Description

Technical Field

[0001] This utility model relates to the field of compressor heat exchanger technology, specifically a spiral flat tube compressor heat exchanger with self-cleaning function. Background Technology

[0002] A compressor is a driven fluid machine that raises refrigerant gas to a high pressure. It is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it by driving a piston through the motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. A heat exchanger is needed when the compressor is working. The heat exchanger is a device that transfers the heat generated by the compressor to the surrounding environment.

[0003] Chinese patent discloses a spiral blade tube heat exchanger (authorization announcement number CN202582348U). This patented technology utilizes the connection between continuous spiral blades and the inner wall of the shell to form a continuous spiral liquid channel. The liquid flows smoothly and quickly, but can also provide a longer flow path, which can improve heat exchange efficiency. At the same time, this structure has a small liquid pressure loss, and the manufacturing process is simple, which can reduce costs.

[0004] However, most existing heat exchangers lack a self-cleaning mechanism, leading to scale buildup on the exterior of the heat exchange tubes during heat exchange, thus reducing their lifespan. As seen in the aforementioned prior art, it lacks a cleaning mechanism. In practical applications, when the compressor heat exchanger is in operation, scale easily forms inside the heat exchanger tubes, which can significantly shorten its lifespan if not cleaned regularly. Therefore, those skilled in the art have provided a spiral flat tube compressor heat exchanger with a self-cleaning function to address the problems mentioned in the background section. Utility Model Content

The interior of the heat exchanger body is provided with a spiral flat tube communicating with the second inlet and the second outlet. A spray pipe is provided on the upper surface of the heat exchanger body near the second inlet. The lower end of the spray pipe is connected to a liquid outlet pipe inside the heat exchanger body. Spray nozzles are provided on the outer surface and the lower surface of the liquid outlet pipe. Filter screens are also symmetrically arranged inside the spray pipe.

[0007] An installation sleeve is installed on the outside of the heat exchanger body. A connecting seat is connected to the lower surface of the installation sleeve. A lifting plate is fixed to the lower surface of the connecting seat. A base plate is provided below the lifting plate. A cylinder is provided on the upper surface of the base plate below the lifting plate.

[0008] Preferably, four guide rods are symmetrically arranged on the upper surface of the base plate, and the upper ends of the guide rods penetrate the upper surface of the lifting plate.

[0009] Preferably, the fixed end of the cylinder is installed at the middle position of the upper surface of the base plate, and the telescopic end of the cylinder is connected at the middle position of the lower surface of the lifting plate.

[0010] Preferably, two sets of filters are symmetrically arranged inside the spray pipe, and the distance between the two sets of filters is 10cm.

[0011] Preferably, at least ten nozzles are symmetrically arranged on the lower surface of the liquid outlet pipe, and at least eight nozzles are symmetrically arranged on the outer surface of the liquid outlet pipe.

[0012] Preferably, the mounting sleeve is bolted to the outside of the heat exchanger body, and the connecting seat is mounted at the middle position on the upper surface of the lifting plate.

[0013] Beneficial effects

[0014] This invention provides a spiral flat tube compressor heat exchanger with self-cleaning function. Compared with the prior art, it has the following advantages:

[0015] 1. This self-cleaning spiral flat tube compressor heat exchanger, through the arrangement of spray pipes, filters, liquid outlet pipes and nozzles, allows external water to pass through the filter screen into the liquid outlet pipe and finally be sprayed out through the nozzles. This achieves the purpose of self-cleaning the interior of the heat exchanger body, avoiding external contamination of the spiral flat tubes and affecting their service life, thus demonstrating good practicality.

[0016] 2. This self-cleaning spiral flat tube compressor heat exchanger, through the arrangement of a connecting seat, lifting plate, base plate, mounting sleeve, guide rod, and cylinder, utilizes the operation of the cylinder to guide the lifting plate to rise and fall outside the four guide rods, thereby enabling the heat exchanger body connected to the connecting seat via the mounting sleeve to rise and fall, so as to realize the use of the heat exchanger body at different heights, which is practical.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a spiral flat tube compressor heat exchanger with self-cleaning function, including a heat exchanger body 1, a first inlet 11 and a first outlet 12 arranged from left to right on both sides of the heat exchanger body 1, and a second inlet 13 and a second outlet 14 arranged from left to right on the upper surface of the heat exchanger body 1. The interior of the heat exchanger body 1 is provided with a spiral flat tube 15 communicating with the second inlet 13 and the second outlet 14. A spray pipe 2 is arranged on the upper surface of the heat exchanger body 1 near the second inlet 13. The lower end of the spray pipe 2 is connected to a liquid outlet pipe 22 inside the heat exchanger body 1. The outer surface and the lower surface of the liquid outlet pipe 22 are provided with nozzles 23. The interior of the spray pipe 2 is also symmetrically provided with filter screens 21. This arrangement can achieve efficient heat exchange using the spiral flat tube 15, and the external water can be sprayed out through the nozzles 23 outside the spray pipe 2 to clean the spiral flat tube 15. It has good practicality.

[0023] An installation sleeve 33 is installed on the outside of the heat exchanger body 1. A connecting seat 3 is connected to the lower surface of the installation sleeve 33. A lifting plate 31 is fixed to the lower surface of the connecting seat 3. A base plate 32 is provided below the lifting plate 31. A cylinder 35 is provided on the upper surface of the base plate 32 below the lifting plate 31. This arrangement uses the operation of the cylinder 35 to make the lifting plate 31 rise and fall, thereby adjusting the height of the heat exchanger body 1, so that the heat exchanger body 1 can be used at different heights.

[0024] exist Figure 3 In the middle: Four guide rods 34 are symmetrically arranged on the upper surface of the base plate 32. The upper end of the guide rods 34 penetrates the upper surface of the lifting plate 31. This arrangement uses four guide rods 34 to make the lifting plate 31 stable during lifting and lowering, so as to facilitate its height adjustment.

[0025] exist Figure 3 In the middle: the fixed end of the cylinder 35 is installed at the middle position of the upper surface of the base plate 32, and the telescopic end of the cylinder 35 is connected to the middle position of the lower surface of the lifting plate 31. This setting uses the operation of the cylinder 35 to make the lifting plate 31 rise and fall, thereby adjusting the height of the heat exchanger body 1, so that the heat exchanger body 1 can be used at different heights.

[0026] exist Figure 2 In the middle: two sets of filter screens 21 are symmetrically arranged inside the spray pipe 2, and the distance between the two sets of filter screens 21 is 10cm. At least ten spray heads 23 are symmetrically arranged on the lower surface of the liquid outlet pipe 22, and at least eight spray heads 23 are symmetrically arranged on the outer surface of the liquid outlet pipe 22. This arrangement uses the filter screens 21 to filter the cleaning water entering the spray pipe 2, thereby avoiding the spray heads 23 from becoming clogged and affecting the cleaning work.

[0027] exist Figure 1 and Figure 3 In the middle: the mounting sleeve 33 is installed on the outside of the heat exchanger body 1 by bolts, and the connecting seat 3 is installed at the middle position on the upper surface of the lifting plate 31. This setting allows the mounting sleeve 33 to be installed on the outside of the heat exchanger body 1 by bolts, thereby achieving the purpose of subsequent height adjustment of the heat exchanger body 1.

[0028] When the self-cleaning spiral flat tube compressor heat exchanger is working (or in use), the spray pipe 2 is first connected to the external cleaning water pipe. The external water pump can bring the cleaning water into the spray pipe 2 through the water pipe. The filter screen 21 inside the spray pipe 2 can perform double filtration on the incoming water. After filtration, the water will be sprayed out through the nozzle 23 outside the liquid outlet pipe 22. This can achieve the purpose of self-cleaning the spiral flat tube 15. The cleaned debris can be discharged outward by opening the slag outlet 16.

[0029] Meanwhile, when the heat exchanger body 1 is in use, the cylinder 35 on the base plate 32 can be started to work, which will cause the lifting plate 31 to rise and fall on the base plate 32. That is, the lifting plate 31 moves under the guidance of the guide rod 34, thereby achieving the purpose of adjusting the height of the heat exchanger body 1. In this way, the heat exchanger body 1 can be used at different heights, which is practical.
