Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, specifically a multi-channel heat sink. Background Technology

[0002] Multi-channel heat sinks are thermal management devices used to improve heat exchange efficiency and are widely used in electronic equipment, automobiles, and industrial equipment. Their key feature is the use of multiple channels or pathways to increase the contact area between the coolant and the heat sink surface, thereby improving heat transfer efficiency.

[0003] Existing multi-channel heat sinks typically consist of a base plate and multiple heat dissipation fins. These fins create a multi-channel heat dissipation effect. During heat dissipation, the base plate is usually bolted to the heat-generating part. Heat is conducted from the base plate to the heat dissipation fins and then dissipated outwards from the fins. However, the heat dissipation of the fins is achieved through natural air cooling, which has poor efficiency, resulting in poor overall heat dissipation performance. Therefore, we propose a multi-channel heat sink. Utility Model Content

[0004] The purpose of this invention is to provide a multi-channel heat sink to solve the problem mentioned in the background art where the heat dissipation of heat sink fins is poor due to natural air cooling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel heat sink, comprising a plate body, side holes on the sidewall of the plate body, multiple heat sink fins on the top of the plate body, insertion holes on the sidewall of the heat sink fins, an inlet pipe at one end of the heat sink fins, a return pipe at the other end, a connector at the input end of the inlet pipe, a first cooling pipe on the sidewall of the inlet pipe, a second cooling pipe at the output end of the first cooling pipe, and a support block fixed to the sidewall of the plate body.

[0006] Preferably, a gasket is provided between the first cooling pipe and the second cooling pipe, and a connector is fixed to one side wall of the cooling pipe.

[0007] Preferably, the outer wall of the connector is provided with a sealing strip, the connector is fitted inside the second cooling pipe, and the second cooling pipe is fixed to the side wall of the return pipe.

[0008] Preferably, the top of the plate is provided with mounting holes, and the plate has a rectangular parallelepiped structure.

[0009] Preferably, the top of the heat dissipation fins is provided with heat dissipation grooves, and the top of the liquid inlet pipe is provided with fastening plates that cooperate with the heat dissipation fins.

[0010] Preferably, the first cooling pipe and the second cooling pipe are fitted inside the heat dissipation fins, and an airflow channel is provided between the two heat dissipation fins.

[0011] Preferably, the top of the support block is provided with a baffle that cooperates with the liquid inlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model provides an insertion hole on the side wall of the heat dissipation fins of the heat sink, and provides a cooling pipe one and a cooling pipe two in conjunction with the insertion hole. The flow of coolant in the cooling pipe one and the cooling pipe two is realized through the liquid inlet pipe and the return pipe, so that the heat on the heat dissipation fins can be carried away by the flowing coolant, thereby enabling the heat on the heat dissipation fins to dissipate more quickly and improving the heat dissipation effect of the multi-channel heat sink.

[0014] 2. When installing the liquid cooling structure composed of cooling pipe one and cooling pipe two, the second cooling pipe can be inserted and the return pipe fixed. Then, the first cooling pipe is inserted into the insertion hole. At this time, the connector is inserted into the inside of the second cooling pipe to connect the first cooling pipe and the second cooling pipe. Then, the inlet pipe is tightened. At this time, the installation of the liquid cooling structure is completed. The overall liquid cooling structure is a modular design, which facilitates the disassembly, inspection and maintenance of the liquid cooling structure and improves the convenience of using multi-channel heat sinks.
