Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically to a coil condenser. Background Technology

[0002] The coil condenser is a crucial component of a refrigeration system, primarily used to convert high-temperature gaseous refrigerant into a liquid state and remove heat. Its core structure is the coil, typically made of copper or copper-plated steel tubing. Heat exchange is achieved through water spray or air cooling. The coil condenser is a key piece of equipment in the refrigeration system. Its working principle is as follows: when the high-temperature gaseous refrigerant passes through the coil, it exchanges heat with external sprayed water or air, releasing heat. An axial flow fan forces airflow, accelerating the heat dissipation process.

[0003] However, in existing coil condensers, the cooling water evaporates and concentrates on the coil during circulation, easily forming scale mainly composed of calcium bicarbonate, which affects the heat exchange efficiency of the coil. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a coil condenser. The water-cooled section of the coil is initially cooled by a water-cooling box. Since the water-cooled section is completely submerged in the water of the cooling box, the coil is rapidly cooled by water, avoiding scale buildup caused by uneven water distribution and airflow drying. Water is sprayed from above the coil through the water distribution holes in the cooling box, cooling the inner side of the coil through the spray holes in the water distribution plate, and spraying the outer side of the coil through the drain holes in the water collection tank. This achieves multi-angle cooling of the coil, resulting in better cooling performance and preventing scale buildup caused by uneven cooling water distribution and evaporation, further improving the coil's cooling and heat exchange efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coil condenser, including a shell and a coil arranged in a spiral shape inside the shell, wherein a refrigerant is transported in the coil, and the inlet end and outlet end of the coil are both located on the outside of the shell;

[0006] A water collection chamber is provided at the bottom of the housing. A spray assembly for cooling the coil is vertically installed inside the housing. A conveying pipe is provided on the outside of the housing. One end of the conveying pipe is connected to the spray assembly, and the other end of the conveying pipe is connected to the water collection chamber. A conveying pump is provided on the conveying pipe.

[0007] The bottom side of the housing is provided with several air inlets, and the top of the housing is provided with an exhaust fan.

[0008] The spray assembly includes a water-cooled box covering the upper outer side of the coil, a plurality of water distribution plates arranged vertically in an array on the lower inner side of the coil, and a riser pipe connecting the water-cooled box and the water distribution plates. The plurality of water distribution plates are arranged in an array with a plurality of spray holes facing the coil.

[0009] Several of the spray holes are arranged in an arc-shaped array around the water distribution plate with the riser as the center.

[0010] The coil includes a water-cooled section and a mixing section connected to each other. The outer diameter of the water-cooled section is smaller than the outer diameter of the mixing section. The water-cooled box is sleeved on the outside of the water-cooled section, and a plurality of the water distribution trays are arranged on the inside of the mixing section.

[0011] The bottom side of the water-cooled box is provided with several water distribution holes for the mixing section of the cooling coil.

[0012] The inner side of the housing is provided with a plurality of water collection tanks, and the bottom side of the water collection tanks is provided with a plurality of drain holes facing the coil.

[0013] The size of the spray holes in the upper water distribution plate of the spray assembly is smaller than that in the lower water distribution plate.

[0014] A drain pipe is provided on the bottom side of the water collection cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The water-cooled part of the coil is initially cooled by the water-cooled box. Since the water-cooled part is completely immersed in the water in the water-cooled box, the coil is cooled quickly by water, avoiding the scale accumulation caused by uneven water distribution and air drying on the surface of the coil. The coil is cooled by spraying through the water distribution holes of the water-cooled box from above. The inner side of the coil is cooled by spraying through the spray holes of the water distribution plate. The outer side of the coil is cooled by spraying through the drain holes on the water collection tank. Thus, the coil is cooled from multiple angles. Not only is the cooling effect of the coil better, but the scale of the coil caused by uneven distribution of cooling water and evaporation is also avoided, further improving the cooling heat exchange effect of the coil.

[0017] (2) By adjusting and increasing the flow rate of the delivery pump, the water pressure sprayed through the water distribution hole and the spray hole can be adjusted. The larger water pressure is used to flush and clean the outside of the coil, further preventing the accumulation of scale on the coil. A drain pipe is provided at the bottom of the water collection chamber to discharge the scale and debris at the bottom of the water collection chamber and replenish new clean water, thus preventing the accumulation of calcium bicarbonate and further preventing the formation of scale, thereby improving the heat exchange effect of the coil.

Detailed Implementation

[0025] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] See Figures 1-6 A coil condenser includes a housing 1 and a coil 2 arranged in a spiral shape inside the housing 1. Refrigerant is transported in the coil 2, and the inlet and outlet ends of the coil 2 are both located outside the housing 1.

[0027] A water collection chamber 11 is provided at the bottom of the housing 1. A spray assembly 3 for cooling coil 2 is vertically installed inside the housing 1. A conveying pipe 4 is provided on the outside of the housing 1. One end of the conveying pipe 4 is connected to the spray assembly 3, and the other end of the conveying pipe 4 is connected to the water collection chamber 11. A conveying pump 41 is provided on the conveying pipe 4.

[0028] The bottom side of the housing 1 is provided with several air inlets 12, and the top of the housing 1 is provided with an exhaust fan 13.

[0029] The spray assembly 3 includes a water-cooled box 31 covering the upper outer side of the coil 2, several water distribution plates 32 arranged vertically in an array on the lower inner side of the coil 2, and a riser 33 connecting the water-cooled box 31 and the water distribution plates 32. Several spray holes 321 are arranged in an array facing the coil 2 on the several water distribution plates 32.

[0030] Several spray holes 321 are arranged in an arc-shaped array around the water distribution plate 32 with the riser 33 as the center.

[0031] The coil 2 includes a water-cooled section 21 and a mixing section 22 connected to each other. The outer diameter of the water-cooled section 21 is smaller than the outer diameter of the mixing section 22. The water-cooled box 31 is sleeved on the outside of the water-cooled section 21, and a plurality of water distribution trays 32 are arranged in an array on the inside of the mixing section 22.

[0032] Specifically, during operation, the water-cooled box 31 is always filled with water under the pumping action of the transfer pump 41, ensuring that the water-cooled section 21 is submerged.

[0033] The bottom side of the water-cooled box 31 is provided with several water distribution holes 311 for cooling the mixing section 22 in the cooling coil 2.

[0034] The inner side of the housing 1 is provided with a plurality of water collection tanks 14, and the bottom side of the water collection tanks 14 is provided with a plurality of drain holes 141 facing the coil 2.

[0035] The size of the spray hole 321 in the upper water distribution plate 32 of the spray assembly 3 is smaller than the size of the spray hole 321 in the lower water distribution plate 32.

[0036] A drain pipe 15 is provided on the bottom side of the water collection cavity 11.

[0037] The specific working process of this utility model:

[0038] In use, the overheated refrigerant enters the coil 2 through the inlet at the top of the coil 2, and is then cooled by the water-cooled section 21 and the mixing section 22 before being discharged, thus completing the heat exchange process. Specifically, the water-cooled section 21 of the coil 2 is located in the water-cooled box 31. Water is supplied to the water-cooled box 31 through the delivery pipe 4 to initially cool the overheated refrigerant in the water-cooled section 21 of the coil 2. The water-cooled section 21 is completely immersed in the water in the water-cooled box 31, and the refrigerant in the water-cooled section 21 is forcibly cooled by the water. Then, the initially cooled refrigerant enters the mixing section 22.

[0039] Under the continuous pumping action of the delivery pump 41, part of the water in the water-cooled box 31 is discharged through the side water distribution hole 311 to the upper position of the mixing and cooling section 22 to cool the refrigerant in the front section of the mixing and cooling section 22. The other part enters each water distribution plate 32 through the riser 33 and is discharged through the spray hole 321 on the side of the water distribution plate 32. Each layer of spray hole 321 is arc-shaped. The arc-shaped water curtain sprayed from the spray hole 321 is sprayed onto the inner and bottom sides of the mixing and cooling section 22 to further cool the side of the coil 2. After the water sprayed from the spray hole 321 passes through the coil 2, part of it falls from the mixing and cooling section 22 into the water collection chamber 11, and the other part of the water is collected by the water collection tank 14 on the inner side of the shell 1 and discharged again through the water distribution hole 311 on the side of the water collection tank 14 to the outside of the mixing and cooling section 22 of the coil 2 to further cool the coil 2 and fall into the water collection chamber 11.

[0040] The water in the water collection chamber 11 is lifted by the delivery pump 41 and then passes through the delivery pipe 4 to the water cooling box 31 to cool the refrigerant in the water cooling section 21.

[0041] Under the suction of the exhaust fan 13, the outside air passes through the air inlet 12 to cool the coil 2 and water inside the housing 1. Finally, the air is discharged from the top of the housing 1. The air inlet 12 is equipped with slanted louvers, so that the air enters the air inlet obliquely from top to bottom, preventing the falling water from overflowing from the air inlet 12. After that, the refrigerant that has been completely cooled in the coil is discharged from the lower outlet.

[0042] The water-cooled section 21 of the coil 2 is initially cooled by the water-cooled box 31. Since the water-cooled section 21 is completely immersed in the water in the water-cooled box 31, the coil 2 is rapidly cooled by water, avoiding scale buildup caused by uneven water distribution and air drying on the surface of the coil 2. The coil 2 is cooled by spraying water from above through the water distribution holes 311 of the water-cooled box 31, the inner side of the coil 2 is cooled by spraying water through the spray holes 321 of the water distribution plate 32, and the outer side of the coil 2 is cooled by spraying water through the drain holes 141 on the water collection tank 14. This achieves multi-angle cooling of the coil 2, which not only improves the cooling effect of the coil 2, but also avoids scale buildup on the coil 2 caused by uneven cooling water distribution and evaporation, further improving the cooling and heat exchange effect of the coil 2.

[0043] By adjusting and increasing the flow rate of the delivery pump 41, the water pressure sprayed through the water distribution hole 311 and the spray hole 321 can be adjusted. The larger water pressure flushes and cleans the outside of the coil 2, further preventing scale from accumulating on the coil 2. A drain pipe 15 is provided on the bottom side of the water collection chamber 11 to discharge the scale and debris at the bottom of the water collection chamber 11 and replenish it with new clean water, thus preventing the accumulation of calcium bicarbonate and further preventing scale formation, thereby improving the heat exchange effect of the coil 2.

Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
