Solution Overview
Problem
Existing evaporators are inefficient in providing adequate cooling for objects with complex outer shapes lacking a single large flat surface, as they fail to establish an optimal thermal connection and sufficient cooling capacity.
Innovation Solution
A multiport tube evaporator with angled heat receiving surfaces, allowing flexible alignment and contact with multiple surfaces of an object, is designed to efficiently follow the shape of the object and enhance cooling capacity by using a multiport tube with separate flow channels and metal plates that can be bent to form multiple evaporator sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single flat surface evaporator is used, then the structure is simple, but the cooling capacity is insufficient for objects with complex shapes
Solution Approach 1:
The evaporator is divided into multiple evaporator sections (first evaporator section with first heat receiving surface, second evaporator section with second heat receiving surface) that can be independently oriented. Each section can contact different surfaces of the object to be cooled, allowing the evaporator to adapt to complex shapes while maintaining adequate cooling capacity across multiple surfaces.
2Reliability
If multiple evaporator sections are added to contact different surfaces, then the cooling capacity improves, but the device complexity increases
Solution Approach 1:
Multiple evaporator sections are integrated into a single evaporator body structure, sharing common support and connection mechanisms. The first and second evaporator sections are combined within one evaporator assembly, reducing the need for separate components while maintaining the ability to contact multiple surfaces of the object.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The evaporator effectively dissipates heat from objects with complex shapes by providing a large boiling surface and optimal fluid flow distribution, eliminating the need for separate thermal pads and enabling efficient cooling of multiple surfaces without the need for a pump-driven circulation system.
Implementation Method 1
heat generated by an object is efficiently passed to an evaporator contacting this object
Implementation Method 2
the evaporator should have a sufficient cooling capacity to remove the heat load generated by the object

AI summary
The invention relates to an evaporator comprising an inlet (3) in a lower manifold (2), an outlet (5) in an upper manifold (4), and a multiport tube (1) extending between the lower manifold and the upper manifold, the multiport tube providing a flow path between the lower (2) manifold and the upper manifold (4). To obtain a simple and efficient evaporator, one of the outer side walls (10) of the multiport tube (1) is provided with a first evaporator section (7) with a first heat receiving surface (13) and a second evaporator section (8) with a second heat receiving surface (14), the first and second evaporator sections (7, 8) passing a heat load received via the respective first and second heat receiving surfaces (13, 14) to a fluid in said multiport tube (1), and the first and second heat receiving surfaces (13, 14) form an angle (27) with each other to align with and contact different surfaces of an object to be cooled.
