Description

Technical Field

[0002] The heat pump system for a new energy light truck is a complex system integrating multiple circuits. These circuits, precisely controlled by controllers and components, manage the temperature of key vehicle components. For example, a typical new energy light truck heat pump system consists of the following components: a first circuit for heating the vehicle's air conditioner; a second circuit for cooling the transmission, electronic controller, and motor components; a third circuit for heating and cooling the battery pack; and a fourth circuit for the refrigerant, which provides cooling for the vehicle's air conditioner.

[0003] For example, in the heat dissipation part of the battery pack, since the battery pack generates heat quickly and the heat is high, relying solely on the plate radiator in the circulation loop will cause the battery pack to dissipate heat slowly, which can easily affect the normal use of the battery pack.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0019] The embodiment of the present application discloses a new energy light truck heat pump system unit. Figures 1 to 5 The heat pump system for new energy light trucks includes a circulation loop and an input pipeline connected between the water pump and the four-way valve in the circulation loop. The circulation loop can be configured with the following branches: a first circulation loop for heating the vehicle's air conditioner; a second circulation loop for cooling the transmission, electronic controller, and motor components; a third circulation loop for heating and cooling the battery pack; and a fourth circulation loop for circulating refrigerant to cool the vehicle's air conditioner. The input pipeline can include a flow guide tube 10, a flow spoiler 20, a spiral tube 30, an input tube 40, an output tube 50, at least one set of brackets 60, and a mounting base 70. The spiral tube 30 is installed within the flow guide tube 10, with both ends extending outside the flow guide tube 10. Openings are formed at both ends of the spiral tube 30, allowing for the circulation of a commonly used cooling medium in the prior art. The input pipe 40 and the output pipe 50 are respectively connected and arranged at the two ends of the guide pipe 10. The input pipe 40 is connected to the output end of the water pump in the circulation loop, and the output pipe 50 is connected to the four-way valve in the circulation loop. This allows the input pipe to be installed, for example, at the input section of the heat dissipation portion of the battery pack, and allows the hotter circulating medium to be cooled by the input pipe before entering the plate radiator. The spoiler 20 is arranged on the inner side of the spiral tube 30, and the two ends of the spoiler 20 are respectively rotatably connected to the opposite ends of the guide pipe 10, so that the spoiler 20 is rotatably arranged on the inner side of the guide pipe 10. The deflection of the spoiler 20 can be used to better contact the spiral tube 30 for cooling the circulating medium flowing in the guide pipe 10. At least one set of bracket portion 60 and fixing seat 70 is used to support and fix the guide pipe 10.

[0020] In this embodiment, the flow guide tube 10 includes a tube section 11, two positioning rings 12, and two closure caps 13. The tube section 11 has openings at both ends. The two positioning rings 12 are formed on the inner walls of the tube section 11 at each end. The two closure caps 13 snap onto the openings at both ends of the tube section 11 and are fixedly connected thereto, sealing the tube section 11. The closure caps 13 contact the locating rings 12 on the side facing the locating rings 12, thereby positioning the closure caps 13.

[0021] In this embodiment, the spoiler 20 includes a rotating shaft 21 and a fan blade structure. The two ends of the rotating shaft 21 are rotatably connected to the two closing covers 13 respectively, and the fan blade structure is formed on the outer wall of the rotating shaft 21. The input pipe 40 is inserted obliquely on the guide pipe 10, and one end of the input pipe 40 located in the guide pipe 10 faces the fan blade structure of the spoiler 20, so that the circulating medium can impact the fan blade structure of the spoiler 20 after being input from the input pipe 40, causing the spoiler 20 to rotate. The fan blade structure includes a plurality of first disturbance blades 22 and a plurality of second disturbance blades 23. The plurality of first disturbance blades 22 and the plurality of second disturbance blades 23 are alternately formed on the outer wall of the rotating shaft 21, and a concave and convex alternating structure is formed between the plurality of first disturbance blades 22 and the plurality of second disturbance blades 23, thereby increasing the contact area between the fan blade structure and the circulating medium.

[0022] In this embodiment, the spiral tube 30 may be made of a heat-conducting material in a spiral shape, so that heat exchange can be performed when the spiral tube 30 contacts the circulating medium.

[0023] In this embodiment, the bracket portion 60 comprises two symmetrical hoop structures, each comprising a base section 61, a raised section 62, and a sleeve section 63. The raised section 62 is formed on the base section 61, and the sleeve section 63 is formed on top of the raised section 62. The sleeve section 63 is configured in an arc shape to match the flow guide tube 10, enabling it to support the flow guide tube 10. The base section 61 can be connected to the fixing base 70 via bolts, thereby securing the bracket portion 60 to the fixing base 70. This allows at least one set of bracket portions 60 to be mounted on the outside of the flow guide tube 10 for support.

[0024] In this embodiment, the fixing seat 70 can be made of a steel plate bent into the shape shown in the figure, and the ends of the input pipe 40 and the output pipe 50 located outside the guide pipe 10 both pass through the side wall of the fixing seat 70, and the outer walls of the input pipe 40 and the output pipe 50 are fixedly connected to the fixing seat 70, so that the fixing seat 70 is used to auxiliary support the input pipe 40 and the output pipe 50.

[0025] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
