Solution Overview

Problem

In solid-state light source projection systems, conventional heat dissipation methods often increase system noise and cost due to the need for multiple fans, and placement of radiators either leads to reduced heat dissipation performance or increased fan usage.

Innovation Solution

A projection device design featuring a housing divided into two spaces with the radiator in one space and a heat dissipation plate in the other, allowing for independent cooling air flows that directly cool the radiator and discharge high-temperature air, improving heat dissipation efficiency while reducing the need for multiple fans.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the radiator is placed at the air inlet of the system, then the heat dissipation path is extended, but the fan usage increases and system noise increases

Engineering Contradiction:

Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The housing is divided into a first space and a second space using a spacer plate. The first space houses the radiator with its dedicated air inlet and air outlet, while the second space houses other components. This segmentation allows the radiator to have an independent heat dissipation path, eliminating the need for additional fans and reducing system noise.

AI summary

A projection device includes a housing, a spacer plate, and a heat dissipation module. The spacer plate is disposed in the housing to divide the housing into a first space and a second space. The heat dissipation module includes a radiator, a heat dissipation plate, a driving element, and a tube. The radiator is located in the first space, and the heat dissipation plate is located in the second space. The first space has a first air inlet and a first air outlet. A first cooling air flow enters the first space from the first air inlet, flows through the radiator, and is discharged from the first air outlet. The second space has a second air inlet and a second air outlet. A second cooling air flow enters the second space from the second air inlet, and is discharged from the second air outlet.
