Temperature detection device for a vehicle heater
First Claim
1. A temperature detection device for a vehicle heater for detecting a fluid temperature, the temperature detection device comprising:
- a temperature sensor; and
a contact element with a first side, around which the fluid can flow in at least some sections, and with a second side facing away from the first side, wherein the temperature sensor is configured as a radiation sensor and wherein the contact element is arranged relative to the temperature sensor such that at least a part of the radiation emitted from the second side of the contact element can be received by the temperature sensor, wherein the contact element has a contact surface formation comprising a projection on the first side.

Abstract
A temperature detection device (10) for a vehicle heater detects a fluid temperature. The device includes a temperature sensor (12) as well as a contact element (14) with a first side (16), around which the fluid can flow in at least some sections, and with a second side (18) facing away from the first side (16). The temperature sensor (12) is configured as a radiation sensor. The contact element (14) is arranged relative to the temperature sensor (12) such that at least a part of the radiation emitted from the second side (18) of the contact element (14) can be received by the temperature sensor (12).
