Abstract
The utility model discloses a kind of frost removal type freezer evaporators, its enclosure interior assembles fin, the lateral surface of the shell is equipped with the heat generating device for removing frost layer on fin, heat generating device connects air hose, air hose offers several heat outlets and heat outlet is towards fin, and defrosting effect is good, and when replacement heat generating device, it need not together be taken out together with the fin of enclosure interior, replace fast and easy.
Description
Technical field
The utility model belongs to freezer equipment, more particularly to a kind of freezer evaporator.
Background technology
Currently used freezer evaporator Defrost method substantially has following several：
Electric heater defrosting：Electric heating tube using inside arrangement makes frost layer melt fin heats.This method system is simple,
Operation is also more convenient, but every square of heat exchange area of freezer evaporator is about fitted on the electric heating tube of 40~100W, and power consumption is too big,
It is also very big to the influence of fluctuations of library temperature, it is not energy-efficient；Defrosting electric heating tube power is very big, the poor quality of heating tube or when use
Between it is long, be easy to burn out or even cause fire, there are serious security risks for electric heater defrosting, replace trouble after damage, are applicable in
In miniature cold storage, installation is simple, convenient.
Water defrosting：It is sprayed water to freezer evaporator fin using water pump or water injector, frost layer is made to be melted simultaneously by the heat of water
The method washed out.Water defrosting is easy to operate, the time is short, is very effective Defrost method.In the very low freezer of temperature, pass through
Defrosting repeatedly, water temperature is too low, can influence the effect of defrosting；If frost is not rinsed within the set time, in freezer
After evaporator normal work, frost layer may become ice sheet, keep next defrosting more difficult, be suitable for large cold storage.
Hot working medium defrosting：The superheated refrigerant steam with higher temperature being discharged using compressor, by oil eliminator
Afterwards, into freezer evaporator, evaporator is temporarily treated as into condenser, the heat released when being condensed using hot working fluid will steam
The frost layer for sending out device surface is melted.The refrigerant and lubricating oil accumulated originally in evaporator simultaneously, pressure is returned to by high-pressure refrigerant
Contracting machine, applies in general to cold storage medium.
Freezer evaporator uses electrothermal tube defrost, if electrothermal tube damages, needs to extract out from the side of freezer evaporator
Come, is then replaced, but urban small freezer stock size is very compact now, freezer installs the position of freezer evaporator only
There are 1.6 meters of freezer evaporator length just there are 1.4 meters, after such freezer evaporator defrost electrothermal tube damage, can not just take out,
Lead to not repair.
Utility model content
In order to solve defect of the existing technology, the purpose of this utility model is to provide a kind of freezers effectively to defrost
Evaporator.
The utility model realize above-mentioned purpose the technical solution adopted is that：A kind of frost removal type freezer evaporator, including shell,
Enclosure interior assembles fin, and the lateral surface of the shell is equipped with the heat generating device for removing frost layer on fin, heat generating device
Air hose is connected, air hose offers several heat outlets and heat outlet is towards fin.
Further, the heat generating device is made of fan and Electrothermic wire, and the Electrothermic wire connects air hose.
The air hose is located at bottom in shell.
The air hose is located at case inside face.
Implement technical solutions of the utility model, since heat generating device is arranged in hull outside face, not only defrosting effect is good, and
It when replacing heat generating device, need not together be taken out together with the fin of enclosure interior, replace fast and easy.
Description of the drawings
Fig. 1 is the structural schematic diagram of freezer evaporator.
Specific implementation mode
As shown in Figure 1, freezer evaporator is made of shell 1, fin 2, fan 3, Electrothermic wire 4 and air hose 5.
The lateral surface of the mounted inside fin 2 of shell 1, shell 1 is equipped with Electrothermic wire 4 and fan 3.Electrothermic wire 4 connects
Air duct 5, air hose 5 stretch into the lower section in shell 1 and positioned at fin 2.Air hose 5 towards fin offers several heat outlets
6.Electrothermic wire and fan are due to being located at hull outside, as damaged, directly replace entire heating blowing.
After freezer evaporator enters defrost pattern, compressor and wind turbine are stopped, and Electrothermic wire and fan are powered on,
The hot wind of generation is sprayed into Gas inlet tube from heat outlet, the principle risen using hot-air, is steamed into the freezer for being covered with frost layer
It sends out on device fin, hot-air blows frost, leads to frost chemical conversion water, to remove frost, this flow of completion defrost.
