Description

  The present invention relates to an electrical component module and an outdoor unit including the same.

  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, the electrical component module is disposed after the refrigerant circuit component including the components joined to the heat radiation fins 10a and the refrigerant pipe 20a is assembled on the base of the outdoor unit. In this case, when the electrical component module is inserted into a narrow space between the part 11a of the partition plate and the component where the radiating fin 10a and the refrigerant pipe 20a are joined, the electrical component module collides with the component or the like. Therefore, there is a possibility that the insertion may be hindered, and there may be a problem that it takes time to install the electrical component module.

  Therefore, the present invention has been made in view of the above points, and an object of the present invention is to provide an electrical component module that can be easily mounted in an outdoor unit and an outdoor unit including the same. .

  The electrical component module (35) of the present invention is disposed by being inserted from a predetermined insertion direction at a predetermined position in an outdoor unit of an air conditioner having a refrigerant circuit. The electrical component module (35) has a power element (56a). The electrical component module (35) includes a connection surface (60a) capable of thermally connecting a cooling unit (37) for cooling the power element (56a) with the refrigerant of the refrigerant circuit, and the connection surface (60a). And a guide part (97, 98) for guiding the cooling part (37) to the connection surface (60a) at the time of insertion into the arrangement position. .

  In this configuration, the guide portions (97, 98) are provided in a portion closer to the insertion direction than the connection surface (60a). Therefore, in the case of adopting a manufacturing method in which the constituent of the refrigerant circuit including the cooling unit (37) is previously arranged on the base, and then the electric component module (35) is inserted into a predetermined arrangement position, When the product module (35) is inserted into the arrangement position from the predetermined insertion direction, even if the cooling section (37) is present on the insertion path, the cooling section (37) is the guide section (97). , 98) is appropriately guided to the connection surface (60a) side, so that the insertion of the electrical component module (35) can be prevented from being hindered. Thereby, an electrical component module (35) can be easily attached to a predetermined arrangement | positioning position.

  Further, in the present invention, the connection surface (60a) is provided on a side surface along the insertion direction, and the guide portion (97) extends from an end of the side surface on the insertion direction side to the insertion direction side. It is preferable to have a guide surface (97a) that extends and is inclined or curved toward the back side of the side surface.

  In this configuration, when the electrical component module (35) is inserted into the arrangement position from a predetermined insertion direction, even if the cooling unit (37) exists on the insertion path, the cooling unit (37) After being in contact with the guide surface (97a), it is appropriately guided to the connection surface (60a) side while moving relative to the electrical component module (35) along the guide surface (97a). Thereby, an electrical component module (35) can be easily attached to an arrangement | positioning position. Moreover, since it is the inclined or curved guide surface (97a) that contacts the cooling unit (37) with the electrical component module (35), the impact when the electrical component module (35) contacts the cooling unit (37). Can be reduced. Thereby, an electrical component module (35) can be safely attached to an arrangement | positioning position.

  The guide surface (97a) is inserted into the electrical component module (35) when the length in the direction perpendicular to the connection surface (60a) is larger than the length from the end on the insertion direction side to the back surface. Almost the entire end portion on the direction side is covered by the guide surface (97a). Therefore, even if the cooling unit (37) is displaced from the back side with respect to the electrical component module (35), the cooling unit (37) is inserted into the guide surface (97a) when the electrical component module (35) is inserted. And is guided appropriately to the connection surface (60a) side while moving relative to the electrical component module (35) along the guide surface (97a).

  A cover (46) that covers the connection surface (60a) so as to form a predetermined gap with the connection surface and accommodates the cooling part (37) in the gap is formed on a side surface along the insertion direction. The guide part (98) may be provided at a distal end part on the insertion direction side of the cover (46) so as to guide the cooling part (37) toward the gap.

  In this configuration, even if the connection surface (60a) is covered with the cover (46), the cooling portion (37) is provided by the guide portion (98) provided at the distal end portion on the insertion direction side of the cover (46). ) Can be guided toward the gap and accommodated in the cover (46).

  The cover (46) is opposed to the connection surface (60a) and the opposite surface in the width direction by extending from both sides of the opposite surface in the width direction toward the connection surface (60a). The guide portion (98) is provided at a peripheral edge portion on the insertion direction side of each side surface, and is inclined so as to extend from the peripheral edge portion to the insertion direction side and spread laterally. Or you may have the guide surface (98a) which curves.

  In this configuration, even if the cooling part (37) is arranged to be shifted relative to the gap of the electrical component module (35) in any of the width directions, the electrical component module (35) is inserted. Sometimes, the cooling part (37) abuts on one of the guide surfaces (98a) provided at the peripheral edge portions of the pair of side surfaces, and is relative to the electrical component module (35) along this guide surface (98a). As it moves, it is guided toward the gap and is housed inside the cover (46).

  A pair of support portions (S) that are erected from both sides in the width direction of the connection surface (60a) and support the cover (46) are provided on the side surfaces along the insertion direction, and the guide portions ( 98) are provided at the distal end portions on the insertion direction side of the pair of support portions (S) so as to guide the cooling portion (37) toward the connection surface (60a). You may have the guide surface (98a) which inclines or curves so that it may extend in the insertion direction side and it spreads to the side.

  In this configuration, even if the cooling part (37) is disposed relatively displaced in either of the width directions with respect to the connection surface (60a) of the electrical component module (35), the electrical component module ( 35), the cooling part (37) abuts on one of the guide surfaces (98a) provided at the distal ends of the pair of support parts (S), and along the guide surface (98a), the electrical component is placed. It is guided toward the gap while moving relative to the module (35).

  The outdoor unit of the present invention is used for an air conditioner having a refrigerant circuit.

  The cooling unit (37) is supported by a pair of pipes (18b) provided on the upstream side and the downstream side of the cooling unit (37) in order to send the refrigerant to the cooling unit (37) side. It is preferable that the pair of pipes (18b) can be bent and deformed.

  In this configuration, even when the cooling unit (37) is present on the insertion path of the electrical component module (35), the cooling unit (37) is in contact with the end of the electrical component module (35). The pair of pipes (18b) is bent and deformed by the applied force, and the cooling unit (37) supported by the pipes (18b) is moved along with the bending deformation. Therefore, when the electrical component module (35) is inserted, the cooling portion (37) can be easily moved relative to the electrical component module (35) along the guide portions (97, 98). Guided appropriately to the (60a) side. Moreover, since the cooling part (37) can be relatively moved with the bending deformation of the pair of pipes (18b), the impact when the electrical component module (35) contacts the cooling part (37) is greatly increased. To be reduced. As a result, the electrical component module (35) can be more safely attached to the planned placement 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). The first engaging member (71) is slidable downward, and the electrical component module (35) is directed downward while the guide portions (97, 98) are disposed downward. And a second engagement member (81) for insertion to the installation position.

  In this configuration, when the electrical component module (35) is inserted, the electrical component module (35) is arranged through a slide movement path determined in advance by the first engagement member (71) and the second engagement member (81). Since it is guided to the installation position, the electrical component module (35) can be accurately attached to the planned installation position. Moreover, even if the cooling part (37) contacts the end part of the electrical component module (35), it moves along the guide part (97, 98) by bending deformation, so that it contacts the electrical component module (35). The impact of time is reduced.

  As described above, according to the present invention, since the cooling unit is appropriately guided to the connection surface side by the guide unit, it is possible to prevent the insertion of the electrical component module from being hindered. Thereby, an electrical component module can be easily attached to a predetermined arrangement position.

  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.

The terminal block 46 is provided below the front substrate 55 on the front surface of the main surface portion 51 a of the main member 51. In other words, the coolant jacket 37 is disposed below the front substrate 55. And in this embodiment, the terminal block 46 is comprised so that opening and closing of the space which accommodates the refrigerant | coolant jacket 37 is possible. The solid line in FIG. 8 indicates the terminal block 46 in the open state, and the two-dot chain line indicates the position of the terminal block 46 in the closed state.

  The terminal block 46 has a substantially rectangular front surface portion 46a that covers the front surface side of the refrigerant jacket 37 when closed, and a right side surface portion 46b that is bent from both ends in the width direction of the front surface portion 46a and covers the side of the refrigerant jacket 37. And a left side surface portion 46 c and a lower surface portion 46 d that is bent from the lower end of the front surface portion 46 a and covers the lower side of the refrigerant jacket 37. The right side surface portion 46b and the left side surface portion 46c are respectively attached to a pair of support plates S, S (see FIG. 14A) erected from the main member 51 by bolts B at their upper portions. A terminal connection portion t is attached to the front surface of the front surface portion 46a.

  The terminal block 46 also has a function as a gripping part (second gripping part) of the electrical component module 35. As shown in FIGS. 4 and 8, the terminal block 46 protrudes in a substantially horizontal direction from the holding member 44 to the near side in the open state, and has a hole 48 a at a position on the near side from the terminal connection portion t. ing. The hole 48 a and the periphery thereof become the second grip 48. That is, when the electrical component module 35 is manually attached or removed by the operator, the finger opposite to the one gripping the first grip 43 is inserted into the hole 48a and the hole 48a is inserted. The second grasping portion 48 is grasped so that the front side is grasped by the hand.

  The back protective cover 47 is a resin molded product, and is attached to the main member 51 so as to be positioned on the back side of the main member 51 of the holding member 44 as shown in FIG. The back protective cover 47 covers a part of the main member 51 and a part of the back side substrate 54.

  Next, the mounting structure of the electrical component module 35 will be described in detail.

  As shown in FIGS. 8 to 10, first engaging members 71 are respectively attached to the left side surface portion 51 b of the electrical component module 35 at two locations, upper and lower. In addition, the partition plate 39 is provided with second engagement members 81 that are respectively engaged with the first engagement members 71 at two locations, upper and lower.

The vertical portion 83 is provided. The upper second engaging member 81 has a vertical portion 83 that engages with the upper first engaging member 71 and slides the first engaging member 71 in the vertical direction. A lateral portion 85 for sliding the first engagement member 71 to the back side and the near side is provided.

  As shown in FIGS. 10B and 11, each vertical portion 83 is a plate-like member obtained by pressing a vertically long flat plate. Each vertical portion 83 includes fixing portions 83a and 83b fixed to the partition plate 39 with bolts or the like in a state where both sides are in surface contact with the partition plate 39 along the vertical direction, and the fixing portions 83a and 83b And an engaging portion 83c positioned therebetween.

  The engaging portion 83c has a U-shape with an approximately center in the width direction opened from the upper end to the vicinity of the lower end. That is, the engaging portion 83c has a pair of vertical portions 83d that are separated from each other in the width direction by the opening and extend in the vertical direction, and a horizontal portion 83e that connects the lower ends of the vertical portions 83d and 83d and extends in the horizontal direction. is doing. Further, at the upper ends of the vertical portions 83d and 83d, the corner portions 83h on the opening side are respectively bent outward.

  In addition, as shown in FIG. 11, the engaging portion 83 c is provided separately from the partition plate 39, and the first engaging member 71 is engaged between the pair of vertical portions 83 d and the partition plate 39. Groove portions 83f and 83g into which the portions 71d and 71e can be inserted are formed. These groove portions 83f and 83g serve as passages for the engaging portions 71d and 71e when the first engaging member 71 slides up and down along the vertical portion 83.

  The distance (opening width) between the one vertical portion 83d and the other vertical portion 83d can be inserted through the front leg portion 71b and the rear leg portion 71c of the first engagement member 71, and the engagement portion 71d. It is adjusted so that it may become smaller than the length of the width direction from the edge part of the front side of this to the edge part of the back side of the engaging part 71e.

  With the configuration as described above, the vertical portion 83 supports the first engagement member 71 in a state in which the engagement portions 71d and 71e of the first engagement member 71 are engaged, and the first engagement member 71 can be slid in the vertical direction. Further, the horizontal portion 83e serves as a stopper that locks the first engagement member 71 at a position where the leg portions 71b and 71c of the first engagement member 71 abut.

  As shown in FIG. 10B, the horizontal portion 85 is a member that is disposed above the vertical portion 83 and guides the first engagement member 71 to a relay position between the separation position and the arrangement position. is there. The horizontal portion 85 is a substantially rectangular fixed portion 85a fixed to the partition plate 39 with bolts or the like in a state of surface contact with the partition plate 39, and is bent substantially from the lower end of the fixed portion 85a so as to extend in a substantially horizontal direction. It has a rectangular mounting path 85b and a side wall 85c that is bent from the end in the width direction of the mounting path 85b and extends upward. The height (length in the vertical direction) of the fixed portion 85 a is designed to be slightly larger than the height of the engaging portions 71 d and 71 e of the first engaging member 71.

  The horizontal portion 85 further includes a flat guide wall 85d that further extends from the back side end of the fixed portion 85a to the back side. The fixed portion 85a and the guide wall 85d are provided along the bent surface of the partition plate 39, and the guide wall 85d is inclined to the right side with respect to the fixed portion 85a from the rear end portion of the fixed portion 85a. Has been placed. The disposition position of the guide wall 85d is directly above the upper end portion of the vertical portion 83, and this position is a relay position between the separation position and the disposition position. This relay position is a position where the direction of sliding movement of the first engagement member 71 changes from the horizontal direction to the vertical direction or from the vertical direction to the horizontal direction.

  The second engagement member 81 further includes an upper stopper 86 and a back stopper 88. The upper stopper 86 is bent from the upper end of the guide portion 85d and extends in a substantially horizontal direction, and has a substantially horizontal inner wall surface. The back side stopper 88 is bent from the tip of the guide portion 85d and extends in a substantially horizontal direction, and has a substantially vertical inner wall surface.

  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 contact the front surface 60a of the plate 60 or in the vicinity thereof.

  However, the arrangement position of the refrigerant jacket 37 may deviate from a desired position due to a dimensional variation of parts or the like. In this embodiment, as shown in FIG. 15A, a case will be described in which the arrangement position of the refrigerant jacket 37 is shifted to the back side from a desired position.

  After the refrigerant circuit component is disposed on the bottom plate 30a as described above, the electrical component module 35 is moved from the separation position to the predetermined arrangement position M as shown in FIGS. 13 (a) to 13 (c). Let 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.

  While the electrical component module 35 moves from the relay position to the installation position, the positional relationship between the electrical component module 35 and the cooling member 100 changes as shown in FIGS. FIG. 15A shows a state corresponding to FIG. 13B, that is, a state in which the electrical component module 35 is in the relay position, and FIG. 15B shows the electrical component module 35 in the relay position, the disposition position, and the like. FIG. 15C shows a state where the guide surface 97a is in contact with the upper end of the refrigerant jacket 37, and FIG. 15C shows a state where the electrical component module 35 has moved further downward than the state shown in FIG. FIG. 15 (d) shows a state corresponding to FIG. 13 (c), that is, a state where the electrical component module 35 is located.

  When the electrical component module 35 is in the relay position, the refrigerant jacket 37 of the cooling member 100 exists on the insertion path of the electrical component module 35 (FIG. 15A). The electrical component module 35 is guided from the relay position to the insertion direction D1 side by the first engagement member 71 and the vertical portion 83.

  When the electrical component module 35 moves in the insertion direction D1, the upper end portion of the refrigerant jacket 37 on the insertion path contacts the guide surface 97a of the electrical component module 35 (FIG. 15B).

  In the present embodiment, the electrical component module 35 moves in the insertion direction D1 on a predetermined insertion path determined in advance by the first engagement member 71 and the vertical portion 83, while the cooling member 100 is a pair thereof. The pipe 18b is provided so as to be able to bend and deform. The guide surface 97a is an inclined surface that is inclined toward the front surface side D from the lower side toward the upper side.

  Therefore, when the electrical component module 35 further moves in the insertion direction D1 from the state shown in FIG. 15B, the guide surface 97a presses the refrigerant jacket 37 toward the front side D. Since the pressed refrigerant jacket 37 is supported by the pair of pipes 18b that can be bent and deformed, the refrigerant jacket 37 moves to the front side D together with the bending deformation of the pair of pipes 18b toward the front side D. In this way, the refrigerant jacket 37 moves relative to the electrical component module 35 along the guide surface 97a by moving the electrical component module 35 toward the insertion direction D1, and thus on the front surface 60a side of the heat transfer plate 60. You will be guided toward.

  When such relative movement continues further, the upper end portion of the refrigerant jacket 37 reaches the upper end of the guide surface 97a, that is, the peripheral portion 51d of the main surface portion 51a (FIG. 15C). After the electrical component module 35 has moved to this position, there is no particular obstacle on the insertion path, so that the electrical component module 35 can be smoothly moved to the planned placement position M (FIG. 15 (d)). Then, it moves relative to the electrical component module 35 along the main surface portion 51 a and reaches a position where it contacts 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 with 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 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 first embodiment, the holding member 44 is provided at the distal end portion on the insertion direction side, and guides the refrigerant jacket 37 to the front surface 60a of the heat transfer plate 60 when inserted into the arrangement position. Since the guide portion 97 is provided, the refrigerant jacket 37 is appropriately guided to the front surface 60 a side of the heat transfer plate 60 by the guide portion 97. Thereby, it can suppress that insertion of the electrical component module 35 is prevented, and the electrical component module 35 can be easily attached to a predetermined arrangement | positioning position.

  Moreover, in 1st Embodiment, while the front surface 60a of the heat exchanger plate 60 is provided in the side surface of the holding member 44, while the guide part 97 is extended to the insertion direction D1 side from the peripheral part of the said side surface side in the said front-end | tip part. Since the guide surface 97a is inclined toward the back side of the side surface, the refrigerant jacket 37 is temporarily present on the insertion path when the electrical component module 35 is inserted into the arrangement position from a predetermined insertion direction. Even in this case, after the refrigerant jacket 37 contacts the guide surface 97a, the refrigerant jacket 37 is appropriately guided toward the connection surface 60a while moving relative to the electrical component module 35 along the guide surface 97a. Thereby, the electrical component module 35 can be easily attached to the arrangement position. Moreover, since it is the inclined guide surface 97a that the refrigerant jacket 37 contacts the electrical component module 35, the impact when the electrical component module 35 contacts the refrigerant jacket 37 can be reduced. Thereby, the electrical component module 35 can be safely attached to the arrangement position.

  In the first embodiment, the refrigerant jacket 37 is supported by a pair of pipes 18b provided on the upstream side and the downstream side of the refrigerant jacket 37 in order to send the refrigerant to the refrigerant jacket 37 side. 18b can be bent and deformed. Even if the cooling unit 37 exists on the insertion path of the electrical component module 35, the pair of pipes 18b are bent and deformed by the force applied when the refrigerant jacket 37 contacts the end of the electrical component module 35. The refrigerant jacket 37 supported by these also moves with the bending deformation. Accordingly, when the electrical component module 35 is inserted, the refrigerant jacket 37 can be easily moved relative to the electrical component module 35 along the guide portion 97, so that the coolant jacket 37 is appropriately guided to the front surface 60 a side of the heat transfer plate 60. Is done. In addition, since the refrigerant jacket 37 can be relatively moved with the deformation of the pair of pipes 18b, the impact when the electrical component module 35 contacts the refrigerant jacket 37 is greatly reduced. As a result, the electrical component module 35 can be more safely attached to the planned placement position.

  In the first embodiment, the first engagement member 71 provided in the electrical component module 35 and the partition plate 39 are slidable downward, and the guide portion 97 is provided. And a second engagement member 81 for inserting the electrical component module 35 downward to the arrangement position in a state of being disposed below.
