Abstract
Description
Technical Field
[0001] This invention belongs to the field of power supply technology, specifically relating to a dual power supply with temperature control. Background Technology
[0002] Currently, there are three main types of heat dissipation for dual power supplies: one is natural heat dissipation through heat dissipation holes, another is rapid heat dissipation through a fan, and the third is heat dissipation through heat transfer from a sealed casing. In the first two heat dissipation methods, the heat dissipation holes or ventilation holes are exposed for a long time, and dust and other substances can easily accumulate and block the heat dissipation holes or ventilation holes, affecting the heat dissipation function. In the last heat dissipation method, the internal space is sealed for a long time, so heat can easily accumulate for a long time and cannot meet people's heat dissipation needs. Summary of the Invention
[0003] In view of the problems existing in the prior art, the present invention provides a dual power supply with temperature control to solve the above-mentioned technical problems.
[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution: A dual power supply with temperature control includes a housing and a power supply fixed inside the housing. The housing includes a base plate, a back plate at one end of the base plate, side plates on both sides of the base plate, and an L-shaped baffle. A protective cover for the power supply is also provided inside the housing, the cover being made of a perforated plate or filter screen. The L-shaped baffle includes a top plate and a front plate, the top plate being located above the protective cover, the top end of the front plate being connected to the top plate, and the bottom end contacting the base plate. A partition is provided inside the housing, the partition having a vent and a fan. An elastic telescopic member is provided between the partition and the front plate, one end of the elastic telescopic member being connected to the partition and the other end to the front plate. A temperature control device is installed inside the housing, connected to the fan: when the temperature inside the housing is greater than or equal to a threshold, the temperature control device controls the fan to operate; when the temperature inside the housing is less than the threshold, the temperature control device controls the fan to stop operating.
[0005] Preferably, there are two power sources.
[0006] Preferably, the bottom surface of the top plate is provided with bristles.
[0007] Preferably, the elastic telescopic component is an elastic rope or a spring.
[0008] Preferably, a fixing block is provided on the partition, and one end of the elastic telescopic member is connected to the fixing block; a fixing rod passes through the front plate, one end of the fixing rod located inside the housing is connected to the other end of the elastic telescopic member, and a nut is threadedly connected to the other end of the fixing rod located outside the housing.
[0009] Preferably, the two sides of the L-shaped baffle are slidably connected to the corresponding side plates.
[0010] Preferably, the protective cover is detachably connected to the base plate or back plate.
[0011] The dual power supply with temperature control provided by this invention initially dissipates heat through heat transfer from the outer casing. As heat slowly accumulates inside the casing, the heated air expands, pushing the front panel and creating gaps between the top and back panels, as well as between the front and bottom panels, allowing for slow cooling of the interior. When heat rapidly accumulates, the expanded air pushing the front panel is insufficient for rapid heat dissipation. When the temperature inside the casing exceeds a temperature control threshold, the temperature control device activates a fan to blow air towards the front panel. Combined with the pushing action of the expanding air, this causes the front panel to move significantly away from the back panel. Under the fan's influence, airflow enters the casing, passes through holes in the cover, and finally flows outward through the space between the front and bottom panels, achieving rapid heat dissipation. When the temperature inside the casing falls below the threshold, the temperature control device stops the fan, and the L-shaped baffle returns to its original position under the action of the elastic telescopic component. Therefore, this dual power supply combines dustproofing and heat dissipation functions, better meeting people's needs. Attached Figure Description

Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.
[0014] In this embodiment, the present invention provides a dual power supply with temperature control, see [link to example]. Figure 1 and Figure 2The device includes a housing and a power supply 11 fixed inside the housing. Preferably, there are two power supplies. In this embodiment, "power supply" generally refers to a power supply module or battery, etc., and is not specifically limited here. The housing includes a bottom plate 12, a back plate 13 located at one end of the bottom plate, side plates 14 located on both sides of the bottom plate, and an L-shaped baffle. The housing also has a protective cover 16 that can cover the power supply. The protective cover is made of a perforated plate or a filter screen. The L-shaped baffle includes a top plate 15-1 and a front plate 15-2. The top plate is located above the protective cover, and the top of the front plate is connected to the top plate. The bottom end contacts the base plate; a partition 17 is provided inside the outer shell, and a vent and a fan 18 are provided on the partition. An elastic telescopic member 19 is provided between the partition and the front plate, one end of the elastic telescopic member is connected to the partition, and the other end is connected to the front plate; a temperature control device 20 is installed inside the outer shell, and the temperature control device is connected to the fan: when the temperature inside the outer shell is greater than or equal to a threshold, the temperature control device controls the fan to operate; when the temperature inside the outer shell is less than the threshold, the temperature control device controls the fan to stop operating. It should be noted that the above threshold can be set to one or two. When set to two, when the temperature inside the outer shell is greater than or equal to the larger threshold, the temperature control device controls the fan to operate; when the temperature inside the outer shell is less than the smaller threshold, the temperature control device controls the fan to stop operating. This can be set by those skilled in the art according to actual needs, and no specific limitation is made here.
[0015] When the aforementioned dual power supply with temperature control is in use, heat dissipation initially relies on heat transfer from the casing. As heat slowly accumulates inside the casing, the air inside expands due to heat, pushing the front panel and creating gaps between the top and back panels, as well as between the front and bottom panels, allowing for slow cooling of the casing's interior. When heat rapidly accumulates inside the casing, the air expands due to heat, pushing the front panel, but this is insufficient to meet the demand for rapid heat dissipation. When the temperature inside the casing exceeds or equals the temperature control threshold, the temperature control device activates the fan to blow air onto the front panel. Combined with the pushing action of the expanding gas, this causes the front panel to move significantly away from the back panel. Under the action of the fan, airflow enters the casing, passes through the holes in the cover, and finally flows outward through the space between the front and bottom panels, achieving rapid heat dissipation. When the temperature inside the casing falls below the threshold, the temperature control device stops the fan, and the L-shaped baffle returns to its original position under the action of the elastic telescopic component.
[0016] In actual manufacturing, it is preferable to provide heat dissipation holes or filter holes on the top and sides of the protective cover. Brush bristles can also be provided on the bottom surface of the top plate to clean the top surface of the protective cover when the top plate moves.
[0017] The temperature control device described above can use existing temperature control devices, such as temperature controllers, or a temperature sensor can be installed inside the enclosure. The temperature sensor is connected to a controller or processor, and then the fan is connected to a microcontroller or processor to control the operation of the fan.
[0018] In this embodiment, the elastic telescopic component can be an elastic rope or a spring, and the arrangement of the elastic telescopic component can be found in [reference needed]. Figure 3 A fixing block 21 is provided on the partition, and one end of the elastic telescopic member is connected to the fixing block; a fixing rod 22 passes through the front plate, with one end of the fixing rod inside the housing connected to the other end of the elastic telescopic member, and a nut 23 threadedly connected to the other end of the fixing rod outside the housing. This structure allows adjustment of the tension of the elastic telescopic member by tightening or loosening the nut, which is beneficial for adjusting the movement sensitivity of the L-shaped baffle.
[0019] As a preferred embodiment, the two sides of the L-shaped baffle are slidably connected to the corresponding side plates. During manufacturing, the top plate can be slidably connected to the side plates, or both the top plate and the front plate can be slidably connected to the side plates at the same time. No specific limitation is made here.
[0020] In a preferred embodiment, the protective cover is detachably connected to the base plate or back plate. By setting the protective cover to be detachably connected, when replacing power supplies or other components, the L-shaped baffle can be pulled to expose the protective cover, and then the protective cover can be removed before replacing power supplies or other components.
