Description

Technical Field

[0001] The present application relates to the technical field of heat exchange equipment, and in particular to a self-cooling energy box. Background Art

[0002] An air source heat pump is a device that uses the heat in the air to generate heat. Its working principle is based on the reverse Carnot cycle. Simply put, it achieves heat transfer through components such as compressors, evaporators, condensers, and expansion valves. In the evaporator, the refrigerant absorbs low-grade heat in the air and evaporates, turning into a gas. Then, the gaseous refrigerant is compressed by the compressor, and the temperature and pressure increase. Next, the high-temperature and high-pressure refrigerant enters the condenser, where the refrigerant releases heat to the medium that needs to be heated (such as water or air) and condenses itself into a liquid. Finally, the liquid refrigerant is throttled and depressurized by the expansion valve, and enters the evaporator again to start the next cycle.

[0003] The energy box is a box that combines a heat pump system, a circulation system, water replenishment, power distribution, etc., and is mainly installed outdoors.

[0004] In summer, the energy box generates heat, causing the internal components to alarm and shut down, so it is necessary to add a self-cooling device to cool the energy box. Summary of the invention

[0005] In order to cool the energy box, the present application provides a self-cooling energy box.

[0006] The above technical objectives of this application are achieved through the following technical solutions: A self-cooling energy box comprises a box body, a compressor, a condenser and an expansion valve are arranged in the box body, an evaporator is arranged above the box body, two ends of the evaporator are respectively connected to the compressor and the expansion valve, a power distribution component is arranged in the box body, through holes are opened on opposite sides of the box body, an inlet fan and an outlet fan are respectively arranged in the two through holes, the inlet fan is used to blow the outside air into the box body, and the outlet fan is used to blow the air in the box body to the outside.

[0007] By adopting the above scheme, when the energy box needs to be cooled, the inlet fan and the outlet fan are started at the same time. The inlet fan is used to blow outside air into the energy box to exchange heat with the air inside the energy box. The outlet fan discharges the hot air in the energy box out of the energy box, speeding up the air flow inside the energy box, thereby speeding up the heat dissipation of the energy box, thereby cooling the energy box.

[0008] Optionally, a partition plate is provided in the box body, which separates the power distribution assembly from the compressor, the condenser and the expansion valve, and the inlet fan and the outlet fan are both located on the side of the partition plate where the power distribution assembly is provided.

[0009] By adopting the above solution, the heat-generating power distribution components are separated from the compressor, etc., so as to avoid the power distribution components heating up to the point that the compressor, condenser and expansion valve cannot work normally.

[0010] Optionally, a square frame is fixedly connected to the through hole on the side close to the outside. The inside of the square frame is hollow. A plurality of blades are connected inside the square frame. The plurality of blades are arranged in a linear array. One end of the blade is rotatably connected to the square frame. The other end of the blade is connected to a driving structure for driving the blade to rotate. When heat dissipation is not required, the plurality of blades will block the through hole.

[0011] By adopting the above scheme, blades are set to cover the through holes. When heat dissipation is performed, the driving structure drives the blades to rotate and open, so that gaps exist between adjacent blades, and air enters or is discharged from the heat dissipation box through these gaps. When heat dissipation is not required, the driving structure drives the blades to rotate so that multiple blades completely cover the through holes, thereby preventing dust and rainwater from entering the energy box and causing the internal parts to malfunction.

[0012] Optionally, the driving structure includes a driving cylinder, which is fixedly connected inside the frame, a piston rod of the driving cylinder is fixedly connected to a rack, and a blade is fixedly connected to a rotor gear, and the rack is meshed with multiple rotor gears at the same time.

[0013] By adopting the above solution, when the piston rod of the driving cylinder is extended or retracted, the driving cylinder drives the rack to move, and the rack drives the vane gear to rotate, thereby driving the vane plate to rotate, so that multiple vanes can rotate simultaneously.

[0014] Optionally, a temperature monitor for controlling the start-up of the inlet fan and the outlet fan is provided inside the box.

[0015] By adopting the above solution, when the temperature inside the energy box is too high, the temperature monitor can detect that the temperature inside the energy box is too high, thereby controlling the inlet fan and the outlet fan to turn on, thereby cooling the inside of the energy box. When the temperature inside the energy box drops to a specified temperature, the temperature monitor controls the inlet fan and the outlet fan to turn off, thereby reducing energy waste.

[0016] Optionally, a return pipe is provided inside the box body near the inlet fan, and a coolant is provided in the return pipe. A portion of the return pipe is spirally wound around one end of the evaporator near the expansion valve.

[0017] By adopting the above scheme, the gas that has just passed through the expansion valve is a low-temperature and low-pressure gas, and a return pipe is set to exchange heat with the pipe at one end of the evaporator close to the expansion valve, so as to cool the return pipe, so that the airflow blown into the energy box by the inlet fan exchanges heat with the return pipe, so that the temperature of the air blown into the energy box by the inlet fan is lower, thereby achieving a better cooling effect on the energy box.

[0018] Optionally, the refrigerant in the return pipe is difluoromethane.

[0019] By adopting the above scheme, difluoromethane has good thermodynamic properties and high refrigeration efficiency, which makes the heat conduction efficiency of the reflux pipeline higher.

[0020] Optionally, the return duct near the inlet fan is a return duct coiled in a serpentine shape.

[0021] By adopting the above solution, the contact area between the energy box blown by the inlet fan and the return duct is increased, so that the contact area between the air blown by the inlet fan and the return duct is increased, thereby making the heat exchange efficiency between the return duct and the air higher.

[0022] Optionally, the return pipe is connected to a pump structure for driving the flow of the medium inside the return pipe, the pump structure includes a drive box, both ends of the drive box are connected to the return pipe, a driving gear and a driven gear are rotatably connected inside the drive box, the driving gear is meshed with the driven gear, and the driving gear is connected to a power structure that drives the driving gear to rotate.

[0023] By adopting the above scheme, the power structure drives the main gear to rotate, and the main gear drives the driven gear to rotate. Since the main gear and the driven gear are meshed, the gap between the driving gear and the driven gear is filled, and the coolant cannot pass between the driving gear and the driven gear. However, both the driving gear and the driven gear have gear teeth, so there are gaps between the driving gear and the driven gear and the side wall of the drive box, so that the coolant moves in these gaps, thereby realizing one-way drive of the coolant.

[0024] Optionally, the power structure includes a wheel rod, which is rotatably connected to the inside of the box, and the two ends of the wheel rod are respectively fixedly connected to the second bevel gear and the third bevel gear, the rotating shaft of the air inlet fan is fixedly connected to the first bevel gear, the first bevel gear and the second bevel gear are meshed, one end of the rotating shaft of the driving gear passes through the drive box and is fixedly connected to the fourth bevel gear, and the fourth bevel gear is meshed with the third bevel gear.

[0025] By adopting the above solution, when the air intake fan rotates, the air intake fan drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, thereby driving the wheel rod to rotate, the wheel rod drives the third bevel gear to rotate, the third bevel gear drives the fourth bevel gear to rotate, thereby driving the driving gear and the driven gear to rotate.

[0026] In summary, this application has the following technical effects: 1. By setting up an inlet fan and an outlet fan, the air flow in the energy box is increased, thereby increasing the heat dissipation of the energy box; 2. The blades are set to prevent external dust from entering the energy box when it is not dissipating heat; 3. The heat dissipation efficiency of the energy box is further improved by setting up a return pipe. BRIEF DESCRIPTION OF THE DRAWINGS

A temperature monitor 7 for controlling the start of the inlet fan 2 and the outlet fan 3 is provided inside the box body 1. When the temperature inside the energy box is too high, the temperature monitor 7 can detect that the temperature inside the energy box is too high, thereby controlling the inlet fan 2 and the outlet fan 3 to turn on, thereby cooling down the inside of the energy box. When the temperature inside the energy box drops to a specified temperature, the temperature monitor 7 controls the inlet fan 2 and the outlet fan 3 to turn off, thereby reducing energy waste.

The return pipe 71 is provided to perform heat exchange with the pipe at the end of the evaporator near the expansion valve, thereby cooling the return pipe 71, so that the airflow blown into the energy box by the inlet fan 2 performs heat exchange with the return pipe 71, so that the air temperature blown into the energy box by the inlet fan 2 is lower, thereby achieving a better cooling effect of the energy box.
