Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a combined heat exchanger. Background Technology

[0002] A heat exchanger is a device used to transfer heat between different fluids. It achieves heat exchange and energy utilization by transferring heat energy from one fluid to another. Heat exchangers are widely used in various fields, including industry, construction, chemical, energy, and automotive sectors.

[0003] However, in actual use, existing equipment often uses multiple sets of bolts to fix the two heat exchangers. When the lower heat exchanger needs to be replaced, multiple sets of bolts need to be removed and the upper heat exchanger needs to be taken off, which requires a lot of manpower and time to replace the heat exchanger. In view of this, we propose a combined heat exchanger. Utility Model Content

[0004] The purpose of this invention is to provide a combined heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined heat exchanger, comprising a lower heat exchanger, a feed pipe fixedly connected to one end of the lower heat exchanger, a discharge pipe fixedly connected to one end of the lower heat exchanger near the feed pipe, a connecting pipe fixedly connected to the outer wall of the lower heat exchanger, a water pump fixedly connected to one end of the connecting pipe away from the lower heat exchanger, an upper heat exchanger fixedly connected to the outer wall of the water pump, and an installation assembly provided on the exterior of the lower heat exchanger, the installation assembly comprising:

[0006] Mounting plate, which is fixedly connected to both ends of the lower heat exchanger, has a bracket attached to its outer wall, and the bracket has an installation groove on its outer wall. A connecting plate is fixedly connected to the upper outer wall of the bracket.

[0007] The rotating base is fixedly connected to the outer wall of the bracket. The inner wall of the rotating base is rotatably connected to a rotating plate. The outer wall of the connecting plate is fixedly connected to a fixed seat. The fixed seat and the outer wall of the rotating plate are both threadedly connected with a lower bolt.

[0008] Preferably, there are two sets of rotating seats, which are symmetrically distributed on the outer wall of the support. The inner walls of both sets of rotating seats are rotatably connected to rotating plates, so that the rotating seats can fix the mounting plates of the upper heat exchanger and the lower heat exchanger respectively, thereby fixing the positions of the upper and lower heat exchangers.

[0009] Preferably, the bracket has a fixing component inside, the fixing component including a cover plate, the cover plate being rotatably connected to a rotating plate at the upper end of the bracket, the end of the cover plate away from the rotating plate being threaded with an upper bolt, a locking block being fixedly connected to the outer wall of the rotating plate rotatably connected to the cover plate, and a locking groove being formed on the inner wall of the cover plate, so that when the cover plate is rotated to fit against the outer wall at the upper end of the mounting plate, the locking block can engage with the locking groove, thereby fixing the position of the rotating plate and the cover plate.

[0010] Preferably, the end of the cover plate away from the rotating plate contacts the bracket, and the upper bolts pass through the cover plate and the bracket and are threadedly connected to both the cover plate and the bracket. This allows the rotating plate and the cover plate to be rotated when the mounting plate, which is fixedly connected to the upper heat exchanger, is placed on the bracket, so that all four sides of the mounting plate can contact the bracket, the rotating plate, and the cover plate respectively, thus fixing the mounting plate in place on all four sides.

[0011] Preferably, the mounting groove is the same size as the mounting plate, the mounting groove is engaged with the mounting plate, and the inner wall of the rotating plate is provided with mounting grooves so that when the mounting plate is placed on the bracket, the mounting plate can be engaged with the mounting groove, and the rotating plate can press the mounting plate into the mounting groove after rotation.

[0012] Preferably, both ends of the upper heat exchanger and both ends of the lower heat exchanger are fixedly connected to the mounting plate, and both ends of the connecting plate are fixedly connected to the brackets, so that both ends of the upper heat exchanger and the lower heat exchanger can be fixed, and both ends of the upper heat exchanger and the lower heat exchanger are fixed when they are in use.

[0013] Preferably, the size of the slot matches the size of the block, the block is fixedly connected directly below the connection between the cover plate and the rotating plate, the block is hemispherical, and the block engages with the slot to keep the position of the cover plate and the rotating plate above the bracket stable.

[0014] Compared with the prior art, this utility model provides a combined heat exchanger with the following advantages:

[0015] 1. This combined heat exchanger uses a rotating plate to push the mounting plate on the lower heat exchanger into the mounting groove at the lower end of the bracket. Then, the rotating plate can be rotated to engage with the fixed seat. The lower bolt passes through both the fixed seat and the rotating plate, keeping the mounting plate fixed inside the bracket. At this point, the lower heat exchanger is individually fixed. When disassembly is required, simply tighten the lower bolt to move the lower heat exchanger while keeping the upper heat exchanger stationary, saving a significant amount of time and manpower.

[0016] 2. This combined heat exchanger allows the mounting plate of the upper heat exchanger to be snapped into the bracket. Then, the rotating plate and the cover plate can be rotated and the bolts tightened to fix the mounting plate on all four sides. The locking block and the locking slot engage to keep the position of the cover plate and the rotating plate above the bracket stable. This allows the upper heat exchanger to be easily fixed to the upper end of the bracket. Unlocking only requires turning the bolts, which saves a lot of time and manpower.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a combined heat exchanger, including a lower heat exchanger 1, a feed pipe 2 fixedly connected to one end of the lower heat exchanger 1, a discharge pipe 3 fixedly connected to one end of the lower heat exchanger 1 near the feed pipe 2, a connecting pipe 4 fixedly connected to the outer wall of the lower heat exchanger 1, a water pump 5 fixedly connected to one end of the connecting pipe 4 away from the lower heat exchanger 1, an upper heat exchanger 6 fixedly connected to the outer wall of the water pump 5, and an installation assembly 7 provided on the outside of the lower heat exchanger 1, the installation assembly 7 including an installation plate 71, a bracket 72, an installation groove 73, a connecting plate 74, a rotating seat 75, a rotating plate 76, a fixed seat 77, and a lower bolt 78.

[0024] In one embodiment of the present invention, the mounting plate 71 is fixedly connected to both ends of the lower heat exchanger 1, the outer wall of the mounting plate 71 is fitted with a bracket 72, the outer wall of the bracket 72 is provided with a mounting groove 73, and the upper outer wall of the bracket 72 is fixedly connected with a connecting plate 74.

[0025] In one embodiment of the present invention, the rotating base 75 is fixedly connected to the outer wall of the bracket 72, the inner wall of the rotating base 75 is rotatably connected to the rotating plate 76, the outer wall of the connecting plate 74 is fixedly connected to the fixing seat 77, and the outer walls of the fixing seat 77 and the rotating plate 76 are both threadedly connected to the lower bolt 78.

[0026] In addition, there are two sets of rotating seats 75, which are symmetrically distributed on the outer wall of the support 72. The inner walls of the two sets of rotating seats 75 are rotatably connected to rotating plates 76, so that the rotating seats 75 can fix the mounting plate 71 of the upper heat exchanger 6 and the mounting plate 71 of the lower heat exchanger 1 respectively, so that the positions of the upper heat exchanger 6 and the lower heat exchanger 1 are fixed, thereby enabling the upper heat exchanger 6 and the lower heat exchanger 1 to be stably connected.

[0027] In an embodiment of this utility model, a fixing component 8 is provided inside the bracket 72. The fixing component 8 includes a cover plate 81, which is rotatably connected to a rotating plate 76 at the upper end of the bracket 72. An upper bolt 82 is threadedly connected to the end of the cover plate 81 away from the rotating plate 76. A locking block 83 is fixedly connected to the outer wall of the rotating plate 76, which is rotatably connected to the cover plate 81. A locking groove 84 is provided on the inner wall of the cover plate 81, so that when the cover plate 81 is rotated to fit against the outer wall of the upper end of the mounting plate 71, the locking block 83 can engage with the locking groove 84, thereby fixing the position of the rotating plate 76 and the cover plate 81. This allows the cover plate 81 to better fix the mounting plate 71 on the upper heat exchanger 6 to the bracket 72.

[0028] In this embodiment of the present invention, the end of the cover plate 81 away from the rotating plate 76 contacts the bracket 72. The upper bolt 82 passes through the cover plate 81 and the bracket 72 and is threadedly connected to both the cover plate 81 and the bracket 72. When the mounting plate 71, which is fixedly connected to the upper heat exchanger 6, is placed on the bracket 72, the rotating plate 76 and the cover plate 81 can be rotated so that the four sides of the mounting plate 71 can contact the bracket 72, the rotating plate 76 and the cover plate 81 respectively, so that the four sides of the mounting plate 71 can be fixed, and the upper heat exchanger 6 and the lower heat exchanger 1 can be stably connected.

[0029] In the embodiments of this utility model, the mounting groove 73 is matched in size with the mounting plate 71, and the mounting groove 73 is engaged with the mounting plate 71. The inner wall of the rotating plate 76 is provided with mounting grooves 73, so that when the mounting plate 71 is placed on the bracket 72, the mounting plate 71 can be engaged with the mounting groove 73, so that after the rotating plate 76 rotates, the rotating plate 76 can press the mounting plate 71 into the mounting groove 73, so that the mounting plate 71 can be more stably fixed on the bracket 72.

[0030] In the embodiments of this utility model, both ends of the upper heat exchanger 6 and both ends of the lower heat exchanger 1 are fixedly connected to the mounting plate 71, and both ends of the connecting plate 74 are fixedly connected to the bracket 72, so that both ends of the upper heat exchanger 6 and the lower heat exchanger 1 can be fixed, so that both ends of the upper heat exchanger 6 and the lower heat exchanger 1 are fixed when in use, and so that the upper heat exchanger 6 and the lower heat exchanger 1 can remain stable during operation.

[0031] In this embodiment of the utility model, the size of the slot 84 matches the size of the block 83. The block 83 is fixedly connected directly below the connection between the cover plate 81 and the rotating plate 76. The block 83 is set as a hemispherical shape. The block 83 engages with the slot 84, so that the position of the cover plate 81 and the rotating plate 76 above the bracket 72 can remain stable, thereby allowing the cover plate 81 and the rotating plate 76 above the bracket 72 to stably fix the heat exchanger according to step 6.

[0032] In this invention, during use, the rotating plate 76 can be rotated to push the mounting plate 71 on the lower heat exchanger 1 into the mounting groove 73 at the lower end of the bracket 72. Then, the rotating plate 76 can be rotated to engage with the fixing seat 77. Finally, the lower bolt 78 is rotated, simultaneously penetrating the fixing seat 77 and the rotating plate 76, ensuring the mounting plate 71 remains inside the bracket 72. This allows the lower heat exchanger 1 to be individually fixed. When disassembly is required, only one set of bolts needs to be tightened to contact and fix the lower heat exchanger 1, while the upper heat exchanger 6 remains stationary, saving significant time and manpower. At this point, the upper heat exchanger 6 can be disassembled. The mounting plate 71 of the device 6 is inserted into the bracket 72. Then, the rotating plate 76 and the cover plate 81 can be rotated to fix the mounting plate 71 on all sides. The locking block 83 and the locking groove 84 are engaged to keep the position of the cover plate 81 and the rotating plate 76 above the bracket 72 stable, so that the upper heat exchanger 6 and the lower heat exchanger 1 can be stably connected. At this time, the hot water to be exchanged can be poured in from the feed pipe 2 and discharged from the discharge pipe 3. At this time, the cooling water can be introduced from the lower heat exchanger 1 into the upper heat exchanger 6 through the water pump 5 for cooling, so that the upper heat exchanger 6 can better cool the cooling water.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
