Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning heat exchange, and specifically relates to an integrated air-conditioning heat exchanger. Background Art

[0002] An air conditioning heat exchanger is a heat exchange device used in air conditioning systems. It can move heat from indoors to outdoors or from outdoors to indoors to achieve the cooling or heating function of the air conditioning system. Air conditioning heat exchangers usually use refrigerants or water to transfer heat and achieve heat movement through circulating flow. In air conditioning systems, heat exchangers are an important component. They can help air conditioning systems achieve efficient cooling and heating effects and improve indoor comfort.

[0003] After searching, a document with publication number (CN202853086U) discloses a multi-type air-conditioning heat exchanger, including U-shaped copper tubes and fins, wherein the U-shaped copper tubes are arranged in parallel inside the fins, the inlet end of the U-shaped copper tubes is connected to the diverter and the electronic expansion valve, and the outlet end of the U-shaped copper tubes is connected to the gas collecting pipe; by adopting U-shaped copper tubes with an outer diameter of less than 5 mm in combination with a parallel arrangement structure, and cooperating with an electronic expansion valve for regulation.

[0004] The above-mentioned device adopts U-shaped copper tubes with an outer diameter of less than 5mm to replace the existing U-shaped copper tubes with an outer diameter of 7mm and above. During the use of the air conditioner, the original performance is guaranteed while saving the use of copper tubes, which is energy-saving and environmentally friendly. However, manufacturers in the market currently adopt the method of adding water modules to realize the natural fluorine and ground water system. However, since the structure of the air conditioner outdoor unit is similar to the ordinary multi-split structure, it only has a connecting pipe interface on the side of the Freon heat exchange device. If the water module is to be connected, it is inevitable to add complex water pipelines, which increases the difficulty of engineering layout. At the same time, the water module will also occupy a larger usable space.

[0005] In view of this, the present utility model is proposed. Utility Model Content
