Ultraviolet Irradiator Cooling and Filter Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultraviolet irradiators face issues with maintaining proper internal temperatures and efficient ultraviolet light transmission due to the deterioration of colored glass filters, leading to increased running costs and the need for simultaneous replacement of filters and water-cooling jackets.
Innovation Solution
An ultraviolet irradiator design featuring a housing with a water-cooling jacket, a reflection plate, and a heat withdrawing mechanism, along with a heat transfer member and air blower for efficient cooling, allowing for targeted ultraviolet light emission without a colored glass filter, and enabling the ultraviolet lamp to be freely inserted and removed without dismounting the irradiator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the colored glass filter is mounted in the water-cooling jacket to cool the ultraviolet lamp, then the ultraviolet lamp can be cooled effectively, but the colored glass filter deteriorates due to ultraviolet light exposure and must be replaced together with the water-cooling jacket
Solution Approach 1:
The patent separates the colored glass filter from the water-cooling jacket by introducing a filter holder that can be independently removed. This allows the filter to be segmented as a separate replaceable component while the water-cooling jacket remains intact, resolving the contradiction by enabling independent replacement of the deteriorated filter without discarding the functional cooling jacket.
Solution Approach 2:
The colored glass filter is extracted from the unified water-cooling jacket structure and placed in a separate filter holder. This extraction allows the filter to be removed and replaced independently, solving the problem where the filter's deterioration previously forced replacement of the entire water-cooling jacket assembly.
2Reliability
If the colored glass filter is fixed in the water-cooling jacket to prevent water leakage, then water sealing is improved, but the filter and water-cooling jacket become unified requiring simultaneous replacement
Solution Approach 1:
The filter holder is designed as a separate component that interfaces with the water-cooling jacket through a sealing structure. This segmentation maintains water sealing integrity while allowing the filter holder and filter to be removed and replaced as a separate unit, providing maintenance flexibility without compromising sealing reliability.
Solution Approach 2:
The filter holder acts as an intermediary component between the colored glass filter and the water-cooling jacket. It provides the sealing function to prevent water leakage while enabling independent removal and replacement of the filter, thus resolving the contradiction between maintaining water sealing and enabling easy maintenance.
3Illumination intensity
If the reflection plate is used to reflect ultraviolet light, then ultraviolet illuminance is improved, but the reflection plate absorbs heat and its temperature increases
Solution Approach 1:
A heat transfer member is introduced as an intermediary between the reflection plate and the housing. This member conducts heat away from the reflection plate to the housing, allowing the reflection plate to maintain high ultraviolet reflectivity and illuminance while its temperature is actively managed and reduced through thermal conduction to the surrounding structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively maintains proper internal temperatures, prevents thermal damage to the reflection plate, and reduces running costs by allowing the ultraviolet lamp to be exchanged independently, while ensuring efficient ultraviolet light transmission and illuminance distribution.
Implementation Method 1
a water-cooling jacket in which the ultraviolet lamp is mounted
Implementation Method 2
a reflection plate that reflects light emitted from the ultraviolet lamp
Implementation Method 3
a heat transfer member that transfers ambient heat in the housing to the heat withdrawing mechanism
Implementation Method 4
a heat withdrawing mechanism that withdraws heat of the reflection plate and discharges the heat to the outside of the housing

AI summary
An ultraviolet irradiator including a housing having an ultraviolet irradiation port through which the target is irradiated with the ultraviolet light, an ultraviolet lamp that emits ultraviolet light, a water-cooling jacket in which the ultraviolet lamp is mounted, a reflection plate that reflects light emitted from the ultraviolet lamp, the ultraviolet lamp, the water-cooling jacket and the reflection plate being mounted in the housing, and ultraviolet light emitted directly from the ultraviolet lamp and reflection light reflected from the reflection plate being irradiated to the outside of the housing, a heat withdrawing mechanism that withdraws heat of the reflection plate and discharges the heat to the outside of the housing; and a heat transfer member that transfers ambient heat in the housing to the heat withdrawing mechanism so that the heat withdrawing mechanism withdraws the ambient heat.
