Description

Technical Field

[0001] This utility model relates to the field of power electronic energy storage photovoltaic liquid cooling plate technology, specifically a liquid cooling plate with microchannels. Background Technology

[0002] A liquid cooling plate for power electronics is a cooling device used to dissipate heat from power electronic equipment. It primarily transfers heat through a liquid coolant to maintain stable operation. Liquid cooling plates play a crucial role in power electronic equipment, especially in applications with high power density and high heat flux. A liquid cooling plate is a device that transfers heat through fluid. Its basic structure includes internal flow channels, heat sinks, and inlet / outlet interfaces for the fluid. The liquid cooling plate has micro-channels within it through which the coolant flows, carrying away the heat generated by the power electronic equipment and dissipating it through an external cooling system. To improve the heat dissipation efficiency of the equipment, a liquid cooling plate is needed. However, existing liquid cooling plates still have the following shortcomings:

[0003] For example, the utility model with publication number CN220527021U discloses a liquid cooling plate. This utility model reduces the overall temperature difference of the battery pack by partitioning the cooling motherboard to ensure the normal operation of the battery pack. However, similar to the prior art of the above application, when existing liquid cooling plates are used, most liquid cooling plates do not have a turbulence structure inside, which weakens the heat dissipation effect of the liquid cooling plate. At the same time, the fluid tends to be excessively concentrated and stagnant in specific areas, resulting in a decrease in the practicality and efficiency of the liquid cooling plate.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a liquid cooling plate with microchannels. Utility Model Content

[0005] The purpose of this invention is to provide a liquid cooling plate with microchannels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid cooling plate with microchannels, comprising a cooling plate body, a first microchannel, and a second microchannel. A first plug body is provided at the front end of the cooling plate body, and a flow channel body is formed inside the first plug body. A water inlet pipe is provided on the upper left side of the first plug body, and a water outlet pipe is provided on the upper right side of the first plug body. A second plug body is provided at the rear end of the cooling plate body, and water guiding holes are formed at both ends inside the cooling plate body. A flow channel is provided inside the cooling plate body, and liquid guiding grooves are formed at both ends of the flow channel. A first microchannel is provided on the left side inside the flow channel, and a second microchannel is provided on the right side inside the flow channel.

[0007] Furthermore, the outer side of the cold plate body and the outer side of the first plug body are horizontally distributed, and the cold plate body and the first plug body are fixedly connected by bolts.

[0008] Furthermore, the water inlet pipe is perpendicular to the first plug body, and the water inlet pipe is fixedly connected to the first plug body by bolts.

[0009] Furthermore, the outer side of the second plug body is horizontally distributed with the outer side of the cold plate body, and the outer side of the second plug body is closely attached to the outer side of the cold plate body.

[0010] Furthermore, the water guiding holes are hollow cylindrical in shape, and the water guiding holes are equidistantly distributed at both ends inside the cold plate body.

[0011] Furthermore, the external dimensions of the guide channel are adapted to the internal dimensions of the cold plate body, and the guide channel and the cold plate body are embedded in each other.

[0012] Furthermore, the first microchannel is embeddedly connected to the guide channel, and the first microchannel is fixedly connected to the guide channel by bolts.

[0013] Furthermore, the first microchannel and the second microchannel are equidistantly distributed inside the guide channel, and the positions of the first microchannel and the second microchannel are staggered.

[0014] This invention provides a liquid cooling plate with microchannels, which has the following advantages:

[0015] 1. By setting the first plug body, this utility model enables the coolant to be delivered into the flow channel body opened inside the first plug body through the water inlet pipe when the liquid cooling plate with microchannel is used. The coolant inside the flow channel body is delivered to the cold plate body through the water guide hole, and the coolant flowing inside the cold plate body can be discharged through the water outlet pipe. This enables the coolant to circulate inside the liquid cooling plate, thereby cooling the equipment and improving the overall practicality and efficiency of the liquid cooling plate.

[0016] 2. This utility model, through the setting of the first microchannel, enables the guide channel to be fixedly installed inside the main body of the liquid cooling plate with the microchannel by fastening bolts when the liquid cooling plate with the microchannel is used. The liquid guiding grooves opened at both ends of the guide channel are adapted to and connected with the water guiding holes, so that the coolant can enter the guide channel through the water guiding holes and the liquid guiding grooves. The first microchannel and the second microchannel are fixedly installed inside the guide channel. After the coolant enters the guide channel, it is turbulent through the first microchannel and the second microchannel. The flow rate is adjusted by the cross-sectional size of the microchannel, so as to achieve uniform heat dissipation. Attached Figure Description

The coolant circulating inside the cold plate main plate 1 can be discharged through the water outlet pipe 5, thereby realizing the circulation of coolant inside the liquid cooling plate, which can cool and reduce the temperature of the equipment and improve the overall practicality and efficiency of the liquid cooling plate.
