Description
Technical field
The utility model belongs to thermal balance machine set technology field, and in particular to a kind of dedicated thermal balance unit of freezer.
Background technique
The dedicated thermal balance unit of freezer is that a kind of low-pressure steam by the refrigerant in refrigeration system is sucked by compressor,
And it is discharged into condenser after boil down to high steam, the heat of refrigerant releasing is taken away, high pressure refrigerant vapor is made to be condensed into high pressure
Liquid, highly pressurised liquid enters evaporator by copper pipe, and evaporates under corresponding low pressure, draws the heat of surrounding, while fan
Heat exchange is carried out between so that air is constantly entered the fin of evaporator, and the air to turn cold after heat release is sent in freezer, realizes heat
Exchange equilibrium is measured, but the dedicated thermal balance unit of current freezer still has a little shortcoming.
The dedicated thermal balance unit of current freezer when in use, evaporator back to the side of fan due to the attachment of dust,
In addition inner cavity humidity is excessive, air flowing is poor, it is easy to tie one layer of thin frost, cause evaporator that can not carry out heat with the external world
Exchange, thermal balance is hindered, but also the temperature that the temperature of freezer does not reach requirement, greatly reduces the effect of refrigeration；And
General evaporator is the parallelpiped assembled by U-tube, and surface area is greater than the area of fan, when fan brushes, gas
The cold air that stream is taken away is less, so that heat exchange coefficient substantially reduces；General condenser is all to generate gas by axial flow blower
Stream cools down, and the noise of generation is larger, and when outdoor temperature is higher, and also undesirable, etc. problem need cooling effect
We solve.
