Description
Technical Field
The utility model relates to a refrigeration technology's field, concretely relates to compound source type does not have cold bridge fin type heat exchanger.
Background
The air-cooled water chilling unit is a cold water type unit which takes air as a cold source and water as a heat transfer medium. The air-cooled water chilling unit with the natural cooling water coil pipe can effectively improve the annual comprehensive energy efficiency ratio of the unit, can automatically stop the operation of a compressor in a low-temperature environment, and directly utilizes the outdoor low-temperature environment temperature to cool air-conditioning water at a user side through the outdoor water coil pipe.
The air-cooled water chilling unit with natural cooling water coil pipe, air-cooled heat exchanger is made up of natural cooling water coil pipe and refrigerant condensation coil pipe. In order to make the unit compact and beautiful, the natural cooling water coil and the refrigerant condensing coil are usually designed into an integral structure. If the fins of the natural cooling water coil pipe and the fins of the refrigerant condensing coil pipe are the same fins, when the unit works in a compressor refrigeration and natural cooling mixed mode, low-temperature chilled water in the water coil pipe and high-temperature refrigerant in the refrigerant side coil pipe form a cold bridge through the fins to carry out heat exchange, so that the heat exchange effect of the water coil pipe is reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a compound source type does not have cold bridge fin type heat exchanger.
The purpose of the utility model is accomplished through following technical scheme: the composite source type cold-bridge-free finned heat exchanger mainly comprises a refrigerant condensing coil copper pipe, a natural cooling water coil copper pipe, an end plate, a refrigerant condensing coil fin and a natural cooling water coil fin, wherein the refrigerant condensing coil fin and the natural cooling water coil fin which are independently punched are arranged in the end plate, fin intervals are arranged between the refrigerant condensing coil fin and the natural cooling water coil fin, three rows of refrigerant condensing coil copper pipes are arranged on the refrigerant condensing coil fin at equal intervals, two rows of natural cooling water coil copper pipes are arranged on the natural cooling water coil fin at equal intervals, the end plate is provided with stretching holes, and the direction of the stretching holes is consistent with the directions of the refrigerant condensing coil copper pipes and the natural cooling water coil copper pipes.
The refrigerant condensing coil copper pipe adopts an internal thread copper pipe, and the natural cooling water coil copper pipe adopts a light pipe.
The utility model has the advantages that: the structure is compact and beautiful, when the unit works in a mixed mode, the refrigerant coil cools the refrigerant, and the water coil cools water naturally, so that the temperature of the water entering the evaporator is reduced, the power of the compressor is reduced, and the energy efficiency is improved.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawing, the composite source type cold bridge-free finned heat exchanger mainly comprises a refrigerant condensing coil copper pipe 1, a natural cooling water coil copper pipe 2, an end plate 3, refrigerant condensing coil fins 4 and natural cooling water coil fins 5, wherein the refrigerant condensing coil fins 4 and the natural cooling water coil fins 5 which are independently punched are arranged in the end plate 3, fin intervals 6 are arranged between the refrigerant condensing coil copper pipes and the end plate 3, three rows of refrigerant condensing coil copper pipes 1 are arranged on the refrigerant condensing coil fins 4 at equal intervals, two rows of natural cooling water coil copper pipes 2 are arranged on the natural cooling water coil fins 5 at equal intervals, the end plate 3 is provided with a stretching hole, the direction of the stretching hole is consistent with the directions of the refrigerant condensing coil copper pipes 1 and the natural cooling water coil copper pipes 2, and the copper pipes are prevented from being scratched by burrs in the end plate.
The refrigerant condenser coil copper pipe 1 is an internal thread copper pipe, so that the contact area of a heat exchange pipe is increased, the heat exchange efficiency is improved, and the natural cooling water coil copper pipe 2 is a light pipe, so that the reduction of the heat exchange effect caused by the fact that scales are easy to adhere to the internal thread pipe is avoided.
The utility model discloses compact structure, pleasing to the eye, unit mixed mode during operation, refrigerant coil cooling refrigerant, natural cooling water coil cooling water make the temperature that gets into the evaporimeter reduce, reduce compressor power, improve the efficiency.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
