Embodiment 2
[0092] As an optimization scheme of Embodiment 1, such as figure 1 , 2 , 3,
[0093] The transmission structure 400 also includes
[0094] The copper pipe 470 is arranged in the cooling chamber 120 through the positioning plate 471, and the part of the air inlet pipe 121 extending into the cooling chamber 120 is wound around the outer wall of the copper pipe 470 in a serpentine shape;
[0095] Outlet pipe 462, one end is connected to the water outlet end of water pump 461, the other end runs through the side wall of cooling chamber 120 and is connected to one end of copper pipe 470;
[0096] One end of the connecting pipe 480 is connected to the end of the copper pipe 470 away from the water outlet pipe 462, and the other end extends through the partition 130 and the side wall of the cooling chamber 120 into the heat insulation gap;
[0097] One end of the hose 490 is connected to the connecting pipe 480 in the heat insulation gap 490 , and the other end passes through the ...
Embodiment 3
[0100] As an optimization scheme of Embodiment 1, such as figure 2 , 3 , 4, 5,
[0101] The transmission structure 400 also includes
[0102] The insulation pipe 414 is arranged in the heat insulation gap in a serpentine shape. One end of the insulation pipe 414 runs through the side wall of the heat insulation board 300 and is connected to the drain pipe 412, and the other end of the heat insulation pipe 414 runs through the side wall of the heat insulation board 300 and the drain pipe 412. The heating box 420 is connected, and the connection between the insulation pipe 414 and the drain pipe 412 is located between the first solenoid valve 413 and the water outlet of the solar water heater 410 , and the insulation pipe 414 is provided with a second solenoid valve 415 .
[0103] This embodiment is implemented in such a way that when the temperature sensed by the temperature sensor 510 is lower than the minimum set value at night 20-5 o'clock in the morning, the first solenoid...
Embodiment 4
[0105] As the optimization scheme of embodiment three, such as figure 1 , 6 ,
[0106] A baffle 310 is provided at the open end of the front end of the heat insulation gap, and the baffle 310 is connected with the rotating cover 200 and the heat insulation board 300, and the inner side wall of the baffle 310 is in sliding contact with the outer wall of the electrical cabinet 100;
[0107] The second heat dissipation net 301 is arranged on the heat insulation board 300 and is used to discharge the air in the heat insulation gap.
[0108] This embodiment is implemented in such a way that the front opening of the heat insulation gap is sealed by the provided baffle plate 310, so that when the heat is kept warm at night, the outflow of a large amount of heat energy in the heat insulation gap can be reduced and the heat preservation effect can be improved; wherein the second The cooling net 301 is used for cooling and exhausting during the day.
[0109] As a further optimization...
