Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, and particularly relates to a heat conduction structure for a waterproof toolbox. Background Art

[0002] When charging in the state where the toolbox cover is closed, heat accumulates inside the box during the charging process. If not dissipated in time, it will damage the items inside. There may be the following damage risks: 1. Overheating of electrical appliances: The heat generated by electrical appliances during charging cannot be effectively dissipated, which will cause the temperature of the electrical appliances to continue to rise. In the case of continuous overheating, it may affect the performance of the electrical appliances, and even cause damage to the electrical appliances or shorten their service life. 2. Battery damage: For electrical appliances using batteries, overheating may damage the batteries, resulting in a decline in battery performance, and even problems such as expansion and leakage. This not only affects the normal use of the electrical appliances, but also may pose a threat to personal safety. 3. Reduced efficiency: When electrical appliances work in an overheated environment, it may cause a reduction in their working efficiency, a slower charging speed, or an inability to work properly.

[0028] The following further describes the present utility model in detail with reference to the accompanying drawings, so that those skilled in the art can implement it according to the description in the specification.

[0029] It should be understood that the terms such as "having", "including", and "comprising" used herein do not exclude the presence or addition of one or other elements or their combinations.

[0030] As Figures 1-7 shown, a heat conduction structure 1 for a waterproof toolbox according to the present utility model includes:

[0031] The upper end of the box body 110 is provided with a box opening, and a box cover 120 is provided at the box opening.

[0032] The heat dissipation opening 121 is provided through the middle and rear part of the box cover 120.

[0033] The outer heat dissipation plate 130 is arranged on the outer side of the box cover 120. A protrusion 131 adapted to the heat dissipation opening 121 is provided at the center of the lower end surface of the outer heat dissipation plate 130, and the protrusion 131 is used to extend into the heat dissipation opening 121.

[0034] The inner heat dissipation plate 140 is arranged on the inner side of the box cover 120 and abuts against the protrusion 131;

[0035] The first waterproof ring groove 132 is arranged on the lower end surface of the outer heat dissipation plate 130 and is located on the outer periphery of the protrusion 131;

[0036] The first waterproof ring 150 is embedded in the first waterproof ring groove to provide waterproof performance.

[0037] During use, the inner heat dissipation plate 140 conducts the heat of the box body 110 to the outer heat dissipation plate 130, and the outer heat dissipation plate 130 dissipates the heat to the outside of the box body 110. During this process, the first waterproof ring 150 improves the waterproof performance at the heat dissipation opening 121.

[0038] In another embodiment, it further includes:

[0039] A pair of second waterproof ring grooves 133 are respectively arranged on the lower end surface of the outer heat dissipation plate 130 in a mirror image manner and are located on both sides of the protrusion 131;

[0040] A pair of second waterproof rings 160 are respectively embedded in the second waterproof ring grooves for further providing waterproof performance.

[0041] In another embodiment, the inner heat dissipation plate 140 and the outer heat dissipation plate 130 are respectively detachably connected to the box cover 120 through a plurality of screws 170.

[0042] In another embodiment, the inner heat dissipation plate 140 and the outer heat dissipation plate 130 are made of heat-conducting materials.

[0043] In another embodiment, a grid structure 141 is provided in the inner heat dissipation plate 140.

[0044] In another embodiment, it further includes: an EVA heat insulation sheet 180 is disposed below the inner heat dissipation plate 140. The outer periphery of the EVA heat insulation sheet 180 is adapted to the inner periphery of the box cover 120. A heat exchange area 181 is provided at a position corresponding to the inner heat dissipation plate on the EVA heat insulation sheet 180. The size of the heat exchange area 181 is adapted to that of the inner heat dissipation plate 140. A plurality of through holes 182 are evenly distributed on the heat exchange area 181. When it is summer and strong heat dissipation performance is required, the heat exchange area 181 is aligned with the inner heat dissipation plate 140, enabling rapid heat dissipation, such as Figure 6 ; when it is winter, the EVA heat insulation sheet 180 is rotated 180 degrees to make the heat exchange area 181 partially overlap with the inner heat dissipation plate 140, thereby preventing the internal temperature of the box body 110 from being too low due to excessive heat dissipation, such as Figure 7 .

[0045] In summary, for a heat-conducting structure 1 of a waterproof toolbox according to the present invention, an outer heat dissipation plate 130 and an inner heat dissipation plate 140 are respectively provided above and below the heat dissipation opening 121 of the box cover 120. A first waterproof ring groove 132 is provided on the outer heat dissipation plate, and a first waterproof ring 150 is provided in the first waterproof ring groove 132, ensuring the waterproof performance of the box body 110 while guaranteeing heat dissipation.

[0046] Although the embodiments of the present invention have been disclosed as above, it is not limited to only the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details and the illustrated examples here.
