Description
- This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2009-215176 filed on Sep. 17, 2009, of which the contents are incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a mounting structure for a sensor, which is attached, for example, to a heat exchanger that is disposed in a vehicular air conditioning apparatus, and which is provided for the purpose of detecting the temperature of air that has passed through the heat exchanger.
- 2. Description of the Related Art

- As shown in
FIG. 6 , on anevaporator 1, which is disclosed in Japanese Laid-Open Patent Publication No. 2006-017406, there is attached atemperature sensor 2 on a side thereof forming a downstream side of air that passes through theevaporator 1, for detecting the surface temperature of theevaporator 1. Additionally, based on the temperature that is detected by thetemperature sensor 2, control of air conditioning inside the vehicle compartment of the vehicle is carried out. - The
temperature sensor 2 is constituted from ahousing 4 having asensor portion 3, and acable 5 that is connected to a side surface of thehousing 4. Through insertion of thesensor portion 3 betweenfins 6 that make up theevaporator 1, thehousing 4 is fixedly attached to a side surface of theevaporator 1. Further, thecable 5 is connected electrically with respect to a controller or the like installed in the vehicle, and together therewith, the path of thecable 5 is restricted byplural clamp members evaporator 1, whereby thecable 5 is guided to a desired location. - However, using the above-described conventional technique, when the
temperature sensor 2 is mounted, theplural clamp members evaporator 1 beforehand in order to arrange thecable 5 thereof along a desired path, which is cumbersome and increases the number of parts, together with increasing the number of assembly steps required to assemble the apparatus. Further, because theclamp members fins 6, for example, damage to thefins 6 can result, leading to a concern that performance of the heat exchanger will become degraded. - A general object of the present invention is to provide a mounting structure for a sensor that is attached to a heat exchanger, which is capable of reducing the number of parts and assembly steps when the sensor is mounted to the air conditioning apparatus.
- The present invention is characterized by 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 comprises 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, and the guide member restricts a path of the cable and is capable of retaining the cable.
- According to the present invention, in the heat exchanger, which is utilized in a vehicular air conditioner installed in the vehicle, a sensor is installed that detects the temperature of the heat exchanger. A cable, which is connected to the detector of the sensor, is restricted to a desired path and is retained by the guide member, which is formed in the casing of the vehicular air conditioner.
- Accordingly, a cumbersome operation like that of the conventional sensor mounting structure, of attaching each of plural clamp members with respect to the heat exchanger in order to restrict the path of the cable, is no longer necessary. Along therewith, when the sensor is installed, the number of assembly steps can be reduced, together with decreasing the number of parts and associated costs for the mounting structure.
- The above and other objects, features, and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings in which a preferred embodiment of the present invention is shown by way of illustrative example.

Thecable guide 24, for example, is formed from a resin material similar to that of thecasing 12 itself, which is disposed on an end surface of theopening 16 on which theduct 18 is installed. Further, thecable guide 24 is formed so as to project in a substantially horizontal direction oriented toward the center of theopening 16. - Further, as shown in
FIGS. 2 through 4 , thecable guide 24 is made up from a planarshaped base portion 26, which is joined to the end of theopening 16 and projects toward a side of the opening 16, and a pair of first and second guide walls (wall portions) 28, 30, which project with respect to thebase portion 26 toward a direction separating away from theopening 16. Additionally, the first andsecond guide walls base portion 26, and extend in a vertical direction perpendicular to a direction in which thebase portion 26 extends. - Stated otherwise, the first and
second guide walls casing 20, and the first andsecond guide walls base portion 26. More specifically, thecable guide 24 is formed to have a U-shape in cross section from thebase portion 26 and the pair of first andsecond guide walls second guide walls base portion 26 is set to be substantially the same or somewhat larger than the diameter of thecable 50. - The
first guide wall 28 is disposed more toward the central side of the opening 16 than thesecond guide wall 30. A hook member (retainer) 32 capable of retaining thecable 50 of thedetection sensor 46, to be described later, is included on thefirst guide wall 28. - The
hook member 32 is disposed at an end of thefirst guide wall 28 at a position separated maximally from thebase portion 26. Thehook member 32 projects from the end toward the side of thesecond guide wall 30, and is formed so as to extend in a longitudinal direction of thefirst guide wall 28. Additionally, when thecable 50 is retained by thecable guide 24, thehook member 32 is held against and holds the outer circumferential surface of thecable 50, in a state in which thecable 50 abuts against inner wall surfaces of thebase portion 26 and thefirst guide wall 28. - Stated otherwise, the
cable 50 is placed in a state such that roughly half of the outer circumferential surface is retained by thebase portion 26, thefirst guide wall 28 and thehook member 32. - Further, when the
cable 50 is retained by thehook member 32, thecable 50 is retained so as to be displaceable along a longitudinal direction of thecable 50, but wherein displacement of thecable 50 in a direction to separate away from thecable guide 24, i.e., displacement in the radial direction of thecable 50, is restricted. - On the other hand, the
cable guide 24 has a flexible elasticity about a fulcrum where thecable guide 24 is joined with respect to thecasing 12. More specifically, thecable guide 24 is formed such that thebase portion 26 thereof, which is joined to thecasing 12, has a plate thickness (thickness dimension) that enables flexibility, so that thecable guide 24 is tiltable with respect to thecasing 12 by a predetermined angle to the horizontal direction. - Furthermore, in the first divided
casing 20, a cable hole 34 (seeFIG. 1 ) opens at a position upwardly of thecable guide 24, and thecable 50 of the later-describeddetection sensor 46 passes through thecable hole 34 from the interior to the exterior of the first dividedcasing 20. - As shown in
FIGS. 1 , 5A and 5B, theevaporator 14 comprises a plurality oftubes 36 through which a coolant flows,fins 38 which are bent in a wavelike form in a serpentine pattern between thetubes 36, and a pair oftanks tanks 40 a, the coolant is introduced from the exterior through asupply pipe 42, and after the coolant has circulated in the interior of theevaporator 14 through thetubes 36 whereupon heat exchange is performed thereby, the coolant is directed out to the exterior from adischarge pipe 44, which is connected again to thetank 40 a. - More specifically, on the
evaporator 14, theplural tubes 36 andfins 38 are separated mutually by equal distances and are arranged in parallel in the widthwise direction, and thetanks tubes 36 and thefins 38 are formed in a boxlike shape, arranged at upper and lower portions of the evaporator 14 (seeFIG. 1 ). - Further, the
detection sensor 46 is disposed on a side surface of theevaporator 14 in order to detect the surface temperature of theevaporator 14. Thedetection sensor 46 includes amain body portion 48 which is mounted on theevaporator 14, thecable 50 connected to themain body portion 48, and aconnector 52 connected to another end of thecable 50. Thedetection sensor 46 is disposed on a side surface of theevaporator 14, which forms a downstream side thereof when air passes through theevaporator 14 and heat exchange is performed thereon. - A detector 56 (see
FIGS. 5A and 5B ) projects on themain body portion 48 from a lower surface thereof. Thedetector 56 is formed, for example, from a thermistor. Further, thecable 50, which is connected electrically to thedetector 56 in the interior of themain body portion 48, is connected to a side of themain body portion 48. - In addition, the
detector 56 of thedetection sensor 46, which has a projecting columnar shape, is supported on a side surface of theevaporator 14 by insertion thereof between thefins 38 on theevaporator 14. Themain body portion 48 including thedetector 56 is affixed with respect to theevaporator 14. Themain body portion 48 of thedetection sensor 46 is mounted so as to be roughly parallel to thetanks tubes 36. - On the other hand, the
cable 50 is formed with a predetermined length, one end thereof being connected to themain body portion 48, and theconnector 52, which is connected to connection terminals of a non-illustrated controller, being connected to the other end of thecable 50. In addition, in a condition where thedetection sensor 46 is mounted on a side surface of theevaporator 14, thecable 50 extends in a straight line alongside theevaporator 14, i.e., in a substantially horizontal direction, and after insertion through thecable guide 24 formed in the first dividedcasing 20, thecable 50 is directed upwardly. - Further, the
cable 50, after having been guided upward by thecable guide 24, passes through thecable hole 34 formed in the first dividedcasing 20 and is inserted therethrough to the outside. At this time, thecable 50 is fixed in place by being sandwiched and gripped between the opening 16 of the first dividedcasing 20 and theduct 18 that is installed on theopening 16. - The vehicular
air conditioning apparatus 10, having a heat exchanger on which the sensor according to the embodiment of the present invention is mounted, is constructed basically as described above. Next, a method of assembling thedetection sensor 46 and theevaporator 14 shall briefly be described. - Initially, in a state in which the
opening 16 of the first dividedcasing 20 is opened, when theevaporator 14 is arranged inside thecasing 12, thedetection sensor 46 is mounted on a side surface of theevaporator 14 that forms the downstream side thereof. More specifically, thedetection sensor 46 is moved to a region on theevaporator 14 where it is desired to detect the surface temperature, and thedetector 56 thereof is inserted between thefins 38 of theevaporator 14 and fixed there in place. - Next, from the
opening 16, theevaporator 14 together with thedetection sensor 46 is inserted into and housed in the interior of the first dividedcasing 20, and thecable 50 of thedetection sensor 46 is made to extend along one surface side of theevaporator 14 so as to be roughly parallel with thetanks evaporator 14. Additionally, thecable 50, after having been extended to reach thecable guide 24 of the first dividedcasing 20, is inserted therethrough to the outer side of thecable guide 24 that faces toward the exterior of the first dividedcasing 20. Moreover, theevaporator 14 is fixed at a predetermined position in the interior of thecasing 12, which is made up from the first and second dividedcasings - At this time, the
cable 50 is inserted so as to abut against thefirst guide wall 28 and thebase portion 26 that make up thecable guide 24, and further is inserted between thehook member 32 and thebase portion 26 of thecable guide 24. Consequently, thecable 50 is retained reliably and securely in thecable guide 24 via thebase portion 26, thefirst guide wall 28, and thehook member 32. - In addition, after the path of the
cable 50 is changed and bent upward at a right angle by thecable guide 24, thecable 50 extends upwardly and is drawn out to the exterior from thecable hole 34 formed in the first dividedcasing 20. - Lastly, the
duct 18 is installed on theopening 16 of the first dividedcasing 20, and by fitting thereof into theopening 16, a portion of thecable 50 becomes gripped and fixed between theopening 16 and theduct 18. At this time, while being guided by thecable guide 24, thecable 50 is pulled out toward the other end side to which theconnector 52 is connected. In a tensioned state in which a certain amount of tension is applied to thecable 50, thecable 50 is fixed in place by theduct 18. Then, deflection of thecable 50, etc., does not occur, and thus an appropriate condition is obtained. - Then, the
connector 52, which is connected to thecable 50, for example, is connected to connection terminals of a controller that is installed in the vehicle. Accordingly, the surface temperature of theevaporator 14, which is detected by thedetection sensor 46, is output to the controller as detection signals via thecable 50 and theconnector 52. - In the foregoing manner, with the present embodiment, the
detection sensor 46 is mounted with respect to theevaporator 14, which is used in the vehicularair conditioning apparatus 10, such that when the surface temperature of theevaporator 14 is detected, thecable guide 24 is formed beforehand in the vicinity of theopening 16 of the first dividedcasing 20 that makes up the vehicularair conditioning apparatus 10. Owing thereto, when thedetection sensor 46 is installed on theevaporator 14, thecable 50 is guided suitably by thecable guide 24, and can be directed to the exterior of thecasing 12 along a predetermined path. As a result, there is no need for a plurality of clamp members to restrict the path of thecable 50 of thedetection sensor 46, as was necessary in the assembly structure of the conventional art. Along therewith, the number of assembly steps can be reduced, together with decreasing the number of parts and associated costs for thedetection sensor 46. - Further, even in a case where tensile forces are applied to the
cable 50 that is retained by thecable guide 24, for example, by variances in the attachment position of thedetection sensor 46 or by pulling of thecable 50 during the assembly operation, because thecable guide 24 is joined in a flexible manner with respect to an end surface of theopening 16 in the first dividedcasing 20, such tensile forces can suitably be absorbed, and undesirable movements in the position of thedetection sensor 46 can be avoided. Further, faulty operation of thedetector 56 or the like, which is a concern in the case that tension is applied to thedetector 56 via thecable 50, can be avoided. - Furthermore, the
cable guide 24 includes the pair of first andsecond guide walls cable 50 is retained between the first andsecond guide walls cable 50 is suitably held by the pair of first andsecond guide walls cable 50 from thecable guide 24 can be prevented. - Still further, on the aforementioned
first guide wall 28, since ahook member 32 is provided, which is cable of retaining thecable 50 under a condition in which thecable 50 abuts against inner wall surfaces of thebase portion 26 and thefirst guide wall 28, thecable 50 can reliably be retained by thecable guide 24 including thefirst guide wall 28. Moreover, because thehook member 32 retains thecable 50 so as to be displaceable in the longitudinal direction, even in the case that thecable 50 is displaced along the longitudinal direction by variances in the installation position of thedetection sensor 46 or the like, thecable 50 can appropriately be displaced freely under a condition in which thecable 50 is retained by thehook member 32. - More specifically, the
hook member 32, which is provided on thefirst guide wall 28, allows displacement of thecable 50 along the longitudinal direction, while conversely, thehook member 32 restricts displacement of thecable 50 in a direction whereby thecable 50 would separate away from thecable guide 24, i.e., in the radial direction of thecable 50. - Still further, since it is not necessary to install a plurality of clamp members, as used in the sensor mounting structure of the conventional art, with respect to the
fins 38 of theevaporator 14, damage to thefins 38, which is a problem when such clamp members are installed, can be avoided. - Further, because the
cable 50 of thedetection sensor 46 is firmly retained by thecable guide 24, thecable 50 is not subjected to bending in the vicinity of the side surface of theevaporator 14, and thus thecable 50 coming into contact with the air mixing door (not shown), which would be of concern if thecable 50 were to become bent, can be avoided. - The mounting structure for a sensor, which is attached to a heat exchanger according to the present invention, is not limited to the aforementioned embodiment. It is a matter of course that various changes and modifications may be adopted without departing from the scope and essence of the invention as set forth in the appended claims.
