Embodiment 1
[0013] like figure 1 As shown, the condenser of the miniature microchannel heat pump type air conditioner described in this embodiment is embedded with electric heating wires, and it includes a heat exchanger 1 and a heater 2. The heater 2 is composed of an electric heating network composed of electric heating wires 3 ; The heat exchanger 1 is composed of an inlet pipe 4 and an outlet pipe 5 connected by a miniature microchannel metal round tube 6, and the inner diameter of the miniature microchannel metal round tube 6 is 0.1mm; the heat exchanger 1 and The heaters 2 are fixed by the guard plate 7 and arranged at intervals. In order to facilitate the fixing of the heating wire 3 and avoid the contact between the heating wire 3 and the heat exchanger 1, the heating network on the heater 2 is composed of the heating wire 3 and a fixing object, wherein the fixing object can be directly a fixing frame 8. The metal round pipes 6 with micro-channels are fixed by wires 9 to form a ...

Abstract
The invention provides a condenser embedded with heating wires for a mini microchannel heat pump type air conditioner. The condenser is composed of a heat exchanger and a heater, wherein the heater consists of an electric heating network composed of the heating wires; the heat exchanger is formed by connecting an inlet pipe with an outlet pipe through a mini microchannel metal round tube of which the internal diameter is between 0.1 mm and 0.4 mm; and the heat exchanger and the heater are fixed by virtue of a backplate and are separately arranged. The condenser with such a structure has the following characteristics: the mini microchannel metal round tube is used as a main heat exchange component, so that the volume of the whole heat exchanger is reduced; and the condenser is properly heated by virtue of the heating wires, so that the purpose of deriming or avoid frost formation is achieved.
Description
technical field [0001] It is used in the fields of air-cooled industrial air conditioners, civil air conditioners and vehicle air conditioners, or microelectronics and air energy water heaters. Background technique [0002] When the current heat pump air conditioner is heating, frost will form on the side of the outdoor unit at a certain time, and it needs to switch to the cooling mode to make the heat exchanger heat and defrost. Reduced heating effect. The existing method is to use heat sinks of electric heating compressors and electric heating heat exchangers to shorten the defrosting time. Some use PTC heating sheets, and some use resistance wires. However, due to the large windward area of the outdoor unit, heating consumes energy. Big, poor effect. Contents of the invention [0003] The object of the present invention is to provide a small volume, no frosting or short defrosting time, and energy-saving miniature microchannel heat pump type air conditioner with emb...
