No-hole and mute heat dissipation device of closed box body

Abstract

The invention discloses a no-hole and mute heat dissipation device of a closed box body, and belongs to the technical field of noise control and heat dissipation. The no-hole and mute heat dissipation device of the closed box body aims to improve the waterproof and dustproof performances of the box body and control heat dissipation noise under the premise of good heat dissipation. The no-hole and mute heat dissipation device of the closed box body comprises a heat sink, a semiconductor refrigeration piece, a heat pipe and the like, and is characterized in that the box body is closed and not provided with heat dissipation holes, a heat source tightly attached inside the box body and the heat sink seamlessly embedded into the box body are connected through the heat pipe, the heat sink embedded into the box body is closely attached to the semiconductor refrigeration piece on the outer side of the box body to dissipate heat, a stable cooling source is provided, heat conduction speed of a heat conduction tube is improved, and the whole heat dissipation device is not provided with any component generating noise and does not has processes generating the noise. The no-hole and mute heat dissipation device of the closed box body is simple and reasonable in structure, and applicable for no-hole and mute heat dissipation of the closed body.

Description

(1) Technical field [0001] The invention relates to a non-porous mute heat dissipation device of a closed box, belonging to the technical fields of noise control and heat dissipation. (2) Background technology [0002] For the heat dissipation of equipment, it is widely used in laboratory and actual production applications. At present, the heat dissipation of the cabinet relies on air cooling to blow the heat emitted by the equipment out of the heat dissipation holes of the cabinet. The cabinet has heat dissipation holes, which is not conducive to waterproof and dustproof in harsh environments. The heat dissipation method of Yue s520 (Happy type) desktop computer host belongs to this category; the second is to rely on water cooling method, the box body is opened with a circulating water pipe, and the heat in the box is taken away through water circulation, such as the ZHD- The heat dissipation method of 300M2 type high vacuum resistance evaporation coating machine belongs t...

Problems solved by technology

During the use of these two heat dissipation methods, the operation of the fan and water pump will generate noise. The third is to rely on the fins of the casing to dissipate heat, and the heat dissipation efficiency is limited. Especially when the ambient temperature is high, the lowest temperature of the cabinet can only maintain the same temperature as the ambient temperature Similar, it is not conducive to the stable operation of electronic equipment, etc., and even shortens the life of the equipment, causing fires. For example, the heat dissipation method of the 2XZ rotary vane vacuum pump produced by Zhejiang Wenzhou Yangzijiang Pump Industry Co., Ltd. belongs to this category.
