Description

  The present invention relates to an auxiliary cooling device that cools an air blown to a condenser of an outdoor unit used for an air conditioner / refrigerator / refrigerator, etc. by passing it through a cooling mat in which water flows in advance. It is related with the auxiliary | assistant cooling device provided with the pressing member which presses down the inner side part surrounded by the said peripheral part of the cooling mat in which is held.

  Conventionally, in a refrigeration cycle such as an air conditioner / refrigerator / refrigerator, the outdoor unit becomes high temperature due to heat generated when the refrigerant is liquefied by the condenser, so the condenser needs to be cooled. For example, an air-cooled mechanism that cools the condenser by exchanging heat with air flowing in contact with the radiating fins provided in the condenser is inexpensive because the device structure is simple, but outdoor air in summer When the temperature is high, there is a problem that the cooling efficiency inside the room and the room is lowered. Therefore, many proposals have been made to use an auxiliary cooling device for an air-cooled condenser, and a typical example of such a device is to spray finely granular or mist-shaped water from the spray nozzle directly on the heat radiation fins. In addition, an auxiliary cooling device is known in which the radiation fins are cooled by the latent heat of vaporization of the sprayed water to improve the cooling efficiency of the refrigeration cycle. This type of auxiliary cooling device is operated as a conventional air cooling device at times other than summer, and scales and scales adhere to the surface of the radiating fins while the operation is continued for a long period of time. It is inevitable that the exchange efficiency will be reduced and the fins will be corroded.

  As an example of an auxiliary cooling device used for an air-cooled condenser, the present applicant has already arranged a cooling mat in the vicinity of the heat dissipating fins of the condenser, and caused cooling water to flow down to the cooling mat so that the intake air of the condenser is reduced. A method of cooling is proposed (see Patent Document 1). This type of auxiliary cooling device does not spray cooling water directly onto the radiator fins, but indirectly cools the condenser by cooling the air flowing toward the condenser fins with cooling water. Therefore, the cooling fins do not corrode the heat radiation fins or adhere to the scale. Further, since this auxiliary cooling device can be added to a conventional condenser, it can be attached to an existing unit, and can be easily attached / detached and cleaned. Moreover, since the cooling mat can also utilize a waste material, it has the advantage that it also becomes effective use of resources.

  FIG. 9 is a view showing an example of an outdoor unit 1 to which a conventional auxiliary cooling device is applied, and FIG. 10 is a schematic view schematically showing an example of a device using a conventional refrigeration cycle. In the refrigeration cycle 10 shown in FIG. 10, a compressor 11, a condenser 2, a dryer 14, an expansion valve 13, and an evaporator 12 are connected by a refrigerant pipe 7 so as to constitute a refrigeration cycle. An auxiliary cooling device 20 is provided in the vicinity of a condenser constituting a conventionally known refrigeration cycle (not shown), that is, at a position away from the cooling fan 3 attached to the condenser 2 by a certain distance. The auxiliary cooling device 20 includes a water supply pipe 31 communicating with the water pipe in order to sprinkle the cooling water on the mat-shaped cooling mat 21 and a water supply unit 30 for supplying the water supply pipe 31 with the cooling water. The water supply unit 30 is interposed in the water supply pipe 31 and serves as an open / close valve for shutting off or passing the tap water, a thermostat 33 for controlling the opening / closing of the electromagnetic valve 32, and an auxiliary for operating the thermostat 33. A sensor 34 for measuring the temperature of the air flowing into the cooling device 20 is provided.

  In the auxiliary cooling device applied to the above-described refrigeration cycle, when the sensor 34 senses that the temperature of the inflowing air is equal to or higher than a set value, the thermostat 33 operates to open and close the electromagnetic valve 32. When the electromagnetic valve 32 is opened, tap water is supplied to the cooling mat 21 from the watering means (not shown) through the water supply pipe 31. The water that has flowed down the cooling mat 21 is stored in the water storage tank 25 for reuse, and circulates while cooling the air flowing into the condenser 2. As the cooling water supplied to the auxiliary cooling device, drain water generated in the evaporator 12 may be used instead of part or all of the tap water.

  The cooling mat 21 is evaporated by the air flow sucked from the side when the cooling water falls through the gap inside. At that time, the air flow is deprived of the heat of evaporation and cooled, and air containing a large amount of moisture is supplied to the heat exchange unit. As the properties of the material of the cooling mat 21, it is preferable that the resistance at the time of air passage is small, heat exchange with the falling cooling water is smooth, and durable. As the mat through which air easily passes, it is preferable to use, for example, a non-woven fibrous body, for example, a material obtained by recycling waste plastic into a fibrous form from the viewpoint of effective use of resources. The shape of the cooling mat 21 is preferably a shape that substantially covers the air suction surface of the condenser 2, and the thickness may be about several centimeters depending on the material and shape. In addition, the cooling mat 21 can have flexibility in installation by selecting a stretchable material. Furthermore, as long as the cooling mat 21 is a material in which cooling water is transferred to the outside of the fibrous material, the cooling mat 21 may employ other forms such as a synthetic resin body having open cells.

  In the auxiliary cooling device shown in FIG. 9 and the outdoor unit 1 to which the auxiliary cooling device is applied, the description overlapping the description of the refrigeration system shown in FIG. 10 is omitted. The auxiliary cooling device 20 includes a cooling mat 21 corresponding to the size of the outdoor unit 1 and the like, and a support frame that supports the cooling mat 21, and a water sprinkler 22 ( (Or water spray pipe). The auxiliary cooling device 20 is attached to the outdoor unit 1 by a support portion 27 that is a metal fitting. The water sprinkle 22 that is a means for supplying water to the cooling mat 21 sprays the cooling water supplied from the water supply pipe 31 of the water supply unit 30 evenly on the upper portion of the cooling mat 21. A large number of water holes are formed in the bottom of the water sprinkle 22, and the cooling water is formed to drop substantially uniformly from the water holes. The cooling water cools the air passing toward the condenser 2 while flowing in the cooling mat 21 from the water sprinkler 22 of the auxiliary cooling device 20 and flowing down. Although the water sprinkler 22 as the water supply means is disposed above the cooling mat 21, the entire structure can be simplified by disposing the water sprinkling pipe in the cooling mat 21.

  The cooling water that has cooled the air sucked into the condenser 2 is dropped from the lower portion of the cooling mat 21 and received by the drainage basin 23 and collected. In the example shown in FIG. 9, the drainage means includes a drainage basin 23 and drains directly to the ground or floor through a drainage pipe 28 connected to one end thereof, but as shown in FIG. Obviously, it may be collected in the tank 25. The water sprinkler 22 and the drain spit 23 may be a sprinkler pipe and a drain pipe, respectively.

  In the indirect auxiliary cooling device 20 that uses the cooling mat 21 to contain a large amount of moisture in the air, the cooling mat 21 is arranged at a certain distance from the radiation fins, so that the cooling water is supplied to the radiation fins. Influence (corrosion, scale adhesion, etc.) can be reliably prevented. The refrigeration cycle 10 shown in FIG. 10 has been described with one condenser 2 arranged, but as shown in FIG. 9, two condensers are arranged on both sides of the apparatus main body, and the auxiliary cooling devices 20 and 20a are also provided. It can also be provided symmetrically by providing it on both air inflow sides of each outdoor unit 1. Moreover, the combination of the outdoor unit 1 and the auxiliary cooling device 20 may be one set, and a plurality of sets may be arranged in parallel.

  In general, the size of the condenser of the outdoor unit or the apparatus main body of the auxiliary cooling device 20 differs depending on the model. In this case, a support frame is configured according to the size of the apparatus main body, It is required to be used in combination. In addition, every time the model of the outdoor unit is changed, the support frame that provides the cooling device mat is designed according to the size and specifications of the device, such as the width of the device. There is a problem that the design change of the support frame that holds the frame must be performed. In view of this, the present applicant has already proposed an auxiliary cooling device configured such that the length of the support frame can be adjusted according to the size of the outdoor unit (Japanese Patent Application No. 2005-135749).

In the conventional auxiliary cooling device 20, the cooling mat is a fiber-like thin cloth-like article that is easily bent and is supported by the support frame at the periphery thereof. Therefore, there is a problem that a curved deformation tends to occur on the back side, that is, on the outdoor unit side. In order to prevent such bending deformation, as shown in FIG. 7, the wire 90 stretched diagonally on the support frame is used as a presser for holding the cooling mat, particularly on the side that becomes the outdoor unit side when installed. As shown in FIG. 8, pressers 95 and 95 for holding the cooling mat in the form of a bar extending in the vertical direction at a predetermined location are also used on the side that becomes the outdoor unit side when mounted. When exposed to a storm such as a typhoon or a strong wind, there is a problem that the front side is likely to bend and deform, and it has also been proposed to hold the front side deformation with a spring clip. Most of the sprayed water for cooling flows in the cooling mat, but some of the water is scattered from the cooling mat. There is a problem in that it is more easily scattered to the outside, is not spent for cooling, and waste water is generated.
JP 2004-3806 (paragraphs [0014] to [0023], FIGS. 1 to 3)

  Therefore, in the auxiliary cooling device used in combination with the main unit of the outdoor unit of the refrigeration system, there is a problem to be solved in that it prevents curved deformation on either the front or back side of the cooling mat and collects water scattered from the cooling mat. is there.

  An object of the present invention is to provide an auxiliary cooling device that supports a cooling mat with a support frame and is used in combination with a main body of an outdoor unit of a heat exchange device, and prevents bending deformation on both the front and back sides of the cooling mat and cooling. It is an object of the present invention to provide an auxiliary cooling device that makes it possible to collect water scattered from a mat and avoid the generation of waste water.

  In order to solve the above problems, an auxiliary cooling device according to the present invention includes a support frame and a cooling mat supported by the support frame and capable of flowing water, and is supplied to a heat radiating unit provided in an outdoor unit of the heat exchange device. The auxiliary cooling device cools the air by passing the air passing through the cooling mat, and the support frame extends laterally on each of the front and back sides of the cooling mat and restricts deformation of the cooling mat. One or a plurality of pressing members are attached.

  According to this auxiliary cooling device, the support frame is provided with one or more laterally extending pressing members on the front and back sides of the cooling mat to restrict the bending deformation of the cooling mat. Depending on the installation environment of the apparatus, the cooling mat can be prevented from being bent and deformed due to a strong wind. The cooling mat cools the passing air with the evaporation heat of water and supplies it to the outdoor unit. Therefore, the cooling mat is generally manufactured in a thin mat shape and is easily affected by wind and suction air flow. Thus, the deformation of the cooling mat from the flat shape originally present in the support frame to the in-plane outside of the support frame is restricted. In addition, the regulation of the cooling mat by the holding member prevents the cooling water flowing through the bent cooling mat from dropping into the floor directly without flowing down the cooling mat. The

In the auxiliary cooling device, the pressing member is Ru Tei with an upper rib portion extending elongated plate-like body extends parallel to the installation surface of the cooling mat, and the upper edge of the elongated plate-shaped body in the outer direction of the cooling mat. If the presser member is composed only of an elongated plate-like main body that extends parallel to the installation surface of the cooling mat, the direction in which the bending rigidity of the plate is weak becomes the same as the bending direction of the cooling mat, and the bending restraining action of the cooling mat as the pressing member Is not sufficiently obtained. Therefore, by providing the upper rib portion extending outward from the upper edge of the elongated plate-like main body, the bending rigidity of the presser member in the same direction as the bending direction of the cooling mat is drastically improved when the presser member is attached to the support frame. Can be increased. Since the upper rib portion extends outward from the cooling mat, the cooling water does not prevent the cooling water from flowing down the upper part of the holding member of the cooling mat.

In the auxiliary cooling device of the above SL, upper rib portion Ru receiving and recoverable der water scattered from cooling mat extend obliquely upward. Since the upper rib part extends diagonally upward, it receives water splashed from the cooling mat, and the received water flows down on the inclined surface of the upper rib part so that it can be automatically collected on the cooling mat. it can.

  In this auxiliary cooling device, it is preferable that the pressing members are disposed to face each other with the cooling mat sandwiched between the front and back surfaces. By arranging the presser member in this way, the cooling mat is regulated on the front and back at the same height position, and the effect of regulating the bending deformation can be exhibited most effectively.

  In the above-described auxiliary cooling device in which the pressing member is opposed to the front and back, the pressing member can include a lower rib portion extending inward of the cooling mat from the lower edge of the elongated plate-like main body. The lower rib portion extending inwardly from the lower edge of the elongated plate-shaped main body has the effect of increasing the bending rigidity of the presser member in the same manner as the upper rib portion. When provided together with the upper rib portion, the bending rigidity of the presser member is further increased. Can be increased. Further, since the lower rib portion positively sandwiches the cooling mat in cooperation with the lower rib portion of the pressing member that enters and opposes the cooling mat, deformation of the cooling mat can be further suppressed. Since a gap in which the cooling mat extends is provided between the opposed lower rib portions, there is no problem in the flow of cooling water.

  In the above-described auxiliary cooling device in which the pressing members are opposed to each other on the front and back sides, both the pressing members that are arranged to face each other can be engaged with each other by an engaging tool. By engaging the presser members disposed opposite to each other, the connection rigidity of the presser members disposed opposite to each other is further enhanced. Moreover, since the distance between both pressing members is restrained by the engaging tool, the effect of restricting the deformation of the cooling mat is further enhanced.

  In the auxiliary cooling device including the engagement tool, the cooling mat is divided in the left-right direction, and the engagement tool can be disposed at the boundary between the adjacent cooling mats. By disposing the engaging tool on the adjacent boundary of the cooling mat divided in the left-right direction, the engagement / disengagement work of the engaging tool to the presser member does not need to be performed through the inside of the cooling mat, and is simplified. be able to.

  In the above auxiliary cooling device, the presser member is composed of a first presser member and a second presser member that are divided into left and right parts and are connected to each other so that the overlapping length can be changed, and correspond to the left and right sizes of the support frame. The overall length can be made variable. The left and right size of the auxiliary cooling device can vary depending on the model, scale, structure, etc. of the outdoor unit, and accordingly, the support frame with different left and right sizes is prepared, or the support frame has a left and right length. A structure that makes the variable is adopted. The left and right sizes of the support frame can also be changed by dividing the first presser member and the second presser member into left and right parts and making the overall length variable by connecting the overlapping lengths of both members in a changeable manner. It can respond to the change of.

Since the auxiliary cooling device according to the present invention is configured as described above, when the cooling mat is supported by the support frame and used in combination with the main body of the outdoor unit of the heat exchange device, one or a plurality of pressers are used. member can be prevented even bending deformation to the front and back either side of the cooling mat, when the cooling mat is resiliently deformed into a curved shape, a waste water water for cooling flowing down is scattered from cooling mat Can be prevented beforehand. Each presser member includes an elongated plate-like main body extending in parallel with the installation surface of the cooling mat and an upper rib portion extending outward from the cooling mat from the upper edge of the elongated plate-like main body . by increasing the bending stiffness, Ru can be maintained, exhibit the function of the pressing member. Furthermore, since the upper rib portion extends obliquely upward, it is possible to provide a recovery function for receiving water and returning it to the cooling mat even when cooling water splashes from the cooling mat portion above the upper rib portion. It is possible to eliminate waste water and reduce the operation cost. Furthermore, when each pressing member has a lower rib portion extending inward from the lower edge of the elongated plate-shaped body, there is an effect of increasing the bending rigidity of the pressing member in the same manner as the upper rib portion. The bending rigidity of the pressing member can be further increased.

  Hereinafter, embodiments of an auxiliary cooling device according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a view showing an example of an auxiliary cooling device according to the present invention, in which (a) is a front view and (b) is a side view. FIG. 2 is a rear view of the auxiliary cooling device shown in FIG. 1 and 2, components that are substantially the same as the components of the auxiliary cooling device described in FIGS. 9 and 10 are denoted by the same reference numerals, and the description thereof is omitted.

  The auxiliary cooling device 40 according to the present invention shown in FIGS. 1 and 2 includes a rectangular cooling mat 21 and a support frame 51 for supporting the mat 21. The support frame 51 includes horizontal frame portions 60 and 60a arranged vertically and vertical frame portions 52 and 52a connected at both ends thereof, and is a horizontally long frame that can accommodate the mat 21 as a whole. It is formed as. A water supply joint 37 and a drainage joint 38 are provided at upper and lower ends of one vertical frame portion 52 of the support frame 51, and are connected to the water supply pipe 31 and the drainage pipe 28, respectively. The cooling mat 21 mounted inside the frame of the auxiliary cooling device 20 is a mat member that is formed by overlapping non-woven fabrics and fibers having a predetermined thickness as in the conventional example, and allows air to pass therethrough. .

  The cooling mat 21 includes wide cooling mats 21a and 21a arranged on the left and right outer sides and cooling mats 21b and 21b having a slightly narrower width near the center. ing. In this example, two mats of two kinds of widths 21a and 21b are combined, but various width sizes of the support frame 51 can be accommodated by adopting other combinations.

  In the auxiliary cooling device 40, in order to define the interval between the auxiliary cooling device 40 and the outdoor unit 1, square pipes as spacers 50 are interposed at the four corners so as to be attached to the outdoor unit 1. As a result, even when dust or dirt adheres to the cooling mat 21 or gets clogged between the fibers, it flows from the gap formed by the spacer 50 between the auxiliary cooling device 20 and the outdoor unit 1. Therefore, it is possible to prevent the cooling capacity from being lowered by securing the cooling air. The square pipe 50 may be a commercially available product, and an appropriate size can be selected and used. By using the side surface of the square pipe 50, the auxiliary cooling device 20 can be stably attached to the outdoor unit 1.

  In the auxiliary cooling device 40, the support frame 51 is a horizontal frame portion 60 that is configured so that the upper and lower portions thereof can be changed in length. The horizontal frame portion 60 is a slidably combined middle frame member 61 having a long central portion as a first frame member and end frame members 70 and 70a having short lengths as second frame members on both sides thereof. Each overlapping portion is fixed with a fixing tool such as a screw so as to have a desired length. The end frame members 70 and 70 a to be combined with the middle frame member 61 are members formed to be slidable along the inner surfaces of the pair of side plate parts 63 and 64 of the middle frame member 61. If there are two fixing points using screws, the fixing can be ensured without wobbling. In the upper space 73, a watering pipe that is a means for supplying water to the cooling mat is used. The structure of the horizontal frame portion 60 is also applied to the lower horizontal frame 60a. In the case of the horizontal frame 60, water supply means such as a sprinkling pipe is accommodated inside, but in the case of the horizontal frame 60a, the internal space is used for the arrangement of the drainage basin or the internal space itself is used as the drainage guide means. Although the structure is different in that it can be performed, the same structure as that of the horizontal frame 60 can be applied to the structure whose length is changed, and thus the description thereof will not be repeated.

  The two types of frame members having different shapes and sizes can be made of aluminum together with the side frame portions 52 and 52a combined therewith. In the case of aluminum, an oxide film is formed on the surface, so that the metal can be prevented from corroding even if cooling water is scattered and adhered. In addition, about the material of a support frame, it is also possible to comprise using arbitrary materials, such as a plastics.

  Regarding the vertical frame portions 52 and 52 a, the middle frame member 53 that is the first frame member is disposed inside the support frame 51, and the end frame members 54 and 54 a that are the second frame members are disposed outside the support frame 51. And are screwed together at the mated position. The details of these fixing structures are the same as those in the case of the horizontal frame portion 60, and thus the description thereof will be omitted. Further, it is obvious that the arrangement of the middle frame member and the end frame member may be the same as that of the horizontal frame portion 60.

  As described above, in the auxiliary cooling device provided for cooling the heat radiating portion of the outdoor unit 1, by providing the vertical frame portions 52 and 52a and the horizontal frame portions 60 and 60a of the support frame so that the length can be changed. Even when the size of the outdoor unit 1 is changed, it is possible to easily change the length of the vertical frame portions 52 and 52a or the horizontal frame portions 60 and 60a. In addition, when producing many types of outdoor units, the vertical frame portions 52 and 52a or the horizontal frame portions 60 and 60a can be used in common by adjusting the length between models that are not greatly different in size. Is possible. As a result, it is possible to prepare a small number of types of frame members and easily manage the stock of materials in the factory. Further, since the work of assembling the support frame 51 can be easily performed, the workability when installing the auxiliary cooling device is improved, the work content is simplified, and the work time can be shortened. it can.

  In the auxiliary cooling device 40, three pressing members 55 a, 55 b, 55 c (in the case of integration) are provided at predetermined intervals in the vertical direction on the front and back sides of the cooling mat 21 between the horizontal frame portions 60, 60 a. 55 is used). The pressing member 55 restricts the side surface from the thickness direction so that the cooling mat 21 is not curved or deformed. In this embodiment, the number of pressing members 55 is three, but the number can be increased or decreased according to the size of the support frame 51, that is, the length of the vertical frames 52 and 52a. Each pressing member 55 is fixed to the side frame portions 52 and 52a by screws so as to be positioned on both the front and back surfaces of the auxiliary cooling device 40. At this time, in order to absorb an error between the position of the screw hole of the support frame 51 and the attachment hole of the pressing member 55, one attachment hole can be formed as a long hole.

  Although the cooling mat 21 is generally manufactured in a thin mat shape and is easily affected by wind and suction air flow, the holding members 55 extending in the lateral direction press against the cooling mat 21 on the front and back sides of the cooling mat 21. To bend and deform. That is, the cooling mat 21 is restricted from being bent and deformed from the original flat shape in the support frame 51 to the in-plane outside of the support frame 51 by receiving a strong wind. In addition, due to the regulation of the cooling mat 21 by the holding member 55, the cooling water flowing through the cooling mat 21 in the bent state may be directly scattered or dripped onto the floor without flowing down the cooling mat 21. It is prevented in advance.

  3 to 5 are partial cross-sectional views of the auxiliary cooling device 40 shown in FIG. 1, respectively, and FIG. 3 is a cross-sectional view at a position where an engagement tool as shown by AA in FIG. 1 is not provided. 4 is a cross-sectional view at a position where an engaging tool as shown by BB in FIG. 1 is provided. 5A is a partial plan view of a pressing member used in the auxiliary cooling device 40 shown in FIG. 1, and FIG. 5B is a plan view showing another form of the pressing member. The holding member 55 includes an elongated plate-like main body 80 extending in parallel to the installation surface of the cooling mat 21, and an upper rib portion 81 extending outward from the cooling mat 21 from the upper edge of the elongated plate-like main body 80. When the presser member 55 is composed only of the elongated plate-shaped main body 80, the direction in which the bending rigidity of the plate is weak becomes the same as the direction of bending (curvature deformation) of the cooling mat 21, and the bending control action of the cooling mat as the pressing member 55 is sufficient. I can't get it. By providing the upper rib portion 81 extending outward from the upper edge of the elongated plate-like main body 80, the bending rigidity of the presser member 55 can be dramatically increased, and the bending of the cooling mat 21 when attached to the support frame 51 is achieved. The bending rigidity in the same direction as the direction can be reliably increased. Since the upper rib portion 81 extends outward from the cooling mat 21, the cooling water does not prevent the cooling mat 21 from flowing down.

  The holding members 55 are arranged to face each other with the cooling mat 21 sandwiched between the front and back sides. By disposing the pressing member 55 in this way, the cooling mat 21 is regulated on the front and back at the same height position, and the effect of regulating the bending deformation of the cooling mat 21 can be most effectively exhibited. That is, the elongated plate-like main bodies 80, 80 of the pressing members 55, 55 facing each other sandwich the cooling mat 21 by the vertical width of the plates, and restrict the deformation of the cooling mat 21 to either the front or back. .

  Since the upper rib portion 81 is formed so as to extend obliquely upward, as shown in FIG. 3, it is possible to receive water scattered from the cooling mat 21 above the pressing member 55. Further, the received water flows down on the inclined surface of the upper rib portion 81 so as to be automatically collected by the cooling mat 21 and can further flow down the cooling mat 21 below.

  The pressing member 55 also includes a lower rib portion 82 that extends inward of the cooling mat 21 from the lower edge of the elongated plate-shaped main body 80. Similar to the upper rib portion 81, the lower rib portion 82 has an effect of increasing the bending rigidity of the pressing member 55, and further increases the bending rigidity of the pressing member 55 together with the upper rib portion 81. Further, the lower rib portion 82 enters the region of the cooling mat 21 and positively sandwiches the cooling mat 21 in cooperation with the lower rib portion 82 of the opposing pressing member 55. Therefore, the deformation of the cooling mat 21 can be further suppressed. Since the gap 83 extending from the cooling mat 21 is left between the opposed lower rib portions 82, 82, there is no problem in the flow of cooling water.

  The presser members 55, 55 arranged opposite to each other can be engaged with each other by an engaging tool 85. The engagement tool 85 is generally formed by bending a spring wire, and includes an engagement main body 86 and engagement portions 87 and 87 formed at both ends thereof. In this embodiment, each engaging portion 87 has a form in which the tip end portion of the lower rib portion 82 is engaged with spring force at at least two places. For example, when the presser member 55 is manufactured by extrusion molding of aluminum, the smaller the number of perforations, the more convenient it is. Therefore, the engaging tool 85 is engaged by a spring force and is attached to the presser member 55. A form that does not require post-processing is preferred. However, the present invention is not limited to this, and forms such as engagement holes and engagement hooks may be employed. By engaging the presser members 55 and 55 arranged opposite to each other with the engaging tool 85, the connection rigidity of the presser members 55 and 55 is further enhanced. In addition, since the distance between the pressing members 55 and 55 is fixed by the engagement tool 85, the effect of restricting the deformation of the cooling mat 21 is further enhanced.

  As described above, the cooling mat 21 is divided into two types of mats 21a and 21b having a width in the left-right direction, and the engaging tool 85 can be disposed at the boundary between the adjacent cooling mats 21b and 21b. By disposing the application position of the engagement tool 85 at the boundary between the cooling mats 21b and 21b divided in the left-right direction, the operation of engaging and disengaging the engagement tool 85 with respect to the holding members 55 and 55 is performed by the cooling mat. It does not need to be done through the interior and is greatly simplified.

  As shown in FIG. 5B, the lower rib portion 82 may be provided with an uneven portion 84 that meshes with the cooling mat 21. In FIG. 5 (b), the pressing member shown in FIG. 5 (a) and its equivalent parts are denoted by the same reference numerals, and description thereof will be omitted. The engaging tool 85 also has a function of restricting movement of the mats 21a and 21b in units of blocks. However, the concave and convex portions 84 provided on the lower rib portion 82 are directly meshed with the cooling mat 21 so that the cooling mat 21 is engaged. It is possible to prevent 21 from being displaced in the in-plane direction. The concave and convex portions 84 are directly formed as triangular corrugations on the lower rib portions 82 of the pressing member 55 facing each other as shown in the figure, but the present invention is not particularly limited to this mode. The formation range and the like can be changed as appropriate. In the illustrated example, the concave and convex portions 84 and 84 of the both pressing members 55 are formed so that the convex portions and the concave portions face each other, but are formed so as to be shifted so that the convex portions and the concave portions face each other. May be. Or you may attach the separate thing in which the unevenness | corrugation was formed to the lower rib part 82. FIG.

  The left and right sizes of the auxiliary cooling device 40 can vary depending on the model, scale, structure, etc. of the outdoor unit 1, and accordingly, the support frame 51 with different left and right sizes is prepared, or as described above. A structure in which the support frame 51 is variable in the left and right length is adopted. As shown in FIGS. 1 and 2, the presser member 55 is attached to the central presser member 55 with reference numerals, and as shown in FIG. 6, the first presser member 56 and the second presser member 57 divided into left and right parts. It consists of. FIG. 6 is a perspective view illustrating an example of a variable length structure of the pressing member 55. In particular, as shown in FIG. 6, the first presser member 56 and the second presser member 57 can be connected to each other so that the overlapping length L can be changed, thereby corresponding to the left and right sizes of the support frame 51. The overall length can be changed.
