Description
Technical field
It the utility model is related to enclosed cooler technical field, and in particular to a kind of by gravity Auto-drainage frost-cracking-preventing
Enclosed cools down unit.
Background technology
Enclosed cooling unit is mainly made of heat exchanger, wind turbine and control system.Wherein, the heat exchanger is usually by round
Copper pipe and aluminum fin-stock are process.In general, the cooling medium that uses of cooling unit is water, there are the problem of be：In environment temperature
During less than 0 degree, if enclosed cooling unit do not working, the water inside heat exchanger will freeze, due to water after icing volume
Increase, therefore heat exchanger tube will be caused（Round copper pipe）Breakage is split up, so in the colder area of weather, it usually needs in cooler
Filling antifreezing agent in group, freezes to avoid cooling medium.
Separately have a kind of heat exchanger with certain anti-freezing property, its cooling coil by oval copper pipe and aluminum fin-stock processing and
Into.Designed by the oval cross section of copper pipe, after water freezing in copper pipe, copper pipe will come by deformation in response to cooling medium
Expansion, the ovality of its cross section of copper pipe after deformation can diminish, but be unlikely to be split up copper pipe.But, which also can only
Tackle accidental one twice to freeze, if there is repeatedly freezing, also result in copper pipe and be split up.In addition, the resistance to pressure of elliptical tube
Also it is poorer than pipe, rise connect when, the compactness of elliptical tube and aluminum fin-stock is poorer than pipe, so the heat exchange efficiency of product is relatively low,
It cannot function as the first choice of heat exchanger tube.
Therefore, above-mentioned the shortcomings of the prior art how is solved, is become as the class to be researched and solved of the utility model
Topic.
