Problems solved by technology

[0003] At present, with the rapid development of high power and high integration of electronic components, the heat generated during their work is increasing, and the requirements for water-cooled plates are becoming more and more stringent, and the water-cooled plates in the form of brazing exist to a certain extent. The safety hazard of leakage, and the welding cost is very high, so it is very important to improve the safety of the water cooling plate and reduce the cost

Abstract

The invention discloses a modular rapidly-formed water-cooling plate which is characterized by comprising a main collecting chamber, at least one main cavity as well as a collecting chamber matched with the main cavity, wherein a plurality of flow paths which penetrate through the main cavity and are used for flow of a coolant are arranged in the main cavity; a coolant accommodating groove I is formed in one side, which is fixed with the main cavity, of the main collecting chamber, and a coolant accommodating groove II is formed in one side, which is fixed with the main cavity, of the collecting chamber; and the main collecting chamber and the collecting chamber are fixed on two sides of the main cavity respectively through friction stir welding. According to the modular water-cooling plate, the thermal resistance is satisfied, meanwhile, the machining difficulty and the machining cost are reduced, the safety is improved, and the normal operation of a power module is facilitated.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a modular rapid prototyping water cooling plate. Background technique [0002] In the prior art, the working mode of the water-cooled plate is as follows: the heat generated by the power module is transferred to the outer surface of the main cavity through its installation contact surface in the form of heat conduction, and then the heat is diffused from the outer surface of the main cavity to the main cavity in the form of heat conduction. On the inner surface of the cavity, the heat is finally transferred from the circulating coolant from the water-cooled plate to the external environment by means of convective heat exchange. When the entire system reaches thermal balance, the surface temperature of the main cavity will be maintained at the normal operating temperature of the power module. [0003] At present, with the rapid development of high power and high integration ...
