At this time, start the heat pump 11 to heat the waste heat inside the placement box 10, and check the temperature through the temperature measuring rod 13. When the temperature reaches the required usable temperature, it is displayed on the display 12, and finally cooperate with the electromagnetic valve 14 to open, and cooperate with the outlet pipe 15 to transport it out, thereby realizing the use of the heat energy provided by the low-grade waste heat.

The waste heat is then sent to the inside of the storage box 209 through the L-shaped tube 202, and checked with the temperature measuring rod 208 and the storage box 209. When the temperature is too high, the rubber plug 203 is then taken out from the inside of the air outlet 206 for cooling. When the temperature is too low, it is heated by a heat pump 210 to reach the temperature required for use. Finally, it is transported through the air outlet pipe 205, thereby solving the problem of heating or cooling waste heat in different temperature ranges, and then reaching the temperature in the required use range, and the operation is more convenient.
