[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figure 1-5 The utility model provides a technical solution: a solar heat exchange device for food processing, comprising an outer warehouse 1, a water inlet 3 is fixedly installed on the left side of the outer warehouse 1, a water outlet 4 is fixedly installed on the right side of the outer warehouse 1, a plurality of dining bowls 2 are placed above the outer warehouse 1, a first water tank 7 is fixedly installed on the left side of the inner part of the outer warehouse 1, a second water tank 8 is fixedly installed on the right side of the inner part of the outer warehouse 1, and a plurality of baffles 6 are fixedly connected to the inner part of the outer warehouse 1.
[0026] When in use, the water heated by solar heat conduction enters the first water tank 7 from the water inlet 3, and then enters the second water tank 8 through the pipe. After the heat is transferred in the outer compartment (1), the pre-prepared dishes placed in the dining bowl 2 are kept warm, and finally flow out from the water outlet 4.
[0027] The first water tank 7 has a first left chamber 14 and a first right chamber 15. The first left chamber 14 is fixedly connected to a plurality of third serpentine tubes 12 and a plurality of fourth serpentine tubes 13. The first right chamber 15 is fixedly connected to the water inlet 3. The first right chamber 15 is fixedly connected to a plurality of first serpentine tubes 10 and second serpentine tubes 11. The second water tank 8 has a second left chamber 16 and a second right chamber 17. The second left chamber 16 is fixedly connected to the fourth serpentine tube 13. The second left chamber 16 is fixedly connected to the water outlet 4. The second right chamber 17 is fixedly connected to the first serpentine tube 10, the second serpentine tube 11, and the third serpentine tube 12.
[0028] During operation, water heated by solar heat conduction flows from the water inlet 3 into the first right chamber 15, and then, under the action of water pressure, flows into the first serpentine tube 10 and the second serpentine tube 11, then into the second right chamber 17, and then into the third serpentine tube 12, and then into the first left chamber 14. Under the action of water pressure, the hot water is pressed into the fourth serpentine tube 13, and then to the second left chamber 16, and finally flows out from the water outlet 4. The hot water flows back and forth between the various pipes, transferring heat to the hot water in the outer compartment, thereby achieving heat preservation of the pre-prepared dishes.
[0029] Handles are fixedly installed at both the front and rear ends of the dining bowl 2 to facilitate staff to take the dining bowl 2.
[0030] A plurality of heat conducting sheets 9 are fixedly connected to the upper surface of the first serpentine tube 10 to improve the heat conduction efficiency and thus improve the heat preservation performance.
[0031] A partition 5 is fixedly installed in the outer bin 1, and a plurality of diversion holes are opened on the partition 5 to separate the bottom pipe from the upper layer. In order to prevent the pipe from being damaged, the backflow holes can guide the water in the lower layer of the outer bin 1 to the upper layer, thereby keeping the pre-prepared dishes warm.
[0032] The surface of the outer compartment 1 is fixedly connected with a heat-insulating layer to reduce heat dissipation and improve heat-insulating performance.
[0033] A plurality of sealing cover plates are fixedly mounted on the upper sides of the first water tank 7 and the second water tank 8 .
[0034] Working Principle: During use, water heated by solar heat conduction flows from the water inlet 3 into the first right chamber 15. Under the action of water pressure, it flows into the first serpentine tube 10 and the second serpentine tube 11, then into the second right chamber 17, then into the third serpentine tube 12, and finally into the first left chamber 14. Under the action of water pressure, the hot water is forced into the fourth serpentine tube 13, then into the second left chamber 16, and finally out of the water outlet 4. The hot water flows back and forth between the various pipes, transferring heat to the hot water in the outer chamber. The serpentine design of the pipes greatly increases the contact area between the pipes and the water in the outer chamber, thereby improving heat conduction efficiency. The heat conducting plate 9 fixed to the first serpentine tube 10 also improves heat conduction efficiency. After a period of time, the heated water in the bottom layer of the outer chamber flows to the upper layer through the diversion holes in the partition 5. Then, the staff will place the meal bowl 2 containing the pre-prepared food on the outer chamber 1, thereby keeping the pre-prepared food warm.
