Description

Technical Field

[0001] This utility model relates to the technical field of shell heat dissipation equipment, and specifically to a shell ventilation and heat dissipation mechanism for a portable life support system. Background Technology

[0002] Portable life support systems are integrated, portable devices that create an independent, controllable miniature life support environment for the user. They enable vital sign monitoring and life support during patient transport, allowing for extended transport and enabling patients to receive treatment at hospitals more comfortably, thus improving survival rates within the golden window of care. However, because they integrate multiple functions, several devices may operate simultaneously for extended periods. In such cases, the overall heat dissipation of the system needs to be considered to prevent the internal temperature from failing to drop in time and causing the system to shut down.

[0003] The existing heat dissipation structure is not designed to focus on the main heat-generating components. During the air intake process, the air moves in different directions and cannot be concentrated on the main heat-generating area to remove the heat from that area. In addition, the existing heat dissipation structure also has the problem that dust carried by the air after entering the system accumulates on the surface of the equipment and dust clogs the filter screen, which affects the heat dissipation of the equipment, resulting in poor heat dissipation effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ventilation and heat dissipation mechanism for the outer shell of a portable life support system, which can solve the problems mentioned in the background art and improve the ventilation and heat dissipation effect of the outer shell.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A portable life support system's outer shell ventilation and heat dissipation mechanism includes an outer shell. A main air inlet with uniformly distributed distribution is located on the right side of the center of the bottom plate of the outer shell. Auxiliary air inlets with uniformly distributed distribution are located on the bottom plates on both sides of the main air inlet. A honeycomb-shaped air outlet is located on the left side of the rear side plate of the outer shell. A perforated plate with uniformly distributed ventilation holes is installed above the bottom plate. A cooling fan is installed on the perforated plate and positioned close to the main air inlet. A guide plate for uniform airflow and heat dissipation is installed at the center of the bottom plate, forming a flow channel between adjacent guide plates to guide airflow from the main air inlet. A first high-density dustproof net is detachably installed on the bottom of the bottom plate opposite the main air inlet, and a second high-density dustproof net is detachably installed on the bottom of the bottom plate opposite the auxiliary air inlets. Four support legs are provided at the bottom of the outer shell.

[0007] In the aforementioned portable life support system's outer shell ventilation and heat dissipation mechanism, the guide plate is bent along the main air inlet towards the air outlet, and the top of the guide plate is connected to the bottom of the through-hole plate.

[0008] The aforementioned portable life support system's outer shell ventilation and heat dissipation mechanism has a groove at the center of the bottom of the base plate, which is arranged in a left-right direction. Linear slide rails that are slidably connected to a first high-density dustproof net are respectively arranged on both sides of the groove. A limit block is provided on the right side of the first high-density dustproof net.

[0009] The aforementioned portable life support system's outer shell ventilation and heat dissipation mechanism has symmetrically arranged T-shaped slide rails installed on the bottom plates on both the front and rear sides of the groove. The T-shaped slide rails are slidably connected to the second high-density dustproof net, and a limit plate is provided on the inner side of the T-shaped slide rails.

[0010] The aforementioned portable life support system has a housing ventilation and heat dissipation mechanism, wherein a handle is hinged to the top of the housing, and a receiving groove for accommodating the handle is also provided on the top of the housing.

[0011] The aforementioned portable life support system has a ventilation and heat dissipation mechanism for its outer shell, wherein a dustproof net is provided at the air outlet.

[0012] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0013] This invention provides a ventilation and heat dissipation mechanism for the outer shell of a portable life support system. The main air inlet, perforated plate, and guide plate work together to allow air entering through the main air inlet to flow along the direction set by the guide plate, thereby concentrating and carrying away the heat emitted from the surface of the main heating component, achieving efficient heat dissipation. Simultaneously, as air flows through the perforated plate, the impact on its surface removes dust and impurities, preventing them from entering the shell and affecting the heat dissipation of the heating component. An auxiliary air inlet, entering the shell from outside the guide plate, can promptly remove heat emitted by heating components not aligned with the guide plate, enhancing the heat dissipation effect. Dust filters at the air inlet and outlet effectively prevent dust from entering the shell, solving the problem of dust accumulation on the surface of the heating component affecting heat dissipation.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A ventilation and heat dissipation mechanism for the outer shell of a portable life support system, such as Figures 1 to 5 As shown, the device includes an outer shell 11. A main air inlet 15 with evenly distributed openings is provided on the right side of the center of the bottom plate 14 at the bottom of the outer shell 11. Auxiliary air inlets 16 are provided on the bottom plate 14 on both sides in front of and behind the main air inlet 15. A honeycomb-shaped air outlet 19 is provided on the left side of the rear side plate of the outer shell 11. A perforated plate 18 with evenly distributed ventilation holes is installed on the top of the bottom plate 14. A cooling fan is installed on the perforated plate 18 and is positioned close to the main air inlet 15.

[0018] A guide plate 17 is installed at the center of the base plate 14. The top of the guide plate 17 is connected to the bottom of the through-hole plate 18. The guide plate 17 is bent along the direction of the main air inlet to the air outlet, and a guide channel is formed between adjacent guide plates 17 to guide the air entering from the main air inlet 15. At the same time, it can guide the air evenly to the heating component and discharge it from the air outlet 19.

[0019] A first high-density dustproof net 20 is detachably installed on the bottom of the base plate 14 opposite to the main air inlet 15, and a second high-density dustproof net 21 is detachably installed on the bottom of the base plate 14 opposite to the auxiliary air inlet 16. This can prevent dust from entering the inside of the housing and causing dust to accumulate on the surface of the component, affecting the heat dissipation of the component.

[0020] The bottom center of the base plate 14 has a groove 25 arranged in the left and right direction. On both sides of the groove 25, there are linear slide rails 22 that are slidably connected to the first high-density dustproof net 20. A limit block is provided on the right side of the first high-density dustproof net 20 to ensure that the first high-density dustproof net moves into place when assembled or replaced.

[0021] T-shaped slide rails 23 are symmetrically installed on the base plates 14 located on the front and rear sides of the groove 25. The T-shaped slide rails 23 are slidably connected to the second high-density dustproof net 21. A limit plate 24 is provided on the inner side of the T-shaped slide rails 23 to limit the second high-density dustproof net 21.

[0022] Dust filters are installed at 19 air outlets to prevent external dust from entering the casing.

[0023] The bottom of the outer casing 11 is provided with four support legs 13. The support legs 13 make a certain gap between the bottom of the outer casing 11 and the ground so that the cooling fan can smoothly draw in air when it is working.

[0024] A handle 12 is hinged to the top of the outer casing 11, and a receiving groove for accommodating the handle 12 is also provided on the top of the outer casing 11, so that the handle can be stored when not in use.

[0025] The working principle of this utility model is as follows: When air is intake, the cooling fan works, and the air entering along the main air intake flows between the guide plates. At the same time, the perforated plate will cause a certain impact on the air, thereby intercepting dust in the air and reducing the entry of dust. Then, the air enters the housing through the perforated plate, carrying away the heat on the surface of the main heat-generating components and being discharged from the air outlet.

[0026] Because the air in the main air inlet moves under the limitation of the guide plate, the heat on the surface of the component opposite to the outer area of ​​the guide plate cannot be carried away in time. Therefore, by setting the auxiliary air inlet, the air can enter the cavity between the bottom plate and the through plate from both sides, and then enter the inside of the shell through the vent on the through plate, carrying away the heat of the heat-generating component located above the outer area of ​​the heat-conducting plate. The setting of the main air inlet and the auxiliary air inlet ensures that the heat inside the shell can be effectively carried out.

[0027] This invention provides a ventilation and heat dissipation mechanism for the outer shell of a portable life support system. The main air inlet, perforated plate, and guide plate work together to allow air entering through the main air inlet to flow along the direction set by the guide plate, thereby concentrating and carrying away the heat emitted from the surface of the main heating component, achieving efficient heat dissipation. Simultaneously, as air flows through the perforated plate, the impact on its surface removes dust and impurities, preventing them from entering the shell and affecting the heat dissipation of the heating component. An auxiliary air inlet, entering the shell from outside the guide plate, can promptly remove heat emitted by heating components not aligned with the guide plate, enhancing the heat dissipation effect. Dust filters at the air inlet and outlet effectively prevent dust from entering the shell, solving the problem of dust accumulation on the surface of the heating component affecting heat dissipation.
