The heat absorption end of the heat pipe of the heating box part is of a linear structure. The reflectors are correspondingly positioned below the heat pipes of the heat storage box part one by one. The heat storage tank is provided with a plurality of cylindrical protrusions 75. The heat pipes of the heat storage box part penetrate through the cylindrical bulge through the end surface of the cylindrical bulge in a one-to-one correspondence manner and are inserted into the heat storage box. The heat pipes of the heat storage box part are hermetically connected with the heat storage box. The reflector is provided with a coupling ring 76.

When the reflector is used, the rack is reciprocated and translated to drive the gear ring outside the connecting ring portion to rotate forwards and reversely, so that the reflector rotates to keep facing the sun all the time. The extending direction of the rotating axis of the reflector is the same as the extending direction of the heat absorbing end of the heat pipe of the heat storage box part.

When baking is carried out, the hole cover opening and closing cylinder contracts to enable the hole cover to seal the observation hole, and at the moment, the driving head presses the driving rod to drive the valve plate to seal the air inlet channel. Open the light and observe through the through-hole when needing to observe the box inside.
When the transformer in the box body needs to be removed and the temperature is reduced, the hole cover opening and closing cylinder extends to drive the hole cover switch, at the moment, the pressing head loses the pressing effect on the driving rod, the valve is controlled to be opened under the effect of the valve opening spring, and the gas from the source output is input into the box body to discharge hot gas in the box body.
The process of loading and unloading the transformer comprises the following steps: the door plate is opened (the door plate is opened in a mode that three plates forming the door plate rotate by taking respective hinges as rotating shafts), after the door plate is opened, the upper end of the lower plate is supported on the ground 25, the lower end of the lower plate is connected to the bottom wall of the box body to form a feeding and discharging sliding slope, and the slope of the feeding sliding slope is below 30 degrees, namely the included angle between the left side surface 26 of the lower plate and the horizontal plane is smaller than or equal to 30 degrees. At the moment, the upper end of the lower plate and the lower end of the supporting leg are positioned on the same plane. The transformer is moved into and out of the tank by moving from the lower plate.
After the sun irradiates the heat absorption end of the heat pipe of the heat storage box part, heat is absorbed by the heat absorption end of the heat pipe of the heat storage box part and is dissipated from the heat dissipation end of the heat pipe of the heat storage box part, and therefore fluid in the heat storage box is heated. When the baking is needed, the circulating pump is started to enable the hot fluid in the heat storage tank to flow through the heat exchanger to circulate, and the hot fluid is used as a heat source for baking in the baking oven. The part of the sun which is irradiated away from the side of the heat absorption end of the heat pipe of the heat storage box part irradiates the reflector and is reflected back to the heat absorption end of the heat pipe of the heat storage box part by the reflector for utilization, thereby improving the utilization rate of solar energy. When the reflector driving mechanism is used, the rotating angular speed of the reflector is equal to the rotating angular speed of the sun with the reflector as the center, so that the reflector always keeps facing the sun, and poor heating effect caused by backlight is prevented.
