Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1-4 An air compressor waste heat recovery device includes an air compressor body 1, a partition 6 fixed to the top of the inner wall of the air compressor body 1, an air outlet 15 of the air compressor body 1 extending above the partition 6 and connected to a serpentine pipe 14, one end of the serpentine pipe 14 extending to the outside of the air compressor body 1, a water storage chamber 8 in the air compressor body 1 above the partition 6, the serpentine pipe 14 located in the water storage chamber 8, a water supply component installed on one side of the outer wall of the water storage chamber 8, a top cover 9 at the top of the water storage chamber 8, an air-cooling component installed on the top cover 9, heat-conducting fins 16 evenly spaced at the top of the partition 6 below the serpentine pipe 14, each heat-conducting fin 16 having a through hole 19, and a control panel 13 fixed to the outer wall of the air compressor body 1.

[0022] The water supply assembly includes a water pump 12 fixed to the outer wall of one side of the water storage chamber 8. The pump 12 is connected to a pump pipe 11 at the pumping end and to an outlet pipe 10 at the outlet end. One end of the outlet pipe 10 is connected to the top of one side of the water storage chamber 8. One end of the pump pipe 11 is connected to the water supply pipe. The pump 12 is electrically connected to the control panel 13.

[0023] A connecting pipe 2 is fixed to the top of the other side of the water storage chamber 8. One end of the connecting pipe 2 is connected to a three-way valve 3. The other two ends of the three-way valve 3 are connected to a drain pipe 4 and an exhaust pipe 5, respectively. One end of the drain pipe 4 is connected to the water storage tank. A drain valve 17 is installed at the bottom of one side of the water storage chamber 8.

[0024] The heat from the air compressor body 1 is absorbed by the baffle 6 and the heat-conducting fins 16. The gas discharged from the air compressor body 1 is absorbed by the serpentine tube 14. Water is slowly supplied to the water storage chamber 8 through the water pump 12. When the water level rises to the limit position, the water is discharged through the connecting pipe 2, the three-way valve 3 and the drain pipe 4 to achieve water level balance. The heat absorbed by the baffle 6, the heat-conducting fins 16 and the serpentine tube 14 is carried away by the water, realizing heat energy recovery and thus producing hot water.

[0025] Example 2 is an optimization based on Example 1, specifically:

[0027] When hot air is needed instead of hot water, turn off the water pump 12, open the drain valve 17 to drain the water from the water storage chamber 8, turn on the fan 18, and switch the three-way valve 3 to connect the connecting pipe 2 and the exhaust pipe 5. Cold air from the outside enters the water storage chamber 8 to cool the partition 6, the heat-conducting fins 16 and the serpentine tube 14. Hot air is discharged from the exhaust pipe 5 for use.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
