Design method of water-cooling radiator

Abstract

The invention provides a planar water-cooling radiator capable of cooling an electronic component. The water-cooling radiator consists of two aluminium plates or copper plates, which are connected and fastened through bolt. Windscreen sealant is smeared at the connection position for improving the sealing effect. Rotary type slots which are communicated mutually are processed on the opposite planes of the two plates to form water passages. A water source and external radiators are connected through a water inlet and a water outlet to form a cooling loop so as to cool the heating electronic component attached onto the cooling loop.

Description

technical field [0001] The invention relates to the technical field of cooling of electronic components, in particular to a design method of a water cooling radiator. Background technique [0002] At present, the production and processing of water cooling radiators are generally carried out in two ways, that is, integral drilling and side seam welding of two cooling plates. [0003] The most prominent problem of the first method is that it is easily limited by the length of the drill bit, and it cannot manufacture a radiator with a larger area or a complex shape of the cooling channel. If the world's more advanced technology of using a drill bit for curve drilling is adopted, it will not only increase the difficulty and complexity of the process, but also increase the cost of product processing due to the need to purchase special equipment.

Problems solved by technology

[0003] The most prominent problem of the first method is that it is easily limited by the length of the drill bit, and it is impossible to manufacture a radiator with a larger area or a complex shape of the cooling channel.

If the world's more advanced technology of using a drill bit for curve drilling is adopted, it will not only increase the difficulty and complexity of the process, but also increase the processing cost of the product due to the need to purchase special equipment.

[0004] Using the second processing method, welding the seams of the joint surfaces of the upper and lower heat sinks to form a radiator will inevitably encounter the following disadvantages: first, the heat sink will be deformed during welding, Affect the heat dissipation effect and sealing effect; second, in order to overcome the thermal deformation of the heat dissipation plate after welding, the machining allowance of the heat dissipation plate blank is bound to be increased, and then processed after welding to eliminate the deformation, resulting in cost increase and processing procedures Complicated; third, in the process of using this processing method, even if measures such as improving the welding process requirements and increasing the processing allowance are taken, welding blisters or processing through holes will inevitably appear, resulting in a high product rejection rate; Fourth, this processing method has higher requirements on welding technology, which increases the difficulty of processing, and puts forward high requirements on the technical level of workers, which undoubtedly increases the personnel input cost of the enterprise.
