Problems solved by technology

[0005] Due to the thicker cold plate in the above method, it affects the furnace loading capacity during vacuum brazing. On the other hand, because the cold plate needs to cut off more than 1 / 2 of its thickness, it causes serious waste of materials and prolongs the processing cycle.
Therefore, the traditional frame-type cold plate and its processing method can no longer meet the requirements of customers and the market. It is particularly important to update and improve the energy-saving frame-type cold plate and its processing method.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0030] Such as Figure 4 As shown, the frame-type cold plate includes sequentially connected slot substrates, flat substrates (such as Figure 8 ) and framework 2 (such as Figure 9 and Figure 10 ); the surface of the trough base plate is provided with two mirror-symmetrical water channels that are not closed head to tail, each water channel includes six parallel and equal width vertical water channels of unequal length connected end to end, and the vertical water channels pass through horizontal water channels or arcs The water channels are connected; the flat base plate is a flat piece, parallel to the plane of the tank base plate and brazed to form a cold plate base; the frame 2 is a rectangular frame, and its four edges are connected to the cold plate base through friction stir welding.

[0031] Such as Figure 7 , specifically, each water c...

Abstract

The invention discloses a frame-type cold plate and a processing method thereof. Water channels with optimized connection sequence and shape are arranged on the groove base plate of the frame-type cold plate. When processing the cold plate, the following sequence is adopted: groove base plate, flat base plate and frame Separate processing—cleaning of groove substrate and flat substrate—assembly of groove substrate and flat substrate—vacuum brazing of groove substrate and flat substrate to form cold plate substrate—heat treatment of cold plate substrate—levelling of cold plate substrate—cold plate substrate and Frame Friction Stir Welding - Machining - Airtightness - Anodizing - Cleaning - Submission. The invention improves the heat exchange efficiency of the cold plate, reduces the processing cycle of directly processing the thick plate into a frame, reduces the waste of raw materials at the same time, reduces the thickness of the cold plate blank, and increases the furnace loading capacity of vacuum brazing to achieve The purpose of saving energy and reducing consumption.

Description

technical field [0001] The invention relates to the technical field of an aluminum frame-type cold plate, in particular to an energy-saving frame-type cold plate and a processing method for the cold plate. Background technique [0002] Frame type cold plate is a new type of high-efficiency heat conduction equipment. It is widely used in aerospace, aviation, laser, high-speed rail, wind power, electric power, construction machinery, medical treatment, petrochemical and other fields. As the cold plate application market becomes wider and wider, on the one hand, the traditional structural cold plate can no longer meet the requirements of heat transfer performance in some high-demand occasions; on the other hand, it is facing great pressure in terms of production cycle and production cost. The frame-type cold plate production process further saves energy and reduces consumption and improves efficiency. [0003] Such as figure 1 As shown, it is the main waterway layout form of...
