Background technique

At present, there are many notebook computer cooling racks on the market, the purpose of which is to improve the heat dissipation of the computer. Basically, one or more small fans are placed under the notebook computer to extract air, and the heat dissipation effect is improved by enhancing the air circulation, which is very important for heat dissipation. There is some improvement, but the heat dissipation effect is limited, the noise is loud, and it depends on the surrounding environment that is good for ventilation, otherwise the heat dissipation effect will be greatly reduced. At the same time, due to the increase of the air flow inside the notebook computer, it will cause serious dust accumulation in the notebook computer, and it has to be cleaned frequently.

The principle of liquid cooling equipment for home computers is different from that of computer cooling racks.

The cooling effect of this cooling method is very good. , has almost no dependence on the external environment, and will not cause dust accumulation inside the computer. However, it is usually only suitable for desktop computers and not for notebook computers, and certain modifications must be made to the computer, and the general price is relatively expensive.

Detailed ways

Below in conjunction with accompanying drawing, the technical scheme of the utility model is described in further detail:

The utility model discloses a novel liquid-cooled notebook computer radiator, which comprises a bracket, a liquid-cooled circulation device and a ventilation device;

The bracket is used to fix the liquid cooling sequential device and the ventilation device, including a first support plate, a second support plate, a support panel and a central partition;

The bracket panel is used to place a notebook, and the first support plate and the second support plate are used to support the bracket panel;

The central partition is arranged between the first support plate and the second support plate, and divides the space surrounded by the first support plate, the second support plate, and the support panel into a first chamber and a second chamber;

Ventilation holes leading to the first chamber and the second chamber are respectively provided on the support panel;

The liquid cooling circulation device includes a micro water pump, a cooling pipeline, a cooling liquid, a cooling box, a power module and a control module;

The control module is electrically connected to the micro-water pump, the power module, and the ventilation device respectively, and is used to control the operation of the ventilation device and the micro-water pump;

The cooling pipeline is arranged on the bracket panel, one end is connected to one end of the micro water pump through a pipeline, and the other end is connected to one end of the cooling box through a pipeline;

The other end of the micro water pump is connected with the other end of the cooling box by a pipeline;

The ventilation device is arranged in the first chamber or the second chamber.

The bracket provides support and installation space for the liquid-cooled sequential device and the micro fan, and is also the main shell of the cooling rack. When in use, the laptop needs to be placed on the bracket. The bracket increases the space between the laptop and the desktop, providing heat protection Dispersion creates a better environment and also provides space for other equipment to be installed.

At the same time, considering the distribution characteristics of the main heat source of most notebook computers, the central partition set between the bracket and the desktop adopts a rib structure, which not only strengthens the structural strength of the bracket, but also divides the space raised by the cooling rack into two spaces. , so as to force the airflow made by the micro fan to change the flow direction, so that the external airflow circulates from the cold end to the hot end of the notebook computer, or from the hot end to the cold end, and at the same time keeps the air outlet away from the user, so that the user will not be affected by the airflow of winding.

The surface of the bracket in contact with the user's computer is designed with a water pipe passage of a liquid cooling circulation device, from which the liquid flows to take away heat.

The space between the bracket and the desktop is equipped with a micro fan, which is used to create airflow and assist the heat dissipation effect of the liquid cooling, so that the air can circulate and the heat will not accumulate.

See Figure 1 and Figure 2 for a schematic view of the scaffold structure and a schematic view of the chamber.

The liquid cooling circulation device is composed of a micro water pump, a cooling pipeline, a cooling liquid and a cooling box. A part of the cooling pipeline must be arranged on the surface where the bracket is in contact with the user's computer to take away the heat. The micro water pump and the cooling box can be placed outside the bracket or hidden inside the bracket.

The micro water pump is used to provide power for the circulating flow of the coolant, powered by the power supply, and controlled by the control circuit. The micro water pump cannot use the type of water pump that must be pre-filled with water, such as a micro centrifugal pump, otherwise the user must pre-soak the water pump in order to use it. It is recommended to use a pump that can run dry, such as a peristaltic pump.

The power of the water pump does not need to be too large, as long as it can maintain the slow flow of the liquid, it is necessary to give the liquid a certain heat exchange time.

The size of the water pump should be small and not take up too much volume. The water pump can be designed to be hidden inside the bracket to protect the circuit connection while avoiding affecting the appearance.

The cooling pipeline arranged on the contact surface of the bracket and the user's notebook is used to take away the heat of the notebook through contact heat transfer, so the material of the pipeline must have a high thermal conductivity, and thin tubes made of metal materials can be used road. According to the heat source distribution of the user's computer, different pipeline distribution methods can be used on the surface, for example, the pipelines can be denser near the battery of the computer.

The cooling liquid flows in the pipes, and takes away the heat of the computer through the contact heat transfer with the computer, which has the effect of cooling.

Household laptops are generally used in relatively good conditions, and the coolant does not need to consider antifreeze and anti-boiling issues, as long as it has an appropriate heat capacity, is not corrosive, toxic, does not block the pipeline due to precipitation or chemical reactions, and is easy to replace. .

From the point of view of convenience, pure water is a good choice.

A large amount of coolant is stored in the cooling tank, which is connected to the water pump through the cooling pipeline. The cooling liquid flows out from the cooling tank, absorbs the heat of the computer, and flows back here, transferring the heat to the large amount of cooling liquid in the water tank, and the cooling liquid that brings the heat cools down, so the water tank is equivalent to a heat buffer device.

The water tank can be designed as a sealed type, or it can be designed as an open type under the condition that the coolant will not leak. The volume of the water tank should not be too large, so as not to affect the appearance and use, it can be considered to be hidden in the bracket far away from the heat source.

Due to the continuous accumulation of heat in the water tank, the heat dissipation performance of the water tank must be considered, otherwise the water cooling system will not be able to play the role of heat dissipation and cooling due to the high temperature of the coolant after a period of time. Therefore, it can be considered to design the water tank as a shape that is conducive to heat dissipation, such as having a large heat dissipation surface area, or using a metal material that is conducive to heat dissipation. It can also be designed as a detachable water tank. If the temperature of the coolant in the water tank is too high, you only need to replace the coolant.

One or more miniature fans are fixed on the bracket to create flowing airflow. With the cavity structure of the bracket, the airflow can circulate from the cold end to the hot end, or from the hot end to the cold end. A specific The way to achieve it is shown in Figure 2.

It should be noted that the micro fan is only used to assist heat dissipation, improve the air circulation environment, and avoid heat accumulation, rather than the main means of heat dissipation. The airflow is very weak, so as to avoid dust accumulation inside the computer caused by too much air flow.

The fan and the water pump can share one power supply, or use different power supplies. The power supply can use batteries, USB power supply or universal AC to low voltage DC power adapter. The operating voltage of the fan and water pump should be about 5V, and the current should be about 2A to ensure safety and low power consumption.

The fan and water pump are controlled by the control circuit. The control circuit controls the on/off and speed of the fan, and controls the on/off and power of the water pump.

Fig. 3 is a schematic diagram of liquid cooling pipeline connection and circuit connection.

After the circuit system is connected with the fan and the water pump, it is fixed on the bracket. For the sake of aesthetics and safety, most of the circuit system is hidden inside the bracket space, leaving only the power connector and control panel for users to operate.

Specific parameters in a specific implementation example are given below.

Micro fan parameters: DC 5V 0.2A 10cm micro fan, powered by USB.

Micro water pump parameters: DC 3V 5W micro peristaltic pump, powered by two 1.5V AAA batteries.

Bracket panel: 4mm plexiglass plate, cut into shape using a laser engraving machine.

Cooling pipeline: Use a latex tube with a diameter of 3*4mm as the cooling pipeline to connect the water tank and the water pump. The cooling pipelines on the use panel are equidistant and densely distributed, as shown in Figure 3 for details.

Cooler Tank: Use a drink bottle as a simple water tank.

Coolant: Use purified water.

Circuit system: several wires, one battery box and one switch, soldered with electric soldering iron.

The thermal drying gun of the soldering station is used as a local heat source to heat the heat dissipation surface of the cooling frame of the present invention, and the outlet temperature of the thermal drying gun is about 80°C. When the liquid cooling system was not connected, the local temperature rose rapidly from 30°C to 60°C, so that the experiment was terminated. When the liquid cooling system is switched on, the local temperature rises from 30°C to 37°C and remains stable. It can be seen that the cooling effect of the cooling rack is very good.

Similarly, we also tested the actual use of the cooling rack with a laptop. The experimental computer is a Macbook Pro with serious heating phenomenon. When the cooling rack is not working, the computer heats up seriously, and there is a serious freeze phenomenon when running large-scale 3D software. After the cooling rack is turned on, the computer fan speed is as good as the body. The temperature of the device is significantly lowered, there is no longer any lagging phenomenon, and the operation is very smooth. Thereby it has been proved that the utility model has remarkable cooling auxiliary effect on notebook computers.
