The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.
 Combine Figure 1 to Figure 3 As shown, this embodiment provides a temperature-adjustable solar heating device, comprising a heat preservation and heat absorption box body 1, a heating flow channel arranged in the heat preservation and heat absorption box body 1, and a heating flow channel arranged through The input port 11 and the output port 12 used for the heating medium to flow in and out, as well as the flow guide mechanism matched with the heating flow channel to form different heating path lengths, and the flow guide mechanism is connected with an external electric control device.
 Specifically, in this embodiment, a plurality of partitions 21 are arranged in parallel and spaced in the cavity of the heat preservation and heat absorption box 1, and both ends of the plurality of partitions 21 are respectively provided with the diversion mechanism, and The deflector mechanism includes a driving device 31 fastened to the end of the partition 21, and a deflector 32 fastened to the power output end of the driving device 31. When the driving device 31 drives the deflector When 32 rotates, the tail end of the deflector 32 is matched with the inner wall of the heat preservation and heat absorption box 1 or the side wall of the adjacent partition 21.
 In this embodiment, the heating medium is set to room temperature air, combined with figure 2 As shown, when the room temperature air flows into the heating channel along the input port 11, the guide mechanism provided at the end of the partition 21 can guide the room temperature air to bend and flow sequentially along the channels between adjacent partitions until the end The output is output from the output port 12. In this process, through the continuous absorption of the heat preservation and heat absorption box 1, the normal temperature air forms a longer heating path during the flow process, and finally a higher temperature heat is formed at the output port 12. Air, in order to achieve energy conversion; similarly, combine image 3 As shown, in order to change the temperature of the hot air at the output port 12, when the input of room temperature air is equal, the air guide mechanism provided at the end of the partition 21 can guide the room temperature air along the air flow between the partitions. Two adjacent channels bend and flow in sequence, and compared with the above-mentioned single-channel bend flow, the room temperature air forms a shorter heating path during the flow process, and finally forms a lower temperature hot air at the output port 12; in practical applications According to the parameters of the heat absorption of the heat preservation box, the air intake at the input port, and the temperature of the hot air at the output port that are actually detected by the electronic control device, the diversion mechanism can be further dynamically controlled in real time. That is, the rotation position of the baffle is dynamically changed to form a heating flow channel that matches the output temperature, and finally a different output temperature is obtained at the output port.
 In this embodiment, such as figure 2 with image 3 As shown, the rotation angle between the deflector 32 and the corresponding partition 21 is adjustable. In order to satisfy the diversion of room temperature air, in order to ensure that the room temperature air flowing in through the input port flows out from the gap between the deflector and the chamber wall, a sealing mechanism can be set at the gap to effectively solve the problem, or according to the heating channel Depending on the amount of air intake, the position of the deflector is changed in real time.
 In order to increase the heat absorption and heat preservation effect of the heat preservation and heat absorption box 1, in this embodiment, the heat preservation layer 13 is arranged on the outside of the heat absorption layer, and the heat absorption layer is arranged as a solar heat collecting plate; The top of the heat box 1 is provided with a solar light entrance, and the solar light entrance is provided as a laminated transparent glass plate 14 filled with inert gas. With this structural design, sunlight can pass through the laminated transparent glass plate 14 and enter the heat preservation and heat absorption box 1, so that the heat preservation and heat absorption box 1 can normally absorb heat through the heat absorption layer and can also pass through the heat preservation layer. 13 and laminated transparent glass plate 14 for heat preservation. In this embodiment, the heat preservation and heat absorption box 1 can be buried in an open area, and the laminated transparent glass plate 14 is flush with the buried surface, so as to receive more sunlight.
 In this embodiment, the input port 11 and the output port 12 are respectively connected to external devices. Preferably, the external device can be set as a lithium bromide absorption chiller (the lithium bromide aqueous solution of a lithium bromide absorption chiller has a high boiling point, so a higher heat source temperature is required for normal operation. At present, the temperature of the existing heat source medium can be normally cooled when the temperature exceeds 80°C. Crew). The lithium bromide absorption refrigerator is connected to the output port 12 to obtain a heat source, and then the heat energy can be converted into cold air by the lithium bromide absorption refrigerator. At the same time, the input port of the solar heater is connected to the outlet of the lithium bromide unit, and the waste heat is recovered for solar energy The heater circulates heating. Adopting the above-mentioned design method makes full use and conversion of solar energy, thereby achieving the purpose of energy saving and environmental protection. Preferably, the external device can also be set as a house fresh air ventilation system, the input port of the solar heater can be connected to an air filter to access natural air, and the output port can be connected to a fresh air unit to deliver fresh air that meets the indoor temperature requirements. In the room, it plays a role of natural ventilation with extremely low energy consumption.
