Solution Overview
Problem
Existing electrical appliances face challenges in adapting to changing cooling requirements without significant design or construction modifications to the machine module.
Innovation Solution
The electrical appliance features a machine module with three cooling fluid connection zones, allowing for various cooling techniques to be implemented by adjusting the cooler module, such as open air or closed air-water cooling, without altering the machine housing, using a standardized design for different cooling methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cooling system is completely redesigned when cooling requirements change, then the cooling effectiveness is improved, but the construction and design effort increases significantly
Solution Approach 1:
The machine housing is designed with multiple cooling fluid connection zones (first, second, and third connection zones) that can accommodate different cooler modules. This universal design allows the same machine housing to support various cooling techniques (open air cooling, closed air cooling with air-air heat exchanger, closed air cooling with air-water heat exchanger, etc.) without requiring redesign, thereby resolving the contradiction between cooling effectiveness and construction effort.
2Adaptability or versatility
If different cooling techniques are implemented with the same machine housing, then the adaptability is improved, but the fluid flow path complexity increases
Solution Approach 1:
The cooling fluid connection zones are segmented into distinct locations: first connection zone at one end of the machine housing, second connection zone at the other end, and third connection zone in a central section. This segmentation allows different cooler modules to be connected to specific zones based on cooling requirements, enabling adaptability while maintaining simple, organized fluid flow paths without excessive complexity.

AI summary
The invention relates to an electric appliance (1) which comprises a machine module (2) provided with an electric machine (3) comprising a stator (4) and a rotor. A machine housing (7) of the machine module (2) receives the electric machine (3). A cooling module (19) comprises a cooling housing (21), which is fluidically connected to the machine housing (7) by means of a first cooling fluid connection area (20) in a housing wall (17) of the machine housing (7) and to at least one second cooling fluid connection area (23) in the housing wall (17) of the machine housing (7). The inside of the machine housing (7) can be fluidically connected to the inside of the cooling housing (21) in one section of the housing wall (17), which is oriented towards the cooling housing (21), by means of at least one third cooling fluid connection area (25) comprising at least one cooling fluid through-opening (26). Various cooling module variants can use said third cooling fluid connection area (25) when other cooling module variants, which can be used in exchange with the cooling module (19) in the machine module (2), do not use the third cooling fluid connection area (25). As a result, an electric appliance (1), a machine module (2) therefore and a set comprising a plurality of different cooling modules, which can meet altered cooling requirements having reduced structural and constructural costs, can be produced.
