  However, in conventional outdoor-mounted radiator devices, snow and rainwater fall in four directions, so rust and dirt generated in ducts and radiator storage cases due to snow and rainwater are visible to the public, and wooden buildings etc. are around the radiator device. In some cases, a wooden building or the like may be corroded by snow or rainwater falling from the roof member. Therefore, when installing a radiator apparatus outdoors, there existed a problem that the place which can be installed was restricted.

  In addition, when snow falls in the direction in which people are present, there is a risk that accidents such as injuries may occur due to the falling snow.

  An object of the present invention is to provide an outdoor installation type radiator apparatus that can be installed in many places and can prevent accidents caused by snowfall.

  The outdoor installation type radiator device of the present invention includes a radiator, a radiator storage case in which the radiator is stored, a duct, a roof member, and an induction fan. The duct is disposed on the radiator storage case so that the internal space of the radiator storage case communicates with the ventilation path. The roof member is attached to the duct via attachment means, and is disposed so as to be spaced apart from the exhaust port of the duct and is opposed to the exhaust port. The induction blower is disposed in the radiator storage case and / or the duct, draws air from inside the radiator storage case so that the cooling air passes through the radiator, and discharges the air through the duct. The duct includes a first duct structure fixed to the radiator storage case, and a second duct structure located on the first duct structure and connected to the first duct structure via the connection structure. Body. The coupling structure rotates the second duct structure in the circumferential direction around a virtual center line extending in the vertical direction through the center of the first duct structure, and thereby the second duct with respect to the first duct structure. The mounting position of the structure is allowed to be changed. The shape of the roof of the roof member is either a gable roof, a single-flow roof, or a vault roof. Here, the gable roof is a roof having two inclined surfaces so as to form a ridge. A single-flow roof is a roof composed of one inclined surface. The vault roof is a roof having a curved surface so that the cross section is a semicircular arc or a fan shape.

  In the present invention, the connection structure that connects the first duct structure and the second duct structure is circumferentially centered on a virtual center line that extends vertically through the center of the first duct structure. The second duct structure is rotated to allow changing the mounting position of the second duct structure relative to the first duct structure. And the shape of the roof of a roof member is either a gable roof, a single flow roof, or a vault roof. For this reason, when the roof shape of the roof member is a gable roof or a vault roof, the direction in which snow or rainwater collected above the roof member falls is 180 degrees different from each other, and the roof shape of the roof member is a single-flow roof. In this case, the direction in which the snow and rain water accumulated above the roof member falls is one direction. And the direction in which snow and rainwater fall can be changed suitably by changing the attachment position of the 2nd duct structure with respect to the 1st duct structure. For this reason, by setting the direction in which snow and rainwater fall to a direction in which people do not enter, it is possible to prevent the rust and dirt of the duct and the radiator storage case from being noticed. In addition, when there is a wooden building or the like around the radiator device, it is possible to prevent snow or rainwater from falling in a certain direction of the wooden building or the like. Therefore, the place where a radiator apparatus can be installed can be increased.

  In addition, by determining the direction in which snow falls so as to avoid the direction in which people are present, accidents due to snowfall can be prevented.

  The connection structure includes a flange portion provided at the upper end portion of the first duct structure so as to surround the ventilation path, an opposing wall portion provided in the second duct structure and facing the flange portion, and a virtual center line. A plurality of first through holes formed in the flange portion at equal intervals in the circumferential direction along an imaginary circle centered at the center and a plurality of first through holes provided in the opposing wall portion and penetrating the opposing wall portion. A plurality of second through holes aligned with the one through hole, a plurality of bolts passing through the aligned first through holes and the plurality of second through holes, and a plurality of bolts, respectively. And a plurality of nuts. In this case, an appropriate mounting position of the second duct structure with respect to the first duct structure is determined, and a plurality of bolts are attached to the plurality of first through holes and the plurality of second through holes at the position. The first duct structure body and the second duct structure body are connected to each other by screwing a plurality of nuts into a plurality of bolts. In this way, a plurality of first through holes are formed in the flange portion of the first duct structure, and a plurality of second through holes are formed in the opposing wall portion of the second duct structure. Thus, a connection structure that can easily change the mounting position of the second duct structure relative to the first duct structure can be configured. Moreover, the number of attachment positions of the second duct structure relative to the first duct structure can be changed by adjusting the number of the plurality of first and second through holes.

  The plurality of nuts can be fixed to either the flange portion or the opposing wall portion. If it does in this way, a volt | bolt and a nut can be firmly attached to a flange part and an opposing wall part.

  A 2nd duct structure can be comprised so that it may have an opposing wall part and the surrounding wall part which stands up from the outer-periphery edge part of an opposing wall part, and extends upwards. In this case, it is preferable that lower end portions of a plurality of support pillars as attachment means are attached to the upper end portion of the peripheral wall portion with a predetermined interval, and a roof member is attached to the upper end portions of the plurality of support posts. . If it does in this way, the space | interval of sufficient magnitude | size can be opened between the exhaust port of a duct, and a roof member by several support | pillars, and the flow of cooling air becomes smooth.

  When the contour shape of the outer peripheral part of the opposing wall part is rectangular, and the peripheral wall part is a rectangular square tube, the lower end of the four columns at the four corners of the upper end of the peripheral wall The roof shape of the roof member is such that the upper edge is positioned along one side of the upper end portion of the peripheral wall portion, and the lower edge is positioned along the other side facing the one side of the upper end portion. A single-flow roof is preferred. If it does in this way, a roof member can be firmly attached to a duct by four support | pillars. Moreover, a roof member can be easily formed by making a roof member into a single flow roof. Furthermore, since the snow and rainwater accumulated above the roof member fall in only one direction, the number of places where the radiator device can be installed can be increased.

  It is preferable that a window, a punching plate or a fence having a plurality of through holes formed therein is disposed in a window formed between two adjacent columns. If it does in this way, it can prevent that an object falls accidentally from a window part in a duct or a radiator.

  The upper edge portion of the first duct structure and the lower edge portion of the second duct structure can be configured to be fitable. In this case, the connection structure has a plurality of first through holes formed at equal intervals in the circumferential direction along a virtual circle centered on the virtual center line at the upper edge of the first duct structure, A plurality of second through holes provided at a lower edge portion of the second duct structure and aligned with the plurality of first through holes; a plurality of first through holes; and a plurality of second through holes. It can be comprised from the some volt | bolt which penetrates, and the some nut screwed together by the some volt | bolt, respectively. If it does in this way, the shape of the 1st duct structure and the 2nd duct structure can be simplified, and a connection structure can be constituted.

  The first duct structure has a cylindrical shape, and the impeller of the induction blower rotates inside the first duct structure, so that the motor of the induction blower is located in the second duct structure. It is preferable to attach the induction blower to the first duct structure. If it does in this way, the 2nd duct structure can be easily removed from the 1st duct structure. In addition, by removing the second duct structure from the first duct structure, the induction fan can be easily repaired. Moreover, since the impeller of the induction blower rotates inside the cylindrical first duct structure, the cooling air can flow smoothly and wind noise can be reduced.

  According to the present invention, the connection structure that connects the first duct structure and the second duct structure is formed around the virtual center line that extends in the vertical direction through the center of the first duct structure. The second duct structure is rotated in the direction to change the mounting position of the second duct structure relative to the first duct structure. And the shape of the roof of a roof member is either a gable roof, a single flow roof, or a vault roof. For this reason, when the roof shape of the roof member is a gable roof or a vault roof, the direction in which snow or rainwater collected above the roof member falls is 180 degrees different from each other, and the roof shape of the roof member is a single-flow roof. In this case, the direction in which the snow and rain water accumulated above the roof member falls is one direction. And the direction in which snow and rainwater fall can be changed suitably by changing the attachment position of the 2nd duct structure with respect to the 1st duct structure. For this reason, by setting the direction in which snow and rainwater fall to a direction in which people do not enter, it is possible to prevent the rust and dirt of the duct and the radiator storage case from being noticed. In addition, when there is a wooden building or the like around the radiator device, it is possible to prevent snow or rainwater from falling in a certain direction of the wooden building or the like. Therefore, the place where a radiator apparatus can be installed can be increased.

  In addition, by determining the direction in which snow falls so as to avoid the direction in which people are present, accidents due to snowfall can be prevented.

An induction fan 9 is attached to the first duct structure 23. As shown in FIG. 3, the induction blower 9 includes a motor 29, an attachment member 31 that is fixed to the motor 29 and attaches the motor 29 to the first duct structure 23, and an impeller 33 that is rotated by the motor 29. is doing. The attachment member 31 has a plate shape, and a part thereof is attached to the inner wall surface of the first duct structure 23 by welding. The motor 29 is fixed to the mounting member 31 so as to be located in the second duct structure 25. The impeller 33 is attached to the motor 29 so as to rotate inside the first duct structure 23. The impeller 33 attracts air from inside the radiator storage case 3 so that the cooling air passes through the radiator 1 and discharges it through the duct 5.

  The second duct structure 25 has an opposing wall portion 35 that opposes the flange portion 27 of the first duct structure 23, and a rectangular prismatic shape that rises upward from the outer peripheral edge of the opposing wall portion 35. And a peripheral wall portion 37. The contour shape of the outer peripheral portion of the facing wall portion 35 is rectangular and has a circular opening 39 in the center. As shown in FIG. 5, the opposing wall 35 is formed with 16 second through holes 35a that penetrate the opposing wall 35 and align with the 16 first through holes 27a.

  Here, a connection structure between the first duct structure 23 and the second duct structure 25 will be described.
