Abstract
A heat exchanger arrangement (10), especially for a fuel-operated vehicle heater, includes an outer pot-shaped housing (12) having an outer bottom wall (16) and an outer circumferential wall (18) extending along a longitudinal axis (L). An inner pot shaped housing (14) has an inner bottom wall (20) and an inner circumferential wall (22) extending along the longitudinal axis (L). A flow space (24) for fluid whose temperature is to be regulated is formed between the inner housing (16) and the outer housing (12). At least one liquid uptake volume (46, 48) for taking up liquid condensed in the inner housing (14).
Claims20
A heat exchanger arrangement for a fuel-operated vehicle heater, the heat exchanger comprising:
- an outer pot shaped housing having an outer bottom wall and an outer circumferential wall extending along a longitudinal axis;
- an inner pot shaped housing having an inner bottom wall and an inner circumferential wall extending along the longitudinal axis, wherein a flow space is formed, for a fluid for which a temperature is to be regulated, between the inner housing and the outer housing;
- and
- at least one liquid uptake area for taking up liquid condensed in the inner housing.
A vehicle heater, comprising a heat exchanger arrangement, the heat exchanger arrangement comprising:
- an outer pot shaped housing having an outer bottom wall and an outer circumferential wall extending along a longitudinal axis;
- an inner pot shaped housing having an inner bottom wall and an inner circumferential wall extending along the longitudinal axis, wherein a flow space is formed, for a fluid for which a temperature is to be regulated, between the inner housing and the outer housing;
- and
- at least one liquid uptake area for taking up liquid condensed in the inner housing.
A heat exchanger arrangement comprising:
- an outer housing having an outer bottom wall and an outer circumferential wall extending along a longitudinal axis;
- an inner housing having an inner bottom wall and an inner circumferential wall extending along the longitudinal axis, wherein a flow space is formed, for a fluid for which a temperature is to be regulated, between the inner housing and the outer housing, the inner housing having an inner circumferential wall defining a space to be exposed to combustion gas;
- and
- a liquid uptake volume for taking up liquid condensed in the inner housing, the liquid uptake volume being in fluid communication, through an opening in the inner housing with the space to be exposed to combustion gas.
