Description

Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to a turbine cooling and shock absorption system with good heat dissipation. Background Technology

[0002] Existing backpack heat dissipation systems suffer from uneven heat dissipation and low heat dissipation efficiency. For example, a backpack heat dissipation component (Chinese Patent Publication No. CN220582821U) includes a housing and a fan disposed inside the housing. The housing includes a mounting part and at least one air distribution part connected to the side of the mounting part. The fan is disposed in the mounting part, which has an air inlet. The air distribution part has several air outlets distributed along the length of the air distribution part. The fan includes a fan wheel with an air inlet cavity and several side air outlets communicating with the air inlet cavity. The air inlet communicates with the air inlet cavity, and the side air outlets communicate with the air distribution part. The air blown by the fan accumulates inside the air distribution part and cannot be dissipated immediately, resulting in uneven airflow distribution and low heat dissipation efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a turbine cooling and vibration reduction system with high cooling efficiency and uniform airflow distribution.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a turbine heat dissipation and shock absorption system, including a back panel, a heat dissipation mechanism located in the middle of the back panel, a support mechanism located on the back panel and on both sides of the heat dissipation mechanism, and a shoulder strap mechanism connected to the back panel. The heat dissipation mechanism includes a guide channel fixed on the back panel, a heat dissipation mask cooperating with the guide channel, and a heat dissipation fan. The heat dissipation mask is connected to the interlayer fabric and forms an accommodating space. The guide channel and the heat dissipation fan are located within the accommodating space. The heat dissipation fan is located at one end of the guide channel, and the air outlet of the heat dissipation fan is aligned with the guide channel. The guide channel includes a base plate and side plates located on both sides of the base plate. The distance between the base plate and the heat dissipation mask gradually decreases from the end closer to the heat dissipation fan to the other end. This utility model carrying system can be applied to backpacks. When the user uses the carrying system through the shoulder strap mechanism, the support mechanism supports both sides of the human back, while the middle heat dissipation mechanism corresponds to the human spine. The cooling fan draws in natural air and forms an airflow, which is then blown out from the air outlet. The airflow enters from one end of the guide channel and is transported to the other end. During the airflow transport process, due to the change of the bottom plate's slope, the airflow can quickly flow through the bottom plate to the heat dissipation hood and then be dispersed outwards to blow onto the human back, resulting in high heat dissipation efficiency and improved human comfort. In addition, because the depth of the far end of the guide channel is less than the depth of the near end, the air volume at the far end of the guide channel is small but the air outlet speed is fast, while the air volume at the near end is large but the air outlet speed is slow, resulting in uniform airflow throughout the guide channel.

[0005] As an improvement, a flared opening is formed between the two side plates, and the position of the cooling fan is limited by the flared opening.

[0006] As an improvement, the base plate is trapezoidal or triangular.

[0007] As an improvement, the height of the side plate gradually decreases from one end near the cooling fan to the other end, and the top of the side plate extends outward to form a connecting part, which is fixedly connected to the back panel.

[0008] As an improvement, the heat dissipation mask is made of flexible fabric, and the heat dissipation mask has an air outlet corresponding to the air guide groove area and an air inlet corresponding to the air inlet area of ​​the cooling fan.

[0009] As an improvement, the heat dissipation shroud is connected to the back panel on at least one side via a zipper.

[0010] As an improvement, the cooling fan includes a housing and a body disposed inside the housing. The top surface of the housing is provided with an air inlet, the side surface of the housing is provided with an air outlet, and a guide shroud is provided at the air outlet, the guide shroud being inclined upward.

[0011] As an improvement, the cooling fan also includes a control circuit board, which is located on the inner wall of the air guide shroud.

[0012] As an improvement, the support mechanism includes several support pads, which are fixed to the back panel by being wrapped with breathable fabric.

[0013] As an improvement, the shoulder strap mechanism includes a connecting plate and two shoulder straps arranged symmetrically on the left and right. A guide groove is formed between the bottom plate of the guide groove and the back panel. The connecting plate is T-shaped and includes a guide part inserted into the guide groove and a connecting part disposed outside the guide groove. The guide part is connected to the back panel through an elastic element. The upper end of the shoulder strap is connected to the connecting part, and the lower end of the shoulder strap is connected to the back panel through an elastic band.

[0014] The beneficial effects of this utility model compared with the prior art are:

[0015] 1. The cooling fan draws in natural air and forms an airflow, which is then blown out from the air outlet. The airflow enters from one end of the guide channel and is transported to the other end. During the airflow transport process, due to the change of the slope of the base plate, the airflow can quickly flow through the base plate to the heat dissipation mask and be blown outwards towards the back of the human body, resulting in high heat dissipation efficiency and improved human comfort.

[0016] 2. Because the depth of the far end of the guide channel is less than that of the near end, the air volume at the far end of the guide channel is small but the air velocity is fast, while the air volume at the near end is large but the air velocity is slow, resulting in uniform airflow throughout the guide channel.

[0017] 3. The side panels form a flared opening, and the position of the cooling fan is limited by the flared opening. No screws are required for fixing. With the openable heat dissipation cover, it is convenient to disassemble and maintain the cooling fan.

[0018] 4. The cooling fan blows air upwards at an angle through the airflow guide shroud, and with the airflow channel design, it can quickly expel airflow;

[0019] 5. The control circuit board for the cooling fan is installed on the inner wall of the air guide, which does not take up space and provides good heat dissipation.

[0020] 6. In the carrying strap mechanism, the elastic structure connecting the upper and lower ends of the strap can play a role in shock absorption and load reduction. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, a backpack turbine cooling and shock absorption system includes a back panel 1, a cooling mechanism located in the middle of the back panel 1, a support mechanism located on the back panel 1 and on both sides of the cooling mechanism, and a shoulder strap mechanism connected to the back panel 1.

[0030] like Figure 3 As shown, the back panel 1 is located at the back of the backpack and can be considered as part of the backpack. The back panel 1, the front panel, and the two sides form the backpack's storage space. The entire carrying system can also be a separate structure, sewn onto the back of the backpack. The back panel 1 includes a back plate as a supporting frame and an outer fabric layer covering the back plate. The heat dissipation mechanism, support mechanism, and shoulder strap mechanism are located on the outer side of the back panel 1. The inner side of the back panel 1 has a storage pocket 13, which can hold a power bank 14. The power bank 14 supplies power to the heat dissipation mechanism's electrical equipment through a wire 15 and perforations. The storage pocket 13 is operated by opening the backpack's storage space.

[0031] like Figure 2 As shown, the heat dissipation mechanism includes a flow guide 12, a heat dissipation shield 6 that mates with the flow guide 12, and a heat dissipation fan 10. The heat dissipation shield 6 is connected to the interlayer fabric and forms an accommodating space. The flow guide 12 and the heat dissipation fan 10 are located within the accommodating space. The heat dissipation shield 6 is approximately trapezoidal in shape. The left, top, and bottom edges of the heat dissipation shield 6 are all sewn tightly together. A zipper 7 is provided on the right side of the heat dissipation shield 6, through which the accommodating space is opened. Figure 5 , 6 As shown, the guide channel 12 is trapezoidal, and its shape is basically similar to that of the accommodating space. The cooling fan 10 is located at one end of the guide channel 12. Through the axial limiting fit between the guide channel 12 and the cooling fan 10, and the upper and lower constraints of the heat dissipation mask 6, the cooling fan 10 and the guide channel 12 can be reliably fixed in the accommodating space. The two ends of the guide channel 12 are connected, and it includes a base plate 121 and side plates 122 on both sides of the base plate 121. To improve the reliability of the installation of the guide channel 12, the top of the side plate 122 extends outward to form a connecting part 123. The connecting part 123 is fixedly connected to the back panel 1 by sewing. The air outlet of the cooling fan 10 is aligned with the airflow guide 12. The height of the side plate 122 gradually decreases from the end closest to the cooling fan 10 to the other end, meaning the distance between the base plate 121 and the heat dissipation shroud 6 gradually decreases from the end closest to the cooling fan 10 to the other end. Because the depth of the far end of the airflow guide 12 is less than the depth of the near end, the airflow volume at the far end of the airflow guide 12 is small but the airflow speed is fast, while the airflow volume at the near end is large but the airflow speed is slow, resulting in uniform airflow throughout the airflow guide 12. The aforementioned limiting fit is a flared opening formed between the two side plates 122 near the ends of the cooling fan 10. After installation, the position of the cooling fan 10 is limited by this flared opening, meaning the two sides of the cooling fan 10 abut against the side plates 122, preventing axial movement of the cooling fan 10. The heat dissipation shield 6 is made of a flexible material, such as leather or artificial leather. Air outlets 9 are provided on the heat dissipation shield 6 corresponding to the area of ​​the airflow guide groove 12, and air inlets 8 are provided on the heat dissipation shield 6 corresponding to the air inlet area of ​​the cooling fan 10. Natural air is drawn in through the air inlets 8, forms an airflow after passing through the cooling fan 10, and then flows out through the air outlets 9. The air inlets 8 are roughly located at the waist level, and this area has a certain gap, allowing for effective air intake. Figure 7As shown, the cooling fan 10 is a turbine fan, which includes a housing 101, a main body 100 disposed inside the housing 101, and a control circuit board 102. The housing is detachable, and the fan body can be replaced. The top surface of the housing 101 is provided with an air inlet, and the side surface of the housing is provided with an air outlet. A guide shroud 11 is provided at the air outlet. The guide shroud 11 is inclined upward, and the cooling fan 10 blows air upward through the guide shroud 11. With the design of the guide groove 12, the airflow can be quickly discharged. The control circuit board 102 is disposed on the inner wall of the guide shroud 11, which does not affect the air outlet, does not occupy space, and has good heat dissipation.

[0032] like Figure 1 As shown, the support mechanism includes several support pads 4, which are wrapped and fixed to the back panel 1 by breathable fabric. The support pads 4 on both sides are higher than the heat dissipation mechanism in the middle, forming a groove in the middle of the back panel 1, which conforms to ergonomic design and is conducive to air circulation.

[0033] like Figure 4 As shown, the shoulder strap mechanism includes a connecting plate 3 and two shoulder straps 2 arranged symmetrically on the left and right sides; the bottom plate 121 of the guide groove 12 forms a guide groove between it and the back panel 1, and the upper end of the guide groove 12 forms the inlet and outlet of the guide groove; the connecting plate 3 is T-shaped, and includes a guide part 32 inserted into the guide groove and a connecting part 31 provided outside the guide groove. The guide part 32 is connected to the back panel 1 through an elastic element 15. The elastic element can be an elastic band or a spring. The connecting part 31 is provided with two connecting holes. The upper end of the shoulder strap 2 is connected to the connecting hole of the connecting part 31, and the lower end of the shoulder strap 2 is connected to the back panel 1 through an elastic band 5; the elastic structure connecting the upper and lower ends of the shoulder strap 2 can play a role in reducing the load.
