Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an improved air source heat pump heat exchanger. Background Technology

[0002] Air source heat pumps, as a highly efficient, energy-saving, and environmentally friendly heating and cooling equipment, have been widely used. As one of the core components of an air source heat pump, the performance of the heat exchanger directly affects the overall performance of the air source heat pump. The heat exchanger is mainly composed of fins and heat dissipation pipes. Airflow is blown in and passes through the gaps between the fins, thereby achieving the effect of heat exchange between the fins.

[0003] After prolonged use, the fins in an air source heat pump heat exchanger will accumulate a lot of dust on their surface. Since the fins are usually densely distributed together, the accumulation of dust will affect the heat exchange efficiency of the fins. Furthermore, it is not convenient to clean the fins of existing heat exchangers during use. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: after prolonged use, the fins of an air source heat pump heat exchanger accumulate a lot of dust on their surface. Since the fins are generally densely distributed together, the accumulation of dust will affect the heat exchange efficiency of the fins. Furthermore, existing heat exchangers are not easy to clean during use. Therefore, this invention proposes an improved air source heat pump heat exchanger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An improved air source heat pump heat exchanger includes a body, a mounting groove on the surface of the body, multiple heat dissipation pipes evenly spaced in the mounting groove, fins on the heat dissipation pipes, a sliding opening on the side wall of the body, a slotted plate slidably inserted in the sliding opening, the slotted plate being locked by a locking assembly, and an L-shaped handle fixedly installed on one side of the slotted plate.

[0007] A mounting plate is fixedly installed on the surface of the slot plate. The surface of the mounting plate has multiple openings. Multiple heat dissipation pipes are located in the multiple openings respectively. A sponge ring is adhered to the wall of the opening. The inner ring wall of each sponge ring is in sliding contact with the surface of each fin.

[0008] Preferably, the surface of the groove plate has an installation opening, and a filter screen is fixedly embedded in the installation opening.

[0009] Preferably, the surface of the handle is bonded with an anti-slip layer, and the anti-slip layer is made of rubber.

[0010] Preferably, the locking assembly includes a crossbar and a locking rod fixedly installed on the handle surface. A slot is provided on one side of the device body, and the crossbar is slidably inserted into the slot. A through-hole communicating with the slot is provided on the top of the device body, and the locking rod is vertically slidably inserted into the through-hole. An installation block is fixedly installed on the top of the locking rod. The installation block is connected to the top of the device body through a telescopic component. A rectangular opening is provided on the surface of the crossbar for the bottom end of the locking rod to be inserted.

[0011] Preferably, the telescopic component includes a spring rod, the two ends of which are fixedly connected to the mounting block and the device body, respectively.

[0012] Preferably, the longitudinal section of the locking rod is trapezoidal, and the surface of the crossbar is provided with a plurality of triangular openings at equal intervals for insertion of the bottom end of the locking rod, and the inclined surface of the triangular opening is horizontally set with the inclined surface of the locking rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When it is necessary to clean the surface of the fins, the locking component can be released from the slot plate, and then the slot plate can be controlled to move laterally. At this time, multiple sponge rings will move together, and the inner ring wall will slide into contact with the surface of multiple fins respectively, thereby scraping off the dust accumulated on the surface of the fins and achieving the cleaning effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figures 1-7 An improved air source heat pump heat exchanger includes a body 1. The surface of the body 1 has an installation groove, and multiple heat dissipation pipes are arranged at equal intervals in the installation groove. The heat dissipation pipes are provided with fins 2. The side wall of the body 1 has a sliding opening, and a slot plate 3 is slidably inserted into the sliding opening. The slot plate 3 is locked by a locking component. An L-shaped handle 7 is fixedly installed on one side of the slot plate 3. The surface of the handle 7 is bonded with an anti-slip layer, and the anti-slip layer is made of rubber.

[0026] A mounting plate 4 is fixedly installed on the surface of the slot plate 3. Multiple through holes 5 are opened on the surface of the mounting plate 4. Multiple heat dissipation pipes are located in the multiple through holes 5 respectively. A sponge ring 6 is bonded to the wall of the through hole 5. The inner ring wall of each sponge ring 6 is in sliding contact with the surface of each fin 2.

[0027] When it is necessary to clean the surface of the fin 2 located in the mounting slot, first release the locking component from locking the slot plate 3, then control the slot plate 3 to move, and the mounting plate 4 will move together with the slot plate 3. During the movement, the surface of each fin 2 will slide into contact with the inner ring wall of each sponge ring 6, thereby scraping off the dust attached to the surface of the fin 2, making it easier to clean the fin 2.

[0028] The surface of the slot plate 3 has an installation port, and a filter screen 8 is fixedly embedded in the installation port. Ambient air can enter through the filter screen 8 and take away some heat. Especially when the device 1 is operating under high load or the ambient temperature is high, it can play an additional heat dissipation and cooling role, improve the overall heat dissipation efficiency, and at the same time, the filter screen 8 can also block impurities from entering.

[0029] The locking assembly includes a crossbar 9 and a locking rod 10 fixedly installed on the surface of the handle 7. A slot 11 is provided on one side of the body 1, and the crossbar 9 is slidably inserted into the slot 11. A through-hole connected to the slot 11 is provided on the top of the body 1. The locking rod 10 is vertically slidably inserted into the through-hole, and a mounting block is fixedly installed on the top of the locking rod 10. The mounting block is connected to the top of the body 1 through a telescopic component. The telescopic component includes a spring rod 13, and the two ends of the spring rod 13 are fixedly connected to the mounting block and the body 1, respectively. A rectangular opening 12 is provided on the surface of the crossbar 9 for the bottom end of the locking rod 10 to be inserted.

[0030] When the slot plate 3 completely blocks the opening of the mounting slot, the rectangular opening 12 will correspond to the position of the locking rod 10. Then, the bottom end of the locking rod 10 can be inserted into the rectangular opening 12 to lock the slot plate 3. When it is necessary to unlock, simply control the mounting block to move the locking rod 10 upwards, so that the bottom end of the locking rod 10 moves out of the rectangular opening 12. At this time, the spring rod 13 will be stretched.

[0031] The longitudinal section of the locking rod 10 is trapezoidal, and the surface of the crossbar 9 is provided with multiple triangular openings 14 for the bottom end of the locking rod 10 to be inserted. The inclined surface of the triangular opening 14 is set horizontally with the inclined surface of the locking rod 10.

[0032] When the cleaning of fin 2 is completed and the control plate 3 moves towards the sliding opening, the bottom end of the locking rod 10 will move vertically back and forth under the pressure of its own inclined surface and multiple triangular openings 14 and the elastic potential energy of the spring rod 13. The bottom end of the locking rod 10 will enter multiple triangular openings 14 in sequence. When entering the triangular openings 14, the bottom end of the locking rod 10 will collide with the opening wall of the triangular opening 14, which will apply an instantaneous impact force to the filter screen 8. This impact force will cause the filter screen 8 to vibrate mechanically. During the vibration, impurities such as dust, debris, and particles attached to the surface and mesh of the filter screen 8 will be removed from the filter screen 8 due to the inertial force generated by the vibration, thus achieving the effect of cleaning the filter screen 8.

[0033] In this invention, when it is necessary to clean the surface of the fin 2 located in the mounting groove, firstly, the locking component is released from locking the groove plate 3, and then the groove plate 3 is controlled to move. The mounting plate 4 will move together with the groove plate 3. During the movement, the surface of each fin 2 will slide into contact with the inner ring wall of each sponge ring 6, thereby scraping off the dust attached to the surface of the fin 2, making it easier to clean the fin 2.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
