Heater with beaker-shaped heat exchanger has tubular wall narrowing from burner towards floor at step from first essentially straight section(s) to second essentially straight section(s)

摘要

The device has a burner and a beaker-shaped heat exchanger (10) with a floor opposite the burner and an essentially tubular wall (14) attached to the floor and extending to the burner. The tubular wall narrows from the burner towards the floor at a step from at least one first essentially straight section (20) to at least one second essentially straight section. Independent claims are also included for the following: a heat exchanger for a heater and a vehicle with a heater.
