Abstract

The invention provides a noise reduction device applied to refrigeration equipment. The refrigeration equipment comprises a compressor, a condenser, a capillary tube and an evaporator, and refrigerantcirculates among the compressor, the condenser, the capillary tube and the evaporator. The noise reduction device is connected between the capillary tube and the evaporator, the noise reduction device comprises at least one transition tube, the at least one transition tube forms passages allowing the refrigerant to flow therethrough, and the tube diameter of the passages gradually increases in the direction from the capillary tube to the evaporator. The invention further provides the refrigeration equipment with the noise reduction device. According to noise reduction device and the refrigeration equipment with the noise reduction device, the transition tubes form the refrigerant circulating passages with the inner diameter gradually increasing in the direction from the capillary tube tothe evaporator, so that the flow rate of the refrigerant flowing from the capillary tube to the evaporator can be reduced, and the effect of reducing the noise of the refrigeration equipment is achieved. In addition, the noise reduction device also comprises damping glue to achieve the effect of damping and sound absorbing, thereby further reducing the noise of the refrigeration equipment.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a noise reduction device for reducing the noise of a refrigeration system and refrigeration equipment with the noise reduction device. Background technique [0002] Small refrigeration equipment such as dehumidifiers, refrigerators, freezers, and wine cabinets in daily life generally use capillary tubes as the throttling parts of the refrigeration system. These refrigeration equipment often produce periodic noise during operation, because the refrigerant passes through the capillary tube. When entering the evaporator after throttling and depressurization, due to the small diameter of the capillary, the flow rate of the refrigerant is very fast when flowing in the capillary, and when entering the evaporator, the diameter of the evaporator suddenly becomes larger The sound of liquid injection is formed at the outlet, and the sound of liquid injection is periodic with the star...
