[0003] The present invention further relates to a method for filling a hollow space. [Background technology]

[0004] Component systems are known in the prior art, including components and a filling device for filling a hollow space formed between the interconnected components. The hollow space to be filled may be, for example, a gap between a heat sink and a printed circuit board, which can or should often be filled with a thermally conductive, viscous filling material, such as a high-viscosity thermal paste, to improve heat conduction between the two components. Injecting a highly viscous liquid into a narrow hollow space requires a high injection pressure, which means that a supply element, such as an injection nozzle, that introduces the highly viscous liquid into the hollow space must be mechanically fixed in place at the supply opening of the hollow space. This fixation must withstand pressure acting in the direction opposite to the filling direction. [Prior art documents] [Patent documents]

[0006] Known mechanical position fixing (e.g. screw cap with seal) disadvantageously requires a complex mounting operation of the dispensing element in the dispensing opening, thus increasing the filling time and effort, and often requires additional surrounding mechanical locking means.

[0011] According to the present invention, the closure sealing element is configured as an elastically expandable (expandable, enlargeable) body that is configured to switch between a closed position and an open position, wherein the closure sealing element is in the open position during insertion of the supply element into the supply section through the supply opening and can be switched to the closed position when the supply element reaches the filling position in the supply section, wherein in the closed position, the outer surface of the closure sealing element that defines the closure sealing element is in sealing contact with the edge surface of the supply section that defines the supply section, and this contact prevents movement of the supply element in a direction opposite to the insertion direction of the supply element, and wherein, after the filling process, the closure sealing element can be switched from the closed position to an open position, wherein in the open position, the outer surface of the closure sealing element is substantially not in contact with the edge surface of the supply section, so that after the filling process, the closure sealing element can be removed from the supply opening and the supply element can be removed from the supply section through the supply opening in a direction opposite to the insertion direction.

[0012] This has the advantage that the closure sealing element (whose closed position can also be referred to as the closed state; its released position can likewise be referred to as the released state) can be introduced into the supply opening before filling, acts in a closing and sealing manner on the supply opening (or the supply part) during filling, and can be removed from the supply opening after filling, particularly without the need for additional fixing or sealing means. The (temporary) sealing of the supply opening and the locking / fixing of the supply element in the direction opposite to the insertion direction can be achieved particularly by a sufficiently high adhesive contact between the outer surface of the closure sealing element (particularly maximally enlarged in the closed state) and the edge surface of the supply part. In the released position, this adhesive contact can be released again, so that the closure sealing element is separated from the edge surface of the supply part. The closure sealing element can be designed as a round object that can be elastically expanded in the radial direction.

The (temporary) sealing of the supply opening and the locking / fixing of the supply element in the direction opposite to the insertion direction can be achieved in particular by a sufficiently high adhesive contact or frictional bond between the outer shell surface of the closure sealing element (which is particularly maximally enlarged in the closed state) and the inner surface of the inlet channel. In the released position, this adhesive contact can be released again, so that the closure sealing element is moved away from the inner surface of the inlet channel. Preferably, the enlarged portion of the elastomeric cylinder body along the insertion direction is substantially the same length as the length of the inlet channel along the insertion direction.

[Figure 5] FIG. 5 is a top view of the component components of the component system of FIG. 4. [Figure 6] FIG. 5 shows a perspective view of the component system of FIG. 4 with the filling device in a closed position. [Example]

[0030] 1 shows a cross-sectional view of a first embodiment of a component system 1 according to the invention, which comprises at least two, in particular connected, components 2a, 2b, between which a hollow space 3 to be filled is formed. The hollow space 3 has a feed portion 3a which leads to a feed opening 3a1 formed in the component 2a. The feed portion 3a leads substantially into the hollow space 3. The feed portion 3a is configured as a cylindrical inlet channel having a longitudinal extent along the insertion direction z.

[0031] Figures 2a and 2b show a detailed view of the first component 2a.

[0032] The component system 1 further includes a filling device 4 for filling the hollow space 3 during a filling process, during which a filling material, in particular a viscous liquid, can be or is filled into the hollow space 3. The filling device 4 is only diagrammatically illustrated in FIG. 1 . In the filled state after the filling process, the filling material substantially completely fills the hollow space 3, so that the at least two components 2 a, 2 b are in contact with each other at least partially via the filling material. The filling material may in particular comprise a viscous thermally conductive material and / or a viscous adhesive. The filling material may comprise a thermal interface material (TIM), which forms a thermal contact between the at least two components 2 a, 2 b. The filling material is preferably configured to harden after the filling process.

[0033] The filling device 4 has a supply element 4a for filling the hollow space 3 with filling material. The supply element 4a is configured to be inserted at least partially into the supply portion 3a of the hollow space 3 along the insertion direction z through a supply opening 3a1 before the filling process. In the inserted state, an injection opening 5 of the supply element 4a protrudes into the supply portion 3a. During the filling process, the filling material can be introduced from the filling device 4 through the supply portion 3a into the hollow space 3 via the injection opening 5. The supply element 4a includes a supply channel 6 having a longitudinal extension L along the insertion direction z, through which the filling material can be guided, and at its outlet (distal) end the injection opening 5 is configured. The supply channel 6 has a wall 6a that defines the supply channel 6, with a closing sealing element 4b configured on a particularly elastic portion of the wall 6a.

[0034] To hold the feed element 4a in position and seal the feed opening 3a1 during filling, the feed element 4a has a closure sealing element 4b, which is configured to close and seal the feed section 3a of the hollow space 3 in the closed position during the filling process. The closure sealing element 4b ensures that the protruding part of the feed element 4a into the feed section 3a is prevented (secured) therein against being pushed out of the feed opening 3a1 by the filling pressure present during filling and acting against the insertion direction z.

[0035] Furthermore, the closure sealing element 4b is configured to seal the feed opening 3a1 during the filling process, and in the open position, the closure sealing element 4b is configured to allow the feed element 4a to be inserted into the feed portion 3a via the feed opening 3a1 before the filling process and to be removed from the feed portion 3a via the feed opening 3a1 after the filling process.

[0036] In the embodiment shown in Figure 1, the closure sealing element 4b can be configured as an elastically expandable (spherical) body (see Figures 2a-2c in detail) or as a bayonet-actuable ball-joint-like element (see Figures 4-6 in detail), which body or element is configured to switch between a closed position and an open position. The "elastically expandable body" embodiment is described in more detail below. The "bayonet embodiment" is described in more detail in the following paragraphs in conjunction with Figures 4-6.

[0037] The closure sealing element 4b is in the release position during insertion of the supply element 4a into the supply part 3a through the supply opening 3a1. This state is shown in Figure 2a. In the embodiment according to Figures 1 to 2c, the closure sealing element 4b is configured as an elastomeric body, which has a substantially spherical shape in the closed position and a substantially cylindrical shape in the release position. Preferably, the supply opening 3a1 has an opening shape in its main cross section oriented perpendicular to the insertion direction z, which opening shape corresponds to the cross-sectional shape of the supply element 4a and the closure sealing element 4b in the main cross section in the release position.

[0038] The closure sealing element 4b can be moved to a closed position (e.g., by pumping air into it using an air pump or similar device) when the supply element 4a reaches a filling position within the supply part 3a. In the closed position, the closure sealing element 4b expands so that the outer surface of the closure sealing element 4b that defines it comes into sealing contact with the edge surface 3b of the supply part 3a that defines it, preventing movement of the supply element 4a in a direction opposite to the insertion direction of the supply element 4a. This state is shown in Figure 2b.

[0039] After the filling process, the closure sealing element 4b can be transferred from the closed position to the open position (e.g., by extracting air using a device such as an air pump). In the open position, the outer surface of the closure sealing element 4b is substantially out of contact with the edge surface 3b of the supply part 3a, so that after the filling process, the closure sealing element 4b can be removed from the supply opening 3a1 and the supply element 4a can be removed from the supply part 3a via the supply opening 3a1 in the direction opposite to the insertion direction z.

[0040] In the embodiment according to Figures 1 to 2c, the closing sealing element 4b is configured integrally with the supply element 4a, in particular in the form of a balloon catheter, preferably in the form of a balloon catheter, which is substantially spherical in the closed position and substantially cylindrical in the open position.

[0041] In the embodiment according to FIG. 2c, the feed section 3a is formed in the shape of a cone of revolution along its longitudinal extent, with a cone radius that increases along the insertion direction z.

[0042] 3a and 3b show a second embodiment of the closure sealing element 4b. In this embodiment, the closure sealing element 4b is configured as an expandable elastomeric cylindrical body. In the open position, the elastomeric cylindrical body has a first cylindrical radius and in the closed position, a second cylindrical radius. The first cylindrical radius is smaller than the second cylindrical radius. The supply part 3a is configured as an inlet channel having a longitudinal extension along the insertion direction z. The inlet channel is cylindrical along its longitudinal extension and has an inlet channel radius that is substantially equal to or smaller than the second cylindrical radius of the closure sealing element 4b. Due to the variable (or expandable or contractible (e.g., by pumping or extracting air using an air pump)) radius, in the closed position during filling of the hollow space 3, the outer shell surface of the expanded elastomeric cylindrical body is in sealing contact with the inner inlet channel surface defining the inlet channel and is in sealing contact with the supply opening 3a1. This contact results in a pressing force acting radially from the enlarged outer shell surface onto the inner surface of the inlet passage, whereby movement of the supply element 4a in a direction opposite to the insertion direction of the supply element 4a is prevented, particularly by the adhesive engagement contact, and the supply opening 3a1 is hermetically closed against fluid outflow.

[0043] The elastomeric cylinder body is preferably constructed integrally with the supply element 4a, and the injection opening 5 can be arranged at the outlet (distal) end of the elastomeric cylinder body. The elastomeric cylinder body has a filling channel through which the filling material can be conveyed into the hollow space 3 during filling of the hollow space 3, the expandable part of the elastomeric cylinder body surrounding the filling channel.

[0044] 4 to 6 show a third embodiment of a closure sealing element 40b. Here too, the component system comprises at least two, in particular connected, components 2a, 2b, between which a hollow space 3 to be filled is formed (see also FIG. 1). The hollow space 3 has a feed portion 3a, which leads to a feed opening 3a1 formed in the component 2a.

[0045] The component system likewise comprises a filling device 4 for filling the hollow space 3 during a filling process, during which a filling material, in particular a viscous liquid, can be filled into the hollow space 3 .

[0046] The filling device 4 has a feed element 4a for filling the hollow space 3 with filling material, which is configured to be inserted at least partially along the insertion direction z into the feed portion 3a of the hollow space 3 through a feed opening 3a1 before the filling process, so that an injection opening 5 of the feed element 4a protrudes into the feed portion 3a. During the filling process, the filling material can be introduced from the filling device 4 through the feed portion 3a into the hollow space 3 via the injection opening 5.

[0047] The supply element 4a has a closure sealing element 40b, which is configured to close and seal the supply portion 3a of the hollow space 3 in the closed position during the filling process, so that the protruding portion of the supply element 4a into the supply portion 3a is prevented from being pushed out of the supply opening 3a1 therein by the filling pressure that is present during filling and acts against the insertion direction z. Furthermore, in the closed position, the supply opening 3a1 is sealed. In the open position, the closure sealing element 40b is configured to allow the supply element 4a to be inserted into the supply portion 3a via the supply opening 3a1 before the filling process and to be removed from the supply portion 3a via the supply opening 3a1 after the filling process.

[0048] The closure sealing element 40b has a shape corresponding to the feed portion 3a to form a two-stage bayonet closure mechanism that, together with the feed portion 3a, forms a closed position. To form the first stage of the two-stage bayonet closure mechanism, the closure sealing element 40b is insertable into the feed portion 3a through the feed opening 3a1 along the insertion direction z and, in the inserted state, rotatable about a first axis z1 oriented parallel to the insertion direction z. This rotation of the closure sealing element 40b about the first axis z1 by at least 45°, preferably substantially 90°, establishes first contact between a first edge portion of the feed portion 3a that defines the feed portion 3a and a first contact portion of the closure sealing element 40b. This first contact prevents movement of the closure sealing element 40b in a direction opposite to the insertion direction z.

[0049] To form the second stage of the two-stage bayonet closure mechanism, the closure sealing element 40b can be pivoted about a second axis x perpendicular to the first axis z1. The pivot point is located substantially at the center of the closure sealing element 40b. By pivoting the closure sealing element 40b about the second axis x by at least 30°, preferably substantially 45°, a second contact can be established between a second edge portion of the dispensing portion 3a and a second contact portion of the closure sealing element 40b. This second contact ensures that the dispensing opening 3a1 is sealed by the closure sealing element 40b, particularly during filling of the hollow space 3 with the filler material.

[0050] After filling of the hollow space 3, the second contact can be released by a reverse rotation about the second axis x and the first contact can be released by a reverse rotation about the first axis z1 in order to move the closure sealing element 40b into the release position.

[0051] As can be seen in Figure 5, the closure sealing element 40b is configured as a sphere with two diametrically flattened spherical surface sections, the dispensing opening 3a1 having a complementary shape.

[0052] As can be seen in FIG. 6, the closure sealing element 40b is disposed at the outlet (distal) end portion of the supply element 4a, which has the inlet opening 5 therein.

[0053] The supply element 4a is configured as a supply channel, which has a closing sealing element 40b at its outlet (distal) end. The closing sealing element 40b has a guide portion connected to the supply channel in a fluid-guiding manner, so that the filling material can flow from the supply channel into the guide portion of the closing sealing element 40b, the outlet (distal) end of which has an injection opening 5.
