Description

Technical Field

[0001] The invention relates to a heat dissipation device, in particular to a mobile power supply heat dissipation device. Background Art

[0002] As technology develops faster and faster, people use electronic products with various functions in their daily lives, and the power capacity required by electronic products is also increasing.

[0003] It is very inconvenient when people need to use electricity outdoors, so many people choose to carry and use mobile power supplies when outdoors. However, when many power supplies are in use, the batteries in the power supplies will generate heat, which will reduce the service life of the battery. When the battery temperature is too high, there may even be a risk of explosion. The current heat dissipation devices directly open holes in the outer shell of the power supply for heat dissipation, but the air circulation speed is slow, which is not convenient for quickly dissipating the heat generated by the battery, resulting in poor heat dissipation effect. Summary of the invention

Two large fans are fixedly connected to the top of the inner wall of the base. The two large fans are symmetrically arranged. Two ventilation plates are fixedly connected to the top of the base. There are five ventilation holes on both sides of the base. The large fans are located under the ventilation plates, and the two ventilation plates are respectively located between the fixed box body and the movable box body.

[0010] As an improvement of the above scheme, it also includes a driving mechanism, which includes a linkage rod, a driving gear, a fixed frame, a large gear, a movable block, a push rod and a limit frame. The bottoms of the two large fans are rotatably connected to the linkage rod, the bottoms of the two linkage rods are fixedly connected to the driving gear, the bottom of the inner wall of the base is fixedly connected to four fixed frames, two fixed frames form a group, and the two groups of fixed frames are symmetrically arranged.

Each large gear is fixedly connected to a movable block, the bottom of each slider is fixedly connected to a push rod, each push rod is fixedly connected to a limit frame, and the limit frame is slidably connected to the movable block.

[0011] As an improvement to the above scheme, it also includes a ventilation mechanism, which includes a transverse rack, a wide gear, a connecting rod, a longitudinal short rack, a longitudinal long rack, a thin rod, a dustproof plate and a pinion. The lower parts of the two sliders are fixedly connected with a transverse rack, the two transverse racks are symmetrically arranged, and two wide gears are rotatably connected in the base. The two wide gears are symmetrically arranged, and the transverse racks are meshed with the wide gears.

[0014] As an improvement to the above solution, a heat sink is also included, and a plurality of heat sinks are fixedly connected in the fixed box body and the two movable boxes.

[0015] The beneficial effects are:

[0016] 1. When charging, the user manually moves the two movable boxes away from each other, so that the small fan is deployed between the fixed box and the movable box, and the small fan blows air between the fixed box and the movable box. The large fan in the base blows air at the same time, and the wind is blown out from the ventilation plate. When the large fan is running, external air can enter the base through the ventilation holes, which can accelerate air circulation. The continuous circulation of air can achieve the effect of heat dissipation and cooling of the battery cell, thereby increasing the service life of the battery cell and reducing the possibility of explosion.

[0017] 2. When charging, the rotation of the large fan will drive the linkage rod to rotate, and the rotation of the linkage rod will drive the slider to move back and forth left and right. The reciprocating movement of the slider drives the movable box to move back and forth left and right. When the movable box moves left and right, it accelerates the surrounding air circulation, further improving the heat dissipation and cooling effect of the battery cell, thereby increasing the service life of the battery cell and reducing the possibility of explosion.

[0018] 3. The reciprocating movement of the slider causes the horizontal rack to move back and forth, and the reciprocating movement of the horizontal rack drives the longitudinal short rack to move back and forth, so that the dustproof plate swings back and forth. The reciprocating swing of the dustproof plate can accelerate the air circulation around the movable box, thereby improving the ventilation and heat dissipation of the battery cells in the movable box to achieve a cooling effect.

[0019] 4. The slider moves back and forth to drive the connecting bent frame to move back and forth. The connecting bent frame moves back and forth to drive the brush to move and rotate. The movement and rotation of the brush can clean the dust on the ventilation plate and reduce the dust accumulation on the ventilation plate, thereby enabling better ventilation and heat dissipation.

[0020] 5. The heat sink can conduct the heat generated by the fixed box and the movable box, and then dissipate it into the surrounding air through the heat sink. Then, through the large fan and the small fan, the air circulation around the fixed box and the movable box is accelerated, so as to further improve the heat dissipation and cooling effect of the battery cell, which is more conducive to increasing the service life of the battery cell and reducing the possibility of explosion.

DETAILED DESCRIPTION

[0037] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, and bonding in the prior art, which will not be described in detail here.

[0038] Example 1

[0039] A mobile power heat dissipation device, such as Figure 1-Figure 8 As shown, it includes a base 1, a slider 2, a fixed box 3, a movable box 4, a battery cell 5, an electric wire 6, a horizontal heat dissipation mechanism and a vertical heat dissipation mechanism. Four sliders 2 are slidably connected to the top of the base 1. Two sliders 2 form a group, and the two groups of sliders 2 are symmetrically arranged. The top of the base 1 is connected to a fixed box 3 by bolts. A handle is provided on the top of the fixed box 3. The fixed box 3 is located between the two groups of sliders 2. A movable box 4 is connected between the two sliders 2 of each group by bolts. Battery cells 5 are installed in the fixed box 3 and the two movable boxes 4.

During charging, the user manually moves the two movable boxes 4 away from each other, and the movement of the movable box 4 drives the rotating rod 74 to slide in the slide rail 73. The sliding of the rotating rod 74 drives the small fan 72 to rotate 90 degrees clockwise, so that the small fan 72 is deployed between the fixed box 3 and the movable box 4. The small fan 72 blows air between the fixed box 3 and the movable box 4, and the large fan 81 in the base 1 blows air at the same time, and the wind is blown out from the ventilation plate 82. When the large fan 81 is running, the external Air can enter the base 1 through the ventilation holes 83, which can accelerate air circulation.

After charging is completed, the two movable boxes 4 are moved towards each other and reset. The reset of the movable box 4 drives the rotating rod 74 to slide and reset in the slide rail 73. The sliding reset of the rotating rod 74 drives the small fan 72 to rotate 90 degrees counterclockwise. The rotation of the small fan 72 drives the fixed rod 71 to rotate, so that the small fan 72 is retracted between the fixed box 3 and the movable box 4.
