Description

Technical Field

[0001] The utility model relates to the field of high-voltage protection devices, in particular to a high-voltage protection device for air conditioners. Background Art

[0002] The air conditioner high pressure protection is a switch action for the air conditioner exhaust pressure that is generally higher than 3.5MPA. Its function is to prevent excessive refrigerant in the system and poor heat dissipation of the condenser, which may damage the compressor or burst the pipe. During normal operation of the equipment, these controllers are in a normal "sleeping" state and are rarely "active". However, the circuit

[0003] ——E circuit break or intermittent circuit break, they will play a role, thereby preventing the compressor from working. This protection device is directly applied to air-conditioning products. The equipment is the air-conditioning high-voltage switch, that is, the air-conditioning high-voltage protector.

[0004] The air conditioner high-pressure pressure protector is located in the high-pressure exhaust pipeline of the compressor and can monitor the exhaust pressure. The contacts of the controller are closed under normal circumstances. It is connected in series with the power relay or the contactor coil that controls the compressor. If the system exhaust pressure exceeds the predetermined range due to a fault (such as a condenser fan motor failure or a condenser airflow obstruction), it may cause overpressure, causing the controller contacts to jump open and shut down the compressor. This overpressure is caused by a condenser fan motor failure or a condenser airflow obstruction, so along with the increase in the air conditioning compressor pressure, the air conditioning compressor, condenser, etc. may not be able to dissipate heat normally.

[0005] Therefore, when the above-mentioned air-conditioning compressor becomes high-pressure due to a condenser fan motor failure or condenser airflow obstruction, the air-conditioning compressor, condenser, etc. will not be able to dissipate heat normally. An air-conditioning high-pressure protector can be designed to assist the air-conditioning compressor, etc. in accelerating heat dissipation. Utility Model Content

[0010] Preferably, the air cooling module also includes a ventilation net; a slot is provided on the outer wall of the protective cover and a ventilation net with a metal mesh structure is installed and fixed in the slot, the air inlet channel of the blower is connected to the ventilation net, the blower draws air from outside the protective cover through the ventilation net, and compresses and sends it out through high-speed rotating fan blades, and the high-speed air flow passes through the surfaces of the compressor and exhaust pipe to take away the working heat.

[0011] Preferably, the air supply module includes an air ring and air holes; the air ring is a hollow aluminum alloy metal ring and is mounted on the outside of the protector shell. 30 air holes are evenly spaced around the upper end of the outer wall of the air ring, and 60 air holes are evenly spaced around the side of the outer wall of the air ring. The high-speed air flow delivered into the air ring is evenly transported to the surroundings of the air ring through the ring-shaped air holes, covering a wide range.

[0012] Preferably, an air supply hose is connected to one side of the air ring, which passes through the holes on the protective cover and is connected to the air outlet channel of the blower.
