Description

Technical Field

[0001] The present application relates to the technical field of heat transfer equipment, and in particular to an antifreeze surface cooler with gravity flow and clean discharge. Background Art

[0002] A surface cooler, also known as a surface cooler, consists of several metal pipes. Their principle is to allow a heat medium, a coolant, or a heat-conducting medium to flow through the inner cavity of the metal pipes. The gas to be processed then flows through these metal pipes, where it comes into contact with the metal pipes during the flow, exchanging heat to achieve the purpose of heating or cooling the gas. Conventional surface coolers have the metal pipes arranged horizontally on a rack. While this ensures the flow of the heat-conducting medium, the rack utilization rate is poor. Furthermore, when the surface cooler is used or shut down, the heat-conducting medium easily accumulates in the metal pipes. This is especially true in winter, when the heat-conducting medium easily freezes, limiting the function of the surface cooler or even damaging it. Manual removal of the heat-conducting medium from the metal pipes is required after each use, which is cumbersome and difficult to ensure. Utility Model Content

[0005] Furthermore, the heat exchange pipe includes a first heat exchange branch and a second heat exchange branch that pass through the frame, and the first heat exchange branch is located below the second heat exchange branch away from the air intake side; the first heat exchange branch and the second heat exchange branch are connected to a coil elbow, and the coil elbow is set at an angle.

However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features.

[0026] Reference Figure 1 、 Figure 2 as well as Figure 3 A self-flowing, clean-draining antifreeze surface cooler includes a frame 1, a heat exchange structure 2, a liquid inlet structure 3, and a liquid outlet structure 4 disposed on the frame 1. During operation, a heat transfer medium enters the heat exchange structure 2 through the liquid inlet structure 3. As the heat transfer medium flows through the heat exchange structure 2, the gas exchanges heat through the heat exchange structure 2, and then the heat transfer medium flows out of the liquid outlet structure 4.

[0027] Specifically, the rack 1 is used to support various mechanisms. The top and bottom of the rack 1 are closed. The rack 1 has an air inlet side 11 and an air outlet side 12. The heat exchange structure 2 is arranged between the air inlet side 11 and the air outlet side 12. The liquid inlet structure 3 and the liquid outlet structure 4 are arranged on the side of the rack 1 that is different from the air inlet side 11 and the air outlet side 12.

[0028] Heat exchange structure 2 includes several heat exchange assemblies 21. In this embodiment, to increase the contact area between heat exchange assemblies 21 and the gas and improve the efficiency of the cooler, heat exchange assemblies 21 are evenly arranged along the width of one side of rack 1. This arrangement allows heat exchange assemblies 21 to fully fill rack 1, effectively reducing empty space in the cooler and avoiding problems such as poor heat exchange at the top and bottom of the cooler, uneven air outlet temperatures, and uneven gas flow rates.

[0029] The heat exchange assembly 21 includes a plurality of heat exchange tubes 211 arranged along the length of one side of the rack 1. The heat exchange tubes 211 are inclined from the air inlet side 11 to the air outlet side 12. More specifically, the heat exchange tubes 211 include a first heat exchange branch 2111 and a second heat exchange branch 2112, which are arranged through the rack 1. The first heat exchange branch 2111 is located below the second heat exchange branch 2112, away from the air inlet side 11. The first heat exchange branch 2111 and the second heat exchange branch 2112 are connected by a coil elbow 2113. The coil elbow 2113 is arranged at an angle.

[0030] At the same time, the liquid inlet structure 3 is arranged on the air outlet side 12 and is connected to the heat exchange assembly 21, and the liquid outlet structure 4 is arranged on the air inlet side 11 and is connected to the heat exchange assembly 21. The liquid inlet structure 3 includes a liquid inlet main pipe 31 and a plurality of liquid inlet vertical branches 32 arranged on one side of the rack 1. The liquid inlet main pipe 31 has a liquid inlet and is connected to the plurality of liquid inlet vertical branches 32. The liquid inlet vertical branches 32 are connected to the heat exchange assembly 21. In this embodiment, the liquid inlet vertical branches 32 pass through the rack 1 and are connected to the heat exchange tubes 211 near the air outlet side 12. In order to ensure heat exchange efficiency and liquid inlet efficiency, the plurality of liquid inlet vertical branches 32 are evenly arranged along the length direction of one side of the rack 1. The number of the plurality of liquid inlet vertical branches 32 is the same as the number of heat exchange tubes 211 included in the heat exchange assembly 21 near the air outlet side 12 of the rack 1, and the heights correspond one to one.

[0031] To further improve the liquid inlet efficiency, the liquid inlet structure 3 also includes a lower liquid inlet assembly 33, which includes a lower branch pipe 331 connected to the liquid inlet main pipe 31. The lower branch pipe 331 is located below the rack 1 and is horizontally arranged. The lower branch pipe 331 is connected to a plurality of lower liquid inlet branch pipes 332, and the plurality of lower liquid inlet branch pipes 332 are connected to the heat exchange assembly 21. In this embodiment, the lower liquid inlet branch pipes 332 pass through the rack 1 and are connected to the heat exchange pipe 211 at the bottom of the rack 1. Similarly, the liquid outlet structure 4 includes a liquid outlet main pipe 41 and a plurality of liquid outlet vertical branches 42 arranged on one side of the rack 1. The liquid outlet main pipe 41 has a liquid outlet and is connected to the plurality of liquid outlet vertical branches 42. The liquid outlet vertical branches 42 are connected to the heat exchange assembly 21. In this embodiment, a liquid outlet vertical branch pipe 42 is connected to the heat exchange tube 211 near the air inlet side 11. Several liquid outlet vertical branches 42 are evenly arranged along the length of one side of the rack 1. The number of these liquid outlet vertical branches 42 is the same as the number of liquid inlet vertical branches 32, and their heights correspond one to one. The liquid outlet structure 4 also includes an upper liquid outlet assembly 43. This upper liquid outlet assembly 43 includes an upper branch pipe 431 connected to the liquid outlet manifold 41. The upper branch pipe 431 is located above the rack 1 and is arranged horizontally. The upper branch pipe 431 is connected to several upper liquid inlet branch pipes 432, which are connected to the heat exchange assembly 21. In this embodiment, the upper liquid inlet branch pipes 432 pass through the rack 1 and connect to the heat exchange tube 211 at the top of the rack 1.

[0032] Reference Figure 4 It can be understood that the transition and giving way method between the liquid inlet structure 3 and the liquid outlet structure 4, the transition connection method between the liquid inlet main pipe 31 and the liquid inlet vertical branch pipe 32, the transition connection method between the lower branch pipe 331 and the lower liquid inlet branch pipe 332, the transition connection method between the liquid outlet main pipe 41 and the liquid outlet vertical branch pipe 42, and the transition connection method between the upper branch pipe 431 and the upper liquid inlet branch pipe 432 can be adjusted according to actual needs. Specifically, it can be a circular arc tube transition connection or a straight tube transition connection.

[0033] By providing an inclined heat exchange assembly 21, the heat exchange tubes 211 are tilted from the air inlet side 11 to the air outlet side 12. Furthermore, the liquid inlet structure 3 is positioned on the air outlet side 12, and the liquid outlet structure 4 is positioned on the air inlet side 11. When the antifreeze cooler is operating, the liquid inlet structure 3 drives the heat transfer medium into the cooler from the end of the heat exchange tubes 211 located on the air outlet side 12. The heat transfer medium then flows through the cooler from the end of the heat exchange tubes 211 located on the air inlet side 11 to the liquid outlet structure 4. When the cooler is shut down or stops operating, gravity automatically causes the heat transfer medium to flow back from the end of the heat exchange tubes 211 located on the air inlet side 11 to the end of the heat exchange tubes 211 located on the air outlet side 12. This ensures automatic emptying, eliminating the need for manual operation and ensuring effective emptying, thus achieving effective antifreeze protection.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
