Description

Integrated liquid cooling system

The present invention relates to the field of liquid cooling systems, and particularly relates to an integrated liquid cooling system, and is mainly applied to a projection device.

In the light projection device, as the brightness of the projection device increases, the power density of the power component becomes larger and larger, and the size of the whole machine and the noise requirement limit, the conventional natural convection and air forced convection heat dissipation method can not meet the requirements. As a mature heat dissipation technology, liquid cooling and heat dissipation, with good heat dissipation and quietness, have been applied to high lumen projection devices.

However, the existing liquid-cooled heat sink has a large volume and a large number of connection points, which makes it impossible to miniaturize the device, and there are too many connection points, and the possibility of coolant leakage increases. Specifically, as shown in FIG. 1, the prior art liquid-cooled heat exchanger includes a water tank 101, a water pipe 102, a pump 103, a heat exchanger 104, a fan 105, and a water-cooling plate 106.

The water-cooling plate 106 absorbs the heat of the heat source, and carries the heat away through the water-cooling liquid flowing through the water-cooling plate 106. The water-cooled liquid is driven by the pump 103, and then flows through the water tank 101, the pump 103, and the heat exchanger 104, and After the fan 105 is cooled by the convection of the heat exchanger 104, it is circulated back to the water-cooling plate 106. The main function of the water tank 101 is to facilitate the filling of the water cooling liquid, the storage of the cooling liquid, and the shortening of the emptying time of the liquid cooling system.

The existing liquid cooling system has a separate water tank, the water tank needs to occupy the system space, the water tank is connected with the heat exchanger, the water tank and the pump through the water pipe, the cost is high, and the system reliability is due to the large number of transfer nodes in the whole system ( The risk of leakage increases.

Further, the water tank is one, and the water tank and the heat exchanger are arranged side by side.

In other embodiments, there are two water tanks, and two water tanks are respectively disposed on both sides of the heat exchanger.

Further, the water outlet of the aggregate is connected to the water inlet of the pump through the water pipe, and the water outlet of the pump is connected to the water inlet of the water cooling plate through the water pipe, and the water outlet of the water cooling plate is connected to the water inlet of the aggregate through the water pipe.

Further, a fan mounted on the heat exchanger is used to carry away heat flowing into the air surrounding the heat exchanger.

Further, the heat exchanger includes a heat dissipation surface, and the fan is mounted on the heat dissipation surface.

Further, the number of water-cooled plates is two.

In another aspect, an embodiment further provides a projection device including a chassis and a light source heat dissipation plate, and the integrated liquid cooling system described above, wherein the integrated liquid cooling system is installed in the chassis, and the water cooling plate and the light source dissipate heat. The plates are attached together.

According to the integrated liquid cooling system and the projection device of the above embodiment, since the water tank and the heat exchanger of the integrated liquid cooling system are of an integrated structure, the space occupied by the water tank is small, and the liquid cooling system is installed in the projection device.
