Embodiment Construction

[0046] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0047] Please refer to figure 1 , figure 1 It is a flow chart of making a heat exchanger according to an embodiment of the present invention. The heat exchanger in this embodiment can be applied to the liquid-cooled heat dissipation module in the servo cabinet to dissipate heat from the heat source in the servo cabinet. Among them, the production process of the heat exchanger is as follows:

[0048] First, a base material is provided, the base material includes a base portion and a processing portion located on the base portion, the processing portion has a top surface, the base portion has a bottom surface, and the top surface and the bottom surface are located on opposite sides of the base material , and the distance from the top surface to the bottom surface substantially decreases gradually along a first direction (step...

Abstract

The invention discloses a heat exchanger and a manufacturing method thereof, wherein the heat exchanger comprises a base part and a plurality of fins, wherein the fins are arranged on the base part side by side, each fin is provided with a top edge which is far away from the base part, the distances between the top edges and the base part are reduced gradually in a first direction, the top edges sink downwards and together form one or more grooves, and the groove extends in a second direction intersecting the first direction. According to the structure, waste material produced by cutting and processing of the heat exchanger is prevented from clamping into the fines and causing blockage of the flow passage of the heat exchanger.

Description

technical field [0001] The invention relates to a heat exchanger and a manufacturing method thereof, in particular to a heat exchanger with fins and a manufacturing method thereof. Background technique [0002] Currently, a heat dissipation module used in a rack server mostly adopts an air-cooled heat dissipation mode. The operating principle of the air-cooled heat dissipation mode is to install cooling fins on multiple heat sources in the chassis, and to set corresponding cooling fan modules in the chassis. The forced heat convection generated by the operation of the cooling fan module is used to dissipate heat from the heat source. However, in such a heat dissipation mode, the ambient temperature at the location of the chassis is very important, because the airflow driven by the air dissipation module flows through the heat source to remove the heat energy generated by the heat source, and the temperature of the environment is raised. Therefore, the existing air-cooled a...
