Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled coolers, in particular to a water-cooled cooler for an ultra-low temperature capture pump. Background Art

[0002] The combination of ultra-low temperature capture pump and water-cooled chiller can effectively capture and recycle low-temperature water vapor. The water-cooled chiller quickly captures the residual gas in the vacuum system through the surface low-temperature condensation effect. The water-cooled chiller of the ultra-low temperature capture pump is mainly used to cool the refrigerant. This cooler uses liquid refrigerant (such as water) to absorb and transfer heat, thereby reducing the temperature of the refrigerant. In an ultra-low temperature environment, this cooling method is very important for maintaining the low temperature state of the refrigerant and keeping the equipment running normally.

[0003] Existing water-cooled coolers usually use coolant to flow through the outer wall of the heat exchange tube to dissipate heat and exchange heat with the heat medium in the pipe. This method can reduce the influence of flow and pressure on the heat exchange effect and facilitate cleaning and maintenance. However, the cooling efficiency of the coolant outside the tube is relatively low and heat loss is prone to occur. Therefore, we need to propose a water-cooled cooler for ultra-low temperature capture pumps. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can inject the refrigerant that needs to be cooled down into the interior of the outer tube body through the refrigerant inlet pipe by arranging the outer tube body, the refrigerant inlet pipe and the refrigerant outlet pipe for coordinated use.

The opposite ends of the two groups of straight tubes 201 are fixedly connected with spiral heat exchange tubes 202. Fins can be provided on the outer wall of the spiral heat exchange tubes 202 to increase the contact area with the refrigerant, which is beneficial to improve the heat exchange effect.

[0025] The spiral heat exchange tube 202 is located inside the outer tube body 1. The material of the outer tube body 1 is set to be made of stainless steel. The materials of the straight tube 201 and the spiral heat exchange tube 202 are both set to be made of copper. By setting the straight tube 201 and the spiral heat exchange tube 202 for coordinated use, the coolant can flow through one group of the straight tubes 201 through the inside of the spiral heat exchange tube 202, and then be discharged from the other group of the straight tubes 201. The spiral heat exchange tube 202 can absorb the heat in the refrigerant, and then the coolant inside the spiral heat exchange tube 202 takes away the heat, thereby achieving the effect of cooling the refrigerant.

[0026] The heat dissipation component 3 includes a heat exchange plate 301, which is fixedly mounted on the inner wall of the outer tube body 1. A plurality of groups of heat dissipation fins 302 are fixedly mounted at equal intervals on one side wall of the heat exchange plate 301.

By arranging the heat exchange plate 301 and the heat dissipation fins 302 for coordinated use, part of the heat in the refrigerant can be absorbed by the heat exchange plate 301, and then transferred to the surface of the heat dissipation fins 302, and finally dissipated to the outside air, which is conducive to further improving the cooling efficiency of the refrigerant.

[0027] The outer wall of the outer tube body 1 is provided with a plurality of groups of through slots 7 which are equidistantly arranged to match the heat dissipation fins 302, and the heat dissipation fins 302 are fixedly embedded in the through slots 7;
