Improvements through improved thermal efficiency are less common. Therefore, the common practice in the industry is to mix heat dissipation, mix the heat from the optical machine light source and the heat on the LCD screen, and discharge it out of the machine through the fan on the radiator; while the heat inside the optical machine is mostly enclosed in the light cone , as the temperature in the optical machine increases, it is emitted through radiation. As a result, excessive heat can be concentrated on the LCD screen.

Below in conjunction with Fig. 1 the utility model is described in detail.

The utility model aims at the defect of poor heat dissipation effect existing in the existing optical projector, and discloses a projector device with efficient heat dissipation capability, which includes a chassis 2d and an upper cover 1 arranged above the chassis 2d. An optical assembly 3a is arranged on the inner side of the chassis 2d, a light source 4a matching it is arranged on the rear side of the optical assembly 3a, and a power supply 7a electrically connected to it is arranged on the side of the optical assembly 3a. The side of the light source 4a away from the optical assembly 3a is provided with a radiator main body 5a, and a radiator heat pipe 5b matching it is provided on the radiator main body 5a, and the radiator main body 5a is close to the A cooling fan 6a is provided on one side of the power supply 7a, a first air inlet 2b is provided on the chassis 2d on the side away from the optical assembly 3a of the power supply 7a, and a first air inlet 2b is provided on the side away from the optical assembly 3a. A second air inlet 2a is provided on the case 2d, and an air outlet 2c is provided on the case 2d at the rear side of the cooling fan 6a. In the utility model, the existing optical components can be used to make the radiator cylinder and the radiator heat pipe cooperate with each other. In the utility model, the low-temperature air flows into the cabinet along the directions A and B in the figure, and the hot air after heat exchange is discharged along the direction C in the figure.

When the fan is turned on, under the action of the fan, the interior of the chassis will quickly become a negative pressure state. At this time, the airflow will quickly enter the interior of the chassis along the first air inlet and the second air inlet. The components and power supply flow to the fan, and heat exchange with the optical components and power supply is carried out during the airflow process, thereby realizing rapid cooling of the power supply and optical components.

Since the utility model is respectively provided with a first air inlet and a second air inlet on both sides of the power supply and the optical assembly, the cold air flow can flow through the power supply and the optical assembly to the inside of the chassis respectively. Under the action of the cooling fan, the hot air flows out of the chassis through the air flow, so that the temperature inside the chassis can be quickly cooled.

Example 1:

In order to improve the efficiency of hot air output and correspondingly improve the heat dissipation efficiency of the cooling fan, in this embodiment, preferably, a radiator fin 5c is provided on the side of the radiator main body 5a close to the radiator fan 6a. The radiator fins 5c are located between the cooling fan 6a and the air outlet 2c. In this embodiment, the heat dissipation efficiency of the heat dissipation fan can be increased through the heat dissipation fins arranged on the rear side of the heat dissipation fan, so that heat exchange can be performed quickly during the high-speed wind flow process, which helps to improve the heat dissipation efficiency.

In order to improve the efficiency of cold air input, in this embodiment, there are at least two groups of the first air inlets 2b and the second air inlets 2a respectively. In this embodiment, the number of the first air inlet and the second air inlet can be determined according to the structure of the chassis. By setting multiple sets of first air inlets and second air inlets, the rapid input of cold air can be realized. During the rapid input of cold air, the cold air can exchange heat with the optical components and power supply, which can greatly improve the heat exchange efficiency of the overall structure.

Example 2:

A partition 7b is provided between the optical assembly 3a and the power supply 7a. By setting the partition, the power supply and the optical assembly can be separated, and the power supply and the optical assembly will not affect each other during use. Since the power supply and the optical components may generate heat at different speeds during use, in this embodiment, the partitions are used to place the two in the two cavities respectively, which can avoid heat transfer between the power supply and the optical components. When the fan is running, through The first air inlet and the second air inlet respectively cool the power supply and the optical assembly, which can simultaneously realize the cooling of the power supply and the optical assembly, and at the same time help to prolong the service life of the power supply and the optical assembly.

Further preferably, in this embodiment, the partition 7b is located in the front middle of the cooling fan 6a. When the cooling fan is in use, by placing the cooling fan on the back side of the partition, the cooling fan can simultaneously exhaust the cavities on both sides of the partition, so that during the flow of cold air on both sides, it can simultaneously cool down the power supply and optical components. During the air flow on both sides, the hot air after heat exchange will not flow to the other side, which can further reduce the heat transfer between the optical components and the power supply. By placing the cooling fan behind the partition, when the cooling fan is running, the optical components and power supplies on both sides of the partition can be quickly cooled, and the power supply and optical components can be cooled quickly while the power supply and optical components are not There will be mutual interference, making it more effective in cooling.
