Description
Technical Field
The utility model relates to a quick-witted case heat dissipation technical field especially relates to an electric elements's heat abstractor.
Background
Today, with the rapid development of the electrical industry, an electrical drive case with high power and small size becomes more and more the mainstream trend, and under the limitation of the whole size, a new requirement is also put forward on the heat dissipation technology of the case. Generally, the heat dissipation manner of the drive case includes air cooling heat dissipation, water cooling heat dissipation, insulating liquid immersion heat dissipation and the like. Air cooling heat dissipation is the most common, and the electric driving machine box of a common machine adopts an air cooling heat dissipation scheme; the water-cooling heat dissipation module has better heat dissipation performance, and is generally designed for special equipment with large heat productivity; the immersion heat dissipation of the insulating liquid is generally used in environments with huge heat productivity or special requirements on the temperature stability and precision of equipment.
The air cooling and heat dissipation are commonly used, but the air cooling and heat dissipation have self limitations. For example, chinese patent CN102548274A discloses an electric control box, which uses a first heat dissipation air duct formed by an air inlet and an air outlet to dissipate heat from the surface of an electrical component inside the electric control box. However, this structure is affected by the ambient temperature, and the air-cooled heat dissipation cannot well exert all the performance of the driver; and the turbo fan rotating at a high speed causes a great deal of noise.
The water-cooling heat dissipation performance is good, but the water-cooling module is generally designed for special equipment. For example, chinese patent CN203554335U discloses a dual-motor driver, which improves the power density of the driver by disposing the power components of two sets of driver assemblies on the upper and lower surfaces of a water-cooled heat sink, and the design is a proprietary design of the driver, and has low universality, and the water path and the circuit are concentrated together, and once the interface leaks, the device is easily short-circuited. At present, the water-cooling heat dissipation structure generally adopts the design, and a water path and a circuit cannot be well distinguished, so that potential safety hazards exist.
Insulating liquid immersion heat dissipation is the most efficient heat dissipation method at present. For example, chinese patent CN103298312B discloses a two-phase submerged heat dissipation device, a communication apparatus and a manufacturing method thereof. However, the heat dissipation method is complicated to install and use, has high requirements on the insulating medium, risks of short circuit are caused once the insulating medium is doped, and the use cost is far higher than that of other heat dissipation methods.
