Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to an eight-way valve. Background Art

[0002] At present, photovoltaic inverters in household photovoltaic energy storage mainly use natural cooling or air cooling to dissipate heat. The heat sink is large in size, high in cost, and has poor heat dissipation effect. The temperature of the photovoltaic inverter heat sink is high, and the electrical components work in high temperature for a long time, which shortens the service life of the photovoltaic inverter. High temperature also poses a safety hazard, so it is necessary to dissipate heat from the photovoltaic inverter.

[0003] Lithium batteries in household photovoltaic energy storage generate a lot of heat during the charging and discharging process. Overheating of lithium batteries can easily lead to battery failure or even explosion. Long-term overheating of lithium batteries will affect the service life of the batteries, so lithium batteries need to be cooled and dissipated. In some areas, the temperature is low all year round, and lithium batteries cannot be charged and discharged at low temperatures. Therefore, lithium batteries need to be heated at low temperatures to ensure their normal operation.

[0004] Traditional photovoltaic power generation systems require multiple valves to control multiple water channels separately when dissipating heat from battery packs and photovoltaic inverters and using the heat generated by the photovoltaic inverter to heat low-temperature lithium batteries when needed, resulting in the need for a large number of valves for control, which increases production costs. Summary of the invention

[0005] 1. Technical issues to be resolved In order to solve the above-mentioned problems in the prior art, the present invention provides an eight-way valve, which can guide the low temperature generated by the refrigerator to the battery pack in a high temperature environment, guide the low temperature generated by the refrigerator to the photovoltaic inverter, and guide the heat energy generated by the photovoltaic inverter to the battery pack at low temperatures, thereby reducing energy waste, reducing energy consumption, and eliminating the need to provide multiple valves, thereby reducing costs.

[0006] (II) Technical solution In order to achieve the above object, the main technical solutions adopted by the present invention include: An eight-way valve comprises a housing, an eight-way member and a rotating driving member, wherein the eight-way member is rotatably connected inside the housing, and the rotating driving member is drivingly connected to the eight-way member; Four flow channels are arranged inside the eight-way piece, and eight joints are arranged around the outside of the shell. The spacing between adjacent joints is the same, and both ends of a flow channel are respectively connected to a joint.

[0007] Furthermore, the rotary drive member is mounted on one side of the shell through a mounting frame.

[0008] Furthermore, a mounting opening is provided on the other side of the shell, and a cover plate is detachably connected to the mounting opening.

[0009] Furthermore, sealing grooves are arranged opposite to each other on both sides of the outer surface of the eight-way piece, sealing rings are arranged in the sealing grooves, and the eight-way piece is connected to the inner surface of the shell through the sealing rings.

[0010] Furthermore, the sealing rings are arranged on both sides of the flow channel.

[0011] Furthermore, the flow channels are respectively a first flow channel, a second flow channel, a third flow channel and a fourth flow channel.

[0012] (III) Beneficial effects The beneficial effects of the present invention are as follows: when the battery needs to be cooled during the actual use of the photovoltaic power generation system, the water can be cooled by the first refrigerator, and the water can be guided to the battery through a flow channel in the eight-way piece to cool the battery, and the cooled water can be guided back to the refrigerator through another flow channel; When the heat generating element of the photovoltaic inverter needs to be cooled, the water can be cooled by the second refrigerator, and the water can be guided to the photovoltaic inverter through a flow channel in the eight-way piece to dissipate the heat of the heat generating element, and the cooled water can be guided back to the second refrigerator through another flow channel; When it is operated at low temperature, the rotating driving part drives the eight-way part to rotate 90 degrees in the shell, and the four flow channels of the eight-way part are reconnected with the eight joints, so that the heat dissipation pipeline of the photovoltaic inverter is connected with the heating pipeline of the battery. Then the heat generated by the heating element of the photovoltaic inverter is transferred to the battery through the flow channel in the eight-way part, and the battery is heated; In this way, the low temperature generated by the refrigerator can be guided to the battery pack in a high temperature environment, the low temperature generated by the refrigerator can be guided to the photovoltaic inverter, and the heat energy generated by the photovoltaic inverter can be guided to the battery pack at low temperatures, thereby reducing energy waste, reducing energy consumption, and eliminating the need to provide multiple valves, thereby reducing costs.
