Description

Technical Field

[0001] This utility model belongs to the field of heat exchangers, and particularly relates to a heat exchanger for heat recovery. Background Technology

[0002] Solar photovoltaic panels are a high-efficiency energy technology that converts solar energy into electrical energy. With increasing environmental awareness and the promotion of renewable energy policies, solar photovoltaic panels are playing an increasingly important role in human life.

[0003] However, absorbing heat causes the solar photovoltaic panel itself to be in a high-temperature state, which leads to a short service life of the solar photovoltaic panel. In addition, this heat cannot be used, resulting in the loss of some energy. Therefore, it is necessary to design a technical solution that can absorb this heat and improve the service life. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a heat exchanger for heat recovery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat exchanger for heat recovery includes several heat exchange tubes arranged in parallel to form a plate-like structure. Both ends of the heat exchange tubes are connected to a manifold, and refrigerant flows through the heat exchange tubes and the manifold.

[0007] In the heat exchanger for heat recovery described above, the heat exchange tube is flat and the contact surface of the heat exchange tube for heat exchange is planar.

[0008] In the heat exchanger for heat recovery described above, each end of the heat exchange tube is provided with a raised curved section, and the lower end of the raised curved section is connected to the manifold.

[0009] In the heat exchanger for heat recovery described above, the heat exchange tubes and manifolds are made of aluminum alloy.

[0010] In the heat exchanger for heat recovery described above, the width of the heat exchange tube is 80 mm, and the distance between two adjacent heat exchange tubes is 5 mm.

[0011] The heat exchanger for heat recovery described above also includes a photovoltaic solar panel, wherein the heat exchange tube is bonded to the surface of the photovoltaic solar panel.

[0012] In the aforementioned heat exchanger for heat recovery, several heat exchange tubes are provided with flat tube bends to form a placement cavity between them and a photovoltaic solar panel. The photovoltaic solar panel is connected to a cable connector, which is located inside the placement cavity and has a connecting wire extending out from the placement cavity.

[0013] In the heat exchanger for heat recovery described above, the two heat exchange tubes in the middle and the heat exchange tubes on both sides are provided with flat tube bends. The cable connector can be set in the flat tube bends of the two heat exchange tubes in the middle, and the two ends of the connecting wire pass through the flat tube bends of the heat exchange tubes on both sides.

[0014] In the heat exchanger for heat recovery described above, the manifold is provided with a threaded joint for the inlet and outlet of refrigerant liquid.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. The heat exchanger can absorb heat, and the plate-like structure formed by several heat exchange tubes placed side by side increases the heat exchange area and improves the heat exchange efficiency. The parallel placement of several heat exchange tubes reduces gaps, which can prevent insufficient heat recovery and fully absorb the heat to improve the battery's lifespan.

[0017] 2. During the heat exchange process, the outer surface of the heat exchange tube comes into contact with the solar panel. Compared with round tubes, flat tubes can increase the contact area between the heat exchange tube and the solar panel, thereby improving the heat exchange capacity and efficiency.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a heat exchanger for heat recovery, combined with Figure 1-4 As shown, it includes several heat exchange tubes 10, which are arranged in parallel to form a plate-like structure. The two ends of each heat exchange tube 10 are connected to a manifold 11, and refrigerant flows through the heat exchange tubes 10 and the manifold 11.

[0025] In this embodiment, heat can be absorbed by the heat exchanger, and the heat exchange area is increased and the heat exchange efficiency is improved by the plate-like structure formed by several heat exchange tubes 10 arranged in parallel. The arrangement of several heat exchange tubes 10 in parallel reduces gaps, which can prevent insufficient heat recovery and fully absorb the heat to improve the battery's service life.

[0026] The heat exchange tube 10 is in the shape of a flat tube, and the contact surface of the heat exchange tube 10 used for heat exchange is planar.

[0027] In this embodiment, during the heat exchange process, the outer surface of the heat exchange tube 10 comes into contact with the solar panel. Compared with a round tube, a flat tube can increase the contact area between the heat exchange tube 10 and the solar panel, thereby improving the heat exchange capacity and efficiency.

[0028] The heat exchange tube 10 has a raised curved section 12 at each end, and the lower end of the raised curved section 12 is connected to the manifold 11.

[0029] In this embodiment, the heat exchange tube 10 is in contact with the solar panel during heat exchange. Therefore, by raising the curved section 12, the collector tube 11 is prevented from contacting the solar panel plane, which would otherwise cause the heat exchange tube 10 to not fit well with the solar panel.

[0030] The heat exchange tube 10 and the manifold 11 are made of aluminum alloy.

[0031] In this embodiment, the use of aluminum alloy makes the entire heat exchanger lightweight and easy to install and transport.

[0032] The width of the heat exchange tube 10 is 80mm, and the distance between two adjacent heat exchange tubes 10 is 5mm.

[0033] It also includes a photovoltaic solar panel 13, wherein the heat exchange tube 10 is bonded to the surface of the photovoltaic solar panel 13.

[0034] Several heat exchange tubes 10 are provided with flat tube bending sections 14, which form a placement cavity between the tubes and the photovoltaic solar panel 13. The photovoltaic solar panel 13 is connected to a cable connector 15, which is located inside the placement cavity and has a connecting wire extending out from the cavity.

[0035] Placing the cable connector 15 and the connecting wire inside the cavity formed by the bend in the flat tube 14 can effectively protect the cable connector 15 and the connecting wire and improve their service life.

[0036] Flat tube bends 14 are provided on the two heat exchange tubes 10 in the middle and the heat exchange tubes 10 on both sides. Cable connectors 15 can be set in the flat tube bends 14 of the two heat exchange tubes 10 in the middle, and the two ends of the connecting wire pass through the flat tube bends 14 on the heat exchange tubes 10 on both sides.

[0037] The manifold 11 is provided with a threaded connector 16 for refrigerant liquid inlet and outlet.

[0038] In this embodiment, the refrigerant enters and exits through the threaded connector 16 for the next heat exchange.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0040] Although this article frequently uses terms such as heat exchange tube 10, manifold 11, raised curved section 12, photovoltaic solar panel 13, flat tube bending section 14, cable joint 15, and threaded joint 16, these terms are used merely to more conveniently describe and explain the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
