Mounting structure for sensor attached to heat exchanger

Abstract

A mounting structure is provided, for a sensor which is attached to a heat exchanger. An evaporator that is utilized in a vehicular air conditioning apparatus is equipped with a detection sensor, which is capable of detecting the surface temperature of the evaporator. In the detection sensor, a main body portion thereof on which the detector is provided is inserted between fins of the evaporator. After a cable is made to extend to a cable guide disposed on a side portion of a casing, the cable is retained by the cable guide.

1 . A mounting structure for a sensor attached to a heat exchanger in a vehicular air conditioning apparatus installed in a vehicle, the heat exchanger cooling or heating air supplied to a passage of a casing for blowing the air at a predetermined temperature into a vehicle compartment, and the sensor carrying out temperature detection of the heat exchanger,
 the sensor comprising a detector attached with respect to the heat exchanger for carrying out detection of temperature of the heat exchanger, and a cable connected to the detector, wherein a guide member is formed in the casing, the guide member restricts a path of the cable and is capable of retaining the cable.   
     
     
         2 . The mounting structure according to  claim 1 , the guide member further comprising:
 a base portion joined to the casing; and   a wall portion which is upstanding with respect to the base portion,   wherein, on the wall portion, a retainer is provided, which is capable of retaining the cable together with the base portion and the wall portion.   
     
     
         3 . The mounting structure according to  claim 1 , wherein the guide member is flexibly disposed with respect to the casing. 
     
     
         4 . The mounting structure according to  claim 1 , wherein the guide member is disposed to one side of the heat exchanger, and is formed substantially parallel to a vertical direction of the casing. 
     
     
         5 . The mounting structure according to  claim 1 , wherein the guide member is disposed in an opening that opens on a side portion of the casing for accommodating the heat exchanger in the interior of the casing. 
     
     
         6 . The mounting structure according to  claim 2 , wherein the retainer retains the cable in a displaceable manner along an axial direction of the cable, while restricting displacement in a radial direction of the cable. 
     
     
         7 . The mounting structure according to  claim 2 , wherein the wall portion comprises a pair of wall portions disposed with respect to the base portion, the retainer being disposed on one of the wall portions and distanced from the base portion. 
     
     
         8 . The mounting structure according to  claim 1 , wherein the guide member is formed with a U-shape in cross section from a base portion joined to the casing and wall portions which are upstanding with respect to the base portion.
