Embodiment 1

[0040] like figure 1 , figure 2 , Figure 5 to Figure 8As shown, the device of the present invention that uses ultrasonic vibration to suppress frosting on the evaporator includes an evaporator, and the evaporator includes a liquid pipe 3 (the liquid pipe 3 is a copper pipe or an aluminum pipe), and the liquid pipe 3 is connected with a finned tube in the form of an expansion tube. Sheet 2 (the connection method of the expansion tube can ensure that the perforation is an interference fit), the liquid tube 3 is connected with a vibration transmission plate, and the vibration transmission plate is preferably made of copper, aluminum or other metal alloys, mainly used for transmitting ultrasonic waves and High-frequency mechanical vibrations caused by ultrasonic mechanical effects. The vibration transmission plate includes a vibration receiving surface 1A, which is welded or glued on the liquid pipe 3, and a power ultrasonic transducer 4 is vertically and fixedly connected to ...

Embodiment 2

[0056] like image 3 and Figure 4 As shown, the differences between this embodiment and Embodiment 1 are:

[0057] The vibration-receiving surface 1A is not welded or glued together with the liquid pipe 3, and the vibration-transmitting plate also includes a vibration-transmitting surface 1B integrally arranged or connected with the vibration-receiving surface 1A. 1B is perpendicular to the vibration-receiving surface 1A and inserted between the fins 2; the vibration-transmitting surface 1B is provided with a mounting hole 1C for insertion on the liquid pipe 3, and the liquid pipe 3 passes through the The mounting hole is fixedly connected to the vibration transmitting surface 1B in the form of an expansion tube.

[0058] Among them, such as image 3 and Figure 4 As shown, the vibration-receiving surface 1A and the vibration-transmitting surface 1B of the vibration-transmitting plate form a T-shape or an inverted L-shape, and the thicknesses of the vibration-receiving su...

Abstract

The invention discloses a device for inhibiting frost formation of an evaporimeter by supersonic vibration. The device comprises the evaporimeter which comprises liquid tubes; the liquid tubes are connected with fins; the liquid tubes are connected with a vibration transfer plate; and the vibration transfer plate comprises a vibration bearing surface which is fixedly connected with a power ultrasonic transducer. The vibration of the power ultrasonic transducer is transferred to the fins through the vibration transfer plate and the liquid tubes, so that the supersonic vibration can be dispersed to the whole evaporimeter. Power ultrasonic waves are all distributed on the whole evaporimeter, early crystal growth can be disturbed by using mechanical vibration effect of power ultrasonic waves,and depending on the high accelerated speed and low amplitude action force, and the frost crystal is broken and falls off on the fins on which the frost crystal grows; therefore, the frost blockage between the fins is avoided. The device has a simple structure, is low in energy consumption, has a good frost formation effect and a good frost removal effect, and can inhibit and reduce the frost formation of the evaporimeter, achieve the effect of descaling the surface of the evaporimeter, and guarantee the normal heat exchange of the evaporimeter.

Description

technical field [0001] The invention relates to the technical field of defrosting of refrigeration equipment, in particular to a device for preventing and reducing frosting of an evaporator of refrigeration equipment by using ultrasonic waves. Background technique [0002] Frosting on the evaporators of air source heat pump air conditioners, air-cooled refrigerators, air coolers and other refrigeration equipment is a technical problem that plagues the refrigeration industry. Frosting on the surface of the evaporator on the air side of the heat pump will block the air channel of the evaporator, increase the air flow resistance and air pressure drop, reduce the air flow and increase the heat transfer resistance of the evaporator, thereby reducing the evaporation temperature and reducing the average temperature of the evaporator. The heat transfer coefficient seriously reduces the heat transfer efficiency of the evaporator. Refer to Table 1 for thermal conductivity comparison....
