Description

  The present invention relates to an outdoor unit of a refrigeration apparatus.

  Conventionally, an outdoor unit of a refrigeration apparatus is installed with a base leg fixed below a bottom plate of a casing.

  Here, for example, as in the example described in Patent Document 1 (Japanese Patent Laid-Open No. 2007-147250), a heat exchanger having three or more suction surfaces is provided, and the top view is substantially rectangular. In any of the conventional outdoor units, the base legs provided below the bottom surface of the outdoor unit casing are provided so as to extend along the longitudinal direction of the bottom surface.

  However, in an outdoor unit having a heat exchanger that has three or more suction surfaces to ensure a wide suction surface, the torsional rigidity cannot be sufficiently increased because the side surface that can be covered by the side plate is small. There is a fear.

  Here, there are only the base legs in the conventional outdoor unit that are used by being fixed to the front and rear edges of the bottom plate in a posture extending along the longitudinal direction of the bottom plate. No fixed position has been proposed, and no study has been made from the viewpoint of increasing torsional rigidity.

  The subject of this invention is made | formed in view of the point mentioned above, and it is providing the outdoor unit of the freezing apparatus which can improve torsional rigidity, ensuring the suction surface in a heat exchanger widely.

  The outdoor unit of the refrigeration apparatus according to the first aspect includes a heat exchanger, a casing, and a plurality of base legs. The heat exchanger has at least three air suction surfaces. The casing has a bottom plate, a top plate, and four or more struts. Each column extends from the bottom plate to the top plate. The casing accommodates the heat exchanger therein so that two adjacent air suction surfaces of the heat exchanger are exposed to the outside. The plurality of foundation legs are fixed below the bottom plate. The width in the longitudinal direction of the bottom plate is greater than 1.0 times and less than or equal to 2.8 times the width in the direction orthogonal to the longitudinal direction of the bottom plate. The plurality of base legs extend in a direction orthogonal to the longitudinal direction of the bottom plate.

  In addition, the direction orthogonal to the longitudinal direction of a baseplate is a horizontal direction, for example. The width in the longitudinal direction of the bottom plate means the maximum length in the direction. Moreover, the width | variety of the direction orthogonal to the longitudinal direction of a baseplate means the maximum length in the said direction.

  Since the heat exchanger included in the outdoor unit of the refrigeration apparatus has at least three air suction surfaces, the outdoor unit of the refrigeration apparatus including the heat exchanger having only two or one air suction surface is It has been eliminated.

  Here, a heat exchanger having at least three air suction surfaces is provided, and the heat exchanger is accommodated in the casing so that two adjacent air suction surfaces of the heat exchanger are both exposed to the outside. In the outdoor unit of a refrigeration apparatus having a bottom plate whose width in the longitudinal direction of the bottom plate is greater than 1.0 times and less than or equal to 2.8 times the width in the direction perpendicular to the longitudinal direction of the bottom plate, the bottom plate is fixed below the bottom plate. It is possible to increase the torsional rigidity of the outdoor unit of the refrigeration apparatus by providing the plurality of base legs so as to extend in a direction perpendicular to the longitudinal direction of the bottom plate, rather than extending in the longitudinal direction of the bottom plate. It was confirmed by the test.

  As described above, a plurality of base legs are provided so as to extend in a direction orthogonal to the longitudinal direction of the bottom plate, thereby providing a heat exchanger having at least three air suction surfaces to ensure a wide heat exchange area. However, the torsional rigidity can be increased.

  The outdoor unit of the refrigeration apparatus according to the second aspect is an outdoor unit of the refrigeration apparatus according to the first aspect, and the width in the longitudinal direction of the bottom plate is 1.4 times or more the width in the direction orthogonal to the longitudinal direction of the bottom plate. 2.8 times or less. The base legs are provided near one end and the other end in the longitudinal direction of the bottom plate and between them.

  In the outdoor unit of this refrigeration apparatus, the width in the longitudinal direction of the bottom plate is orthogonal to the longitudinal direction of the bottom plate by using the three base legs disposed near and at one end in the longitudinal direction of the bottom plate. The torsional rigidity can be increased even when the length is relatively longer than the width.

  The outdoor unit of the refrigeration apparatus according to the third aspect is an outdoor unit of the refrigeration apparatus according to the second aspect, and the base leg extends from one end to the other end in a direction orthogonal to the longitudinal direction of the bottom plate. Three times the distance from one end to the other end in the direction perpendicular to the longitudinal direction of the bottom plate is shorter than twice the distance from one end to the other end in the longitudinal direction of the bottom plate.

  In the conventional outdoor unit of the refrigeration apparatus, two base legs are provided so as to extend in the longitudinal direction of the bottom plate in the vicinity of one end and the vicinity of the other end in the direction orthogonal to the longitudinal direction of the bottom plate.

  On the other hand, in the outdoor unit of the refrigeration apparatus, the three units extend from one end to the other end in the direction perpendicular to the longitudinal direction of the bottom plate, in the vicinity of one end and the other end in the longitudinal direction of the bottom plate and in the middle thereof. Is provided. Then, three times the distance from one end to the other end in the direction perpendicular to the longitudinal direction of the bottom plate is shorter than twice the distance from one end to the other end in the longitudinal direction of the bottom plate. Therefore, the total length of the three base legs in the outdoor unit of the refrigeration apparatus (the length in the direction in which the base legs extend) is set so as to extend in the longitudinal direction of the bottom plate as in the prior art. Can be made shorter than the total length of the two base legs (the length in the direction in which the base legs extend).

  As described above, it is possible to increase the torsional rigidity while reducing the material cost by shortening the required length of the foundation leg.

  The outdoor unit of the refrigeration apparatus according to the fourth aspect is the outdoor unit of the refrigeration apparatus according to the first aspect, and the width in the longitudinal direction of the bottom plate is 1.0 times the width in the direction orthogonal to the longitudinal direction of the bottom plate. Larger than 1.4 times. The base legs are provided near one end and the other end in the longitudinal direction of the bottom plate.

  In the outdoor unit of this refrigeration apparatus, when the width in the longitudinal direction of the bottom plate is larger than 1.0 times and smaller than 1.4 times the width in the direction perpendicular to the longitudinal direction of the bottom plate, Two foundation legs in the vicinity of the other end are provided. Thus, when the width in the longitudinal direction of the bottom plate is relatively short compared to the width orthogonal to the longitudinal direction of the bottom plate, the number of foundation legs is not three, but near one end and the other end in the longitudinal direction of the bottom plate. Even if the number is limited to two, sufficient torsional rigidity can be ensured.

  The outdoor unit of the refrigeration apparatus according to the fifth aspect is the outdoor unit of the refrigeration apparatus according to any one of the first to fourth aspects, and the casing is configured to have a substantially rectangular top view. The casing has two side plates. The two side plates extend at a height position corresponding to the heat exchanger. The two side plates are provided at positions adjacent to each other when viewed from above. The heat exchanger has four air suction surfaces provided along the side surface of the casing.

  In the outdoor unit of the refrigeration apparatus, the four air suction surfaces of the heat exchanger are provided, so that even if the heat exchange area is wide, the casing has two side plates and 4 that partially cover the side surfaces. It is possible to increase torsional rigidity by arranging a plurality of base legs so as to extend in a direction orthogonal to the longitudinal direction of the bottom plate while having more than one support column. Thereby, even if it is a case where the heat exchange area is ensured widely, it becomes possible to improve torsional rigidity.

  In the outdoor unit of the refrigeration apparatus according to the first aspect, it is possible to increase torsional rigidity even when a large heat exchange area is secured by providing a heat exchanger having at least three air suction surfaces. ing.

  In the outdoor unit of the refrigeration apparatus according to the second aspect, the torsional rigidity can be increased even when the width of the bottom plate in the longitudinal direction is relatively long.
