However, in the above-mentioned Patent Documents 1 to 3, there is no particular reference to atmospheric moisture (hereinafter also referred to as water vapor) that is directly related to the curing of the adhesive used. On the other hand, the curing time of an adhesive that cures with such moisture depends on the amount of water vapor that directly touches the adhesive that is being cured.
Therefore, for example, by inserting a joined body including two members sandwiching an uncured adhesive into a constant temperature and humidity chamber maintained at high humidity, and increasing the amount of water vapor that touches the adhesive, it can be bonded securely. A method of curing the agent is conceivable. However, when this is introduced into an actual manufacturing process, it is necessary to prepare a plurality of constant temperature and humidity chambers having a size corresponding to the dimensions of the joined body, which causes a problem that installation costs and equipment costs are required.

  In the manufacturing method of the joined_body | zygote of this invention, an adhesive agent intervention process and a hardening process are provided. In this curing step, water vapor derived from water arranged apart from the first joint and the like is supplied to the surrounding space around the first joint and the second joint. Therefore, for example, water vapor can be easily supplied to the surrounding space as compared with the case where a device such as a constant temperature and humidity chamber is used. Thereby, this water vapor can be brought into contact with the adhesive interposed between the first joint portion and the second joint portion of the joined body. Therefore, the adhesive can be cured reliably and early.

In addition, as an adhesive agent, what is necessary is just an adhesive agent hardened | cured with the water vapor | steam in air, for example, a silicone type adhesive agent, a urethane resin type adhesive agent, and a reactive hot melt adhesive agent are mentioned. Moreover, the silicone type sealing agent for FIGP used as a liquid gasket which adhere | attaches a some member and maintains the airtightness of a junction part is also mentioned.
Further, as an example of the combination of the first member and the second member, an oil pan and a cylinder block, an engine valve cover and a cylinder block, a heat radiating member that cools an electronic device using a refrigerant, and a flow that can circulate the refrigerant together with the heat radiating member The flow path forming member which comprises a path | route is mentioned.

Moreover, as a method of supplying water vapor to the surrounding space of the first joint and the second joint, for example, the joined body and water are arranged in the same closed space, and water vapor is supplied to the entire closed space.

Furthermore, as a technique for retaining water, a technique for storing in a container such as a dish, a technique for containing water in a cloth, a fiber aggregate such as absorbent cotton, a technique for including water in a sponge, and the like can be given. It is more preferable to use a shallow container such as a dish or a bat that can take a large opening and water surface so that much water evaporates.
Further, the position of the water to be spaced apart may be a position where water vapor generated from the water is supplied to the surrounding space. However, in order to prevent the retained water from being accidentally applied to the joined body or the first and second joined portions, it is preferable to retain water below the joined body or the first and second joined portions.

  In the method for manufacturing a joined body of the present invention, the uncured joined body and the water holding tool are placed on a carriage to perform a curing process. Therefore, unlike equipment that is difficult to move, such as a constant temperature and humidity chamber, the curing process is generally performed by moving it to an appropriate place with a carriage, and the curing process is advanced during the movement to the next process. The uncured joined body in the process and the water holding tool can be easily handled. Examples of the water holding tool include a container such as a dish, a cloth, a fiber assembly, and a sponge that can hold water.

  Furthermore, in the above method for manufacturing a joined body, the first member is a heat radiating member that cools an electronic device that generates heat by driving, and the second member is joined to the heat radiating member by the heat radiating member. Manufacturing method for forming a liquid gasket made of the adhesive between the first joint portion and the second joint portion. And good.

  According to the method for manufacturing a joined body of the present invention, it is possible to easily and quickly obtain a joined body having a surely cured liquid gasket between the heat dissipation member and the flow path forming member in the adhesive intervening step and the effect step. be able to.

In this gasket curing step, water vapor can be introduced into the internal space through the communication hole and brought into contact with the uncured adhesive, so that the adhesive can be cured reliably and quickly.
Also, by manipulating the amount (humidity) of water vapor to be introduced into the internal space, it is left indoors with uncured adhesive interposed between the first joint and the second joint, Compared with the case where the adhesive is cured, the curing conditions of the adhesive are easily uniform. Therefore, it is easy to align the characteristics of the formed liquid gasket. Thus, a joined body in which a highly reliable liquid gasket is formed can be easily manufactured.

  Furthermore, in the above-described method for manufacturing a joined body, the first member and the second member have a configuration in which two or more communication holes communicating with the internal space are formed, and the gasket curing step includes the communication Among the holes, a bonded body that introduces water vapor into one of the internal spaces from one or more communication holes and discharges the water vapor from one or more other communication holes while curing the adhesive. A manufacturing method is preferable.

(Embodiment 1)
First, Embodiment 1 of the present invention will be described with reference to FIGS.
The joined body according to the first embodiment is an inverter case 10 in which an inverter package module (hereinafter also referred to as IPM) 20 including an electronic element 21 constituting a power transistor or the like is arranged on the upper surface.

1 and 2 show an inverter device 1 including an inverter case 10 according to the first embodiment and an IPM 20.
Among these, in the IPM 20, the power element 21, the solder layer 22, the conductor pattern 24, and the insulating plate 25 are stacked and fixed in order from the top. Further, a bonding wire 29, bus bars 27 and 28, a housing 26, and the like are arranged around the periphery. The housing 26 is fixed to the upper surface 11u of the case cover 11 (described later) of the inverter case 10 with an adhesive BN. On the other hand, the power element 21, the bonding wire 29, and the like are sealed with a silicone gel SG.
Among these, the power element 21 is a heating element such as a power transistor that generates heat when driven, and is attached to a conductor pattern 24 attached on the insulating plate 25 via a solder layer 22. The insulating plate 25 is attached to the upper surface 11 u of the case cover 11 (described later) of the inverter case 10 via the solder layer 23.

On the other hand, the inverter case 10 includes a case cover 11 made of a Cu—Mo material, which is a material with good thermal conductivity, and a rectangular box-shaped case main body 12 having an open top. And the case cover 11 and the case main body 12 are joined via the liquid gasket 13 (refer FIG. 2). Specifically, a cover peripheral edge portion 11 </ b> A that is a peripheral edge portion of the case cover 11 and a main body opening end portion 12 </ b> A that forms an opening of the case main body 12 are in contact with the liquid gasket 13. Further, the case cover 11 and the case main body 12 are fastened by a plurality of bolts 19.
Among these, the case main body 12 includes a cylindrical water supply port 12H1 and a water discharge port 12H2 that pass through the case body 12 in the vicinity of the center of the two side wall portions 12m and 12n that are parallel to each other. Through the water supply port 12H1 and the drainage port 12H2, the cooling water LC is circulated through the cooling water channel WR inside the inverter case 10 surrounded by the case cover 11 and the case main body 12 joined through the liquid gasket 13 (FIG. 2). reference). Thereby, in the cooling water channel WR, the liquid-tight cooling water LC can take the heat of the power element 21 through the case cover 11, and thus the temperature rise of the power element 21 is suppressed.

Next, a method for manufacturing the inverter case 10 will be described with reference to FIGS.
FIG. 3 shows a perspective view of the case body 12 before joining. Of the above-described main body opening end portion 12 </ b> A, an opening end surface 12 g surrounding the opening of the case main body 12 is a square ring-shaped plane that borders the opening of the case main body 12. A plurality of bolt holes 12x used for fastening with the case cover 11 are formed in the main body opening end 12A.

  Next, the adhesive intervening step will be described with reference to FIG. The case main body 12 is a BB cross-sectional view of the case main body 12 shown in FIG. First, an uncured liquid gasket 13 made of a black paste-like silicone adhesive (viscosity: 200 Pa · s) is applied to the opening end face 12g of the main body opening end 12A of the case body 12 (FIG. 4 ( a)). At this time, the uncured liquid gasket 13b is applied in a single annular shape along the center line 12gc (see FIG. 3) on the opening end face 12g. In addition, in the vicinity of the bolt hole 12x, it is applied to the cooling water channel WR side to be described later in the opening end face 12g. The case body 11 is covered with the case body 12 from the upper side (upper side in the drawing). At this time, the position of the bolt hole 12x in the opening end surface 12g and the position of the bolt through hole 11x formed in the case cover 11 are matched. Thereby, the uncured liquid gasket 13 b comes into contact with the cover peripheral edge portion 11 </ b> A of the case cover 11. The uncured liquid gasket 13b applied in the vicinity of the bolt hole 12x spreads around the bolt 19 (bolt hole 12x) and comes into contact with the cover peripheral portion 11A. Thereafter, the case cover 11 and the case main body 12 are fastened with a plurality of bolts 19, and the uncured liquid gasket 13b, the cover peripheral edge portion 11A, and the main body opening end portion 12A are brought into close contact with each other (see FIG. 4B). . Hereinafter, the case cover 11 and the case main body 12 in a state where the uncured liquid gasket 12b is interposed are referred to as an uncured inverter case 10b.

Next, the curing step will be described with reference to FIGS. In the first embodiment, the uncured inverter case 10b described above is fixed by a lifting jig 50 (see FIG. 5A). Specifically, the lifting jig 50 includes two arm portions 52 that extend vertically from the pedestal portion 51, and a distal end portion 52 </ b> A of each arm portion 52 includes a rectangular plate-shaped holding portion 53. . The holding portion 53 is in close contact with the side wall surfaces 12s and 12t of the case body 12, and holds the uncured inverter case 10b. Note that a space is provided between the uncured inverter case 10 b and the pedestal 51.
In this way, the uncured inverter case 10 b sandwiched and fixed to the lifting jig 50 is placed on the carriage 40. The carriage 40 has a table plate 41 that is cantilevered and installed horizontally. In addition, the upper side of the cart 40 above the table plate 41 is covered with a shielding cover 45 made of a flexible resin sheet that does not transmit moisture (water vapor) in the atmosphere. One surface of the shielding cover 45 is an openable / closable cover portion 45A. In addition, the carriage 40 has a plurality of wheels 47, which makes the carriage 40 easily movable. Further, the carriage 40 has a shelf portion 48 r that protrudes horizontally inside a leg portion 48 at the top of the wheel 47.

  For this reason, the uncured inverter case 10b can be placed on the carriage 40 together with the lifting jig 50 holding the inverter case 10b. Specifically, the table plate 41 of the carriage 40 enters the space between the uncured inverter case 10b and the pedestal portion 51 from the side wall portion 12n side of the case body 12 with the open / close cover portion 45A raised. Next, the carriage 40 is moved. The end 51e of the pedestal 51 in the lifting jig 50 is placed on the shelf 48r. Thus, the lifting jig 50 that holds the uncured inverter case 10 b is placed on the carriage 40. Thereafter, the open / close cover part 45A that has been opened is closed, and the entire area above the table plate 41 is covered with the shielding cover 45 (see FIG. 6).

FIG. 7 shows a cross-sectional view of the carriage 40 in a state where the uncured inverter case 10b is placed. A bat 49 storing water LW is placed on the table plate 41 of the carriage 40. Then, the uncured inverter case 10b is covered by the above-described shielding cover 45 including the upper and surrounding spaces except for the bottom side. Assuming that the space covered by the shielding cover 45 is the shielding space WS, a part of the water LW held by the bat 49 of the table plate 41 is changed into the water vapor GW and enters the shielding space WS while rising. As a result, the steam GW rising from the table plate 41 is supplied to the entire uncured inverter case 10b in the shielded space WS. The steam GW is also supplied to the surrounding space IS1 around the cover peripheral edge portion 11A and the main body opening end portion 12A through the uncured liquid gasket 13b in the shielding space WS. On the other hand, the water vapor GW is also supplied to the cooling water channel WR located inside the uncured inverter case 10b through the water supply port 12H1 and the drain port 12H2. Then, the steam GW is also supplied to the peripheral space IS2 around the cover peripheral edge portion 11A and the main body opening end portion 12A through the uncured liquid gasket 13b in the cooling water channel WR.
Thereby, since many water vapor | steam GW contacts the uncured liquid gasket 13b, the uncured liquid gasket 13b hardens | cures reliably and early. Thus, the inverter case 10 provided with the hardened liquid gasket 13 is completed.
Thereafter, the housing 26 including the IPM 20 and the bus bars 27 and 28 is fixed to the upper surface 11u of the case cover 11 by thermocompression bonding via the solder layer 25 and the adhesive BN, respectively. Furthermore, each part is connected with the bonding wire 29, silicone gel SG is inject | poured into the space of the center part of the housing 26, and it heat-hardens it. Thus, the inverter device 1 is completed (see FIG. 1).

  The manufacturing method of the inverter case 10 according to the first embodiment includes the above-described adhesive intervening step and the curing step. In this curing step, the cover rim 11A and the main body are separated from the cover peripheral portion 11A and the main body opening end portion 12A, specifically, the water vapor GW derived from the water LW disposed below the uncured inverter case 10b. This is supplied to the surrounding spaces IS1, IS2 around the opening end 12A. Therefore, for example, the steam GW can be easily supplied to the surrounding spaces IS1 and IS2 as compared with a case where a device such as a constant temperature and humidity chamber is used. Further, this allows the water vapor GW to be brought into contact with the uncured liquid gasket 13b interposed between the cover peripheral edge portion 11A and the main body opening end portion 12A of the uncured inverter case 10b. Therefore, the uncured liquid gasket 13b can be cured reliably and early.

  Further, in the manufacturing method of the inverter case 10 of the first embodiment, in the curing step, the surrounding spaces IS1 and IS2 around the cover peripheral edge portion 11A and the main body opening end portion 12A are covered with the shielding cover 45, and the surrounding space around this is covered. Increase the humidity of IS1 and IS2. Accordingly, the water vapor GW from the water LW is more reliably supplied to the peripheral spaces IS1 and IS2 around the cover peripheral edge portion 11A and the main body opening end portion 12A, and the uncured liquid gasket 13b is cured more reliably and quickly. be able to.

Further, the uncured inverter case 10b and the butt 49 are placed on the carriage 40 to perform the curing process. Therefore, unlike equipment that is difficult to move, such as a constant temperature and humidity chamber, it is generally time consuming to move the curing process by moving the carriage 40 to an appropriate place, or to advance the curing process while moving to the next process. The uncured inverter case 10b and the bat 49 holding water during the curing process can be easily handled.
Thus, the inverter case 10 having the liquid gasket 13 that is securely cured between the case cover 11 and the case main body 12 can be manufactured easily and quickly.

  In addition, the inverter case 10 of the first embodiment is a bonded body, the uncured inverter case 10b is an uncured bonded body, the case cover 11 is a first member and a heat radiating member, and the case body 12 is a second member and a flow passage. It corresponds to each member. Further, the cover peripheral edge portion 11A is the first joint portion, the main body opening end portion 12A is the second joint portion, the liquid gasket 13 is the adhesive, the cooling water passage WR is the flow passage, the IPM 20 is the electronic device, and the shielding cover 45. Corresponds to the cover member, and the bat 49 corresponds to the water holder.

Therefore, different points will be mainly described, and description of similar parts will be omitted or simplified, but similar functions and effects will occur for similar parts. In addition, the same contents are described with the same numbers.

  The method for manufacturing the inverter case 110 includes an adhesive intervening step and a gasket curing step. Among these, the adhesive intervening step is the same as that in the first embodiment, and thus the description thereof is omitted (see FIG. 4).

In the gasket curing step, the steam GW is supplied to the cooling water passage WR from the water supply port 12H1 of the uncured inverter case 10b formed in the adhesive intervening step (see FIG. 8). Specifically, rubber hoses 61 and 62 are connected to the water supply port 12H1 and the drainage port 12H2 of the uncured inverter case 10b, respectively. Then, the steam GW is fed into the cooling water passage WR of the uncured inverter case 10b through the hose 61 connected to the water supply port 12H1. On the other hand, the water vapor GW in the cooling water channel WR is discharged from the hose 60e connected to the drain port 12H2. Thereby, the inside of the cooling water channel WR of the uncured inverter case 10b is kept at a constant high humidity.
The uncured liquid gasket 13b of the uncured inverter case 10b comes into contact with the water vapor GW introduced into the cooling water channel WR and is cured. Specifically, the water vapor GW supplied to the cooling water channel WR (or the above-described surrounding space IS2) comes into contact with the uncured liquid gasket 13b at the cover peripheral edge portion 11A and the main body opening end portion 12A, thereby uncured. The liquid gasket 13b is cured. Thus, the inverter case 110 including the cured liquid gasket 13 is completed.

The manufacturing method of the inverter case 110 according to the second embodiment includes the above-described adhesive intervening step and the gasket curing step. In this gasket curing step, since the water vapor GW can be introduced into the cooling water channel WR through the water supply port 12H1 and brought into contact with the uncured liquid gasket 13b, the liquid gasket 13b can be reliably and quickly cured.
Further, by manipulating the amount (humidity) of the water vapor GW introduced into the cooling water channel WR, it is left in the room with the uncured liquid gasket 13b interposed between the cover peripheral edge portion 11A and the main body opening end portion 12A. Compared with the case where the uncured liquid gasket 13b is cured with the water vapor therein, the curing conditions of the liquid gasket 13b are easily uniformed. Accordingly, it is easy to align the characteristics of the formed liquid gasket 13. Thus, the inverter case 110 formed with the highly reliable liquid gasket 13 can be easily manufactured.
Furthermore, in the manufacturing method of the inverter case 110 according to the second embodiment, the case body 12 configures the water supply port 12H1 and the drain port 12H2. Then, the water vapor GW is introduced into the cooling water channel WR from the water supply port 12H1, while the water vapor GW is discharged to the outside from the drain port 12H2. Thereby, it is easy to control the humidity in the cooling water channel WR appropriately.
From the above, the inverter case 110 having the securely cured liquid gasket 13 between the case cover 11 and the case body 12 can be easily and quickly manufactured.
In addition, the inverter case 110 of the second embodiment corresponds to the joined body, and the cooling water passage WR corresponds to the internal space.
