Embodiment 1

[0020] Such as figure 1 The shown cleaning device applied to the condenser of an air conditioner includes a high-pressure air source 1, a vortex tube 2, a flexible pipeline 3, a nozzle array 4, a controller 5, a dirt sensor 6, an ambient temperature sensor 7, a hot gas end regulating valve 8, Pressure regulating valve 9, stepping motor 10, transmission mechanism 11, slider 12, guide rail 13, air conditioning condenser 14, cooling and heating proportional regulating valve 20, high-pressure air source 1 is maintained by the air conditioner through the interface set in the outdoor unit shell of the air conditioner The air compressor carried by the technician is provided. The high-pressure air source 1 enters the vortex tube 2, and separates the cold and hot air flows in the vortex tube 2. The temperature, pressure and flow rate of the pressure air at the cold and hot ends of the vortex tube 2 pass through the hot air The end regulating valve 8 and the pressure regulating valve 9 re...

Embodiment 2

[0022] Such as figure 2 The shown cleaning device applied to the vehicle cooling system includes a high-pressure air source 1, a vortex tube 2, a flexible pipe 3, a nozzle array 4, a controller 5, a dirt sensor 6, an ambient temperature sensor 7, a hot gas end regulating valve 8, Pressure regulating valve 9, stepping motor 10, transmission mechanism 11, air compressor 15, air source 16, rotating shaft 17, radiator 18 and intercooler 19. The vehicle cooling system is composed of radiator 18 and intercooler 19. The compressor 15 is powered by a vehicle engine or a turbine that uses vehicle exhaust energy. The air compressor 15 compresses air from an air source 16 as a high-pressure air source 1 and supplies it to the vortex tube 2. The high-pressure air source 1 enters the vortex tube 2 and is connected to the vortex tube 2. The temperature, pressure and flow rate of the cold end pressure air of the vortex tube 2 are controlled by the hot end regulating valve 8 and the pressure ...

Abstract

The invention relates to a cleaning device of a heat exchanger. The cleaning device of the heat exchanger comprises a high pressure air source, a vortex tube, a flexible tube, a nozzle array, a controller, a dirt sensor, an ambient temperature sensor, a hot-air end regulating valve, a pressure regulating valve, a stepper motor, a transmission mechanism and a hot and cold proportional regulating valve. The cleaning device of the heat exchanger utilizes the vortex tube to obtain temperature changeable pressure air and can automatically work on line. The cleaning device of the heat exchanger utilizes the pressure air for cleaning, the cleaning is easy to perform, and secondary pollution is not prone to occurring. Compared with water, the pressure air is easier to obtain. The temperature changeable pressure air can be used for achieving temperature changeable cleaning to remove dirt with adhesive force. The vortex tube which is used for the cleaning device is simple, convenient and low in cost. The cleaning can be performed on line, the heat exchanger does not need to stop working, and the high efficiency is obtained. The defects of cumbersome steps, disassembly necessary, structurally-damaged proneness of the manual cleaning are overcome. The cleaning of the heat exchanger through automatic procedures is achieved, the performance of the heat exchanger is improved, and the energy is saved. The cleaning device of the heat exchanger can be applied to air heat exchangers in the industrial fields and the civilian fields, such as air conditioner condensers and vehicle cooling systems.

Description

Technical field [0001] The invention relates to a heat exchanger cleaning device, in particular to an online variable temperature cleaning device without intermittent operation of the heat exchanger. Background technique [0002] Heat exchangers often use air to exchange heat and need to be exposed to work in the air. They are widely used in civil, industrial and other fields, such as air-conditioning condensers, vehicle cooling systems, computer cooling systems, etc., mud, dirt, and dust in the air , Floating objects will enter the heat exchanger gap and accumulate in the heat exchanger fins, reducing the heat exchange capacity, wasting energy and shortening the life of the system. Take the air-cooled heat dissipation system directly exposed to the outdoors in the vehicle cooling system as an example. The dirt that enters from the grille during driving can easily adhere to the radiator, especially in spring and autumn, some poplar catkins, catkins, leaves and other debris are fl...
