VSEngineering Contradiction Analysis

1Temperature

If conventional heat dissipation structures are used in neutron beam generating devices, then the structure is simple, but the heat dissipation efficiency is insufficient causing target material damage

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidstructure complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The heat dissipation structure is divided into multiple functional components: a housing with fluid channel, a target mounted on the housing, and a connecting structure with bevel surfaces. This segmentation allows each component to perform its specific function optimally while contributing to overall heat dissipation efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting structure incorporates first and second bevel surfaces that redirect fluid flow from a horizontal direction to a vertical direction toward the target. This dimensional change in fluid flow path enhances heat dissipation by directing coolant precisely where heat generation occurs.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Temperature

If fluid flow is distributed uniformly in the housing, then the fluid channel is simple, but the heat removal effect at the target center is insufficient

Engineering Contradiction:
Improveheat removal effectVSAvoidfluid channel complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The bevel surfaces are strategically positioned on the connecting structure to concentrate fluid flow specifically at the center of the housing where the target is mounted. This local concentration of fluid flow maximizes heat removal effectiveness at the critical heat generation zone.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The connecting structure with bevel surfaces acts as an intermediary component between the fluid channel and the target. It redirects and concentrates the fluid flow, serving as a mediator that enhances the interaction between the coolant and the target surface for improved heat dissipation.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A heat dissipation structure includes a housing. The housing has opposing upper and lower surfaces, and a fluid channel between the upper surface and the lower surface. The fluid channel is configured to allow a fluid to pass through, and the fluid channel includes an inlet buffer tank, an outlet buffer tank and a connecting structure. The inlet buffer tank has opposing first inner wall and second inner wall surfaces. The outlet buffer tank has opposing first inner wall and second inner wall surfaces, and the second inner wall surface is closer to the inlet buffer tank than the first inner wall surface. The connecting structure is disposed on the inlet buffer tank and the outlet buffer tank, in which the connecting structure has a first bevel surface and a second bevel surface connected to the upper surface of the housing.
