The temperature of the heating medium is not necessarily higher than the temperature of the cooling medium, for example, the temperature of the heating medium at the heating medium inlet 13 is higher than the temperature of the cooling medium at the cooling medium inlet 11, so that heat exchange can be smoothly performed. After the heat exchange is completed, the temperature of the heating medium at the heating medium outlet 14 may be higher than the temperature of the cooling medium at the cooling medium outlet 12, and the temperature of the heating medium at the heating medium outlet 14 may be lower than the temperature of the cooling medium at the cooling medium outlet 12.

For example, the electronic control module 231 is disposed outside the housing 24, and when the thermal energy recycling device 100 is operated, the electronic control module 231 communicates with the heating member 232 so that the heating member 232 converts electric energy into thermal energy. When the heat recycling apparatus 100 is not in operation, the electronic control module 231 is disconnected from the heating member 232. A plurality of heating elements 232 are spaced apart within the cavity.

The heating member 232 is disposed adjacent to the heating box inlet 21, and the heating medium enters the cavity from the heating box inlet 21 after heat exchange, and the heating member 232 is used for heating the heating medium to raise the temperature, so that heat exchange of the next round can be performed.

For example, the heating medium is water or steam, the first section 244 is conical, the second section 245 is cylindrical, and the third section 246 is inverted conical.

The plurality of heating elements 232 are all disposed within the third section 246, or a portion of the heating elements 232 are disposed within the third section 246 and another portion of the heating elements 232 are disposed within the second section 245. The water in the heating box 2 is gathered in the third section 246, the heating element 232 heats and evaporates the water to form water vapor, the water vapor flows upwards to gather in the first section 244 and flows out of the heating box outlet 22 and then enters the heating medium channel in the machine body 1, the water vapor is cooled to become water vapor after heat exchange, and the water vapor flows out of the heating medium outlet 14 and then enters the third section 246 from the heating box inlet 21 to start the cycle of the next round.

In the heat energy recycling device 100 according to the embodiment of the present utility model, the cross-sectional area of the third section 246 gradually decreases from top to bottom, so that water flows can be collected in the third section 246, and the heating element 232 can heat the water. The cross-sectional area of the first section 244 is gradually increased from top to bottom, so that water vapor can be accumulated in the first section 244, and can flow out of the heating box outlet 22 conveniently, thereby improving the working efficiency of the heating box 2 and further improving the working efficiency of the heat energy recycling device 100.

Alternatively, the preset value is 95-100 degrees, such as 95 degrees, 98 degrees, or 100 degrees.

Therefore, the heat energy recycling device 100 of the embodiment of the utility model utilizes the temperature sensor and the controller, so that the operation of the heating assembly 23 can be automatically controlled, and the heating assembly 23 can be automatically started when the water temperature is lower than the preset value, so that the heat medium in the heating box 2 is always kept at the required temperature, the refrigerant can be timely heated, and the working efficiency of the heat energy recycling device 100 is improved.

When the heat energy recycling device 100 works, the water vapor entering from the heat medium inlet 13 enters the air dispersing cylinder 16, is diffused towards the through holes, and then exchanges heat with the refrigerant in the spiral tube 15 when passing through the spiral tube 15.

The water vapor transfers heat to the refrigerant, cools to form water drops, falls on the bottom of the machine body 1, gathers into water flow, and flows out from the heat medium outlet 14. Alternatively, after the heat is transferred to the refrigerant, the water vapor gradually flows downward while maintaining the form of the water vapor, and then flows out of the heat medium outlet 14.

It will be appreciated that the heat sink, the through holes in the heat sink and the inner peripheral wall of the body 1 together define a heat medium passage.

In other embodiments, the outer peripheral sides of the first connection pipe 3 and the second connection pipe 4 are each provided with an insulating layer (not shown in the drawings). Thereby, heat loss of the fluid in the first connection pipe 3 and the second connection pipe 4 can be reduced.
