Description

Technical Field

[0001] This utility model relates to the field of heat exchanger accessory technology, specifically to a quick-installation structure for heat exchangers. Background Technology

[0002] When installing microchannel heat exchangers on-site, each heat exchanger is typically mounted within a frame using four sets of fasteners, such as... Figure 1 and Figure 7 As shown, there are two sets of heat exchanger tubes between each heat collector tube and the frame;

[0003] Fasteners typically use bolt and nut fastening structures. If a large number of heat exchangers need to be installed, a significant amount of time needs to be spent on-site for the installation of the bolts and nuts, which not only consumes a lot of manpower but also takes a long time to install the heat exchangers.

[0004] Based on this, the present invention designs a quick-installation structure for a heat exchanger to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a quick installation structure for heat exchangers.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-installation structure for a heat exchanger includes a support frame;

[0008] The support frame is composed of four rectangular aluminum profiles that are fixedly connected by connectors. The top and bottom of the support frame are respectively provided with top fixing and bottom fixing. The top fixing and bottom fixing cooperate to clamp and fix the heat exchanger from the top and bottom sides.

[0009] The top fixing component includes a fixing block and a buckle. The fixing block is fixedly connected to the aluminum profile by a bolt and nut fastening structure. The lower end of the fixing block is fixedly connected to a buckle, which is set to be arc-shaped to tightly engage with the heat collection tube of the heat exchanger.

[0010] The bottom fixing component includes a slider and a bottom bracket. The slider is inserted into the groove of the aluminum profile. The upper end of the slider is fixedly installed with a bottom bracket for supporting the heat exchanger's heat collection tube and limiting its front and rear movement.

[0011] Furthermore, the bottom bracket adopts a first bracket structure, which includes a first inclined plate and a second inclined plate. The lower ends of the first inclined plate and the second inclined plate are fixedly connected to form a V-shaped support structure, and the lower end of the V-shaped support structure is welded to the slider.

[0012] Furthermore, the bottom bracket adopts a second bracket structure, which includes a first inclined plate, a second inclined plate, and a U-shaped frame. The first and second inclined plates are fixedly installed at both ends of the U-shaped frame, and the bottom of the U-shaped frame is connected to the slider by spring nuts and bolts.

[0013] Furthermore, the bottom bracket adopts a third bracket structure, which includes a second bracket structure, a first vertical plate, and a second vertical plate. The lower ends of the first vertical plate and the second vertical plate are fixedly connected to the first inclined plate and the second inclined plate, respectively.

[0014] Furthermore, the third bracket structure also includes a first guide plate and a second guide plate, the lower ends of which are fixedly connected to the upper ends of the first vertical plate and the second vertical plate, respectively.

[0015] Furthermore, the buckle adopts a plastic buckle structure, which consists of an arc-shaped frame and a guide block. An aluminum slider for inserting into the groove of the aluminum profile is fixedly installed at the lower end of the arc-shaped frame, and guide blocks are fixedly installed at both ends of the arc-shaped frame.

[0016] Furthermore, the central angle of the curved frame is greater than 200 degrees.

[0017] Furthermore, the buckle adopts a plastic buckle structure, which consists of a positioning angle iron and a limiting side plate. The lower end of the positioning angle iron is fixedly installed with an aluminum slider for inserting into the groove of the aluminum profile; one end of the positioning angle iron is fixedly installed with a limiting side plate, and the lower end of the limiting side plate is inclined towards the positioning angle iron.

[0018] Compared with the prior art, the advantages of this utility model are as follows: 1. This utility model changes the four sets of fasteners required for installing the heat exchanger. It retains the two sets of bolt and nut fastening structures at the top of the heat exchanger and replaces the two sets of bolt and nut fastening structures at the bottom of the heat exchanger with two sets of bottom fixing parts. The bottom fixing parts can be pre-installed on the support frame before the support frame is shipped. When installing the heat exchanger on site, the heat collection tube at the bottom of the heat exchanger is positioned by the bottom bracket and its front and rear freedom is restricted. Then, the clips are fastened to the heat collection tube at the top, and the fixing blocks are fixed to the top of the support frame by bolts and nuts to achieve the effect of fixing the heat exchanger. This can save about half of the time for on-site installation of the heat exchanger, effectively improve the efficiency of heat exchanger disassembly and assembly, and also facilitate the maintenance of the heat exchanger.

[0019] 2. The buckle can be a plastic buckle structure to replace the two sets of bolt and nut fastening structures on the top of the heat exchanger. This allows the buckle to be pre-installed on the support frame before shipment, thus eliminating all bolt and nut installation structures on the heat exchanger. When installing the heat exchanger on site, the heat collection tubes at the bottom of the heat exchanger are first placed on the bottom bracket, and then the heat collection tubes at the top of the heat exchanger are inserted into the arc-shaped frame along the guide block. The bottom bracket and the guide block work together to achieve a stable fastening effect on the heat exchanger, greatly reducing the time required for on-site installation. At the same time, the plastic buckle structure can effectively reduce costs. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] In some embodiments, please refer to the accompanying drawings. Figures 1-4 and Figure 7 A quick-installation structure for a heat exchanger includes a support frame 1;

[0035] The support frame 1 is composed of four rectangular aluminum profiles that are fixedly connected by connectors. The top and bottom of the support frame 1 are respectively provided with top fixing member 3 and bottom fixing member 4. The top fixing member 3 and bottom fixing member 4 cooperate to clamp and fix the heat exchanger 2 from the top and bottom sides.

[0036] The top fixing component 3 includes a fixing block 31 and a buckle 32. The fixing block 31 is fixedly connected to the aluminum profile by a bolt and nut fastening structure. The lower end of the fixing block 31 is fixedly connected to the buckle 32, which is set to be arc-shaped to tightly engage with the heat collection tube of the heat exchanger 2.

[0037] The bottom fixing component 4 includes a slider 41 and a bottom bracket 42. The slider 41 is made of aluminum and is inserted into the groove of the aluminum profile. The upper end of the slider 41 is fixedly installed with a bottom bracket 42 for supporting the heat collection tube of the heat exchanger 2 and limiting its front and rear movement.

[0038] This utility model modifies the four sets of fasteners required for heat exchanger installation. It retains the two sets of bolt and nut fastening structures at the top of the heat exchanger 2, and replaces the two sets of bolt and nut fastening structures at the bottom of the heat exchanger 2 with two sets of bottom fixing parts 4. The bottom fixing parts 4 can be pre-installed on the support frame 1 before the support frame 1 is shipped. When installing the heat exchanger 2 on site, the heat collection tube at the bottom of the heat exchanger 2 is positioned by the bottom bracket 42 and its front and rear freedom is restricted. Then, the buckle 32 is locked onto the heat collection tube at the top, and the fixing block 31 is fixed to the top of the support frame 1 by bolts and nuts to achieve the effect of fixing the heat exchanger 2. This can save about half of the time for on-site installation of the heat exchanger 2, effectively improve the disassembly and assembly efficiency of the heat exchanger 2, and also facilitate the maintenance of the heat exchanger 2.

[0039] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the bottom bracket 42 may adopt a first bracket structure, which includes a first inclined plate 421 and a second inclined plate 422. The lower ends of the first inclined plate 421 and the second inclined plate 422 are fixedly connected to form a V-shaped support structure, and the lower end of the V-shaped support structure is welded to the slider 41. The V-shaped support structure can provide effective support for the heat collection tube of the heat exchanger 2, and the first inclined plate 421 and the second inclined plate 422 can restrict the forward and backward movement of the heat collection tube.

[0040] In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, the bottom bracket 42 may adopt a second bracket structure. The second bracket structure includes a first inclined plate 421, a second inclined plate 422, and a U-shaped frame 423. The first inclined plate 421 and the second inclined plate 422 are fixedly installed at both ends of the U-shaped frame 423. The bottom of the U-shaped frame 423 is connected to the slider 41 by spring nuts and bolts. By setting the U-shaped frame 423, the stability of the bottom bracket 42 in supporting the heat collection tube of the heat exchanger 2 can be increased.

[0041] In some embodiments, such as Figure 6 As shown, in a preferred embodiment of the present invention, the bottom bracket 42 may adopt a third bracket structure, which includes a second bracket structure, a first vertical plate 424 and a second vertical plate 425. The lower ends of the first vertical plate 424 and the second vertical plate 425 are fixedly connected to the first inclined plate 421 and the second inclined plate 422, respectively. The first vertical plate 424, the second vertical plate 425, the first inclined plate 421 and the second inclined plate 422 fit the contour of the heat collection tube better, which can increase the limiting effect on the heat collection tube.

[0042] The third bracket structure also includes a first guide plate 426 and a second guide plate 427. The lower ends of the first guide plate 426 and the second guide plate 427 are fixedly connected to the upper ends of the first vertical plate 424 and the second vertical plate 425, respectively. During installation, the heat collection tubes of the heat exchanger 2 can be placed more easily on the U-shaped frame 423 along the first guide plate 426 and the second guide plate 427, making the installation of the heat exchanger 2 more convenient.

[0043] In some embodiments, such as Figure 8 As shown, in a preferred embodiment of this utility model, the buckle 32 can be a plastic buckle structure. The buckle 32 of the plastic buckle structure is composed of an arc-shaped frame 321 and a guide block 322. An aluminum slider for inserting into the groove of the aluminum profile is fixedly installed at the lower end of the arc-shaped frame 321. The central angle of the arc-shaped frame 321 is greater than 200 degrees, which can tightly fix the heat collection tube. The guide blocks 322 are fixedly installed at both ends of the arc-shaped frame 321 respectively.

[0044] Using plastic clips 32 can effectively reduce costs and replace the two sets of bolt and nut fastening structures on the top of the heat exchanger 2. Clips 32 can also be pre-installed on the support frame 1 before shipment, thereby eliminating all bolt and nut installation structures of the heat exchanger 2. When installing the heat exchanger 2 on site, first place the heat collection tube at the bottom of the heat exchanger 2 on the bottom bracket 42, and then insert the heat collection tube at the top of the heat exchanger 2 into the arc frame 321 along the guide block 322. The bottom bracket 42 and the guide block 322 work together to achieve a stable fastening effect on the heat exchanger 2, greatly reducing the time required for on-site installation of the heat exchanger 2.

[0045] In some embodiments, such as Figure 9 As shown, in a preferred embodiment of this utility model, the snap fastener 32 of the plastic structure can also be composed of a positioning angle iron 323 and a limiting side plate 324. The lower end of the positioning angle iron 323 is fixedly installed with an aluminum slider for insertion into the groove of the aluminum profile; one end of the positioning angle iron 323 is fixedly installed with the limiting side plate 324, and the lower end of the limiting side plate 324 is inclined towards the positioning angle iron 323. The design of the positioning angle iron 323 and the limiting side plate 324 can reduce material consumption while ensuring good support for the heat collection tube, thereby further reducing the cost of the snap fastener 32; during installation, the heat collection tube is inserted into the positioning angle iron 323 and the inner side of the limiting side plate 324 along the inclined part of the lower end of the limiting side plate 324 to achieve the fastening effect of the heat exchanger 2.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
