Description

Technical Field

[0001] This utility model belongs to the field of walkie-talkie heat dissipation, and specifically relates to a walkie-talkie with good heat dissipation. Background Art

[0002] Vehicle-mounted walkie-talkies are communication tools installed inside vehicles, boasting advantages such as high transmission power and long communication distance. However, due to their high transmission power and high power consumption, these devices can overheat over 100 degrees Celsius during prolonged transmission. At such high temperatures, the performance of components deteriorates, and some components may trigger internal protection mechanisms, ceasing operation and leading to equipment malfunctions. To ensure normal operation, it is essential to dissipate the generated heat as quickly as possible.

[0003] Existing walkie-talkies typically use external heat sinks in conjunction with fans, resulting in limited heat dissipation efficiency, similar appearance, and a single design. Summary of the Invention

[0004] This invention proposes a walkie-talkie with good heat dissipation, which can effectively improve heat dissipation efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A walkie-talkie with good heat dissipation includes a back shell, a power transistor, a fan, and a rear cover. The back shell has a cavity, the fan is located on the outer front end of the back shell, the power transistor is located in the cavity and close to the fan, the outer bottom of the back shell has a heat dissipation area and a first groove, the front end of the back shell has a first vent corresponding to the power transistor and a second vent communicating with the heat dissipation area, the front end of the heat dissipation area is close to the fan, the width of the heat dissipation area gradually increases from the front end to the rear end, the first groove is spaced apart from the rear end of the heat dissipation area and penetrates the heat dissipation area along the width direction of the heat dissipation area, the front section of the heat dissipation area has multiple protrusions spaced apart, the rear section has multiple strip ribs spaced apart, each strip rib is distributed in a fan shape, the rear cover covers the heat dissipation area, and the side plate of the back shell has heat dissipation holes. On the one hand, the power transistors are positioned near the fan, allowing most of the airflow from the fan to act on the power transistors and carry away the heat generated by them. The air carrying the heat then leaves the aluminum shell through the heat dissipation holes on the back panel. On the other hand, the arrangement of protruding blocks in the heat dissipation area increases the contact area between the back shell and the air, while multiple strip ribs form multiple air ducts to control the airflow direction. This efficiently carries the hot air to the rear of the back shell and leaves the aluminum shell through the first groove. The rear cover plate covers the heat dissipation area, preventing disturbance from external airflow. In summary, this effectively improves heat dissipation efficiency.

[0007] Furthermore, the heat dissipation area is a second groove formed on the outer side of the bottom of the back cover, and the shape of the rear cover plate matches the second groove, which has a reasonable structure and an aesthetically pleasing appearance.

[0008] Furthermore, a mounting block is provided at the front end of the cavity, and a mounting groove is provided through the mounting block along the front and rear end direction of the cavity. The power tube is installed in the mounting groove, and the first vent is connected to the mounting groove. The structure is reasonable, which facilitates the installation of the power tube and improves the heat dissipation efficiency.

[0009] Furthermore, both the back shell and the mounting block are made of aluminum, which further improves heat dissipation efficiency.

[0010] Furthermore, the heat dissipation area occupies 1 / 3 to 1 / 2 of the back shell area, thereby improving heat dissipation efficiency while ensuring the strength of the back shell.

[0011] Furthermore, the protrusion can be a cylinder or a cube.

[0012] Furthermore, the rear cover is bolted to the back shell to cover the heat dissipation area.

[0013] Furthermore, it also includes a front cover plate set on the back shell to seal the cavity. Attached Figure Description
