Description

Technical Field

[0001] The utility model belongs to the field of electrical equipment, and particularly relates to a heat dissipation structure of equipment. Background Art

[0002] When electrical equipment is working, it is easy to generate a lot of heat energy, causing the temperature to rise; however, too high a temperature will affect the normal operation of the electrical equipment and even the service life of the electrical equipment, so the heat dissipation structure of the electrical equipment is crucial.

[0003] For example, a floodlight that is easy to dissipate heat (application number CN201821721792.1) disclosed in a prior patent relates to the field of lighting devices, including a lamp frame, a heat conducting plate is sealed and fixed in the lamp frame, a transparent lens is fixed at the opening of the lamp frame, a plurality of lamp beads are fixed on the side of the heat conducting plate close to the transparent lens, a plurality of heat dissipation fins are fixed in parallel on the side of the heat conducting plate away from the transparent lens, a battery box is fixed on the lamp frame, the battery box is in contact with the side of the heat dissipation fin away from the heat conducting plate, and a battery for powering the lamp beads is installed in the battery box. In the floodlight, external air enters the battery box driven by a fan, and is discharged from the battery box through the heat dissipation fins to dissipate heat for the heat conducting plate; however, although the air flow guided by the fan passes through the battery box, it does not directly correspond to the battery, resulting in a relatively insufficient heat dissipation effect on the battery; and because the floodlight is composed of a multi-layer structure such as a lamp frame and a battery box, its overall thickness is thicker.

[0005] In order to solve the above problems, the purpose of the utility model is to provide a multi-channel heat dissipation device, which is lighter and thinner.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] A multi-channel heat dissipation device, the device includes a shell, a main board, a battery, and a heat dissipation fan, the shell is provided with a receiving cavity, the main board, the battery, and the heat dissipation fan are all arranged in the receiving cavity, and the battery and the heat dissipation fan are all electrically connected to the main board; the device also includes a bracket, one side of the bracket is connected to the main board, a heat dissipation cavity is formed between the bracket and the main board, a battery mounting position and a fan mounting position are arranged at the other side of the bracket, the heat dissipation fan and the battery are arranged at the fan mounting position and the battery mounting position respectively, and an air inlet corresponding to the heat dissipation fan is arranged on the shell.

[0008] In the device, the external air is introduced from the air inlet to the air outlet under the action of the cooling fan. A part of the air passes through the first cooling air duct to dissipate the heat for the mainboard and then is discharged from the first cooling outlet. The other part passes through the second cooling air duct to dissipate the heat for the mainboard and the battery and then is discharged from the second cooling outlet. The structural arrangement of the first cooling air duct and the second cooling air duct inside the device allows the mainboard and the battery to be cooled at the same time when the device is in use, thus avoiding excessive temperatures of the battery and the mainboard, making the device more stable when in use.

[0010] Furthermore, the battery heat dissipation slot passes through the bracket, and the battery and the mainboard are respectively located on both sides of the battery heat dissipation slot. When air passes through the battery heat dissipation slot, it can also dissipate heat for the battery and the mainboard at the same time.

[0011] Furthermore, the number of the battery heat dissipation slots is more than two. This arrangement makes the heat dissipation effect of the mainboard and the battery better.

[0012] Furthermore, the battery mounting position is a groove, and the battery mounting position is connected to the battery heat dissipation slot.

[0013] Furthermore, the housing is also provided with a third heat dissipation port connected to the battery installation position. When air passes through the battery heat dissipation slot, part of the air will directly enter the battery installation position and be discharged from the third heat dissipation port, so that the heat dissipation effect of the battery is better.

[0014] Furthermore, the third heat dissipation openings are arranged on both sides of the housing, and the two third heat dissipation openings are respectively connected to the two sides of the battery installation position. This arrangement further improves the heat dissipation effect on the battery.

[0017] Furthermore, a light-transmitting member is provided at the avoidance opening, and the light-transmitting member is provided to protect the lamp beads while ensuring the lighting effect of the lamp beads.

[0018] The beneficial effect of the utility model is that in the device, the external air is introduced from the air inlet to the air outlet under the action of the cooling fan, a part of it passes through the first cooling air duct to dissipate the heat for the mainboard and then is discharged from the first cooling outlet, and the other part passes through the second cooling air duct to dissipate the heat for the mainboard and the battery and then is discharged from the second cooling outlet; through the structural arrangement of the first cooling air duct and the second cooling air duct inside the device, the device can dissipate the heat for the mainboard and the battery at the same time when in use, avoiding the battery and the mainboard from being overheated, making the device more stable when in use. In addition, the battery, cooling fan and mainboard are all integrated in the housing, and the cooling fan and the battery do not need to be installed externally, making the device thinner and lighter.
