A threaded cylinder is fixedly installed on the end of the mounting frame, and a threaded rod is threadedly connected to the threaded cylinder. The threaded rod is located at one end inside the mounting frame and is rotatably connected to the middle part of the extrusion block. By twisting the threaded rod to rotate in the threaded cylinder, the extrusion block will be pushed to slide along the inner wall of the sliding groove, and then the brackets on both sides will be squeezed and clamped to the outside of the condenser body, thereby facilitating installation and disassembly.

[0006] As an optimization, the lifting assembly includes a servo motor fixedly installed on the top of the bracket, a lifting block is slidably connected inside the bracket, a screw is fixedly installed on one end of the output shaft of the servo motor, a roller is rotatably connected to the middle of the lifting block, a gear is fixedly installed on one end of the roller that passes through the lifting block, and a rack plate is fixedly installed at the corresponding gear inside the bracket.

[0007] As an optimization, the lifting block is threadedly sleeved on the outside of the screw, and the gear and rack plate are meshingly connected. By starting the servo motor to drive the screw to rotate, the lifting block will be driven to lift and lower inside the bracket, and the gear will be driven to roll along the lifting block, so that the roller can rotate while being lifted and lowered.

[0011] The beneficial effects of the utility model are:

[0012] 1. The HVAC replaces the heater core heating structure with a condenser. By replacing the heater core with the condenser, the refrigerant in the condenser runs in reverse, causing the refrigerant to condense and release hot air to pass through, thus playing a heating role.

[0013] 2. The HVAC replaces the heater core heating structure with a condenser. By starting the servo motor to drive the screw to rotate, the lifting block will be driven to rise and fall, and the gear will be driven to roll along the rack plate, which will cause the roller to rotate while moving up and down, and then drive the spring and the brush on the outside of the counterweight block to clean the impurities between the outer fins of the condenser. Since the counterweight block has its own weight and the spring itself has elasticity, the brush will shake when it rotates, which can improve the cleaning effect and avoid the accumulation of too many impurities affecting the heating effect.

A threaded cylinder is fixedly installed at the end of the mounting frame 8. A threaded rod 11 is threadedly connected to the threaded cylinder. The threaded rod 11 is located at one end inside the mounting frame 8 and is rotatably connected to the middle of the extrusion block 10. By twisting the threaded rod 11 and rotating it in the threaded cylinder, the extrusion block 10 will be pushed to slide along the inner wall of the slide groove 9, and then the brackets 4 on both sides will be squeezed and clamped on the outside of the condenser body 2, thereby facilitating installation and disassembly.

[0025] See also Figure 5The lifting assembly 6 includes a servo motor 12 fixedly installed on the top of the bracket 4, a lifting block 13 is slidably connected inside the bracket 4, a screw 14 is fixedly installed on one end of the output shaft of the servo motor 12, the lifting block 13 is threadedly sleeved on the outside of the screw 14, a roller 15 is rotatably connected to the middle of the lifting block 13, a gear 16 is fixedly installed on one end of the roller 15 that passes through the lifting block 13, a rack plate 17 is fixedly installed at the corresponding gear 16 inside the bracket 4, the gear 16 and the rack plate 17 are meshed and connected, and the screw 14 is driven to rotate by starting the servo motor 12, which will drive the lifting block 13 to be lifted and lowered inside the bracket 4, and at the same time, the gear 16 will be driven to roll along the lifting block 13, so that the roller 15 can rotate while being lifted and lowered.

[0026] See also Figure 6-7 The cleaning brush assembly 7 includes a fixing ring 18 fixedly sleeved on the outer side of the rack plate 17, a threaded groove is provided on the outer side of the fixing ring 18, and a fastening bolt 19 is detachably installed on the outer side of the fixing ring 18. The fastening bolt 19 is threadedly inserted in the threaded groove and can be installed and disassembled by twisting, which is convenient for replacement and maintenance;

[0027] See also Figure 6-7 A spring 20 is fixedly installed on the outside of the fastening bolt 19, and a counterweight 21 is fixedly installed on the end of the spring 20 away from the fastening bolt 19. The counterweight 21 is made of solid rubber. Brushes 22 are arranged on the outside of the spring 20 and the counterweight 21. The brush 22 on the outside of the spring 20 is spirally arranged around the trajectory of the spring 20. The rotation of the rack plate 17 will drive the spring 20 to rotate. Under the action of the deadweight of the counterweight 21, the spring 20 will shake, thereby improving the cleaning effect of impurities in the gap on the outside of the condenser.

[0028] During use, the refrigerant in the condenser first runs in reverse, causing the refrigerant to condense and release hot air to pass through to achieve a heating effect. After long-term use, a large amount of impurities will accumulate and adhere to the outer surface of the condenser, which will affect the heat dissipation effect of the condenser. At this time, starting the servo motor 12 will drive the screw 14 to rotate, so the lifting block 13 will be moved up and down, and at the same time, the gear 16 will be driven to roll along the lifting block 13, which will cause the roller 15 to rotate while moving up and down, and then drive the spring 20 and the counterweight block 21 to move up and down while rotating, so that the gap between the outer fins of the condenser can be cleaned by the brush 22, and the brush 22 will vibrate when rotating due to the deadweight of the counterweight block 21 and the elasticity of the spring 20 itself, thereby improving the cleaning effect.

[0029] To summarize, the HVAC replaces the heater core heating structure with a condenser. By replacing the heater core with the condenser, the refrigerant in the condenser runs in reverse, causing the refrigerant to condense and release hot air to pass through, thereby achieving heating. This can replace the heater core heating structure and does not require separate heating water. It can be widely used in electric vehicles and can generate heat through the refrigerant, thereby achieving energy-saving effect.

[0030] By starting the servo motor 12 to drive the screw 14 to rotate, the lifting block 13 will be driven to rise and fall, and the gear 16 will be driven to roll along the rack plate 17, so that the roller 15 will rotate while moving up and down, and the spring 20 and the brush 22 on the outside of the counterweight block 21 will be driven to clean the impurities between the outer fins of the condenser. Since the counterweight block 21 has its own weight and the spring 20 has its own elasticity, the brush 22 will shake when rotating, which can improve the cleaning effect, thereby avoiding the accumulation of too many impurities affecting the heating effect.
