Air-cooling and water-cooling dual-purpose heat sink

Abstract

The invention discloses an air-cooling and water-cooling dual-purpose heat sink. The heat sink comprises a substrate, wherein one surface of the substrate bulges outwards to form a heat conducting surface tightly contacted with a heating element, the other surface of the substrate extends upwards to form multiple strip-shaped fins, the strip-shaped fins are arranged on the substrate to form multiple wave-shaped channels in parallel from bottom to top and multiple linear channels in parallel from left to right, and an outer frame surrounding the strip-shaped fins is detachably mounted on the other surface of the substrate; an air-cooling outer frame of fans and a water-cooling casing can be arranged at the upper end and the lower end of the outer frame respectively, the strip-shaped fins are sealed and surrounded by the water-cooling casing, and water pipe joints are arranged at the upper end and the lower end of the water-cooling casing respectively. The heat sink has the advantages ofbeing good in heat sinking effect and capable of realizing water-cooling or air-cooling heat sinking.

Description

technical field [0001] The invention relates to a heat dissipation element, in particular to an air-cooled and water-cooled dual-purpose radiator which has good heat dissipation effect and can realize water-cooled heat dissipation or air-cooled heat dissipation. Background technique [0002] The existing technology provides several single cooling methods for the heat dissipation of the controller, including water cooling technology, forced air cooling technology, natural cooling, heat pipe heat dissipation and micro-channel heat dissipation, etc., which are selected according to the actual use situation. Water cooling is used for high-power heat dissipation. Forced air cooling is suitable for open spaces, natural cooling is used for small power components, and heat pipe and microchannel technology are suitable for special cases. For several single cooling methods, water cooling has a good heat dissipation effect, but it takes up space and increases weight; forced air cooling...

AI Technical Summary

Problems solved by technology

For several single cooling methods, water cooling has a good heat dissipation effect, but it takes up space and increases weight; forced air cooling technology has a better heat dissipation effect, but it needs to arrange fans and also takes up space; natural cooling is suitable for small spaces, but the heat dissipation effect is poor; The application range of heat pipe cooling technology is limited, and the cost of micro-channel technology is relatively high

Now high-power electric vehicles, forklifts and other heavy vehicles are widely used, and the power of the motor electronic control system has increased, but the existing heat dissipation technology can no longer meet the requirements, and it is necessary to pursue a heat dissipation device with higher performance; in addition, in general, the heat dissipation of the controller can only Choose a cooling method instead of changing the heat dissipation method according to the usage situation and power adjustment. For the situation where the power of modern cars varies greatly, a single heat dissipation method can no longer meet the use requirements.
