Abstract

Aiming at the situation that the existing refrigerator compressor has high temperature rise when working in summer, the utility model provides a simple and effective heat dissipation device. The heat dissipation device utilizes a water bag contacted with the top of the compressor to form a heat dissipation medium via water according to fin heat dissipation theory for dissipating the heat of the compressor continually. Therefore, the running frequency and the running time of the compressor are reduced, electric energy is saved, and the service life of the compressor is prolonged. Due to variable shape 3, the water bag can be matched with the compressor having various types and the top with different shapes.

Description

Refrigerator compressor heat relewasing deivce

A kind of compressor for refrigeration sink.

Existing refrigerator adopts fully closed compressor.This compressor is not structurally considered the heat dissipation problem of itself emphatically, and during the broiling summer, the compressor case temperature can reach more than 80 ℃, and the temperature of shell built-in motor can reach about 100-120 ℃.If the environment radiating condition is bad, compressor operating time long (often occurring under the situation that temperature is low or temp controller breaks down of refrigerator setting), its temperature rise is taller.Compressor often is under the condition of high temperature works, and can cause following consequence: 1, at high temperature lubricating oil viscosity descends.When the viscosity in the time of 100 ℃ has only 50 ℃ 1/8, the rubbing surface oil film of moving element are difficult for forming, and have increased the wearing and tearing of parts, can make the lubricant oil carbonization simultaneously, and block system damages parts.2, cause the compression ratio increase of compressor, the gettering quantity of compressor is reduced, the circulating load of refrigeration agent reduces, thereby the refrigerating capacity reduction, causes the compressor operating time lengthening, and the number of times that turns round increases, thereby causes power consumption to increase the compressor lost of life.3, motor winding insulation aggravation is aging.Compressor electric motor is generally the E class B insulation, and operating temperature is lower than that life-span of 105 ℃ was about 20 years and life-span 115 ℃ the time reduces half.Therefore, the heat radiation situation of compressor directly has influence on all problems of life-span, energy consumption of compressor.

The purpose of this utility model is to provide a kind of cheap and simple and effective sink, thereby can make the compressor amount of saving energy, and increases the service life.

The utility model is made of radiator and water bag, and radiator and water bag have formed the inner chamber of device jointly.In the inner chamber of device, filled with cold water.Water bag is placed the top of compressor, and the water in the water bag absorbs the heat of compressor, and the fin of the heat of water on radiator dissipates.

It below is a specific embodiment of the present utility model.Accompanying drawing is the structure principle chart of device.Wherein, Fig. 1 is a front view, and Fig. 2 is a plan view, and Fig. 3 is the Unit Installation schematic representation.

Thin-walled (about 0.5mm) the plastics radiator 1 that adopts plastic uptake technology to make is the crown housing of a circular hollow.Eight wings that dispel the heat only draw in its bonding part 2 stretches out the tubulose heat radiation wing 3(figure of several hollows), the top of heat radiation wing 3 seals.The spherical crown shape water bag of making at the fluid-tight flexible film material of usefulness of lower end socket (is Polypropylence Sheet or the latex film of 0.3mm as thickness) of radiator 1 outer round surface 4.The socket place 5 of radiator 1 and water bag 4 is heat seals or is bonded together.Water bag 4 has constituted the inner chamber 6 that installs jointly with the radiator 1 that has the wing 3 that dispels the heat.In addition,, a upper end open is set at the top center place of radiator 1, the water injecting pipe 7 that lower end and inner chamber 6 communicate, its upper end open place clamp-ons a rubber seal plug 8.

When this device uses, at first extract sealing plug 8, cold water (being generally normal-temperature water) is poured into the inner chamber 6 of device from water injecting pipe 7, the priming charge amount is about 2/3rds of inner chamber 6 volumes.Then, with hand extruding water bag 4, the air that is about inner chamber 6 volumes 1/3rd is discharged from water injecting pipe 7, again sealing plug 8 is clamp-oned the oral area of water injecting pipe 7, the water that makes device inner chamber 6 is not to external leakage, at last, the water bag 4 of device just is being placed on the spherical top 9 of compressor for refrigeration, and make heat radiation wing 3 straight up, at this moment, because water bag 4 malleations are on the top 9 of compressor, thereby the volume reducing of inner chamber 6, priming charge just has been full of whole inner chamber 6 basically, and this has just constituted is the fin radiating mode of medium with water.When compressor operating, heat passes to water bag 4 by its top 9, so water is heated, and the heat of water is to dissipate by heat radiation wing 3, and the continuous circulative convection of the water of inner chamber 6 causes the temperature of compressor to reduce greatly.

Water bag 4 in the utility model has shape variable, although its top shape of the compressor of different model is variant, but as long as its top surface is smooth, can both coincide well with water bag 4 and contact, thereby the heat of compressor is distributed effectively, and therefore, the utility model is simple in structure, cheap, easy to use, effect is obvious, can be widely used in the radiating and cooling of compressor for refrigeration, thereby reach the purpose that makes compressor for refrigeration energy-saving, service life prolonged.
