Abstract
A motor vehicle fuel pump cover is provided for covering a fuel guide region of a motor vehicle fuel pump by way of a cover housing. A phase change core is received in the cover housing. The phase change core is designed to change the phase state thereof while receiving thermal energy from the fuel guide region. The phase change core is designed for phase change at a temperature of more than 60° C.
Claims10
A motor vehicle fuel pump cover for covering a fuel guide region of a motor vehicle fuel pump, comprising:
- a cover housing;
- and
- a phase change core accommodated in the cover housing, wherein
- the phase change core is positioned, relative to the fuel guide region, at such a distance therefrom so as to change its phase state by taking up thermal energy directly from the fuel guide region, and
- the phase change core is configured to change its phase at a temperature of more than 60° C.
A method for producing a motor vehicle fuel pump cover, the method comprising the steps of:
- providing a phase change core, wherein the phase change core is positioned, relative to a fuel guide region, at such a distance therefrom so as to change its phase state by taking up thermal energy directly from the fuel guide region, and further wherein the phase core changes phase at a temperature greater than 60° C.;
- partially or completely encasing the phase change core with a cover housing;
- and
- shaping the motor vehicle fuel pump cover.
