Problems solved by technology
In summer, when the temperature rises, the pressure of the high-pressure end also rises, so the phenomenon of poor heat dissipation and poor cooling effect occurs. If the cooling effect is not good, if the set temperature cannot be reached, the compressor will not stop and work for a long time. , resulting in a further increase in the pressure at the high-pressure end, forming a vicious cycle, and the compressor generates fatigue and heat and damages the compressor, which will consume more fuel and affect the service life of the engine and air-conditioning system

The invention discloses an automatic spraying and auxiliary cooling device for an automotive air conditioner, and belongs to the field of the cooling device. The cooling device comprises a control branch and a water-jet pump branch which are connected in parallel with automotive accumulators, and further comprises a water spraying component. The control branch is connected in series with an ignition switch, an AC switch, a low-voltage protection switch, a low water switch, a coil circuit of a relay, a high-voltage switch and a high water switch, and the water-jet pump branch is connected in series with the output circuit of the relay and a water-jet pump; and the water spraying component mainly comprises a cold water collecting pipe of an evaporator, a water collecting tank, the water-jet pump, a water-jet pipe and spray heads, which are successively connected. The cooling device uses evaporator cold water discharged by the air conditioner as a cooling material to be sprayed on a condenser and the automatic spraying and auxiliary cooling device for the automotive air conditioner on a high-voltage pipe, the high voltage of the air conditioner can be lowered, and spraying water is vaporized to absorb the caloric of the condenser as latent heat of vaporization, so that double actions of accelerating heat dissipation and cleaning the condenser are obtained.
Description
technical field [0001] The invention relates to an auxiliary refrigeration device for an automobile air conditioner, in particular to an automatic spray auxiliary refrigeration device for an automobile air conditioner. Background technique [0002] At present, when the air conditioner is turned on in the car, it generally has poor heat dissipation and high pressure, which directly affects the comfort in the car, consumes electricity and fuel, makes noise, and pollutes the environment. Because the condenser of the car air conditioner relies on the fan to blow the air, and uses air cooling to reduce the temperature of the condenser. Dust on the surface leads to poor convection around it, which leads to poor cooling effect of the condenser, decreases the cooling efficiency of the air conditioner, increases fuel consumption, and ultimately reduces the reliability of the air conditioner or damages the compressor. And the pressure of the high-pressure pipe of the car is too high:...
