Solution Overview

Problem

Conventional reactor units have limited cooling capabilities, primarily relying on heat radiation through the atmosphere from one surface, which restricts the cooling efficiency and increases the temperature of the reactor core, thereby limiting output.

Innovation Solution

The reactor unit incorporates a cooler with a metal plate covering the opposite surface of the reactor, creating a heat radiation path to enhance cooling, and an optional heat radiating member with elastic properties to improve heat conduction and vibration damping.

1Temperature

If the reactor is cooled only through heat radiation from one surface to the cooler, then the cooling system is simple, but the cooling capability is insufficient

Engineering Contradiction:

Solution Approach 1:

The invention transitions from single-sided cooling to dual-sided cooling by adding a metal plate that enables heat radiation from the second surface of the reactor. This dimensional expansion of the cooling interface significantly enhances heat dissipation capability without requiring a complete redesign of the cooler structure.

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

Solution Approach 2:

The cooler structure is segmented into distinct functional components: the reactor cooling surface for direct heat radiation, and the metal plate that creates an additional heat radiation path. This segmentation allows each component to optimize its specific cooling function while working together to achieve superior overall cooling performance.

Inventive Principle:
Principle #1Segmentation

2Productivity

If heat radiation path is extended to the second surface of the reactor, then the cooling efficiency increases, but the temperature difference between surfaces must be managed

Solution Approach 1:

The invention changes the thermal parameters of the system by introducing a metal plate with specific thermal conductivity properties. This enables controlled heat transfer from the second surface, allowing the system to operate at higher overall power levels while managing surface temperature differences through the thermal characteristics of the metal plate.

Solution Approach 1:

The heat radiating member with elastic force serves as an intermediary element between the reactor and the cooler. It enhances thermal contact and heat conduction efficiency through its elastic properties, while also providing vibration damping. This intermediary component bridges the thermal gap more effectively than rigid direct contact alone.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The heat radiating member performs multiple functions simultaneously: it enhances heat conduction from the reactor to the cooler, provides vibration damping through its elastic properties, and maintains thermal contact under varying operational conditions. This multi-functionality reduces the need for separate components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
