Description

AREA OF INVENTION

[0001] The present application relates to the field of backpack technology, in particular to a turbine cooling and load relief system for backpacks. BACKGROUND OF THE INVENTION

[0002] Existing backpack carrying systems suffer from problems with uneven heat dissipation and low efficiency. For example, Chinese patent publication No. CN220582821U discloses a backpack heat dissipation assembly comprising a housing and a fan located within the housing. The housing includes a mounting part and at least one air distribution part attached to the side of the mounting part. The fan is located in the mounting part, which has an air inlet, and the air distribution part has a plurality of air outlets distributed along its length. The fan includes an impeller with an air inlet chamber and a plurality of lateral air outlet channels that communicate with the air inlet chamber. The air inlet communicates with the air inlet chamber, and the lateral air outlet channels communicate with the air distribution part.The air blown by the fan collects in the air distribution section and cannot be immediately discharged to the outside, resulting in uneven airflow distribution and low heat dissipation efficiency. SUMMARY OF THE INVENTION

[0003] The technical problem to be solved by this invention is to provide a turbine cooling and load relief system that has high heat dissipation efficiency and uniform airflow distribution.

[0004] To solve the aforementioned technical problem, the technical solution of this invention is as follows: A turbine cooling and load-relieving system comprising a back panel, a heat dissipation mechanism located in the center of the back panel, a support mechanism located on the back panel on both sides of the heat dissipation mechanism, and a belt mechanism connected to the back panel. The heat dissipation mechanism comprises an air duct attached to the back panel, a heat dissipation mask interacting with the air duct, and a cooling fan. The heat dissipation mask is connected to a partition fabric to form an enclosure. The air duct and the cooling fan are arranged within the enclosure. The cooling fan is located at one end of the air duct, and its air outlet is aligned with the air duct.The air duct comprises a base plate and side plates located on either side of the base plate. The distance between the base plate and the heat dissipation mask gradually decreases from the end near the cooling fan to the other end. This turbine cooling and load-relieving system can be applied to a backpack. When a user utilizes the turbine cooling and load-relieving system via the strap mechanism, the support mechanism rests on both sides of the user's back, while the central heat dissipation mechanism follows the user's spine. The cooling fan draws in ambient air, creates an airflow, and expels it from the air outlet. The airflow enters the air duct at one end and is transported to the other.During this process, the changing inclination of the base plate allows the airflow to quickly pass through it towards the heat dissipation mask and be exhausted outwards towards the user's back, resulting in high heat dissipation efficiency and improved user comfort. Additionally, because the depth at the far end of the air duct is less than at the near end, the air volume at the far end is smaller, but the exhaust velocity is higher, while at the near end the air volume is larger, but the exhaust velocity is slower, resulting in a consistent airflow throughout the entire air duct.

[0005] In some embodiments, a bulge forms between the two side plates, and the position of the cooling fan is restricted by the bulge.

[0006] In some embodiments, the base plate is trapezoidal or triangular.

[0007] In some embodiments, the height of the side plates gradually decreases from the end near the cooling fan to the other end, and the top of the side plates extends outwards to form a connecting part that is firmly attached to the rear panel.

[0008] In some embodiments, the heat dissipation mask is made of a flexible fabric with air outlets provided in the area corresponding to the air duct and air inlets provided in the area corresponding to the air inlet of the cooling fan.

[0009] In some embodiments, at least one side of the heat dissipation mask is connected to the back panel via a zipper.

[0010] In some embodiments, the cooling fan comprises a housing and a body located within the housing. The top of the housing is provided with an air inlet, and the side with an air outlet. An upward-sloping air guide is provided at the air outlet.

[0011] In some embodiments, the cooling fan also includes a control board located on the inner wall of the air guide cover.

[0012] In some embodiments, the support mechanism comprises several soft support pads wrapped in a breathable fabric and attached to the back panel.

[0013] In some embodiments, the belt mechanism comprises a connecting plate and two symmetrically arranged belts. A guide groove is formed between the base plate of the air duct and the rear wall. The connecting plate is T-shaped and includes a guide element inserted into the guide groove and a connecting element located outside the guide groove. The guide element is connected to the rear wall via an elastic element. The upper ends of the belts are connected to the connecting element, and the lower ends of the belts are connected to the rear panel by elastic bands.

[0014] The advantageous effects of this invention compared to the prior art are as follows: 1. The cooling fan draws in ambient air and creates an airflow that is expelled from the air outlet. The airflow enters the air duct at one end and is transported to the other. During this process, the changing incline of the base plate allows the airflow to quickly pass through the base plate towards the heat dissipation mask and be exhausted outwards towards the user's back, resulting in high heat dissipation efficiency and improved user comfort. 2. Since the depth of the far end of the air duct is less than the depth of the near end, the air volume at the far end is smaller, but the outlet velocity is faster, while the air volume at the near end is larger, but the outlet velocity is slower, resulting in a uniform overall airflow in the air duct. 3. A raised section forms between the side plates, which limits the position of the cooling fan without the need for screws. Combined with the removable heat dissipation mask, this facilitates disassembly and maintenance of the cooling fan. 4. The cooling fan blows air diagonally upwards through the air guide cover, which, in conjunction with the design of the air guide duct, enables a rapid discharge of the airflow. 5. The control board for the cooling fan is mounted on the inner wall of the air guide cover, saving space, and its location provides improved heat dissipation. 6. In the strap mechanism, the elastic structures that connect the upper and lower ends of the straps can help to relieve the load.

[0015] The present invention is described in more detail below in conjunction with the accompanying figures.

[0016] As in Fig. As shown in Figure 1, a backpack turbine cooling and load relief system comprises a back panel 1, a heat dissipation mechanism located in the center of the back panel 1, a support mechanism on both sides of the heat dissipation mechanism on the back panel 1, and a strap mechanism connected to the back panel 1.

[0017] As in Fig. As shown in Figure 3, the back panel 1 is located on the back of the backpack and can be an integral part of the backpack; the back panel 1, front panel, and side panels enclose the backpack's storage compartment. The entire turbine cooling and load-dissipation system can also be sewn onto the back of a backpack as a standalone structure. The back panel 1 comprises a back plate, which serves as a support frame, and an outer fabric layer wrapped around the back plate. The heat dissipation mechanism, support mechanism, and strap mechanism are located on the outside of the back panel 1. The inside of the back panel 1 is provided with a storage pocket 13, which can house a power bank 14. The power bank 14 supplies power to the electrical equipment of the heat dissipation mechanism via a wire 15 and a through-hole. The storage pocket 13 is accessible by opening the backpack's storage compartment.

[0018] As in Fig. As shown in Figure 2, the heat dissipation mechanism comprises an air duct 12, a heat dissipation mask 6 that interacts with the air duct 12, and a cooling fan 10. The heat dissipation mask 6 is connected to a partition fabric to form an enclosure in which the air duct 12 and the cooling fan 10 are located. The heat dissipation mask 6 is generally trapezoidal. The left, upper, and lower sides of the heat dissipation mask 6 are sewn together, while the right side is provided with a zipper 7 that allows the enclosure to be opened. As shown in Figure 2, the heat dissipation mask 6 is connected to a partition fabric to form an enclosure. Fig. 5 and Fig. As shown in Figure 6, the air duct 12 is trapezoidal, its shape resembling that of the housing. The cooling fan 10 is located at one end of the air duct 12. The axial restraint between the air duct 12 and the cooling fan 10, as well as the vertical restraint provided by the heat dissipation mask 6, reliably secures the cooling fan 10 and the air duct 12 within the housing. Both ends of the air duct 12 are open. It comprises a base plate 121 and side plates 122 on either side of the base plate 121. To improve the installation reliability of the air duct 12, the upper surface of the side plates 122 extends outwards to form a connecting element 123, which is attached to the rear panel 1 by sewing. The air outlet of the cooling fan 10 is aligned with the air duct 12.The height of the side plates 122 gradually decreases from the end near the cooling fan 10 to the far end, meaning that the distance between the base plate 121 and the heat dissipation mask 6 also gradually decreases from the far end near the cooling fan 10 to the far end. Since the depth of the far end of the air duct 12 is less than the depth of the near end, the air volume at the far end is smaller, but the outlet velocity is faster, while the air volume at the near end is larger, but the outlet velocity is slower, resulting in a uniform overall airflow in the air duct 12. The aforementioned restriction is a bulge that forms between the ends of the two side plates 122 near the cooling fan 10.After installation, the position of the cooling fan 10 is restricted by the raised section, meaning that the sides of the cooling fan 10 abut the side plates 122, thus preventing axial movement of the cooling fan 10. The heat dissipation mask 6 is made of a flexible material, such as leather or imitation leather, and is provided with air outlets 9 in the area corresponding to the air duct 12 and with air inlets 8 in the area corresponding to the air intake of the cooling fan 10. Natural air is drawn in through the air inlets 8, shaped into an airflow by the cooling fan 10, and then expelled through the air outlets 9. The air inlets 8 are located approximately at the user's waist, where a specific gap is present to allow efficient air intake. As shown in... Fig. As shown in Figure 7, the cooling fan 10 is a turbine fan comprising a housing 101, a body 100 located within the housing 101, and a control board 102. The housing is removable, allowing the fan body to be replaced. The upper surface of the housing 101 has an air inlet, and the side has an air outlet with an air guide cover 11. The air guide cover 11 is inclined upwards. The cooling fan 10 blows air obliquely upwards through the air guide cover 11, which, in conjunction with the design of the air duct 12, enables rapid expulsion of the airflow. The control board 102 is located on the inner wall of the air guide cover 11, so that it does not obstruct the airflow, does not take up space, and is situated in a location with increased heat dissipation.

[0019] As in Fig. As shown in Figure 1, the support mechanism comprises several soft support pads 4 wrapped in a breathable fabric and attached to the back panel 1. The lateral support pads 4 are higher than the central heat dissipation mechanism, forming a groove in the center of the back panel 1 that conforms to the ergonomic design and facilitates air circulation.

[0020] As in Fig.As shown in Figure 4, the belt mechanism comprises a connecting plate 3 and two symmetrically arranged belts 2. A guide groove is formed between the base plate 121 of the air duct 12 and the back panel 1. The upper end of the air duct 12 forms the inlet and outlet of the guide groove. The connecting plate 3 is T-shaped and includes a guide element 32 inserted into the guide groove and a connecting element 31 located outside the guide groove. The guide element 32 is connected to the back panel 1 by an elastic element 16, which can be an elastic band or a spring. The connecting element 31 is provided with two connection holes. The upper ends of the belts 2 are connected to the connection holes of the connecting element 31, and the lower ends of the belts 2 are connected to the back panel 1 by elastic bands 5. The elastic structures connecting the upper and lower ends of the belts 2 serve to reduce stress. QUOTES INCLUDED IN THE DESCRIPTION
