[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0044] The core of this invention is to provide a condenser that is relatively easy to assemble.

[0045] Please refer to Figure 1 This utility model provides a condenser, including a housing 1, coils 2, and a mounting bracket 3. The coils 2 are disposed within the inner cavity of the housing 1, and several coils 2 are arranged along the height direction of the housing 1. The mounting bracket 3 has several mounting slots 31, and is installed on the inner wall of the housing 1. The first sections of several coils 2 are engaged with corresponding mounting slots 31, so that several coils 2 are mounted on one mounting bracket 3.

[0046] like Figure 1 and Figure 2 As shown, housing 1 is a hollow structure used to install and support coil 2, mounting bracket 3, etc.; furthermore, as Figures 1 to 5 As shown, a fixing bracket 3 is fixedly installed on the left and right ends of the inner wall of the box 1. Each fixing groove 31 on the fixing bracket 3 is arranged vertically. Several coils 2 are arranged vertically in the inner cavity of the box 1. The bending and turning pipe sections 22 of several coils 2 along the left end of the horizontal direction are locked in the corresponding fixing grooves 31 on the fixing bracket 3 at the left end of the box 1. The bending and turning pipe sections 22 of several coils 2 along the right end of the horizontal direction are locked in the corresponding fixing grooves 31 on the fixing bracket 3 at the right end of the box 1. During assembly, the fixing bracket 3 is engaged with the bending and turning pipe sections 22 of several coils 2 through the fixing grooves 31. Then, the fixing bracket 3 is installed on the box 1 by welding or screws. This greatly reduces the assembly difficulty and the installation stability of the coils 2 is high.

[0047] It should be noted that the type of fixing bracket 3 is not limited, as long as it can accommodate several vertically arranged coils 2. For example, the fixing bracket 3 can adopt a U-shaped structure, with several fixing slots 31 opened on the sides of the two vertical rods of the U-shaped structure. The bent and turning pipe section 22 on one side of the coil 2 is engaged with the fixing slot 31 of one vertical rod, and the bent and turning pipe section 22 on the other side of the coil 2 is engaged with the fixing slot 31 of another vertical rod.

[0048] It should also be noted that the type of fixing groove 31 is not limited, as long as it can be engaged with the bent and turning pipe section 22 of the coil 2. For example, the fixing groove 31 can be a rectangular groove, or the fixing groove 31 can also be a U-shaped groove, etc.

[0049] Based on the above embodiment, the bent and turning pipe section 22 is located between the corresponding fixing frame 3 and the corresponding box wall of the box body 1.

[0050] like Figures 1 to 5 As shown, the side of the mounting bracket 3 with the slot 31 faces the wall of the housing 1. After the mounting bracket 3 is installed on the housing 1, the bent and turning pipe section 22 is located between the corresponding mounting bracket 3 and the corresponding wall of the housing 1 to further improve the positioning and fixing ability of the coil 2.

[0051] Based on the above embodiment, the coil 2 is a serpentine tube, having several parallel straight tube segments 21, with bending and turning tube segments 22 connecting the adjacent ends of adjacent straight tube segments 21. It should be noted that a serpentine tube refers to a tube that meanders multiple times within a plane.

[0052] like Figures 1 to 5 As shown, the coil 2 adopts a serpentine tube, which includes several straight tube segments 21 and bent turning tube segments 22. From left to right, the left ends of adjacent first and second straight tube segments 21 are connected by bent turning tube segments 22 located on the left side and in an arc or V shape. The right ends of adjacent second and third straight tube segments 21 are connected by bent turning tube segments 22 located on the right side and in an arc or V shape. The connection relationship between the third, fourth, ... nth straight tube segments 21 and the corresponding bent turning tube segments 22 is the same as the connection relationship between the first, second, and third straight tube segments and the corresponding bent turning tube segments 22.

[0053] Based on the above embodiment, the bottom of the fixing groove 31 is an arched structure, and the bottom wall of the fixing groove 31 is in contact with the inner arc surface of the bent turning pipe section 22.

[0054] like Figure 11As shown, in coil 2, adjacent corresponding straight pipe sections 21 are connected by an arc-shaped bent turning pipe section 22. Correspondingly, the bottom of the fixing groove 31 is processed into an arched structure, which is recessed into the groove. After the bent turning pipe section 22 is snapped into the fixing groove 31, the bottom wall of the fixing groove 31 abuts against the inner arc surface of the bent turning pipe section 22. The inner arc surface refers to the outer peripheral surface with a smaller radius in the arc-shaped bent turning pipe section 22. Preferably, the bottom radius of the fixing groove 31 is equal to the radius R of the inner arc surface of the corresponding bent turning pipe section 22, that is, the bottom wall of the fixing groove 31 and the inner arc surface of the bent turning pipe section 22 are in full contact.

[0055] Based on the above embodiment, the depth and width of the fixing groove 31 are both equal to the maximum cross-sectional width of the corresponding bent turning pipe section 22.

[0056] like Figure 10 As shown, the depth H and width B of the fixing groove 31 are both equal to the maximum cross-sectional width D of the bent and turning pipe section 22. The width B of the fixing groove 31 refers to the distance between the upper and lower groove walls of the fixing groove 31. For example, when the bent and turning pipe section 22 is a rectangular pipe section, the depth H and width B of the fixing groove 31 are equal to the maximum side length of the bent and turning pipe section 22; or, when the bent and turning pipe section 22 is a circular pipe section, the depth H and width B of the fixing groove 31 are equal to the outer diameter of the bent and turning pipe section 22. With this configuration, the bent and turning pipe section 22 can be completely embedded in the fixing groove 31.

[0057] Based on the above embodiment, the angle between the fixing groove 31 and the horizontal direction is equal to the angle between the corresponding bent turning pipe section 22 and the horizontal direction.

[0058] like Figure 4 , Figure 5 and Figure 9 As shown, the angle G1 between the fixed groove 31 and the horizontal direction is the angle between the upper and lower groove walls of the fixed groove 31 and the horizontal direction. The angle G between the bent and turning pipe section 22 and the horizontal direction refers to the angle at which the coil 2 is to be installed relative to the horizontal direction. Since G1=G, the bent and turning pipe section 22 can extend along the length of the fixed groove 31. This setting helps to improve the positioning accuracy of the coil 2.

[0059] Based on the above embodiment, the fixing frame 3 is a straight rod, and a plurality of fixing grooves 31 are arranged along the length direction of the fixing frame 3, and the fixing grooves 31 are through the width direction of the fixing frame 3.

[0060] like Figure 8As shown, the fixing frame 3 adopts a straight rod body, and several fixing grooves 31 are opened on one side of the fixing frame 3, which are arranged along the length of the fixing frame 3. The fixing grooves 31 are recessed inward along the height of the fixing frame 3, and each fixing groove 31 is a through groove that runs through the width of the fixing frame 3. The fixing frame 3 can be fixedly connected to the box 1 with at least two connectors or welding points. This setting can not only reduce the assembly difficulty, but also make the fixing frame 3 simple in structure, with low cost and low manufacturing difficulty, and facilitate the installation of different numbers of coils 2.

[0061] Based on the above embodiment, the box wall of the box body 1 is provided with an inlet connector 5 and an outlet connector 6; the first end of the inlet connector 5 and the first end of the outlet connector 6 both extend into the inner cavity of the box body 1 and are respectively connected to the corresponding end of the coil 2; the second end of the inlet connector 5 and the second end of the outlet connector 6 are both located on the outside of the box body 1.

[0062] Coil 2 typically has an inlet end and an outlet end, with both ends having central openings to allow liquid to flow into or out of coil 2. In this embodiment, for example... Figures 1 to 3 As shown, an inlet connector 5 is inserted into the inlet end of the coil 2, and an outlet connector 6 is inserted into the outlet end of the coil 2.

The plurality of first insertion through holes and the plurality of second insertion through holes are evenly arranged in the vertical direction, and the inlet connectors 5 at one end of the plurality of coils 2 are inserted into the corresponding first insertion through holes, and the outlet connectors 6 at the other end of the plurality of coils are inserted into the corresponding second insertion through holes.

[0064] like Figure 2 As shown, several first insertion holes and second insertion holes are provided on the wall of the box body 1. Specifically, several first insertion holes are evenly arranged in a vertical row, and several second insertion holes are evenly arranged in a vertical row. Several inlet connectors 5 at one end of several serpentine tubes are inserted into the corresponding first insertion holes, and several outlet connectors 6 at the other end of several serpentine tubes are inserted into the corresponding second insertion holes.

[0065] It should be noted that the distribution of the first and second insertion holes is not limited. For example, in some embodiments, the first insertion hole is located on the back plate 12 of the housing 1, while the second insertion hole is located on the front panel 11 of the housing 1. Alternatively, preferably, in other embodiments, such as... Figure 2As shown, several first insertion holes and second insertion holes are provided on the panel 11 on the right side of the housing 1. The left ends of the inlet connector 5 and the outlet connector 6 are inserted into the corresponding first insertion holes and second insertion holes to connect to the coil 2 located inside the housing 1. The right ends of the inlet connector 5 and the outlet connector 6 are located on the outside of the housing 1 so as to be able to connect with the connectors of the external pipeline or external equipment.

[0066] Based on the above embodiments, the housing 1 includes a front panel 11, a back panel 12, a top panel 13, a bottom panel 14, a left side panel 15, and a right side panel 16. The front panel 11, back panel 12, top panel 13, bottom panel 14, left side panel 15, and right side panel 16 enclose a rectangular shell. The front panel 11 and back panel 12 are arranged opposite each other, the top panel 13 and bottom panel 14 are arranged opposite each other, and the left side panel 15 and right side panel 16 are arranged opposite each other. The front panel 11 and back panel 12 are each provided with a corresponding fixing bracket 3.

Correspondingly, a fixing bracket 3 is installed on the top of the front panel 11 and back panel 12. With this configuration, the condenser has a simple structure, good stability, and low production cost.

[0068] Based on any of the above embodiments, the mounting bracket 3 is installed on the housing 1 by fasteners 4.
