Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning heat exchangers, in particular to a quick-detachable air-conditioning heat exchanger. Background Art

[0002] The air conditioning heat exchanger is an important component of the air conditioning system, which is used to regulate the temperature of the indoor air. The heat exchanger achieves this purpose by transferring heat. It can absorb heat from the indoor air and release it to the outdoor environment, so that the indoor air temperature can be controlled. The heat exchanger is usually composed of multiple heat exchanger plates. The heat exchanger plate is the core component in the heat exchanger and plays a key role. They are usually made of materials with good thermal conductivity, such as aluminum or copper, so that heat can be transferred efficiently. The main function of the heat exchanger plate is to increase the heat exchange surface area so that heat can be absorbed or released more efficiently. By circulating air over the surface of the heat exchanger plate, the heat exchanger can achieve efficient heat transfer and thus regulate the temperature of the indoor air.

[0003] In the commonly used heat exchangers, the heat exchanger plates are usually pressed together with a frame structure and fastened with screws. Although this structure has the advantages of leak-proofness and stability, it has some inconveniences. First, such a structure is very inconvenient to disassemble, which is time-consuming and labor-intensive, and brings certain difficulties to maintenance and cleaning. Secondly, since the heat exchanger plates are easily damaged during use and have a high depreciation rate, they need to be replaced frequently, increasing maintenance costs. In addition, after heat exchange, this structure sometimes fails to reach the rated stable state at the cold water end, which may affect the performance stability of the entire system.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a quick-detachable air-conditioning heat exchanger, comprising a fixing frame, a heat exchange plate and a fastening plate, a plurality of the heat exchange plates are arranged on the inner side of the fixing frame, the fastening plate is slidably arranged on the inner side of the fixing frame and is located on one side of the heat exchange plate, a clamping strip is provided on the inner side of the fixing frame, and a clamping groove matching the clamping strip is provided on the heat exchange plate and the fastening plate, the fastening plate and the fixing frame are connected and fixed by a plurality of long bolts, a hot water inlet pipe, a hot water outlet pipe, a cold water inlet pipe and a cold water outlet pipe are connected on one side of the fixing frame, and a temperature supplement structure is connected between the hot water outlet pipe and the cold water outlet pipe.

[0006] Furthermore, the fixing frame is a square frame.

[0007] Based on the above characteristics, the shape of the heat exchange plate is adapted to facilitate the stable fixing of the heat exchange plate in the fixing frame.

[0008] Furthermore, an extension frame is symmetrically and integrally formed at one end of the fastening plate, and the other end of the extension frame is arranged outside the fixing frame and is rotatably connected to the same roller.

[0009] Based on the above features, the roller slides on the fixing frame, so that the fastening plate can be moved smoothly and conveniently, which is flexible and practical.

[0010] Furthermore, the long bolts are evenly spaced and symmetrically arranged on both sides of the heat exchange plate.

[0011] Based on the above characteristics, uniform force can be applied to the fastening plate to ensure its stability, thereby ensuring the stability of the heat exchanger plate.

[0012] Furthermore, the temperature supplement structure includes connecting pipe 1, connecting pipe 2 and a water pump, connecting pipe 1 is connected to the hot water outlet pipe, connecting pipe 2 is connected to the cold water outlet pipe, a fixed plate is connected to one side of the fixed frame, connecting pipe 1 and connecting pipe 2 are both connected to the water pump fixed on the fixed plate, connecting pipe 1 is connected to an electric control valve, and connecting pipe 2 is connected to a one-way valve.

[0013] Based on the above characteristics, the electric control valve can control the start and stop of the warm water replenishment structure according to needs, which is flexible and convenient. The one-way valve can prevent hot water backflow and ensure system stability.

[0014] Furthermore, the hot water outlet pipe and the cold water outlet pipe are both connected to a temperature detector.

[0015] Based on the above characteristics, the temperature detector can detect the water temperature in the hot water outlet pipe and the cold water outlet pipe in real time, and then control the operation of the warm water replenishment structure as needed.

[0016] Compared with the prior art, the utility model has the following advantages: the heat exchanger is fixed by the fastening plate and the fixing frame, and does not need to be fixed by bolts alone, which is convenient for quick disassembly and assembly. At the same time, the arrangement of the clamping block and the clamping groove can stably clamp the heat exchanger on the inner side of the fixing frame. The fastening plate is fastened by long bolts to ensure that the heat exchanger is tightly fixed, further increasing its stability. The temperature supplement structure connects the hot water outlet pipe and the cold water outlet pipe through connecting pipe one and connecting pipe two, which is convenient for mixing part of the hot water into the cold water to achieve temperature supplement, ensuring that the cold water end is quickly in a stable state, and ensuring the stability of the system.
