Anti-freezing heat exchange device

Abstract

The invention discloses an anti-freezing heat exchange device which comprises a box body, a heat exchanger core body, a water inlet flute pipe, a water outlet flute pipe and a fan, wherein the heat exchanger core body is arranged in the box body and is of a copper sleeve fin-type structure; the water inlet flute pipe is connected with the water inlet end of a copper pipe of the heat exchanger core body; the water outlet flute pipe is connected with the water outlet end of the copper pipe of the heat exchanger core body; the fan is arranged on the box body, is positioned at one side of the heat exchanger core body and can blow air towards the heat exchanger core body; the water inlet flute pipe is provided with a water inlet part extending out of the box body and an air release valve; and the water outlet flute pipe is provided with a water outlet part extending out of the box body and a drain valve. The anti-freezing heat exchange device has a simple structure, is easy to implement and has a good heat exchange effect; residual water in the heat exchanger core body can be well drained; and the anti-freezing heat exchange device has a good anti-freezing function.

Description

[0001] technical field [0002] The invention relates to the field of heat exchangers, in particular to an antifreeze heat exchange device. Background technique [0003] Water and air heat exchangers are generally used in an environment above zero, and the temperature of the circulating water inside the heat exchanger is very high and will not freeze, but the existing equipment of this type also has technical defects. When the heat exchanger is out of service And when it is in a sub-zero environment, if there is water remaining inside the heat exchanger, it is easy to freeze and damage the core of the heat exchanger, causing leakage of the heat exchanger. At present, the main method to solve this kind of problem is to add antifreeze to the circulating water flowing through the heat exchanger to prevent freezing of the circulating water in sub-zero environment. Although this method solves the problem of icing at low ambient temperature of the circulating water of the equipme...

AI Technical Summary

Problems solved by technology

Although this method solves the problem of icing at low ambient temperature of the circulating water of the equipment, it also increases the operating cost of the equipment (a large amount of antifreeze needs to be added), and at the same time, the heat transfer efficiency of the circulating water with added antifreeze is lower than that of pure water Much more, this also caused the decline of the heat exchange efficiency of the whole equipment, the heat exchange effect of the heat exchanger must be enhanced by increasing the area of ​​the heat exchanger core or increasing the flow rate of the circulating air, which not only increases the heat exchange efficiency of the heat exchanger volume, which exacerbates the increase in the cost of the heat exchanger
