Temperature detection device for the passenger compartment of a vehicle
The invention relates to a temperature detection device ( 1 ) for detecting the temperature (Ta) of the air (A) in the passenger compartment ( 100 ) of a vehicle, that comprises at least one temperature sensor ( 2 ) provided in an air duct ( 4 ) having a first portion ( 5 ), said air duct ( 4 ) being in aeraulic communication with the air of the (A) of the passenger compartment ( 100 ) through said first portion ( 5 ). The temperature detection device ( 1 ) includes means capable of preventing the direct influence of solar rays (RS) on the temperature sensor ( 2 ).
1. A temperature detection device for detecting a temperature of air in a passenger compartment of a vehicle, comprising:
at least two temperature sensors housed in an air duct having a first portion, wherein the air duct is in aeraulic communication with the air of the passenger compartment through the first portion,
wherein the first portion has a shape of a grid to prevent the direct influence of solar rays on the at least two temperature sensors, and
wherein the at least two temperature sensors are fixed onto an electronic card that is partially housed in the air duct.
2. The temperature detection device as claimed in claim 1 , wherein one of the at least two temperature sensors is spaced apart from the first portion by a distance of between 1 and 10 mm.
3. The temperature detection device as claimed in claim 1 , wherein the first portion of said air duct is housed in a façade.
4. The temperature detection device as claimed in claim 3 , wherein the grid is an integral part of the façade.
5. The temperature detection device as claimed in claim 3 , wherein the air duct is arranged vertically relative to the façade.
6. The temperature detection device as claimed in claim 1 , wherein the air duct is open at both its ends.
7. The temperature detection device as claimed in claim 1 , wherein the air duct has a length of between 10 and 100 mm and a width of between 10 and 30 mm.
8. The temperature detection device as claimed in claim 1 , wherein the at least two sensors are thermally coupled.
9. The temperature detection device as claimed in claim 1 , wherein a first of the at least two temperature sensors is spaced apart from a second of the at least two temperature sensors by a distance of between 5 and 30 mm so as to measure two different temperatures.
10. The temperature detection device as claimed in claim 9 , wherein the first temperature sensor is located alongside a first end of the air duct and the second temperature sensor is located alongside a second end of the air duct.
11. The temperature detection device as claimed in claim 10 , wherein the electronic card comprises a first connector linked via connecting wires to the at least two temperature sensors.
12. The temperature detection device as claimed in claim 11 , wherein the electronic card on which the at least two temperature sensors are fixed is operatively connected to the main electronic card via a second connector.
13. The temperature detection device as claimed in claim 12 , wherein the second end is open and a portion of the electronic card receiving the first connector projects from the air duct at a level of the open second end.
14. The temperature detection device as claimed in claim 1 , wherein the temperature detection device is part of a control panel.
15. The temperature detection device as claimed in claim 14 , further comprising a main electronic card, wherein a distance between a second end of the air duct and the main electronic card is between 1 and 20 mm.
