When the air conditioner heats, the high-pressure gaseous refrigerant is sprayed into the evaporator by the compressor, the refrigerant liquefies and releases heat, then the refrigerant is decompressed and enters the condenser by the throttling component, the refrigerant evaporates and absorbs heat in the condenser, but when the outside air temperature is lower than 5 ℃, the evaporating temperature of the refrigerant in the condenser is lower than 0 ℃, the surface of the condenser is frosted, the lower the outside temperature is, the more serious the frosting phenomenon is, the frequent stopping of the compressor is required, and the air conditioner cannot heat normally.

Illustratively, as shown in connection with fig. 1 and 2, a plurality of electric heating plates 20 are disposed at uniform intervals, and four fins 11 are disposed between adjacent electric heating plates 20.

Alternatively, the number of the connection members 30 is one less than the number of the electric heating plates 20. Specifically, when the number of the electric heating plates 20 is two, the number of the connecting members 30 is one, and the connecting member 30 is provided between the two electric heating plates 20 with one end connected to one of the electric heating plates 20 and the other end connected to the other electric heating plate 20 so that an electric current can flow from one of the electric heating plates 20 to the other electric heating plate 20 through the connecting member 30. When the number of the electric heating plates 20 is plural, the number of the connection members 30 is one less than the number of the electric heating plates 20. Likewise, a plurality of connection members 30 are provided between the adjacent electric heating plates 20, and the connection members 30 are used to electrically connect the adjacent electric heating plates 20. When the number of the electric heating plates 20 is two or the number of the electric heating plates 20 is multiple, two electric heating plates 20 or two electric heating plates 20 are respectively positioned at two ends of the evaporator, and the wires do not need to extend to the inside of the evaporator to be connected with the electric heating plates 20, so that convenience of wire connection is ensured.

Optionally, the number of the connecting pieces 30 is two more than the number of the electric heating plates 20, the plurality of connecting pieces 30 includes a first connecting piece connected to the electric heating plate 20 closest to the first end of the evaporator and extending toward the first end of the evaporator, and a second connecting piece connected to the electric heating plate 20 closest to the second end of the evaporator and extending toward the second end of the evaporator.

Optionally, the surface of the electric heating plate 20 is coated with a first insulating coating.

By adopting the evaporator for the air conditioner provided by the embodiment of the disclosure, the first insulating coating is arranged on the wall surface of the electric heating sheet 20, so that the current of the electric heating sheet 20 can be prevented from being transmitted to an object in contact with the electric heating sheet 20, and the safety of the electric heating sheet 20 is improved.

Optionally, the first insulating coating has a thermal conductivity greater than or equal to 5W/m·k.

By adopting the evaporator for the air conditioner provided by the embodiment of the disclosure, the heat conductivity coefficient of the first insulating coating is greater than or equal to 5W/m.K, so that the first insulating coating can be ensured to have good heat conductivity, and the heat exchange efficiency of the electric heating plate 20 and air is ensured.

Specifically, the first insulating coating is disposed on the connecting end surface of the electric heating plate 20 and the refrigerant pipeline 10. In this way, on the one hand, the electric heating plate 20 can be prevented from conducting current to the refrigerant pipeline 10 connected with the electric heating plate 20, and on the other hand, the heat generated by the electric heating plate 20 can be transferred to the refrigerant pipeline 10, so that the heat exchange effect of the evaporator for the air conditioner is ensured.

The thermal conductivity of conventional heating elements is about fifteen percent. The electrical heating plate 20 made of superconducting alloy has ninety-five percent of thermal conductivity and thermal diffusivity, can instantaneously convert electric energy into heat energy to reach the required temperature, can instantaneously release the temperature to return to normal temperature, and has very high thermal efficiency. Due to the ultrahigh heat conductivity of the superconducting alloy heating element, the superconducting alloy heating element can instantly convert electric energy into heat energy, and then the air supply device is used for conveying hot air to a required space. For example: to send out the temperature of 90 ℃, only the superconducting alloy heater needs to be heated to 100 ℃. The traditional electric heater needs to be heated to 600 ℃ (usually only 400 ℃), the required electric energy is relatively increased, the heating time is also increased, and the required electric charge is increased. Thus, when the electric heating sheet 20 is electrically heated, a good heating effect can be achieved without setting the heating temperature of the electric heating sheet 20 too high.

Specifically, the heating temperature of the electric heating plate 20 is fifteen degrees higher than the temperature of the refrigerant line 10 when the evaporator is in heating operation. Thus, the heat transferred from the electric heating plate 20 to the refrigerant can be effectively reduced while the heating effect of the evaporator is ensured, and the influence of the electric heating plate 20 on the temperature of the refrigerant is reduced.

Through setting up electric heating plate 20 in series, can reduce electric heating plate 20's the connection degree of difficulty effectively, promote the installation convenience.
