Detailed ways

    The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 2, a device for recovering and reusing the exhaust energy of an air-conditioning external unit includes a Laval nozzle 3, a transmission shaft wind turbine 5, and a heating pipe 6; the Laval nozzle 3 is placed on a bracket 4, the height of the bracket 4 can be adjusted, and the air-conditioning external unit 2 is placed on the base 1, so that the nozzle of the Laval nozzle 3 is aligned with the exhaust port of the air-conditioning external unit 2, that is, the Laval nozzle The axis of 3 is collinear with the axis of the exhaust port of the air conditioner external unit 2, and the distance between the two is D; the spiral heat receiving pipe 6 is arranged on the inner wall of the Laval nozzle 3, and is The heat pipes 6 are unevenly distributed in the Laval nozzle 3, and the heat pipes are arranged more densely near the outlet area of the air conditioner external unit. The heat receiving pipe 6 is connected with the water storage tank 7, and the water storage tank 7 is placed on the supporting base 8, and the supporting base 8 plays a stabilizing and supporting role. The outer wall of the water storage tank 7 is connected with a cold water inlet pipe 9 and a hot water outlet pipe 10 to realize the functions of water flow in and out and discharge. The cold water in the heat receiving pipe 6 is gradually circulated and heated by the hot air flow discharged from the air conditioner external unit 2 . As shown in Figure 2, the drive shaft wind turbine 5 is in an "S" shape and placed at the throat position in the Laval nozzle 3, but the drive shaft wind turbine 5 is not in contact with the inner wall of the Laval nozzle 3 , while not in contact with the heat pipe 6; the middle position of the transmission shaft wind turbine 5 is fixedly connected to one end of the transmission shaft 11; the throat position of the Laval nozzle 3 has the largest air velocity, and the transmission shaft wind turbine 5 Under the action of air kinetic energy, the transmission shaft wind turbine 5 can rotate and drive the transmission shaft 11 to rotate; the other end of the transmission shaft 11 passes through the hole at the bottom of the throat of the Laval nozzle 3 and connects with the bevel gear box 12 The bevel gear box 12 is connected with the generator 13 to drive the generator 13 to generate electricity, so as to achieve the purpose of recovering and reusing the kinetic energy of the exhaust gas.

The distance between the Laval nozzle 3 and the exhaust port of the air conditioner external unit 2 is D, which can be adjusted as required;

The distribution of the heat receiving pipes 6 is uneven, the distribution of the heat receiving pipes 6 at one end close to the exhaust port of the air conditioner external unit 2 is relatively dense, and the distribution of the heat receiving pipes 6 at the end far away from the exhaust port is relatively loose, which is beneficial to exhaust heat energy in summer Absorption.

In summer, due to the high heat of the exhaust gas near the exhaust port of the external unit of the air conditioner, there are unevenly distributed spiral heat-receiving tubes arranged on the inner wall of the Laval nozzle.
