Technical Field

The invention relates to a sound-proof housing, in particular to a heat dissipation type sound-proof housing.

Background

The compressor has all obtained extensive application in various refrigeration and heating equipment for improve gaseous refrigerant's pressure and temperature, the compressor can produce a large amount of noises at the in-process of operation, and radiate to the environment through the equipment casing, reduced user's comfort level and experienced, also can bring the influence to the whole quality of equipment simultaneously. In order to reduce the noise generated by the compressor in operation, the sound-proof cover is installed outside the compressor, and the sound-proof cover is approximately matched with the appearance of the compressor, so that the sound-proof effect can be achieved, and the space occupied by the compressor assembly can not be increased as much as possible. A sound-proof housing that adopts among the prior art includes the cover body and sound absorbing layer, and sound absorbing layer is many to be made by porous sound absorbing material such as foaming sponge, and the heat conductivility is poor, leads to compressor during operation temperature to be difficult to the conduction and easy overheated.

Disclosure of Invention

The invention aims to provide a sound-proof shield capable of effectively reducing the temperature rise of a compressor.

The purpose of the invention is realized by the following technical scheme: the utility model provides a heat dissipation type sound-proof housing, includes the cuboid support, forms the installation cavity in the support, and the inner wall of support covers there is porous puigging, porous puigging's surface is equipped with a plurality of heat absorption pieces.

The support frame can be made of any rigid material, and mainly has the functions of protecting the compressor and providing support for other structures of the sound-proof housing. Necessary openings (for the insertion of the compressor), wire holes (for the connection of the lines) can also be included. The porous soundproof layer can be made of any porous soundproof material, such as foamed plastic, sponge, cotton and rubber foam, can be adhered to the inner wall of the bracket by using an adhesive, and can also be fixed in the bracket by using a structure such as a nail. Particularly, the surface of the porous sound insulation layer is provided with a plurality of heat absorption blocks which are made of materials with high specific heat capacity, so that heat in the installation cavity can be absorbed to a certain extent without great change of temperature, and the temperature in the installation cavity can be effectively controlled. The heat absorption device can be made of materials with high specific heat capacity such as organic glass, ceramics, mica and aluminum alloy and certain heat conductivity. The heat absorbing block can be mounted on the surface of the porous soundproof layer by means of embedding, bonding and the like.

Furthermore, the bottom of the heat absorption block is connected with a heat conduction strip, and the tail end of the heat conduction strip extends out of the support.

The heat conducting strip can be made of materials with good heat conductivity, such as aluminum alloy and the like. When the heat absorption piece chooses the good material of heat conductivity such as metal to realize, can set up the heat conduction strip, the heat conduction strip can be with the heat conduction of heat absorption piece outside the sound-proof housing, accomplish the heat exchange with the external world and avoid installing the intracavity high temperature.

Furthermore, the cross-sectional area of the heat conducting strip is reduced from inside to outside.

The heat conduction efficiency of the controller is controlled by limiting the sectional area of the heat conduction strip, and the heat conduction strip is prevented from conducting heat to the inside of the sound-proof shield reversely when the external temperature is high. And the smaller contact area is also beneficial to the conduction of noise to the outside through the heat conducting strips.

Preferably, the bracket is provided with a plurality of ventilation through holes.

When the temperature in the sound-proof cover is too high, the internal gas expands to cause the internal pressure to rise (according to an ideal gas equation), the ventilation through holes can realize a certain exhaust effect, so that the internal and external pressures can be balanced, and a certain heat dissipation (heat convection) function is realized.

Preferably, the heat absorbing block comprises an outer shell and a hydrogel block filled in the metal outer shell.

The hydrogel has larger specific heat capacity, and also has certain sound insulation effect.
