Description

  The present invention relates to an outdoor unit and a manufacturing method thereof.

  In general, an air conditioner includes an electrical component on which a power element such as an inverter circuit that controls a compressor is mounted. Since the power element generates heat during operation of the air conditioner, various means have been proposed for cooling the power element so that the power element does not reach a temperature higher than the operable temperature.

  For example, Patent Document 1 discloses an outdoor unit that cools an electrical component with a component in which a refrigerant pipe through which a refrigerant flows and a heat radiation fin are joined. In the outdoor unit of Patent Document 1, a part of the partition plate 11a extends in the horizontal direction from the partition plate 11 arranged in the vertical direction that partitions the machine room and the heat exchange chamber. The electrical component module 10 is fixed to the lower surface of a part 11a of the partition plate by screwing a screw from below. Furthermore, the component which joined the radiation fin 10a and the refrigerant | coolant piping 20a is being fixed to the lower surface of the electrical component module 10 by screwing a screw from below. In this outdoor unit, a part in which the heat radiating fins 10a and the refrigerant pipe 20a are joined is prepared in advance and assembled at a position where the electrical component module is disposed, and then the electrical component module is set at the disposed position.

JP 2008-760008 A (5th page, FIG. 10)

  However, as in the outdoor unit of Patent Document 1, when the electrical component module is disposed after the refrigerant circuit component including the parts in which the radiation fins 10a and the refrigerant pipe 20a are joined is assembled on the base of the outdoor unit. Has the following problems. That is, in such a case, when the electrical component module is attached to or detached from the part 11a of the partition plate and the part where the radiating fin 10a and the refrigerant piping 20a are joined, the electrical component module is a refrigerant circuit such as a refrigerant piping. There is a possibility that the electric component module and the refrigerant pipe may be damaged by colliding with the structure, and there is a problem that the electric component module cannot be safely attached or detached.

  Therefore, the present invention has been made in view of such a point, and an object of the present invention is to provide an outdoor unit capable of safely attaching or removing an electrical component module and a manufacturing method thereof.

  The outdoor unit of the present invention is used for an air conditioner having a refrigerant circuit (18) through which a refrigerant circulates. This outdoor unit includes a casing (30), an electrical component module (35), a cooling member (100), and fixing means (B1). The electrical component module (35) has a power element (56a) and is disposed at a predetermined position in the casing (30). The cooling member (100) is thermally connected to the power element (56a), and a cooling part (37) for cooling the power element (56a) by the refrigerant of the refrigerant circuit, and cooling the refrigerant A pair of pipes provided on the upstream side and the downstream side of the cooling part (37) for sending to the part (37) side and capable of bending and deforming in a direction to separate the cooling part (37) from the power element (56a) (18b). The fixing means (B1) fixes the cooling unit (37) to the electrical component module (35) in a state where the cooling unit (37) is thermally connected to the power element (56a).

  In this configuration, a cooling member (100) having a pair of pipes (18b) that can be bent and deformed in a direction away from the power element (56a) is provided. Therefore, the structure of the refrigerant circuit (18) including the cooling member (100) is disposed in advance on the base, and then the electrical component module (35) is disposed at the planned position (M). Even in the case of adopting the method, the cooling part (37) can be separated from the planned placement position (M) of the electrical component module (35) by bending the pair of pipes (18b) in the separating direction. Therefore, a large space can be created between the planned arrangement position (M) and the cooling part (37). As a result, when the electrical component module (35) is disposed at the planned disposition position (M), the electrical component module (35) is prevented from colliding with the refrigerant circuit component such as the cooling member (100). Thus, the electrical component module (35) can be safely arranged at a predetermined arrangement position.

  The outdoor unit of the present invention is provided in a first engagement member (71) provided in the electrical component module (35) and a support (39) fixed to the casing (30) or the casing (30). It is preferable to further include the second engaging member (81). The second engaging member (81) guides the electrical component module (35) between a position where the electrical component module (35) and the cooling unit (37) are separated from each other and the disposition position. It is possible to slide the first engagement member (71).

  In this configuration, the first engagement member (71) is guided to the second engagement member (81), and the electrical component module (35) is moved from the separation position to the installation position along a predetermined slide movement path. Can be made. Thereby, when arrange | positioning an electrical component module (35), it can further suppress that an electrical component module (35) collides with refrigerant circuit (18) structural bodies, such as a member for cooling (100). The electrical component module (35) can be disposed more safely and accurately.

  The second engagement member (81) has a vertical portion (83) capable of slidingly moving the first engagement member (71) in the vertical direction, and the electrical component module (35) is disposed on the arrangement position side. It is preferable that the sliding direction of the first engagement member (71) in the vertical portion (83) when guiding to the lower side is downward.

  In this configuration, since the sliding movement direction when guiding the electrical component module (35) to the installation position is from the top to the bottom, the electrical component module (35) is disposed above the installation position. The electrical component module (35) can be disposed at the disposition position by sliding the first engagement member (71) along the vertical portion (83) from above to below. As a result, the electrical component module (35) can be slid using its own weight, so that the load can be reduced in the case of manual work by an operator, and in the case of work by a machine. Consumption can be saved.

  The second engagement member (81) can slide the first engagement member (71) to the back side and the front side, and the vertical portion (83) from the front side to the back side. Preferably, it has a lateral portion (85) extending to the top of the.

  In this configuration, since the second engagement member (81) further includes the lateral portion (85), the first engagement member (71) is slid to the back side along the lateral portion (85). Thus, the first engagement member (71) can be safely and accurately moved from the horizontal portion to the vertical position where it is relayed.

  The manufacturing method of the present invention includes an electrical component module (35) in which a power element (56a) is mounted in a casing (30), and a cooling unit (37) for cooling the power element (56a), And a cooling member (100) having a pair of pipes (18b) provided on the upstream side and the downstream side of the cooling unit (37) so that the refrigerant of the refrigerant circuit (18) passes through the cooling unit (37). ) And an outdoor unit manufacturing method. The manufacturing method includes a step of disposing a component of the refrigerant circuit (18) including the cooling member (100) on a base, and the cooling unit (37) is disposed of the electrical component module (35).

A step of disposing at the planned disposition position (M), a step of returning the cooling unit (37) to the back side and bringing the cooling unit (37) into contact with the electrical component module (35), and the cooling unit Fixing (37) to the electrical component module (35) by fixing means (B1).

  In this method, after the refrigerant circuit component including the cooling member (100) is disposed on the base, the cooling unit (37) is in front of the planned disposition position (M) of the electrical component module (35). Since the pair of pipes (18b) are bent so as to be separated from each other, a large space can be created between the planned arrangement position (M) and the cooling part (37). Since the electric component module (35) is arranged at the planned arrangement position (M) in such a bent state, the electric component module (35) is prevented from colliding with the cooling member (100) or the like. The electrical component module (35) can be safely placed at the planned placement position (M). Moreover, after arrange | positioning an electrical component module (35) in the arrangement | positioning planned position (M), a cooling part (37) is returned to the back | inner side of a casing (30), and a cooling part (37) is made into an electrical component module (35). The cooling part (37) is thermally contacted with the power element (56a) by fixing the cooling part (37) to the electrical component module (35) by the fixing means (B1) in a state of being in contact with the power element (B1).

  FIG. 1 shows a piping system of an air conditioner 10 according to the present embodiment. The air conditioner 10 is a heat pump type air conditioner 10 capable of cooling operation and heating operation. As shown in FIG. 1, the air conditioner 10 includes an outdoor unit 11 installed outside and an indoor unit 12 installed indoors. The outdoor unit 11 and the indoor unit 12 are connected via a first connection pipe 13 and a second connection pipe 14. The air conditioner 10 is provided with a refrigerant circuit 18 in which pipes including the connection pipes 13 and 14 are connected in a closed circuit shape. The refrigerant circuit 18 is mainly provided with an indoor heat exchanger 20, a compressor 23, an oil separator 24, an outdoor heat exchanger 25, an expansion valve 26 that is an expansion mechanism, an accumulator 27, and a four-way switching valve 28. In the refrigerant circuit 18, a refrigerant is circulated to perform a vapor compression refrigeration cycle.

  The indoor heat exchanger 20 is a heat exchanger for exchanging heat between the refrigerant and indoor air, and is provided in the indoor unit 12. As the indoor heat exchanger 20, for example, a cross fin type fin-and-tube heat exchanger or the like can be employed. An indoor fan (not shown) for blowing indoor air to the indoor heat exchanger 20 is provided in the vicinity of the indoor heat exchanger 20.

  The compressor 23, the oil separator 24, the outdoor heat exchanger 25, the expansion valve 26, the accumulator 27, and the four-way switching valve 28 are provided in the outdoor unit 11. These are all housed in the casing 30 (see FIGS. 2 to 4).

  The compressor 23 has a suction port, a compression mechanism, and a discharge port. The refrigerant sucked from the suction port is compressed by the compression mechanism and discharged from the discharge port. As the compressor 23, various compressors, such as a scroll compressor, are employable, for example.

  The oil separator 24 is for separating the lubricating oil from the mixed fluid of the lubricating oil and the refrigerant discharged from the compressor 23. The separated refrigerant is sent to the four-way switching valve 28, and the lubricating oil is returned to the compressor 23.

  The outdoor heat exchanger 25 is for exchanging heat between the refrigerant and outdoor air. For example, a cross fin type fin-and-tube heat exchanger or the like can be adopted. An outdoor fan 31 for blowing outdoor air to the outdoor heat exchanger 25 is provided in the vicinity of the outdoor heat exchanger 25.

  The expansion valve 26 is disposed between the outdoor heat exchanger 25 and the indoor heat exchanger 20 in the refrigerant circuit 18, and expands the refrigerant that has flowed in to reduce the pressure to a predetermined pressure. As the expansion valve 26, for example, an electronic expansion valve 26 having a variable opening can be employed.

  The accumulator 27 is for gas-liquid separation of the flowing refrigerant, and is arranged between the suction port of the compressor 23 and the four-way switching valve 28 in the refrigerant circuit 18. The gas refrigerant separated by the accumulator 27 is sucked into the compressor 23.

  The four-way switching valve 28 is provided with first to fourth ports. The four-way switching valve 28 includes a first state (state indicated by a solid line in FIG. 1) in which the first port and the third port are communicated with each other and a second port and a fourth port, and the first port and the fourth port. Can be switched to a second state (state indicated by a broken line in FIG. 1) in which the second port and the third port are communicated simultaneously. The first port is connected to the discharge port of the compressor 23 via the oil separator 24, the second port is connected to the suction port of the compressor 23 via the accumulator 27, and the third port is connected to the outdoor It is connected to the heat exchanger 25 and the fourth port is connected to the indoor heat exchanger 20 via the first connection pipe 13. When the air conditioner 10 performs the cooling operation, the four-way switching valve 28 is switched to the first state, and when the heating operation is performed, the four-way switching valve 28 is switched to the second state.

  A refrigerant jacket 37, which is a cooling unit for cooling the heat generating part of the electrical component module 35, is joined to the liquid side pipe of the refrigerant circuit 18. In the illustrated example, the liquid side pipe to which the refrigerant jacket 37 is joined is a liquid side pipe between the outdoor heat exchanger 25 and the expansion valve 26 in the refrigerant circuit 18, but the refrigerant to which the refrigerant jacket 37 is joined. The piping is not limited to this. However, considering the cooling capacity, the refrigerant jacket 37 is preferably joined to the liquid side pipe.

  In the pipe joined to the refrigerant jacket 37, the refrigerant condensed by the outdoor heat exchanger 25 flows during the cooling operation, and the refrigerant condensed by the indoor heat exchanger 20 and decompressed by the expansion valve 26 flows during the heating operation. . Although the temperature of these refrigerant | coolants changes with operating conditions etc., it is about 40-45 degreeC at the time of air_conditionaing | cooling operation, for example.

  The refrigerant jacket 37 is formed in a flat shape, and is configured to be surface-bondable at a predetermined position of the electrical component module 35. The electrical component module 35 is an electrical component assembly for performing operation control of the refrigerant circuit 18, and is provided in the outdoor unit 11. Detailed configurations of the electrical component module 35 and the refrigerant jacket 37 will be described later.

  As shown in FIGS. 2 to 4, the outdoor unit 11 includes a bottom plate 30 a as a base, a side plate 30 b erected on the peripheral edge of the bottom plate 30 a, and a top plate installed between the upper ends of the side plates 30 b. And a casing 30 having 30c, and has a substantially rectangular parallelepiped appearance as a whole.

  The outdoor unit 11 is provided with a partition plate 39 that divides the space in the casing 30 into two spaces. The partition plate 39 has a size extending from the lower end portion to the upper end portion of the space in the casing, and is fixed to the bottom plate 30 a so as to be erected on the bottom plate 30 a of the casing 30. The partition plate 39 also has a role as a support for supporting the electrical component module 35. By this partition plate 39, the space in the casing is partitioned into a heat exchange chamber 40 in which the outdoor heat exchanger 25 and the outdoor fan 31 are accommodated, and a machine room 41 in which the compressor 23, the electrical component module 35, and the like are accommodated. ing. The heat exchange chamber 40 is located on the left side when viewed from the front side, and the machine room 41 is located on the right side when viewed from the front side. In addition, the blower outlet which blows off the air of the heat exchange chamber 40 out of the casing 30 is opened in the front surface of the casing 30.

  The outdoor heat exchanger 25 is installed on the bottom plate 30 a of the casing 30 and has a size ranging from the lower end portion to the upper end portion of the heat exchange chamber 40. The outdoor heat exchanger 25 is formed in an L shape in plan view, and is disposed along the back side plate 30b and the left side plate 30b. The rear end portion of the partition plate 39 is coupled to the end portion of the outdoor heat exchanger 25, and the front end portion of the partition plate 39 is coupled to the front casing side plate 30b.

  As shown in FIGS. 3 and 4, the machine room 41 is formed so as to occupy the whole in the front-rear direction in the right side portion of the space in the casing. An electrical component module 35 is disposed on the front side in the machine room 41. That is, the electrical component module 35 is installed in the vicinity of the side plate 30 b in a posture in which the front surface thereof is approximately parallel to the side plate 30 b on the front side of the casing 30. Therefore, when the front side plate 30b of the casing 30 is removed, the front surface of the electrical component module 35 is exposed on the front side. Refrigerant circuit components (refrigerant circuit components) such as a refrigerant pipe and an accumulator 27 are disposed on the back side (rear side) of the electrical component module 35.

  The electrical component module 35 is disposed at an intermediate portion in the height direction in the machine room 41, and the upper and lower portions of the electrical component module 35 are spaces. The electrical component module 35 is coupled to the partition plate 39 at one end (left end) in the width direction, and is coupled to the side plate 30b of the casing 30 at the other end (right end).

  The electrical component module 35 includes a holding member 44 as a module body, a circuit board 45, a terminal block 46, a back protective cover 47 as a protective member, a reactor 94, and a reactor 94 for attaching the reactor 94 to the holding member 44. And an attachment plate 42.

  The holding member 44 includes a main member 51 configured to be coupled to the side plate 30 b and the partition plate 39 of the casing 30, and a resin-made interposing member 52 coupled to the main member 51. The main member 51 is formed by punching a proper portion of a member made of sheet metal and bending it into a predetermined shape. The main member 51 includes a rectangular main surface portion 51a, a side surface portion 51b bent from a side end portion of the main surface portion 51a, and a top surface portion 51c bent from an upper end portion of the main surface portion 51a. The interposed member 52 is coupled to the main surface portion 51 a of the main member 51, and suppresses the heat of the circuit board 45 from being transmitted to the main member 51.

  The circuit board 45 includes a rear substrate 54 (see FIGS. 5 and 6) disposed on the rear surface side of the main surface portion 51 a of the main member 51 and a front surface disposed on the front surface side of the main surface portion 51 a of the main member 51. And a side substrate 55 (see FIG. 2).

  The back substrate 54 includes a first substrate portion 54a on which a plurality of electrical components 56 including a power element 56a (see FIG. 7) and an element 56b such as a capacitor other than the power element 56a are mounted, and an element 56b other than the power element 56a. And a second substrate part 54b on which a plurality of electrical components 56 are mounted. Examples of the electrical component 56 mounted on the second substrate unit 54b include a noise filter. The second substrate portion 54b is fixed to the main member 51 so that the electrical component 56 is on the back side.

  The second substrate portion 54b is coupled to the upper portion of the main surface portion 51a of the main member 51, and the first substrate portion 54a is disposed below the second substrate portion 54b. The first substrate portion 54 a is coupled to an interposed member 52 that is coupled to the main surface portion 51 a of the main member 51. That is, the first substrate portion 54 a is indirectly coupled to the main member 51, while the second substrate portion 54 b is directly coupled to the main member 51.

  Examples of the power element 56a provided in the first substrate portion 54a include a compressor control inverter and a fan motor control module. That is, a plurality of power elements 56a are mounted on the first substrate portion 54a. These power elements 56a are mounted on the front surface of the first substrate portion 54a. On the other hand, an electrical component 56 other than the power element 56a is mounted on the back surface of the first substrate portion 54a, and a plate-shaped electrical component member 57 is provided. The electrical member 57 is joined to the first substrate portion 54a so as to be perpendicular to the first substrate portion 54a.

  Many electrical components (not shown) other than the power element 56 a are mounted on the front surface of the front substrate 55. The electrical components mounted on the front substrate 55 include electrical components that are operated by an operator during trial operation and maintenance, electrical components that can display the control operation status, and the like. The front side substrate 55 is disposed mainly on the upper side in the main surface portion 51 a of the main member 51. That is, the front substrate 55 is disposed on the main surface portion 51a at a location different from a location where a heat transfer plate 60 described later is disposed.

  A heat transfer plate 60 is surface-bonded to the front surface of the plurality of power elements 56a mounted on the first substrate portion 54a (see FIG. 7). An arrow D in FIG. 7 indicates a direction on the front side. That is, the heat transfer plate 60 is a member having a size including the positions where the plurality of power elements 56a are disposed, and is made of a material having high thermal conductivity such as aluminum.

  The first substrate portion 54a is coupled to the back surface of the interposition member 52 coupled to the back surface of the main surface portion 51a of the main member 51. However, the first substrate portion 54a has heat transfer to the main surface portion 51a and the interposition member 52 of the main member 51. An opening 61 (see FIG. 6) having a size capable of inserting the plate 60 is formed. The heat transfer plate 60 is exposed to the front side of the main member 51 through the opening 61. The opening 61 is L-shaped as indicated by a broken line in FIG.

  As shown in FIGS. 7 to 9, the outdoor unit 11 of the present embodiment includes a cooling member 100 for cooling the power element 56 a via a heat transfer plate 60. The cooling member 100 includes a refrigerant jacket 37, a cooling refrigerant pipe 18a for cooling the refrigerant jacket 37, and a pair of pipes 18b and 18b connected to both ends of the refrigerant pipe 18a.

  The refrigerant jacket 37 is surface-bonded to the front surface 60 a of the heat transfer plate 60. The refrigerant jacket 37 is fixed to the heat transfer plate 60 by screw fastening with bolts B1 as fixing means described later. The refrigerant jacket 37 is made of a thick plate material made of a material having high thermal conductivity such as aluminum, and a cooling refrigerant pipe 18a of the refrigerant circuit 18 is joined thereto. That is, the refrigerant jacket 37 joined to the cooling refrigerant pipe 18 a through which the refrigerant in the refrigerant circuit 18 flows is thermally connected to the power element 56 a via the heat transfer plate 60. Accordingly, the heat transfer plate 60 is joined to the power element 56a and functions as a receiving portion to which the refrigerant jacket 37 can be thermally connected.

  The refrigerant jacket 37 is formed in a horizontally long rectangular shape, and a groove extending in the longitudinal direction is formed on the front surface. Two grooves are provided on the upper and lower sides, and are parallel to each other. The cooling refrigerant pipe 18 a bent into a U shape is press-fitted into the two grooves, whereby the cooling refrigerant pipe 18 a is joined to the refrigerant jacket 37. The cooling refrigerant pipe 18 a fixed to the refrigerant jacket 37 functions as a cooling passage through which the refrigerant in the refrigerant circuit 18 flows.

  The cooling refrigerant pipe 18 a joined to the refrigerant jacket 37 is a part of a pipe (liquid side pipe) provided between the outdoor heat exchanger 25 and the expansion valve 26 in the refrigerant circuit 18. Are connected to the upper ends of a pair of pipes 18b extending in the vertical direction. That is, one end of the cooling refrigerant pipe 18a formed in the U-shape is connected to the lower end of the outdoor heat exchanger 25 via one pipe 18b extending in the vertical direction, and the other end is in the vertical direction. It is connected to the expansion valve 26 through the other pipe 18b extending to.

  The pair of pipes 18b are respectively provided on the upstream side and the downstream side of the refrigerant jacket 37 in order to send the refrigerant of the refrigerant circuit to the refrigerant jacket 37 side and cool the refrigerant jacket 37, and each upper end portion is U-shaped cooling. It is the refrigerant | coolant piping each joined to the both ends of the refrigerant | coolant piping 18a. As described above, the air-conditioning apparatus of the present embodiment can switch between the heating operation and the cooling operation, and the flow direction of the refrigerant flowing through the refrigerant circuit is reversed during the heating operation and the cooling operation. Therefore, by switching the mode between the heating operation and the cooling operation, the relative position of each pipe 18b with respect to the refrigerant jacket 37 is switched to the upstream side or the downstream side, respectively. As shown in FIGS. 2 and 3, the pair of pipes 18 b are arranged on one side plate 30 b (the right side plate 30 b in this embodiment) side in the width direction of the machine room 41.

  Since the pair of pipes 18b extend in the vertical direction and are arranged side by side when viewed from the front side, they can be bent and deformed toward the front side and the back side.

  The pair of pipes 18b mainly has three parts. That is, the pair of pipes 18b are positioned on the back side of the refrigerant pipe 18a and extend in the vertical direction, and are bent from the upper end of the lower part 181 and are inclined obliquely upward toward the front side. Each has an intermediate part 182 and an upper part 183 that is bent from the upper end of the intermediate part 182 and extends in the vertical direction and is connected to the cooling refrigerant pipe 18a. In this way, the pair of pipes 18b has a pipe (intermediate part 182) inclined in part. Thereby, even if the length of the height direction is the same compared with the case where the whole is linear, for example, the displacement of the upper part 183 at the time of bending deformation can be increased.

  In addition, the diameter and thickness of the pair of pipes 18b are adjusted so as to withstand the pressure of the refrigerant and to be rigid enough to bend and deform. The diameter and thickness of the pipe 18b may be constant from the upper end to the lower end of the pipe 18b. For example, a part of the pipe 18b may have a smaller diameter and / or thickness than other parts. Since the portion having a small diameter and / or thickness is more easily bent and deformed than the other portions, the pair of pipes 18b are easily bent and deformed during manufacturing, which will be described later, and workability is improved. Further, in such a configuration, it is possible to selectively bend a portion having a smaller diameter and / or thickness than other portions.

  The mounting plate 42 is interposed between the two reactors 94 and the top surface portion 51c of the holding member 44, and protrudes from the holding member 44 to the near side in a substantially horizontal direction.

  Next, the manufacturing method of the outdoor unit 11 of this embodiment is demonstrated.

  First, as shown to Fig.10 (a), the partition plate 39, the structure of a refrigerant circuit, etc. are arrange | positioned on the baseplate 30a as a base. Examples of components of the refrigerant circuit 18 include an outdoor heat exchanger 25, a compressor 23, an oil separator 24, an expansion valve 26, an accumulator 27, a four-way switching valve 28, and a cooling member 100. At this time, the electrical component module 35 is not yet disposed on the bottom plate 30a.

  In a state before the electrical component module 35 is disposed on the bottom plate 30a, a space of a predetermined size is provided at the planned placement position M of the electrical component module 35, and the refrigerant is located on the front side of this space. A jacket 37 and a refrigerant pipe 18a are arranged. The position of the refrigerant jacket 37 before the electric component module 35 is arranged is such that the surface of the refrigerant jacket 37 is the heat transfer of the electric component module 35 when the electric component module 35 is arranged at a predetermined arrangement position. The position is adjusted so as to be in surface contact with the front surface 60a of the plate 60 or in the vicinity thereof.

  Next, as shown by a two-dot chain line in FIG. 10A, the pair of pipes 18b is bent so that the refrigerant jacket 37 is separated from the front side (front side) with respect to the position M where the electrical component module 35 is to be disposed. In addition, a large space is created between the planned placement position M of the electrical component module 35 and the refrigerant jacket 37.

  The bending process of bending the pair of pipes 18b to the front side may be performed manually by an operator or using an automated manufacturing apparatus, but the pair of pipes 18b is used for the cooling member 100. It is preferable that the structure bends to the front side by its own weight. On the front side of the refrigerant jacket 37 and the refrigerant pipe 18a in the machine room 41, a space in which other members are not provided is provided in advance so that these can move forward. In the indoor unit 11 of the present embodiment, no other member is disposed between the refrigerant jacket 37 and the refrigerant pipe 18a and the front side plate 30b.

  In order to bend the pair of pipes 18b to the front side by their own weight, for example, as shown in FIG. 3, the upper part of the pair of pipes 18b is arranged on the front side rather than the lower part, and the cooling member A method in which the cooling refrigerant pipe 18a and the refrigerant jacket 37 are arranged on the upper portion of 100 is exemplified. That is, the cooling member 100 shown in FIG. 3 has a structure in which the center of gravity of the cooling member 100 is positioned at the top and the weight of the top is applied to the front side.

  In this embodiment, by providing an intermediate part 182 that extends upward while inclining to the front side between the lower part 181 and the upper part 183, the upper part of the pair of pipes 18b is made to be more than the lower part. Arranged on the front side. In addition, as another means which arrange | positions an upper site | part to the front side rather than a lower site | part, you may use a pair of linear piping 18b extended upwards, for example, inclining to the front side.

  In addition, the degree to which the pair of pipes 18b are bent to the front side by their own weight is such that a necessary space can be secured between the planned arrangement position M and the refrigerant jacket 37 and the electrical component module 35 can be safely attached. Adjust. In order to adjust the degree of bending, for example, there is a method of adjusting the weight of the refrigerant jacket 37, the weight of the cooling refrigerant pipe 18a, the rigidity of the pair of pipes 18b, and the like. Further, in order to adjust the amount of bending in the bending step, for example, a weight may be attached to the upper part of the cooling member 100 such as the refrigerant jacket 37. This weight is removed as necessary after the refrigerant jacket 37 is fixed to the heat transfer plate 60.

  Further, when this bending process is performed manually by an operator, in order to improve workability, the pair of pipes 18b is temporarily fixed in a state of being bent to the front side. Temporary fixing means may be provided. Examples of the temporary fixing means include hook-like, plate-like, and rod-like members that are hooked on the refrigerant jacket 37, the refrigerant pipe 18a, the pipe 18b, etc., and hold the cooling member 100 in a posture inclined to the front side. . Such a member may be provided in a member constituting the outdoor unit 11 such as the partition plate 39 and the casing 30, and is provided in a part of the manufacturing apparatus instead of a member constituting the outdoor unit 11. Also good.

  Next, as shown in FIGS. 13A to 13C, the electrical component module 35 is moved from the separation position to a predetermined arrangement planned position M. FIG. 13A is a perspective view showing a state in which the electrical component module 35 is in the separated position, and FIG. 13B is a perspective view showing a state in which the electrical component module 35 is in the relay position. ) Is a perspective view showing a state in which the electrical component module 35 is in the arrangement position (arrangement planned position M).

  This arrangement process includes the following two stages. In the first stage, by sliding the first engagement member 71 from the near side to the far side in a state where the first engagement member 71 is engaged with the lateral portion 85 of the second engagement member 81, The electrical component module 35 is moved from the separation position to the relay position. In the second stage, with the first engagement member 71 engaged with the vertical portion 83 of the second engagement member 81, the first engagement member 71 is slid from above to below, and the electrical component module 35. Is moved from the relay position to the planned placement position M.

  The separation position in the present embodiment is a position closer to the front side (front side) than the relay position, and when the first engagement member 71 is engaged with the lateral portion 85 of the second engagement member 81, that is, the first position. This is the position of the electrical component module 35 when the engaging portions 71 d and 71 e of the first engaging member 71 are placed on the placement path 85 d of the lateral portion 85.

  In the first stage, as shown in FIG. 12A, first, the lower ends of the engaging portions 71 d and 71 e of the first engaging member 71 are placed on the upper surface of the placing path 85 d of the lateral portion 85. Next, in this state, the electrical component module 35 is pushed from the near side toward the far side. At this time, the first engagement member 71 slides back along the lateral portion 85. During the sliding movement of the electrical component module 35, the lower ends of the engaging portions 71d and 71e are in contact with or close to the mounting path 85d of the lateral portion 85. The side wall 85c of the horizontal portion 85 restricts the movement of the lower end portions of the engaging portions 71d and 71e in the left-right direction to some extent during the sliding movement, and prevents the engaging portions 71d and 71e from coming off from the placement path 85d. it can.

  After the engagement portion 71e on the back side exceeds the back end portion of the placement path 85b due to the slide movement, the engagement portion 71e is placed along the guide wall 85d, and only the engagement portion 71d on the near side is placed. The first engagement member 71 is further moved to the back side while being placed on the placement path 85d. Then, after the front engaging portion 71d also exceeds the rear end of the mounting path 85b, the first engaging member 71 is moved with the engaging portions 71d and 71e both along the guide wall 85d. When it is further moved to the back side, the back side engaging portion 71e comes into contact with the back side stopper 88, and the electrical component module 35 is restricted from sliding further to the back side (see FIG. 12B). ). This restriction position is directly above the upper end portion of the vertical portion 83.

  Further, when the first engaging member 71 is moved to the back side with the engaging portions 71d and 71e being along the guide wall 85d, the upper stopper 86 restricts the upward movement of the engaging portions 71d and 71e. Therefore, the 1st engagement member 71 can be moved to the back side further stably.

  In the second stage, first, the lower end portions of the engaging portions 71d and 71e in each first engaging member 71 are inserted into the groove portions 83f and 83g from the upper end of the vertical portion 83, respectively, and the first engaging members 71 are respectively inserted in the vertical portions. Engage with the part 83. At this time, since the corner portion 83h is provided in the engaging portion 83c, even if the positions of the lower end portions of the engaging portions 71d and 71e are slightly shifted, the corner portion 83h causes the engaging portions 71d and 71e to move into the groove portions 83f and 83g. Play the role of guiding to the side. Thus, the engaging portions 71d and 71e are easily inserted into the groove portions 83f and 83g.

  Next, in the state of being inserted in this way, the first engagement members 71 are slid downward to move the electrical component module 35 downward (see FIG. 12C). The electrical component module 35 stops when the leg portions 71b and 71c of the first engaging members 71 come into contact with the horizontal portion 83e of the vertical portion 83, and is disposed at a predetermined position as shown in FIG. Is done.

  Next, the pair of pipes 18 b bent to the front side is returned to the back side, and the refrigerant jacket 37 is brought into contact with the front surface 60 a of the heat transfer plate 60. Next, as shown in FIG. 14A, the refrigerant jacket 37 is fixed to the heat transfer plate 60 by a bolt B1 as a fixing means. Finally, the terminal block 46 is rotated around the bolt B so that the refrigerant jacket 37 and the refrigerant pipe 18 a are covered with the terminal block 46.

  In the case of removing the electrical component module 35 from the installation position at the time of maintenance, parts replacement, etc., for example, the following may be performed. First, the terminal block 46 is rotated from the closed state in which the refrigerant jacket 37 is covered by the terminal block 46 (FIG. 14B) to open the terminal block 46 (FIG. 14A). Next, the bolt B1 that fixes the refrigerant jacket 37 to the heat transfer plate 60 is removed.

  Next, the pair of pipes 18 b are bent to the front side (front side), and the refrigerant jacket 37 is pulled away from the heat transfer plate 60. At this time, if necessary, the cooling member 100 may be temporarily fixed at a position bent by the temporary fixing means.

  Next, the first engagement member 71 is slid upward along the vertical portion 71 (FIG. 12C), and the upper end portions of the inclined portions 71f and 71g of the first engagement member 71 contact the upper stopper 86. The electrical component module 35 is moved from the installation position to the relay position by stopping the upward sliding movement at the contact (FIG. 13B). When the first engaging member 71 is slid upward with respect to the vertical portion 71 in this way, the upper portions of the first engaging member 71 are the lower ends of the horizontal portions 85 by providing the inclined portions 71f and 71g. It is possible to suppress a step between the partition plate 39 and the partition plate 39. Thereby, the 1st engagement member 71 can be slid stably. At this relay position, the first engagement member 71 is disengaged from the vertical portion 71 (FIG. 12B).

  Next, the electrical component module 35 is moved to the near side with the upper end portions of the inclined portions 71f and 71g abutting or approaching the upper stopper 86 and the engaging portions 71d and 71e abutting or approaching the fixing portion 85a. Let If it moves to some extent, the lower end part of engaging part 71d, 71e will be mounted on the mounting path 85d. In this state, the first engagement member 71 is further slid along the lateral portion 85 to move the electrical component module 35 to the separation position. Thereby, the electrical component module 35 can be safely removed from the arrangement position.

  Here, the operation | movement operation | movement of the air conditioning apparatus 10 of this embodiment is demonstrated.

  In the air conditioner 10, when the cooling operation is performed, the four-way switching valve 28 is switched to the first state. The refrigerant compressed by the compressor 23 is separated by the oil separator 24 and then flows into the outdoor heat exchanger 25 via the four-way switching valve 28. This refrigerant is condensed by exchanging heat with outdoor air in the outdoor heat exchanger 25 and becomes a liquid refrigerant. The liquid refrigerant flows upward in one pipe 18 b extending in the vertical direction, and then flows through the refrigerant pipe 18 a fixed to the refrigerant jacket 37. At this time, if the power element 56a generates heat by driving the compressor 23 and the fan motor, the heat transfer plate 60 is heated by the heat generated by the power element 56a. However, the heating element 60a is heated by the refrigerant flowing through the refrigerant pipe 18a. The heat transfer plate 60 is cooled via the refrigerant jacket 37.

  The refrigerant that has flowed through the refrigerant pipe 18 a flows downward through the other pipe 18 b that extends in the vertical direction, and then is decompressed by the expansion valve 26 and flows into the indoor heat exchanger 20. This refrigerant is vaporized by exchanging heat with indoor air in the indoor heat exchanger 20. The indoor air is cooled and blown into the room by this heat exchange. The refrigerant heated and evaporated by the room air flows into the accumulator 27 via the four-way switching valve 28. In the accumulator 27, the refrigerant is gas-liquid separated, and the gas refrigerant separated here is sucked into the compressor 23. During the cooling operation, the refrigerant circulation is continuously performed.

  On the other hand, during the heating operation, the four-way switching valve 28 is switched to the second state. The refrigerant discharged from the compressor 23 is introduced into the indoor heat exchanger 20 via the oil separator 24 and the four-way switching valve 28. In the indoor heat exchanger 20, the refrigerant is condensed by exchanging heat with room air. By this heat exchange, the room air is heated and blown into the room. The refrigerant cooled and condensed by the indoor air is expanded by the expansion valve 26, and then flows upward through one pipe 18 b extending in the vertical direction, and then flows through the refrigerant pipe 18 a fixed to the refrigerant jacket 37. At this time, the heat transfer plate 60 heated by the heat generated by the power element 56a is cooled.

  The refrigerant that has flowed through the refrigerant pipe 18 a flows downward through the other pipe 18 b extending in the vertical direction, is then introduced into the outdoor heat exchanger 25, evaporates, and passes through the four-way switching valve 28 to the accumulator 27. Inflow. The gas refrigerant separated here is sucked into the compressor 23. This refrigerant circulation is continuously performed during the heating operation.

  As described above, in the present embodiment, the refrigerant jacket 37 that is thermally connected to the heat transfer plate 60 and the pair of pipes 18b that can be bent and deformed in a direction to separate the refrigerant jacket 37 from the heat transfer plate 60 are provided. Since the cooling member 100 having the cooling member 100 is provided, the structure of the refrigerant circuit including the cooling member 100 is previously disposed on the bottom plate 30a, and then the electrical component module 35 is disposed at the position where the electrical component module 35 is disposed. Even when the pair of pipes 18 b is employed, the refrigerant jacket 37 can be separated from the position where the electrical component module 35 is to be disposed by bending the pair of pipes 18 b toward the front side, which is the direction away from the heat transfer plate 60. As a result, a large space can be created between the position where the electrical component module 35 is disposed and the refrigerant jacket 37, so that the electrical component module 35 is prevented from colliding with the cooling member 100 and the like. 35 can be safely arranged at the arrangement position.

  In the present embodiment, the electrical component module 35 can be disposed at the disposition position by guiding the first engagement member 71 to the second engagement member 81 and sliding it, so that the predetermined slide movement is possible. The electrical component module 35 can be moved along the path. As a result, when the electrical component module 35 is disposed, the electrical component module 35 can be further prevented from colliding with the cooling member 100 and the like, so the electrical component module 35 is disposed more safely and accurately. can do.

  Further, in this embodiment, since the slide movement direction is a direction from the top to the bottom, the first engagement member 71 is moved to the second engagement member 81 after the electrical component module 35 is placed above the placement position. The electrical component module 35 can be disposed at the disposed position by sliding it from above to below along the vertical portion 83. As a result, the electrical component module 35 can be slid using its own weight, so that the load can be reduced in the case of manual work by an operator, and the power consumption can be reduced in the case of work by a machine. You can save.

  Further, in the present embodiment, since the first engaging member 71 is slid to the back side and the electrical component module 35 is guided to the upper part of the arrangement position, the lateral component 85 is provided. It can be safely and accurately moved from the side to the back side to the upper part of the arrangement position.

  Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the refrigerant jacket 37 as a cooling unit is disposed on the front side of the casing 30 with respect to the power element 56a of the electrical component module 35, and the pair of pipes 18b are configured to be able to bend and deform toward the front side. However, the present invention is not limited to this example. For example, the cooling unit may be disposed at other positions such as the back side and the right side of the casing 30 with respect to the power element 56a. When the cooling unit is disposed on the back side with respect to the power element 56a, the pair of pipes 18b are configured to be able to bend and deform toward the back side, and the cooling unit is disposed on the right side with respect to the power element 56a. In this case, the pair of pipes 18b are configured to bend and deform toward the right side. Further, the machine room and the heat exchange chamber may be provided at opposite positions, the cooling unit may be disposed on the left side with respect to the power element 56a, and the pair of pipes 18b may be configured to bend and deform toward the left side. .

  Moreover, in the said embodiment, although the refrigerant | coolant jacket 37 as a cooling part had two upper and lower grooves extended in a longitudinal direction, although the refrigerant | coolant piping bent in U shape was press-fitted in these groove | channels, It is not limited to this. For example, the refrigerant jacket may have a through-hole, and a pair of pipes may be connected to one end and the other end of the through-hole, respectively.

  Moreover, in the said embodiment, although the case where the vertical part and horizontal part of a 2nd engagement member were separate bodies was illustrated, the vertical part and horizontal part may be comprised by the integral member.

  Moreover, in the said embodiment, although the case where the 2nd engagement member 81 had the vertical part 83 and the horizontal part 85 was illustrated, the 2nd engagement member 81 may be only a vertical part, for example, It may be only part.

  Moreover, although the case where the 2nd engagement member was provided in the partition plate as a support body was illustrated in the said embodiment, it is not limited to this. For example, the second engagement member may be provided on the inner wall surface of the casing, or may be provided on a support other than the partition plate fixed to the casing.

  In the above embodiment, the case where the upper stopper 86 and the rear stopper 88 are integrated with the lateral portion 85 is exemplified. However, these stoppers 86 and 88 are manufactured separately from the lateral portion 85 and are supported by the casing 30 or the support. The structure fixed to the partition plate 39 as a body may be sufficient.

  Moreover, although the said embodiment illustrated the case where a pair of piping 18b had the lower side part 181, the intermediate | middle part 182, and the upper side part 183, it is not limited to this. For example, the pair of pipes 18b may be linear pipes extending from the lower side to the upper side substantially along the vertical direction.
