comprises an inserting pipe, an anti-falling pipe and a welding head, the inserting pipe is fixedly arranged at one end of the anti-falling pipe, the welding head is fixedly arranged at the other end of the anti-falling pipe, and the diameter of the welding head is larger than that of the anti-falling pipe; a vertical hole is formed in the welding head, an arc-shaped groove is formed in the bottom of the vertical hole, and the arc-shaped groove communicates with the anti-falling pipe; an arc-shaped connector matched with the arc-shaped groove is formed in the liquid collecting pipe, and the liquid collecting pipe is fixedly connected with the welding head through welding; by arranging the welding head on the connector assembly, the contact area between the connector assembly and the liquid collecting pipe is increased, the contact area between the water inlet and the water outlet and the liquid collecting pipe is increased under the condition that the width of the liquid collecting pipe is not increased, the welding reliability is improved, one-time welding of the whole product becomes possible, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a liquid cooling plate, in particular to a water inlet and outlet structure of a water cooling plate. Background technique [0002] As the power source of new energy vehicles, the battery module provides a steady stream of power for the vehicle during use. At the same time, the core component of the module will also emit heat continuously. If the heat cannot be dissipated in time, it will affect the module. Therefore, it is necessary to install a liquid-cooled plate on the battery module to dissipate heat. The liquid-cooled plate is usually provided with a liquid inlet and a liquid outlet to ensure that the internal coolant circulates and realizes cooling of the battery. Circulating heat dissipation of the module, the existing liquid cooling plate inlet and outlet are assembled on the liquid collection pipe, the space layout is compact, the width of the liquid collection pipe is small, and the flow rate o...

[0002] As the power source of new energy vehicles, the battery module provides a steady stream of power for the vehicle during use. At the same time, the core component of the module will also emit heat continuously. If the heat cannot be dissipated in time, it will affect the module. Therefore, it is necessary to install a liquid-cooled plate on the battery module to dissipate heat. The liquid-cooled plate is usually provided with a liquid inlet and a liquid outlet to ensure that the internal coolant circulates and realizes cooling of the battery. Circulating heat dissipation of the module, the existing liquid cooling plate inlet and outlet are assembled on the liquid collection pipe, the space layout is compact, the width of the liquid collection pipe is small, and the flow rate of the product is large, the inner diameter of the water inlet and outlet is large, resulting in the inlet and outlet and the liquid collection The contact surface of the tube is small, the welding reliability is poor, and secondary welding is required, and the efficiency is low
