Problems solved by technology

[0005] However, when installing the temperature sensor 2 using the above-mentioned prior art, it is necessary to pre-install a plurality of clamping members 7a, 7b on the evaporator 1 in order to route its cables 5 in a desired path, which is cumbersome and increases the number of parts , while increasing the number of steps to assemble the device
In addition, since the clamps 7a, 7b are attached by being inserted into the fins 6, this can for example cause damage to the fins 6, raising concerns that the performance of the heat exchanger will deteriorate

Embodiment Construction

[0018] exist figure 1 In , reference numeral 10 denotes a vehicle air conditioner having a heat exchanger therein on which a sensor according to an embodiment of the present invention is mounted.

[0019] Such as figure 1 and figure 2 As shown, the vehicle air conditioner 10 includes a housing 12 composed of corresponding air ducts, an evaporator 14 (heat exchanger) disposed inside the housing 12 for cooling air, and a heater core (not shown) for heating the air. Out) and a duct 18 installed at the opening 16 of the housing 12, the duct 18 guides the air supplied from the fan to flow into the inside of the housing 12. In addition, the inside of the housing 12 is provided with an air mix door (not shown) and a plurality of air injection hole doors, the air introduced into the housing 12 is heat-exchanged by the evaporator 14 and the heater core through the air mix door, and the air mix door The plurality of nozzle doors selectively supplies the mixed air into the passenge...

Abstract

A mounting structure is provided, for a sensor which is attached to a heat exchanger. An evaporator (14) that is utilized in a vehicular air conditioning apparatus (10) is equipped with a detection sensor (46), which is capable of detecting the surface temperature of the evaporator (14). In the detection sensor (46), a main body portion (48) thereof on which the detector (56) is provided is inserted between fins (38) of the evaporator (14). After a cable (50) is made to extend to a cable guide (24) disposed on a side portion of a casing (12), the cable (50) is retained by the cable guide (24).

Description

technical field [0001] The present invention relates to a mounting structure for a sensor attached to, for example, a heat exchanger provided in a vehicle air conditioner, the sensor being provided for the purpose of detecting the temperature of air passing through the heat exchanger. Background technique [0002] Hitherto, in a vehicle air conditioner installed in a vehicle such as an automobile, air is drawn into a housing by a fan, the air cooled by an evaporator (heat exchanger) serving as a cooling device and used as a heating device After the air heated by the heater core is mixed in the casing at a predetermined mixing ratio, the air is selectively ejected from the air injection holes provided in the vehicle compartment, thereby adjusting the temperature and humidity in the vehicle compartment. [0003] Such as Figure 6 As shown, on the evaporator 1 disclosed in Japanese Laid-Open Patent Publication No. 2006-017406, a surface for detecting the evaporator 1 is attache...
