HEAT RESERVOIR COMPRISING A DIFFUSOR PORTION

摘要

The invention relates to a heat reservoir (100) comprising a housing (101), first reservoir elements (102) for storing thermal energy, and an inlet port (103). The first reservoir elements (102) are arranged in the housing (101). The inlet port (103) is coupled to the housing (101) in such a way that a working fluid can flow into the housing (101) through the inlet port (103). The inlet port (103) is provided with an inlet orifice (104) through which the working fluid can flow from the surroundings of the heat reservoir (100) into the inlet port (103). The inlet port (103) includes a diffusor portion (105), the cross-section of which increases in the direction running from the inlet orifice (104) to the housing (101).
