Description

Technical Field

[0001] This utility model relates to the field of spiral tube condenser technology, and in particular to a spiral tube condenser for use in refrigeration and air conditioning systems. Background Technology

[0002] The working principle of a condenser is mainly to use air or other media as a cooling medium to transfer heat from the refrigerant or heat carrier inside the condenser to the cooling medium, thereby cooling down the heat carrier.

[0003] Most existing condensers use straight tubes, resulting in a short travel distance for the heat carrier within the condenser and thus a relatively poor heat dissipation effect. To enhance the condensing effect, the length or number of condenser tubes is usually increased. However, this increases the size of the condenser and affects its installation.

[0004] Therefore, this application provides a spiral tube condenser for refrigeration and air conditioning systems to overcome the deficiencies of the prior art. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the heat dissipation effect of existing condensers is relatively poor.

[0006] This utility model provides a spiral tube condenser for a refrigeration and air conditioning system, comprising a housing 1, a housing 2 connected to the top flange of the housing 1, and a housing 3 connected to the bottom flange. A cold medium inlet is fixedly connected to the upper left part of the housing 1, and a cold medium outlet is fixedly connected to the lower right part. A hot medium inlet is fixedly connected to the end of the housing 2 away from the housing 1, and a hot medium outlet is fixedly connected to the end of the housing 3 away from the housing 1. Two opposing connecting plates are installed in the housing 1, and at least one condensation layer is installed between the two connecting plates. Each condensation layer includes at least one condenser tube.

[0007] As a preferred technical solution, the connecting plate is provided with a plurality of connecting holes, which are evenly distributed around the center of the connecting plate. Each connecting hole is equipped with a condenser tube, and multiple condenser tubes together form a condensation layer. The connecting plate is welded to the condenser tubes to prevent the condenser tubes from loosening and affecting the condensation work, which could cause the machine to malfunction.

[0008] As a preferred technical solution, one of the two connecting plates is located above and the other is located below. Several connecting holes are also provided on the connecting plates. The connecting holes are evenly distributed around the center of the connecting plate. The connecting holes are located inside the connecting holes. Each connecting hole is equipped with a condenser tube. Multiple condenser tubes together form a condensation layer.

[0009] As a preferred technical solution, the condenser includes a first connecting pipe, the bottom of which is fixedly connected to a second connecting pipe, and the bottom of which is fixedly connected to a third connecting pipe. Both the first and third connecting pipes are hollow straight pipes, while the second connecting pipe is a hollow spiral pipe. Without changing the size of the condenser, the travel distance of the heat medium in the condenser and the cooling time in the condenser are increased, thereby improving the condensation effect. The first connecting pipe is fixedly connected to the upper connecting plate, and the third connecting pipe is fixedly connected to the lower connecting plate. The first connecting pipe is connected to the heat medium inlet, and the third connecting pipe is connected to the heat medium outlet.

[0010] As a preferred technical solution, at least two heat dissipation plates are installed on the condenser tube, and the two heat dissipation plates are located between the two connecting plates. At least one heat dissipation plate is installed on the first connecting pipe, and at least one heat dissipation plate is installed on the third connecting pipe. The heat dissipation plate has several connection holes three and several connection holes four, and the condenser tube is installed in the connection holes three and four. The heat dissipation plate also has several water permeable holes, and water can enter the area between the heat dissipation plate and the connecting plate through the water permeable holes, which facilitates sufficient heat dissipation and condensation of the condenser tube. The heat dissipation plate is made of aluminum, which is lightweight and has good heat dissipation effect.

[0011] The beneficial effects of the spiral tube condenser for refrigeration and air conditioning systems provided by this utility model are:

[0012] This invention, by setting up a condenser tube consisting of two straight tubes and one spiral tube, can increase the travel distance of the heat medium in the condenser tube and the cooling time in the condenser without increasing the number of condenser tubes or changing the size of the condenser, thereby improving the condensation effect. At the same time, the number of condenser tubes can also be changed according to specific needs.

[0013] By installing a heat sink on the condenser tube, the heat dissipation efficiency can be further improved. Attached Figure Description

The condensation layer includes at least one condenser tube 10.

[0023] like Figures 2 to 3 As shown: The connecting plate 8 has a plurality of connecting holes 81, which are evenly distributed around the center of the connecting plate 8. Each connecting hole 81 is equipped with a condenser tube 10. The condenser tubes 10 in the multiple connecting holes 81 together form a condensation layer. The connecting plate 8 is welded to the condenser tubes 10 to prevent the condenser tubes 10 from loosening and affecting the condensation work, causing the machine to malfunction.

[0024] Two connecting plates 8 are positioned, one above the other. Each connecting plate 8 has several connecting holes 82, which are evenly distributed around the center of the connecting plate 8. The connecting holes 82 are located inside the connecting holes 81. Each connecting hole 82 has a condenser tube 10 installed in it. The condenser tubes 10 in the multiple connecting holes 82 together form a condensation layer. This product has two condensation layers, but one or more condensation layers can be set according to the specific needs of the customer.

[0025] like Figures 2 to 5 As shown: The condenser tube 10 includes a first connecting tube 101, the bottom of which is fixedly connected to a second connecting tube 102, and the bottom of the second connecting tube 102 is fixedly connected to a third connecting tube 103. Both the first connecting tube 101 and the third connecting tube 103 are hollow straight tubes, while the second connecting tube 102 is a hollow spiral tube. Without changing the size of the condenser, the travel distance of the heat medium in the condenser tube 10 and the cooling time in the condenser are increased, thereby improving the condensation effect. The first connecting tube 101 is fixedly connected to the upper connecting plate 8, and the third connecting tube 103 is fixedly connected to the lower connecting plate 8. The first connecting tube 101 is connected to the heat medium inlet 6, and the third connecting tube 103 is connected to the heat medium outlet 7.

The heat dissipation plate 9 is made of aluminum, which is lightweight and has good heat dissipation effect.

[0027] Operating principle: A cold medium (e.g., water) is injected into the condenser through the cold medium inlet 4, and a hot medium (steam or other substances that need to be cooled) enters the condenser through the hot medium inlet 6. The cold medium cools the wall of the condenser tube 10, and the hot medium is cooled and condensed in the condenser tube 10. Finally, it flows out from the hot medium outlet 7, and the cold medium absorbs heat and flows out from the cold medium outlet 5.
