Description

A kind of finned tube evaporator
Technical field
The utility model relates to technical field of air-conditioning heat pumps, specially a kind of finned tube evaporator.
Background technique
When net for air-source heat pump units is run under low temperature environment in winter, there are frosts for outdoor fin-tube heat exchanger. With the thickening of frost layer, encryption, evaporator heat exchange performance can reduce quickly, greatly reduce unit heating performance and reliability. When on evaporator frosting to a certain degree when, it is desirable to unit switches to defrosting mode, and at this moment unit cannot achieve heating or full Load heating.Improve evaporation structure, surface appearance to inhibit or slow down Frosting rate, reduce frosting degree, extension defrosting week Phase etc. is of great significance to the heating performance and reliability that improve net for air-source heat pump units.
Utility model content
(1) the technical issues of solving
In view of the deficiencies of the prior art, the utility model provides a kind of finned tube evaporator, solves low in winter When running under warm environment, there are frosts for outdoor fin-tube heat exchanger, influence the problem of heat exchanger uses.
(2) technical solution
To achieve the above object, the utility model provides the following technical solutions: a kind of finned tube evaporator, including left end Plate, right end plate, copper pipe beam, refrigerant return-air equalizer line, the first fins set and the second fins set are equipped on the right side of the left side plate Right end plate is equipped with the first fins set, is equipped with second on the outside of first fins set between the left side plate and right end plate Fins set, is equipped with copper pipe beam between the left side plate and right end plate, the copper pipe beam runs through the first fins set and the second fin Group, refrigerant return-air equalizer line is equipped on the right side of the right end plate, and the refrigerant return-air equalizer line and copper pipe beam are interconnected.
Preferably, the left side plate is identical with the size of right end plate.
Preferably, the copper pipe beam is S-shaped is uniformly interspersed in the first fins set and the second fins set back and forth.
Preferably, first fins set is equidistantly evenly distributed between left side plate and right end plate, and the first fin Spacing between group is two to three millimeters.
Preferably, second fins set is placed on the inside of the first fins set, and the spacing between the second fins set is four To six millimeters, the upper and lower side of first fins set and the second fins set is in same level.
(3) beneficial effect
The utility model provides a kind of finned tube evaporator, have it is following the utility model has the advantages that
(1) the utility model, since the wind speed and air humidity of fin-tube heat exchanger windward side are far longer than leeward, Windward side fin frosting rate is caused to be far longer than leeward, windward side is stifled full by frost quickly, and big pitch of fins wing is arranged in windward side Piece group increases rate of air circulation, slows down fin frosting;
(2) frosting of conventional finned tube heat exchanger windward side is fast, and refrigerant pressure drop is big, and heat exchange efficiency is low;The utility model subtracts Slow windward side frosting, refrigerant pressure drop is small, and heat exchange efficiency greatly promotes;
(3) the utility model adjusts each branch cold medium flux by setting refrigerant return-air equalizer line, makes each branch refrigerant Equilibrium evaporation, has farthest played the heat exchange area of fin-tube heat exchanger.
Detailed description of the invention
