Description

Coil condenser structure

Technical Field

The utility model relates to the field of condensers, in particular to a coil condenser structure.

Background

The condenser is a common device of an air conditioning system, is used for introducing high-temperature refrigerant, and exchanges heat with the outside to reduce the temperature of the refrigerant, and finally the condenser pipe outputs low-temperature refrigerant. In order to have higher heat exchange efficiency, a coil of an existing condenser is usually matched with radiating fins which are arranged side by side, the coil of the condenser penetrates through the radiating fins, a fan sucks air from one surface of the condenser, the air is sucked away by the fan after passing through the condenser from the other surface of the condenser, the air exchanges heat with a refrigerant through the radiating fins and the wall of the coil when passing through the condenser, and the heat of the refrigerant is taken away by the sucked air. The finned condenser in the prior art is generally of a plane plate type structure, occupies a large space and has the problem of low heat exchange efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a coil condenser structure to solve the problems of large occupied space and low heat exchange efficiency of a fin condenser in the prior art.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a coil condenser structure, includes radiator and coil pipe, the radiator includes that inner tube, urceolus and closing cap connect in the end cover of inner tube, urceolus axial correspondence end, the coil pipe is arranged in between inner tube, the urceolus and is coiled in the inner tube surface, and the inner tube lateral wall is equipped with inside, the urceolus of a plurality of openings with intercommunication inner tube, and the urceolus lateral wall is equipped with a plurality of through-holes, and every end cover is equipped with the air vent with the inside intercommunication of inner tube respectively, and one of them end cover surface corresponds the air vent position and installs the fan, the air intake of fan is through corresponding air vent and the inside intercommunication of inner tube.

When high-temperature refrigerant is introduced into the coil pipe, the coil pipe and the radiator form heat exchange, the heat is radiated outwards through the radiator, meanwhile, the fan is started, a part of air flows into the inner cylinder from a vent hole of an end cover without the fan, and the air is sucked by the fan to flow out after the heat exchange between the inner cylinder and the coil pipe so as to take away heat; the other part of air flows into the outer barrel from the through hole in the side wall of the outer barrel, flows through the coil pipe and then enters the inner barrel from the opening of the inner barrel, the air exchanges heat with the outer barrel, the coil pipe and the inner barrel respectively in the flowing process, and finally the air is sucked by the fan and flows out to take away heat.

The utility model can be vertically used, and the air flowing in the vertical direction has upward diffusion movement because heat is absorbed to form hot air, so that the air after heat absorption can be more quickly taken away by the fan by utilizing the hot air floating principle.

Compared with the prior art, the heat exchanger has a three-dimensional structure, occupies a small space and has high heat exchange efficiency.

Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

As shown in fig. 1 and 2, the coiled tube condenser structure of the utility model comprises a heat sink and a coiled tube 1, wherein the heat sink is made of copper material, the heat sink structurally comprises an inner cylinder 2 which is vertical in the axial direction and an outer cylinder 3 which is coaxially sleeved outside the inner cylinder, the heights of the inner cylinder 2 and the outer cylinder 3 are the same, the upper end and the lower end of a double-cylinder structure consisting of the inner cylinder 2 and the outer cylinder 3 are respectively covered and fixedly connected into a whole with an end cover 4, wherein the center of the upper end cover is provided with a vent hole which is used as an outlet, the vent hole is communicated with the inside of the inner cylinder 2, the top surface of the upper end cover is provided with a fan 5, and the inlet of the fan 5 is communicated with the inside of the inner cylinder 2 through the outlet. The lower end cover is provided with a vent hole as an inlet 6, the vent hole as the inlet 6 is communicated with the inside of the inner cylinder 2, and the vent hole as the inlet 6 is communicated with the outside for the external air to enter.

The lateral wall of inner tube 2 is equipped with the rectangular opening 7 of multichannel along axial extension respectively, and 7 annular evenly distributed of the rectangular opening of multichannel, the height of the rectangular opening 7 of every way and inner tube 2 highly uniform.

The coil pipe 1 is arranged between the inner cylinder 2 and the outer cylinder 3, the coil pipe 1 is tightly wound on the outer wall of the inner cylinder 2 in a plurality of circles, and the inner wall of the outer cylinder 3 is contacted with the coil pipe 1. Two ends of the coil 1 respectively penetrate out of the outer cylinder 3 to form a pipe orifice 8 for connecting a compressor and an evaporator of an air conditioning system.

The side wall of the outer cylinder 3 is provided with a plurality of through holes 9, one end of each through hole 9 is communicated to the inside of the outer cylinder 3, and the other end of each through hole 9 is respectively communicated to the outside. A plurality of heat dissipation fins 10 are fixed to the outer wall of the outer cylinder 3.

When high-temperature refrigerant is introduced into the coil 1, the heat can be dissipated outwards through the outer cylinder 3 and the heat dissipation fins 10 connected with the outer cylinder, and can be dissipated into the inner cylinder through the inner cylinder 2. Meanwhile, the fan 5 works to suck air, part of the air enters the inner cylinder 2 from the inlet 6, contacts with the inner wall of the inner cylinder 2 to form heat exchange, and is taken away by the fan 5; and part of air enters the outer cylinder 3 from the through hole 9, then enters the inner cylinder 2 from the side opening 7 of the inner cylinder 2 after passing through the outer walls of the coil pipe 1 and the inner cylinder 2, and is finally sucked and taken away by the fan 5, and the part of air contacts the outer cylinder 3, the coil pipe 1 and the inner cylinder 2 to form heat exchange.
