HEAT EXCHANGER Russian patent published in 2019 - IPC B60H1/22 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat exchangers of vehicle heaters. Heat exchange apparatus comprises housing (16) with outer (24) and inner (30) walls. Outer (24) and inner (30) walls envelope flow path (36) for heat transfer medium, which is passed by heat transfer medium (M). In outer wall (24) there is at least one mounting opening (42) for sensor. Sensor (40) is installed in at least one mounting hole (42) tightly, movably, with possibility of contact with flow space (36) for heat transfer medium by means of section (50) for contact with flow space and resting on inner wall. Sensor (40) is provided with pre-tensioning mechanism (52) for imparting a load to it when it is supported on inner wall (30). Pre-tensioning mechanism (52) is fixed in fixation area (54) relative to outer housing (58) enclosing heat exchange apparatus (22) at least in separate sections, and applies load on load application section (56) to attachment sensor (40) on inner wall (30).

EFFECT: simple and reliable method of positioning a sensor in contact with a flow space for a heat transfer medium.
