Description

An automatic external heat sink for notebook computer

technical field

The utility model patent relates to an automatic notebook computer external radiator, especially a suction type notebook computer external radiator containing a temperature sensor, an automatic wind speed control module and a screw fixer.

Background technique

Existing external radiators for notebook computers are divided into base radiators and external suction radiators.

The pedestal radiator achieves the purpose of cooling the laptop by placing the laptop on it and directly blowing air to the bottom of the laptop through several fans on it. This method basically does not take up space and is easy to use, but the general cooling effect is not good. good.

In another way, the external suction radiator extracts the hot air from the notebook body through the notebook computer exhaust port to achieve the purpose of cooling the notebook computer. This method adopts a more direct way to cool the notebook computer, and the effect is better than that of the chassis radiator. Obviously a lot, but most of the existing external heat sinks are generally customized for a certain type of notebook computer, and the versatility is poor. And the use of external switches and external controllers is inconvenient to use.

Contents of the invention

The utility model provides a novel notebook computer external automatic radiator. The heat sink overcomes the design shortcomings of the existing external heat sink for notebook computers, and inherits the feature of convenient design and installation. To solve the problems raised in the background technology above.

The technical solution adopted by the utility model to solve the technical problem is: place the entire radiator control unit and the suction fan in a square casing, and provide a 5V working power supply to the radiator by a USB power supply directly connected to the notebook computer , the heat sink is fixed to the heat dissipation port of the notebook computer by the screw fixer under the action of the rubber fixing head and the bottom fixing plate, and the air inlet of the heat sink is aligned with the heat dissipation port of the notebook computer. The temperature sensor at the air inlet of the radiator senses the temperature at the cooling outlet of the notebook computer, and sends the signal to the computing control module. Here we set the temperature below 30 degrees and use the lowest speed to ensure the lowest cooling efficiency. When the temperature is above 50 degrees, the fan works at a high speed. The utility model adds an automatic control module to the existing external fan. Compared with the current form of manual speed regulation, the utility model saves a lot of manual control work, is simple to operate, convenient and practical, and has low cost.

The beneficial effects of the utility model are: convenience and high efficiency, simple operation, low cost, economical and applicable.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 1 is a front view of an external radiator for a notebook computer.

Figure 2 is a diagram of the operating structure of an external radiator for a notebook computer.

detailed description

In the figure 1—radiator square shell, 2—USB power supply interface, 3—radiator air inlet, 4—screw holder, 5—rubber fixing head, 6—bottom fixing plate, 7—temperature sensor, 8—fan, 9 — Wind speed calculation control module.

In Figure 1, the 5V power supply is fed into the radiator square shell (1) through the USB power supply interface (2), and the radiator is acted by the screw holder (4) on the rubber fixing head (5) and the bottom fixing plate (6). Fix it on the cooling vent of the notebook computer, and make the radiator air inlet (3) align with the cooling vent of the notebook computer.

In Fig. 2, the temperature sensor (7) at the radiator air inlet (3) senses the temperature at the cooling outlet of the notebook computer, sends the signal to the wind speed calculation control module (9), and controls the fan to run at different temperatures Different working gears, specifically, when the temperature is below 30 degrees, the lowest speed operation state is used to ensure the lowest heat dissipation efficiency. When the temperature is 30 degrees to 50 degrees, the fan works at a medium speed. When the temperature is above 50 degrees, the fan works at a high speed. .
