Description

Technical Field

[0001] The utility model relates to the field of copper tube fluorine floor heating, in particular to a shunt distribution integrated component. Background Art

[0002] As people's living standards improve, air conditioning heating has the disadvantages of limited heating performance and easy drying of indoor air. Therefore, most people now use floor heating in winter. Copper tube fluorine floor heating has the characteristics of good thermal conductivity and fast temperature rise, which is popular among people.

[0003] The existing copper tube fluorine floor heating special refrigerant diverter is connected to the air outlet and liquid return port of the heating host through two refrigerant distribution units. The air inlet pipe and liquid return pipe are welded to the refrigerant distribution unit respectively to perform diversion and recovery.

[0004] However, in the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application discovered that the above technology has at least the following technical problems:

[0005] The air intake pipe and the liquid return pipe are welded to the distributor distribution unit. Since the air intake pipe and the liquid return pipe are usually dozens or hundreds of meters long, once they are blocked, it is difficult to determine the blockage point, and the entire diverter will be scrapped, causing huge losses.

[0017] The embodiment of the present application solves the problem in the prior art that the entire component becomes scrapped once blocked by providing a diversion and distribution integrated component.

[0018] The technical solution in the embodiment of the present application is to solve the above-mentioned problem of overall scrapping, and the overall idea is as follows:

[0019] By setting up a section of connecting pipe to weld the through hole of the manifold first, since clogging is easy to occur during welding, the circulation pipe is not welded first. The flow and tightness test of the manifold with the connecting pipe welded is carried out first. After the test is passed, the circulation pipe is welded to the connecting pipe. This ensures that only qualified manifolds are used, avoiding the scrapping of dozens or hundreds of meters of circulation pipes, greatly saving costs. In order to avoid clogging when welding the circulation pipe and the connecting pipe, a flared section is set on the circulation pipe. After the connecting pipe is inserted into the flared section, welding is performed on the outside of the flared section to avoid solder and impurities clogging the connecting pipe and the circulation pipe.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example

[0022] A diversion setting allocates integrated components, such as Figure 1-3 As shown, the diverter plate 1 includes a distribution plate 1, which serves as a distribution component and has the function of dividing a single channel into multiple channels for diverting refrigerant gas or liquid. Along the direction of refrigerant flow, one end is provided with an opening 101 connected to the cavity for connecting to a pipe for transporting refrigerant, and the other end is provided with multiple through holes 102;

[0023] A plurality of connecting pipes 2, the number of the connecting pipes 2 being the same as the number of the through holes 102, and the connecting pipes 2 being welded to the through holes 102;

[0024] A plurality of circulation pipes 3 , the number of the circulation pipes 3 being consistent with the number of the through holes 102 , and the circulation pipes 3 and the corresponding connecting pipes 2 being welded.

[0025] Specifically, the compressor transports high-temperature and high-pressure refrigerant gas to the opening 1 through the outlet pipe and enters the cavity of the diverter plate 1. The end of the diverter plate 1 away from the opening 1 along the direction of refrigerant gas transportation has a flat end face with multiple rows and columns of through holes evenly arranged. Since the end face is flat, the through holes only need to be chamfered to reduce clogging of the welding joints.

[0026] The connecting pipe 2 is a capillary copper tube with a length of 1-5 cm. After the connecting pipe 2 and the through hole 102 are welded, the welded components are tested for refrigerant gas or liquid circulation and tightness: if the test fails, the problem can be discovered in time, and the failure at the connection between the diverter plate 1 and the connecting pipe 2 can be effectively prevented. It is convenient to test whether the pipeline at the welding point of the diverter plate 1 is unobstructed, and effectively solve the problem of unsmooth pipeline connection caused by welding the diverter plate 1 to other pipelines; it can be connected to the circulation pipe 3 only after passing the test to avoid the circulation pipe 3 being scrapped due to unqualified welding quality of the connecting pipe 2 and the through hole 102. The circulation pipe 3 is a capillary copper tube, usually tens of meters or even hundreds of meters long, used to coil around the indoor floor. Different lengths and shapes can be set according to the space in the house to heat the room and keep the room warm.

[0027] Since it is also necessary to connect to the refrigerant return port of the compressor, the diverter plate 1 and the connecting pipe 2 welding assembly of this embodiment are two sets, connecting the two ends of the circulation pipe 3, and the opening 1 is also connected to the pipe connected to the refrigerant return port. When the refrigerant gas in the circulation pipe 3 releases heat, it will condense into liquid and flow back to the compressor through the through hole 102 of the diverter plate 1.

[0028] The circulation pipe 3 has a flared end, and the flared end of the circulation pipe 3 is inserted into the connecting pipe 2 for welding, which will not block the welding point and effectively improve the connectivity between the pipes.

[0029] Working principle: When in use, the diverter plate 1 is first welded to the connecting pipe 2, and the welded components are individually tested for circulation and tightness. The components that pass the test can be subsequently welded to the two ends of the circulation pipe 3, and the openings 101 of the diverter plate 1 at both ends are respectively connected to the air outlet pipe and return liquid pipe of the compressor to form a closed loop of refrigerant heat transfer.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0031] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
