Active Energy Irradiation Cooling Duct for Housing Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The housing of active energy irradiation devices overheats due to heat from air passing through the heatsink, which is a concern in existing designs.
Innovation Solution
The device incorporates an air presence region around the duct inside the housing, preventing direct contact between the duct and the housing, and introduces air into a low-temperature space before it passes through the heatsink, using a duct with a specific shape and intake filter to suppress heat propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air is introduced into the housing and passes through the heatsink, then cooling effect is achieved, but the housing becomes overheated due to heat transfer from the air
Solution Approach 1:
A heat-resistant material layer is introduced as an intermediary between the heatsink and the housing. This layer acts as a thermal barrier that prevents direct heat transfer from the heated air passing through the heatsink to the housing, thereby solving the contradiction between achieving cooling effect and preventing housing overheating.
Solution Approach 2:
A thin heat-resistant film or coating is applied to the housing surface in contact with the heatsink. This thin layer provides thermal insulation while maintaining the structural integrity and compact design of the housing, effectively reducing heat transfer without adding significant bulk.
2Device complexity
If the duct is placed directly against the housing for compact design, then device complexity is reduced, but heat propagation to the housing increases
Solution Approach 1:
The heat-resistant material layer serves as a mediator between the duct and the housing, allowing the duct to be positioned closely to the housing for compact design while preventing harmful heat propagation. This intermediary layer enables both structural simplicity and thermal protection simultaneously.
Solution Approach 2:
The thermal conductivity parameter of the interface between the duct and housing is changed by introducing a heat-resistant material layer. This changes the thermal interaction from direct high-conductivity contact to low-conductivity thermal coupling, reducing heat propagation while maintaining spatial proximity.

AI summary
An active energy irradiation device includes: a plurality of active energy irradiation units; an air-cooled heatsink thermally connected to the active energy irradiation units; a housing that houses the active energy irradiation units and the heatsink; an intake unit that introduces air into the housing; an exhaust unit that discharges the air to an outside of the housing; and a duct provided between the heatsink and the exhaust unit inside the housing, and allowing the air, which has passed through the heatsink, to flow through to the exhaust unit. An air presence region where the air exists before passing through the heatsink is provided around the duct inside the housing so as to surround the duct.
