A radiator (heat exchanger) 14 for cooling the cooling water and a filter 16 provided substantially in parallel with the condenser 12 are included.

  In addition, when the heat exchanger unit 10 is mounted in the engine room of the vehicle, the condenser 12 is disposed on the vehicle front side (arrow A1 direction) and the radiator 14 is on the vehicle rear side (arrow A2 direction). .

  The capacitor 12 includes, for example, a pair of first and second tanks 18 and 20 extending in the vertical direction (arrow B1 and B2 directions), and between the first tank 18 and the second tank 20. A plurality of tubes 22 to be connected and a plurality of fins 24 provided between the tubes 22 and bent in a wave shape are included. In addition, the capacitor | condenser 12 comprises the heat exchange part 26 from the tube 22 and the fin 24, and performs heat exchange with the air and refrigerant | coolant which pass.

  The capacitor 12 is used so that the tube 22 is substantially horizontal and the first and second tanks 18 and 20 are disposed at both ends in the horizontal direction, and the fins 24 are two tubes 22 adjacent in the height direction. Between.

  The first and second tanks 18 and 20 are formed in, for example, tubular shapes whose both ends are closed, and holding means for holding the filter 16 at a position on the vehicle front side of the capacitor 12 (arrow A1 direction). 28 is provided.

  The holding means 28 is provided, for example, in pairs along the longitudinal direction (arrow B1, B2 direction) of the first and second tanks 18 and 20, spaced apart from each other by a predetermined distance, and the first and second tanks 18 and 20 are provided. A pair of first holders 30a and 30b provided in the vicinity of the upper ends of the first and second tanks 18 and 20 and a pair of second holders 32a and 32b provided in the vicinity of the lower ends of the first and second tanks 18 and 20.

  The first holders 30a and 30b and the second holders 32a and 32b are formed in substantially the same shape, and are bent at a substantially right angle after being separated from the outer peripheral surfaces of the first and second tanks 18 and 20 by a predetermined height. The guide portions 34 respectively extend toward the inner side in the width direction of the capacitor 12 (see FIG. 3).

  That is, as shown in FIG. 3, the first holders 30 a and 30 b and the second holders 32 a and 32 b are formed in an L-shaped cross section when viewed from the extending direction of the first and second tanks 18 and 20. The part 34 is provided substantially parallel to the heat exchange part 26 including the tube 22.

  The second holders 32a and 32b have locking portions 36 (see FIG. 2) that are substantially orthogonal to the guide portions 34 and extend in the horizontal direction at the lower ends thereof, and the inside of the second holders 32a and 32b. The end of the filter 16 inserted through is locked and held.

  The holding means 28 is not limited to the case where the first holders 30a and 30b and the second holders 32a and 32b are separately provided as described above. The first holder and the second holder may be integrally formed along the tank 20.

  The radiator 14 is provided on the back side of the capacitor 12 on the rear side of the vehicle (in the direction of the arrow A2), and is provided substantially parallel to the capacitor 12 with a predetermined interval. The radiator 14 includes, for example, a pair of third and fourth tanks 38 and 40 extending in the vertical direction (directions of arrows B1 and B2), and a space between the third tank 38 and the fourth tank 40. A plurality of tubes 42 to be connected, and a plurality of fins 44 provided between the tubes 42 and bent in a wave shape, and cooling water supplied from an engine (not shown) to the third tank 38 is a plurality of tubes 42. Is circulated from the fourth tank 40 to the third tank 38 and then supplied to the engine.

  In the radiator 14, the third and fourth tanks 38 and 40 are connected to the first and second tanks 18 and 20 of the capacitor 12.

  The filter 16 includes, for example, a filter portion 46 through which air can pass, and a frame 48 provided so as to surround the filter portion 46. The filter portion 46 includes fibers formed in a mesh shape, It is formed from a non-woven fabric bent in a plurality of wave shapes and is held in a frame 48 formed in a substantially rectangular shape. The filter unit 46 is preferably made of a water-resistant material in consideration of moisture adhesion because rain or the like is applied when the vehicle travels.

  Further, the filter 16 is formed such that its width dimension and height dimension are slightly smaller than the width dimension and height dimension of the capacitor 12, and as shown in FIG. 12 is inserted between the surface of the capacitor 12 and the holding means 28 from above (see the two-dot chain line shape in FIG. 2), and is guided by the guide portions 34 of the first holders 30a and 30b and the second holders 32a and 32b. However, by moving downward (in the direction of arrow B2 in FIG. 1), the capacitor 12 is held in parallel with a predetermined distance from the surface of the capacitor 12, and its lower end is a locking portion 36. Held by.

  Further, by forming the thickness of the filter 16 to be thinner than the thickness of the capacitor 12 along the vehicle front-rear direction (arrow A1, A2 direction), for example, an increase in ventilation resistance is suppressed.

  The heat exchanger unit 10 according to the embodiment of the present invention is basically configured as described above. Next, the operation and effects thereof will be described.

  First, in the capacitor 12 with the filter 16 attached to the front side of the vehicle (in the direction of the arrow A1), the refrigerant is supplied from a pipe (not shown) through the introduction port into the first tank 18 and through the plurality of tubes 22 to the second tank 20 side. Then, after flowing again to the first tank 18 side, it is led out from the outlet port to a pipe (not shown).

  When the vehicle travels, the traveling wind F passes through the filter portion 46 of the filter 16 from the front of the vehicle, then flows through the heat exchanging portion 26 of the condenser 12 and flows to the vehicle rear side (arrow A2 direction). In the filter unit 46, pollutants and dust in the air are preferably captured, and the purified air flows to the downstream side, and also passes through the refrigerant and the fins 24 flowing through the tubes 22 in the heat exchange unit 26. Heat exchange is performed with the air to be cooled, and the cooled refrigerant circulates to a compressor (not shown).

  As described above, in the present embodiment, when the heat exchanger unit 10 is mounted in the engine room of the vehicle, the filter 16 is provided on the surface side of the condenser 12 that is the front side of the vehicle (in the direction of the arrow A1) and held. It is held by means 28.

  Accordingly, when the vehicle travels, air passes through the filter portion 46 of the filter 16 as the traveling wind F, so that contaminants and dust in the air are preferably captured and removed, so that the air flowing downstream is purified. As a result, air pollution can be reduced. Further, even when a stepping stone or the like flying from the road hits the heat exchanger unit 10 during traveling, the capacitor 12 is prevented from being damaged by hitting the filter 16 on the vehicle front side (arrow A1 direction). Therefore, durability can be improved.

  That is, the filter 16 functions as a protection means for protecting the capacitor 12 from a stepping stone or the like during traveling, and at the same time has a purification function for purifying air passing during traveling.

  In other words, a vehicle equipped with the heat exchanger unit 10 including the filter 16 can purify the atmosphere as it travels with the filter 16, and thus contributes to reducing air pollution simply by traveling. It becomes possible.

  Further, since the filter 16 can be easily mounted by inserting it into the holding means 28 from above the capacitor 12, maintenance such as replacement work is easy.

  Furthermore, since the durability of the tube 22 and the fin 24 in the capacitor 12 is improved by providing the filter 16, it is necessary to set the strength in consideration of contact with a stepping stone or the like when designing the tube 22 and the fin 24. Therefore, the tubes 22 and the fins 24 can be thinned, and the weight can be reduced accordingly.

  Furthermore, the filter 16 is combined with a planar structure in the same manner as the capacitor 12 provided on the rear side of the vehicle (in the direction of the arrow A2), so that the traveling wind F can be applied in the direction (in the directions of the arrows A1 and A2). Since the rigidity can be increased, deformation when the traveling wind F hits can be prevented.

  Further, the holding means 28 described above is not limited to the case where the first holders 30a and 30b and the second holders 32a and 32b are configured. For example, the holding means 28 has a cross section like the holding means 100 shown in FIG. 4A. Instead of the L-shaped holder, a pair of second holders 102 a and 102 b having pins 104 may be used.

  As shown in FIG. 4B, the second holders 102 a and 102 b have a base portion 106 formed in an arc shape in cross section, and are formed so that the pins 104 protrude from the outer peripheral surface of the base portion 106. .

  The second holders 102a and 102b are fixed to the outer peripheral surfaces of the first and second tanks 18 and 20 having a circular cross section by welding or the like, so that the pins 104 are connected to the first and second tanks 18 and 18. It will be in the state which protruded in the orthogonal direction with 20 axes.

  When the filter 16 is fixed to the capacitor 12, as shown in FIG. 4A, for example, after the upper part of the filter 16 is inserted into the first holders 30a and 30b from the lower side, the lower part of the filter 16 is inserted. Is inclined so as to be separated from the capacitor 12, and the lower portion is inclined toward the capacitor 12 side while aligning the positions of the hole portion 108 formed in the frame 48 of the filter 16 and the pin 104.

  Finally, by inserting the pin 104 into the hole 108 of the filter 16, the movement of the filter 16 in the vertical downward direction (arrow B2 direction) is restricted by the second holders 102a and 102b, and the filter 16 The movement in the direction away from the capacitor 12 becomes a holding state regulated by the first holders 30a and 30b and the second holders 102a and 102b.

  Furthermore, as shown in FIG. 5, the filter 16 may be disposed between the back surface of the capacitor 12 and the surface of the radiator 14 and held by holding means 110 (not shown) provided on the radiator 14. As a result, the traveling wind F that has passed through the condenser 12 during traveling of the vehicle passes through the filter portion 46 of the filter 16, so that contaminants and dust in the air can be captured and the air can be purified. As in the case where the filter 16 is provided (in the direction of the arrow A1), it is possible to reduce air pollution. The filter 16 is not limited to the case where it is provided on either the vehicle front side (in the direction of arrow A1) relative to the capacitor 12 or the vehicle rear side (in the direction of arrow A2) of the capacitor 12 as described above. Instead, they may be provided on the front and back sides of the capacitor 12, respectively. As a result, it is possible to enhance the ability to remove contaminants in the atmosphere.

  The heat exchanger unit according to the present invention is not limited to the above-described embodiment, and can of course have various configurations without departing from the gist of the present invention.
