DETAILED DESCRIPTION

[0034] Combined with Figure 1-Figure 8 The portable integrated outdoor power supply device convenient for use in a micro base station comprises a power box 12, the power box 12 is equipped with a cover 10, a handle 11 is fixedly mounted on the power box 12, and the design of the handle 11 makes the present application easy to carry; a battery slot 16 is provided in the power box 12, at least one mounting frame 24 is fixedly mounted in the battery slot 16, air holes 25 are evenly provided on the mounting frame 24 for ventilation, a battery pack is installed on the inner wall of the battery slot 16 and the mounting frame 24, and at least one power supply device input port and at least one power supply device output port are fixedly mounted at the bottom of the power box 12 to provide power protection for the operation of the micro base station; because it is used outdoors, the power supply device input port and output port of the present application are required to withstand lightning strikes of at least 20ka and 8 / 20us;

[0035] A coolant pipe 17 is provided in the battery slot 16, and the coolant pipe 17 is fixed on each of the mounting frames 24. The coolant circulates in the coolant pipe 17, and is used to directly dissipate heat in the space in the battery slot 16. The coolant pipe 17 is arranged in a curved shape on the mounting frame 24 to optimize the heat dissipation effect of the coolant pipe 17;

[0036] In order to drive the flow of coolant in the coolant pipe 17, a cooling chamber 26 is also opened in the power box 12, and a water tank 22 and a water pump 21 are fixed in the cooling chamber 26. The water tank 22 is fixedly connected to one end of the coolant pipe 17, and the water pump 21 is fixedly connected to the other end of the coolant pipe 17. The water tank 22 and the water pump 21 are fixedly connected through a pipeline. The water tank 22 is filled with coolant. After the water pump 21 is started, the coolant in the water tank 22 is extracted, and the coolant in the water tank 22 is circulated in the coolant pipe 17, so as to continuously bring out the heat in the battery slot 16 to achieve the heat dissipation effect.

[0037] Considering that the battery pack and wires that generate relatively serious heat are installed on the inner wall of the battery slot 16, a composite heat dissipation component is also provided on the cooling chamber 26, and the composite heat dissipation component includes heat sinks 18 evenly fixed on the inner wall of the cooling chamber 26. The heat sinks 18 are made of metal and can directly conduct the heat from the inner wall of the battery slot 16 to the cooling chamber 26. The coolant pipe 17 in the cooling chamber 26 is also coiled between the heat sinks 18 in a curved shape, thereby cooling the heat sinks 18 and greatly increasing the heat dissipation area.

[0038] In order to further optimize the heat dissipation effect, grooves are opened on both sides of the cooling chamber 26, and a ventilation plate 13 is fixed in the groove of the cooling chamber 26. Ventilation holes 15 are evenly opened on the ventilation plate 13. Through the ventilation holes 15, natural wind from the outside will pass through each of the heat sinks 18 and the coolant pipes 17, thereby achieving further heat dissipation of the heat sinks 18 and the coolant pipes 17.

[0039] Furthermore, in order to better dissipate the heat of the coolant in the water tank 22, fins 23 are evenly fixed on the water tank 22 to enhance the heat dissipation effect.

[0040] In the case of a sudden rise in temperature or even spontaneous combustion, the above heat dissipation means are not fast enough. To solve this problem, a sleeve 36 is provided at a part of the coolant pipe 17 in the cooling chamber 26. At least one water spray port 37 is evenly provided on the sleeve 36. Water spray holes 39 having the same number as the water spray ports 37 are provided on the coolant pipe 17 at the position of the sleeve 36. A sealing layer 38 is fixed in the sleeve 36. The sealing layer 38 is used to block each of the water spray holes 39. A push block No. 1 34 is fixed on one side of the sleeve 36. A push groove No. 1 40 is provided in the push block No. 1 34. A push rod No. 1 41 is inserted in each of the push grooves No. 1 40. The push rod No. 1 41 is cylindrical and has a cross-sectional diameter close to the width of the push groove No. 1 40. Each of the push rods No. 1 41 is fixed on the vertical rod 30. The vertical rod 30 is fixed on the lifting rod 29. The lifting rod 29 is controlled to extend and retract by the electric telescopic rod 20.

[0041] A temperature sensor 27 is fixed in the battery slot 16. The temperature sensor 27 is used to detect the temperature in the battery slot 16. A control terminal is fixedly installed in the battery slot 16. When the temperature sensor 27 detects that the temperature in the battery slot 16 is too high, it feeds back to the control terminal. The control terminal controls the electric telescopic rod 20 to control the contraction of the lifting rod 29, thereby driving the vertical rod 30 and the No. 1 push rod 41 on the vertical rod 30 to descend. The No. 1 push block 34 and the pipe sleeve 36 are driven to rotate by the descent of the No. 1 push rod 41. After the pipe sleeve 36 rotates, it drives the water spray port 37 to align with the water spray hole 39. At this time, the coolant in the coolant pipe 17 will be sprayed along the water spray hole 39 and the water spray port 37 under pressure to the inner wall of the cooling chamber 26 for cooling;

[0042] Furthermore, in order to expand the cooling range of the coolant, a water-permeable layer 19 is fixed on the inner wall of the cooling chamber 26 and the inner side of the heat sink 18. When the coolant is sprayed onto the water-permeable layer 19, it will penetrate along the water-permeable layer 19 to various positions of the inner wall of the cooling chamber 26 and each of the heat sinks 18 for comprehensive heat dissipation.

[0043] In particular, in order to accelerate the water seepage effect, the water seepage layer 19 may be made of non-woven fabrics or other high polymer materials with strong water permeability.

[0044] In addition, in order to enhance the cooling effect of the spraying of the coolant, the applicant hopes to have a better air intake effect to enhance the volatilization speed of the coolant. The specific design is:

[0045] A groove is opened on the back of the power box 12 to connect to the cooling chamber 26, and at least one connecting column 42 is fixedly installed in the groove on the back of the power box 12. An air guide plate 28 is rotatably installed on the connecting column 42, and a No. 2 push block 33 is fixedly installed on one side of the air guide plate 28. A No. 2 push groove 32 is opened in the No. 2 push block 33, and a No. 2 push rod 31 is inserted in each of the No. 2 push grooves 32. The No. 2 push rod 31 is cylindrical and has a cross-sectional diameter close to the width of the No. 2 push groove 32. Each No. 2 push rod 31 is fixedly set on the vertical rod 30. When the vertical rod 30 descends, the No. 2 push rod 31 is driven to descend, thereby driving the No. 2 push block 33 and the air guide plate 28 to rotate around the connecting column 42, thereby forming a vent, thereby increasing the ventilation area in the cooling chamber 26.

[0046] It should be particularly noted that, in order to prevent rainwater from entering, the upper and lower sides of each of the wind guide plates 28 are inclined, and the sides between two adjacent wind guide plates 28 are almost fitted together, which can effectively prevent water from entering, and the second push block 33 is fixed to the upper half of the wind guide plate 28, so that the wind guide plate 28 is also inclined outward after rotation, which can prevent rainwater from drifting in.

[0047] In addition, in order to facilitate the disassembly and assembly of the pipe sleeve 36 on the coolant pipe 17, the pipe sleeve 36 is made of elastic plastic material.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
