[0026] 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.
[0027] Please see Figures 1-5The present invention provides the following technical solution:
[0028] A high-efficiency condensing heat exchanger includes a heat exchanger structure 1, a connecting pipe 4 fixedly connected to the left side of the heat exchanger structure 1, a filter box 5 fixedly connected to the left side of the connecting pipe 4, a water inlet pipe 6 fixedly connected to the left side of the filter box 5, a transmission mechanism 2 fixedly connected to the rear side of the water inlet pipe 6, and a heat insulation component 7 provided on the surface of the heat exchanger structure 1.
[0029] The transmission mechanism 2 includes a first valve 201, a connecting pipe 202, and a second valve 203. The front side of the connecting pipe 202 is fixedly connected to the rear side of the water inlet pipe 6. The first valve 201 is disposed on the surface of the connecting pipe 202. The front side of the connecting pipe 202 is fixedly connected to the rear side of the connecting pipe 4. The second valve 203 is disposed on the surface of the connecting pipe 202.
[0030] In this embodiment: By setting up a transmission mechanism 2, the first valve 201 and the second valve 203 in the transmission mechanism 2, together with the connecting pipe 202, can flexibly control the water flow path, making it easy to adjust the water flow when needed, such as for maintenance and repair of the heat exchanger structure 1 or to adjust the flow rate according to actual heat exchange requirements. At the same time, it can also cut off the water flow when some components fail, preventing the fault from spreading, and improving the reliability and maintainability of the heat exchanger structure 1. The heat insulation component 7 on the surface of the heat exchanger structure 1 can reduce the heat loss to the surrounding environment through the shell, improve energy utilization efficiency, avoid heat waste, and prevent the generation of condensate due to the shell temperature being too low, protecting the shell of the heat exchanger structure 1 from corrosion. By setting up a filter box 5, the water entering the heat exchanger structure 1 can be pre-treated by sequentially setting the connecting pipe 4, the filter box 5 and the water inlet pipe 6 on the left side of the heat exchanger structure 1, effectively intercepting impurities in the water, reducing the deposition of impurities inside the heat exchanger structure 1, reducing the risk of scaling and blockage, ensuring smooth flow in the internal channels of the heat exchanger structure 1, and thus maintaining efficient and stable heat exchange performance.
[0031] Specifically, such as Figure 2 As shown, a third valve 8 is provided on the surface of the water inlet pipe 6, and a fourth valve 9 is provided on the surface of the connecting pipe 4.
[0032] Specifically, such as Figure 3 As shown, a filter frame 10 is movably connected to the inner wall of the filter box 5, and a filter assembly 3 is snapped into the inner wall of the filter frame 10.
[0033] Specifically, such as Figure 4 As shown, the filter assembly 3 includes a holder 301 and a filter screen 302. The surface of the filter screen 302 is fixedly connected to the inner wall of the holder 301, and the surface of the holder 301 is engaged with the inner wall of the filter frame 10.
[0034] In this embodiment, the third valve 8 and the fourth valve 9 respectively installed on the surface of the inlet pipe 6 and the connecting pipe 4 can further refine the control of the water flow and can cut off the water flow when the filter box 5 is maintained. The movable filter frame 10 and the filter assembly 3 that are snapped into the filter frame 10 inside the filter box 5 facilitate the disassembly and replacement of the filter screen 302. When the filter screen 302 intercepts too many impurities and causes the filtration effect to decrease, it can be cleaned or replaced in time to continuously ensure the filtration effect of the water flow entering the heat exchanger structure 1 and reduce the impurities entering the interior of the heat exchanger structure 1.
[0035] Specifically, such as Figure 4 As shown, a mounting plate 11 is bolted to the front side of the filter frame 10, and the rear side of the mounting plate 11 contacts the front side of the filter box 5.
[0036] Specifically, such as Figure 3 As shown, a sealing ring 12 is bonded to the inner wall of the mounting plate 11, and the surface of the sealing ring 12 is engaged with the inner wall of the filter box 5. A handle 13 is bolted to the front side of the mounting plate 11.
[0037] In this embodiment: the mounting plate 11 on the front side of the filter frame 10 facilitates the disassembly and installation of the filter frame 10. The sealing ring 12 bonded to the inner wall of the mounting plate 11 is engaged with the inner wall of the filter box 5, which enhances the sealing performance of the filter box 5 and prevents water from leaking from the connection between the filter frame 10 and the filter box 5. The handle 13 on the front side of the mounting plate 11 makes it easier for operators to pull the filter frame 10, improving the convenience of maintenance.
[0038] Specifically, such as Figure 4 As shown, fixing blocks 14 are bolted to both the left and right sides of the mounting plate 11. A knob 15 is movably connected to the inner wall of the fixing block 14, and the surface of the knob 15 is threaded to the inner wall of the filter box 5.
[0039] Specifically, such as Figure 4 As shown, the inner wall of the filter frame 10 is provided with a slot 16 for use with the card holder 301, and the inner wall of the filter frame 10 is provided with a water inlet groove 17.
[0040] In this embodiment: the fixing blocks 14 and knobs 15 on both sides of the mounting plate 11 can firmly fix the filter frame 10 in the filter box 5, prevent the filter frame 10 from shifting under the impact of water flow, and ensure the stability of the filtration operation. The slots 16 opened on the inner wall of the filter frame 10 to cooperate with the card holder 301 facilitate the precise installation and positioning of the card holder 301. The design of the water inlet trough 17 can guide the water flow evenly through the filter screen 302, thereby improving the filtration efficiency.
[0041] Working Principle: During the use of heat exchanger structure 1, the transmission mechanism 2, with its first valve 201 and second valve 203 working in conjunction with the connecting pipe 202, allows for flexible control of the water flow path. This facilitates adjustment of the water flow as needed, such as for maintenance or repair of heat exchanger structure 1, or for adjusting the flow rate according to actual heat exchange requirements. It also allows for water flow interruption in case of component failure, preventing further damage and improving the reliability and maintainability of heat exchanger structure 1. The insulation components 7 on the surface of heat exchanger structure 1 reduce heat loss to the surrounding environment through the outer shell, improving energy efficiency and preventing heat waste. It also prevents condensation caused by excessively low shell temperature, protecting the outer shell of heat exchanger structure 1 from corrosion. The filter box 5, along with the connecting pipe 4, filter box 5, and inlet pipe 6 sequentially arranged on the left side of heat exchanger structure 1, pre-filters the water entering the heat exchanger structure 1, effectively intercepting impurities and reducing their deposition inside the structure. This reduces the risk of scaling and blockage, ensuring unobstructed flow within the structure and maintaining efficient and stable heat exchange performance.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
