Description

Air cooling module, server and functional module dismounting method

Technical Field

The present disclosure relates to the field of servers, and in particular, to an air cooling module, a server, and a method for disassembling and assembling a functional module.

Background

The function modules of the current 2U server all use 40 fans (such as 4028 fans, fans with the size of 40×40×28 mm). The 2U server is correspondingly provided with two functional modules, the two functional modules correspond to a group of 40 fans, and when the functional modules are required to be hot plugged, the functional modules and the 40 fans corresponding to the functional modules are directly plugged together. The fan and the functional module are in one-to-one correspondence, and although the fan and the functional module are convenient to be hot plugged, the fan is limited by the size of the fan, so that the heat dissipation effect of the fan is not ideal, and the power consumption of the fan is high. Some fan power consumption may even account for more than 25% of the overall power consumption of the server.

When an 80 fan (e.g., an 8038 fan, a fan with a size of 80×80×38 mm) is used on a 2U server, the entire fan needs to be removed before the functional module is hot plugged, so as to expose the functional module. The hot plug process of the functional module is very tedious and can easily cause rapid abrasion of the connection position of the fan.

Disclosure of Invention

The application provides an air cooling module, a server and a functional module dismounting method, which are convenient for the server to radiate by using a large-size fan.

A first aspect of embodiments of the present application provides an air-cooled module for mounting a fan to a housing having a functional module, the air-cooled module including a rail and a plenum. The guide rail is used for being matched with the shell in a sliding mode, and the guide rail can slide along a first direction relative to the shell. The ventilation part comprises a frame body, the frame body is slidably connected with the guide rail along a second direction, the second direction is perpendicular to the first direction, and the frame body is provided with a ventilation cavity for accommodating a fan.

After the ventilation part is far away from the shell in the first direction through the guide rail, the ventilation part can also slide in the second direction on the guide rail, so that the functional module in the shell is exposed from a gap after the ventilation part slides in the second direction, and the functional module in the shell is taken out conveniently. When the air cooling module is applied to a server, a plurality of functional modules can be simultaneously corresponding to a larger fan, and the fan does not need to be taken down during replacement, so that the hot plug of the functional modules in the server is convenient.

The frame body comprises a main body and a first sliding rail, and the guide rail is provided with a second sliding rail extending along a second direction. A ventilation cavity is arranged in the main body, and the first sliding rail is connected with the main body. The first sliding rail is in sliding fit with the second sliding rail.

The air cooling module realizes the sliding connection of the ventilation part and the guide rail through the first slide rail and the second slide rail, and the first slide rail and the second slide rail can play a role in guiding the movement direction of the ventilation part relative to the guide rail.

The support body includes first baffle and the second baffle that sets up along the second direction interval, and the fan clamp is located between first baffle and the second baffle.

The air cooling module limits the movement of the fan in the second direction through the first baffle plate and the second baffle plate, so that the fan is stable in position in the second direction when the air cooling module is connected with the shell.

A second aspect of embodiments of the present application provides an air cooling module for mounting a fan to a housing having a functional module, including a rail and a ventilation portion. The guide rail is used for being matched with the shell in a sliding way along a first direction. The ventilation portion includes support body and fan, and the support body sets up in the one end of guide rail along first direction, and support body and guide rail are connected along second direction slidable, and second direction perpendicular to first direction, the support body have along the ventilation chamber that first direction link up, and the fan sets up in the ventilation intracavity.

After the ventilation part is far away from the shell in the first direction through the guide rail, the ventilation part can also slide in the second direction on the guide rail, so that the functional module in the shell is exposed from a gap after the ventilation part slides in the second direction, and the functional module in the shell is taken out conveniently. When the air cooling module is applied to a server, a larger fan can be configured and simultaneously corresponds to a plurality of functional modules, and the fan does not need to be taken down during replacement, so that the hot plug of the functional modules in the server is facilitated.

A third aspect of embodiments of the present application provides a server, including an air cooling module as in any implementation form of the first aspect, and further including a housing. The housing has a mounting cavity therein, the mounting cavity including a first subchamber and a second subchamber juxtaposed in a second direction, the first subchamber having a first opening for inserting the functional module in the first direction, the second subchamber having a second opening for inserting the functional module in the first direction. The guide rail is in sliding fit with the housing along a first direction. The ventilation part can simultaneously shade the first opening and the second opening, and thereby simultaneously ventilate the first sub-cavity and the second sub-cavity through the first opening and the second opening. The ventilation part is slidable to a first position and a second position along a second direction relative to the guide rail. When the ventilation part is located at the first position relative to the guide rail, the second opening is opened. When the ventilation part is located at the second position relative to the guide rail, the first opening is opened.

The server supplies air to the first sub-cavity and the second sub-cavity through the fan of the air cooling module at the same time, so that the fan has larger size compared with the fan for supplying air to the first sub-cavity or the second sub-cavity independently. The larger size means larger power and larger air quantity, so that the functional module in the shell has better heat dissipation effect. The ventilation part in the air-cooled module slides along the second direction relative to the guide rail, so that the ventilation part can be slid to the first position when the functional module needs to be taken out from the second sub-cavity, and the ventilation part can be slid to the second position when the functional module needs to be taken out from the first sub-cavity.

Based on the third aspect, in one possible implementation manner, the air cooling module further includes a stop portion, and the stop portion is connected with the guide rail and/or the ventilation portion. The stop portion is used for limiting the sliding of the frame body relative to the guide rail between a first position and a second position.

The server can limit the movement range of the ventilation part relative to the guide rail between the first position and the second position through the stop part, and the probability that the ventilation part is separated from the guide rail is reduced.

Based on the third aspect, in one possible implementation manner, the stop portion includes a first stop block and a second stop block. The first stop block and the second stop block are connected to the frame body at intervals along the second direction.

The server limits the movement interval of the ventilation part relative to the guide rail between the first position and the second position by stopping the movement of the ventilation part in the second direction by the first stop block and the second stop block.

Based on the third aspect, in one possible implementation manner, the ventilation part has a first size in the second direction, and sliding the ventilation part from the first position to the second position along the second direction requires sliding the second size. The first dimension is less than or equal to the second dimension.

The movement interval of the ventilation part in the second direction is larger than the dimension of the ventilation part in the second direction, so that when the ventilation part moves in the second direction to give way to the first opening or the second opening, the first opening or the second opening has larger operation space, and the functional module can be conveniently pulled out from the first sub-cavity or the second sub-cavity.

Based on the third aspect, in one possible implementation manner, the mounting cavity has a third dimension along the second direction. The first dimension is greater than the third dimension.

The ventilation part of the server can completely cover the first sub-cavity and the second sub-cavity of the installation cavity in the second direction, and the air quantity of the ventilation part for conveying the first sub-cavity and the second sub-cavity is improved.

Based on the third aspect, in one possible implementation manner, the housing has two guide rail grooves that are spaced along the third direction, and the number of the guide rails in the air cooling module is two. The two guide rails are in one-to-one correspondence with the two guide rail grooves.

In this type of server, the ventilation part is supported by the two guide rails together, and the ventilation part is more stable in the process of moving in the first direction relative to the housing.

Based on the third aspect, in one possible implementation manner, the number of the air cooling modules is two, and the number of the installation cavities in the shell is two. The two mounting cavities are arranged in parallel along the second direction. The two air cooling modules are in one-to-one correspondence with the two mounting cavities.

In this server, two fan brackets are arranged in parallel along the second direction, and two mounting cavities are also formed in the corresponding housing. The capacity of the server accommodating the functional module is increased, and the performance of the server can be improved.

A fourth aspect of the embodiments of the present application provides a server, including an air-cooled module as in any implementation form of the second aspect or an air-cooled module as in any implementation form of the second aspect, and further including a housing. The housing has a mounting cavity therein, the mounting cavity including a first subchamber and a second subchamber juxtaposed in a second direction, the first subchamber having a first opening for inserting the functional module in the first direction, the second subchamber having a second opening for inserting the functional module in the first direction. The guide rail is in sliding fit with the housing along a first direction. The ventilation part can simultaneously shade the first opening and the second opening, and thereby simultaneously ventilate the first sub-cavity and the second sub-cavity through the first opening and the second opening. The ventilation part is slidable to a first position and a second position along a second direction relative to the guide rail. When the ventilation part is located at the first position relative to the guide rail, the second opening is opened. When the ventilation part is located at the second position relative to the guide rail, the first opening is opened. The server also includes a power distribution module. The power distribution module and the shell are connected to one end opposite to the air cooling module. The rail has a lead lumen extending in a first direction. The fan is electrically connected with the power distribution module through a conductive wire passing through the lead cavity.

The fan of the server is electrically connected with the power distribution module through the traction guide wire in the guide rail, so that on one hand, the conductive wire is protected, on the other hand, when the air cooling module moves parallel to the first direction, the conductive wire can follow deformation and move, the fan is kept in a state of being electrically connected with the power distribution module all the time, and abrasion of the conductive wire caused by relative movement of the guide rail and the shell can be reduced in the process. Also, the lead cavities may be reserved with a certain gap so that the length of the conductive wire has a sufficient margin, and when the ventilation part slides parallel to the second direction relative to the guide rail, the fan is also kept electrically connected with the power distribution module.

A fifth aspect of the embodiments of the present application provides a method for disassembling a functional module in a server, where the method is used for disassembling a functional module in a server in any implementation form of the second aspect, including:

driving the ventilation part away from the housing in parallel with the first direction;

driving the ventilation part to slide from a third position to a first position in parallel with the second direction, wherein the third position is positioned between the first position and the second position;

and taking out the functional module in the second subchamber from the second opening.

The functional module disassembling and assembling method can enable the ventilation part which corresponds to the second opening and ventilates to the second opening to be far away from the second opening through the sliding of the ventilation part parallel to the second direction, expose the functional module in the second sub-cavity, and take out the functional module in the second sub-cavity from the second opening.

Based on the fifth aspect, in a possible implementation manner, after the step of removing the functional module in the second sub-cavity from the second opening, the method further includes:

driving the ventilation part to slide to a second position in parallel with the second direction;

and taking out the functional module in the first subchamber from the first opening.

The functional module disassembling and assembling method can enable the ventilation part which corresponds to the first opening and ventilates to the first opening to be far away from the first opening through the sliding of the ventilation part parallel to the second direction, expose the functional module in the first sub-cavity, and take out the functional module in the first sub-cavity from the first opening.

driving the ventilation part to slide to a third position in parallel with the second direction;

in parallel to the first direction, the ventilation part is driven to be close to the shell, and the ventilation part simultaneously shields the first opening and the second opening.

The disassembly and assembly method of the functional module can enable the ventilation part to return to the position for shielding the first opening and the second opening simultaneously through the sliding of the ventilation part parallel to the second direction, and the ventilation part can ventilate the first sub-cavity and the second sub-cavity simultaneously.

Example 1

Fig. 1 shows a partial view of a server 001 provided in this embodiment, and a ventilation part 200 is provided near a housing 300. Fig. 2 shows a partial view of a server 001 provided in the present embodiment, the ventilation part 200 is disposed away from the housing 300, and the ventilation part 200 is located in a third position. Fig. 3 shows a partial view of a server 001 provided in this embodiment, the ventilation part 200 is disposed away from the housing 300, and the ventilation part 200 is located in the first position.

As shown in fig. 1 and 2, a first embodiment of the present application provides a server 001, where the server 001 includes an air cooling module 010, a housing 300, and a functional module 400 (please refer to fig. 3 in combination). For convenience of description, the spatial directions are defined in the first direction X, the second direction Y, and the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

The housing 300 has therein a mounting cavity 310 having an opening at one end in the first direction X. The mounting cavity 310 includes a first subchamber 311 and a second subchamber 313 juxtaposed in a second direction Y. The portion of the opening of the mounting cavity 310 corresponding to the first sub-cavity 311 forms a first opening 311a, and the portion of the opening of the mounting cavity 310 corresponding to the second sub-cavity 313 forms a second opening 313a. The functional module 400 is slidably engaged with the housing 300 in the first direction X. By sliding the functional module 400 in the first direction X relative to the housing 300, the functional module 400 can be slid into the first subchamber 311 via the first opening 311a or into the second subchamber 313 via the second opening 313a. Alternatively, the functional module 400 may be a storage module, a control module, or other modules that implement the functions of the server 001.

The air cooling module 010 includes a ventilation part 200 and two guide rails 100. The two guide rails 100 are respectively disposed at opposite ends of the ventilation part 200 in the third direction Z. The housing 300 has two guide rail 100 grooves extending in the first direction X, and the two guide rails 100 are respectively inserted into the two guide rail 100 grooves such that the guide rail 100 is slidably coupled with the housing 300 in the first direction X. When the guide rail 100 moves parallel to the first direction X with respect to the housing 300, the ventilation part 200 moves with the guide rail 100 parallel to the first direction X with respect to the housing 300 such that the ventilation part 200 is relatively close to or far from the housing 300. The ventilation unit 200 includes a frame 210 and a fan 230, the frame 210 is connected to the guide rail 100, and the fan 230 is disposed in a ventilation chamber 211a of the frame 210. The ventilation cavity 211a is penetrated in the first direction X, and the fan 230 may drive gas to penetrate the ventilation cavity 211a. It will be appreciated that the fan 230 module may also include only one guide rail 100, with the ventilation portion 200 being guided by one guide rail 100 to move in the first direction X relative to the housing 300.

Fig. 4 shows a partial view of a server 001 provided in this embodiment, the ventilation part 200 is disposed away from the housing 300, and the ventilation part 200 is located in the second position.

Referring to fig. 3 and 4 in combination, the ventilation part 200 is slidably coupled with the guide rail 100 in the second direction Y. In the second direction Y, the ventilation part 200 may be moved to a first position and a second position, and a third position between the first position and the second position, with respect to the guide rail 100. When the ventilation part 200 moves to the first position, the second opening 313a is opened, the functional module 400 may be loaded into the second sub-chamber 313 through the second opening 313a, and the functional module 400 in the chamber may be removed through the second opening 313a. When the ventilation part 200 moves to the second position, the first opening 311a is opened, the functional module 400 may be loaded into the first sub-chamber 311 through the first opening 311a, and the functional module 400 in the first sub-chamber 311 may be taken out through the first opening 311 a. When the ventilation part 200 moves to the third position, the ventilation part 200 simultaneously shields the first opening 311a and the second opening 313a in the first direction X. The ventilation part 200 located at the third position can simultaneously protect the functional modules 400 in the first sub-chamber 311 and the second sub-chamber 313, prevent the functional modules 400 in the first sub-chamber 311 and the second sub-chamber 313 from sliding out, and simultaneously ventilate and cool the functional modules 400 in the first sub-chamber 311 and the second sub-chamber 313.

Optionally, a positioning member (not shown) is further disposed on the frame 210, and a positioning slot (not shown) is further disposed on the housing 300. When the ventilation part 200 approaches the housing 300 in the first direction X, the positioning member is inserted into the positioning groove, and the ventilation part 200 is locked against displacement relative to the housing 300 in the second direction Y by the engagement of the positioning member and the positioning groove. At this time, the ventilation part 200 is relatively fixed to the guide rail 100 in the second direction Y. Before releasing the displacement lock of the ventilation part 200 relative to the guide rail 100 in the second direction Y, the ventilation part 200 is first parallel to the first direction X so as to be away from the housing 300, and the positioning member is separated from the positioning groove.

Fig. 5 is a cross-sectional view of a connection between the main body 211 and the guide rail 100 according to an embodiment of the present application.

Referring to fig. 3, 4 and 5, optionally, the air cooling module 010 further includes a stop portion 500, and the ventilation portion 200 and the guide rail 100 are provided with the stop portion 500. The stopper 500 includes a first stopper 510 and a second stopper 530 provided to the frame 210, a third stopper 550 provided to one rail 100, and a fourth stopper 570 provided to the other rail 100. When the ventilating portion 200 moves to the first position with respect to the guide rail 100, the first stopper block 510 contacts with the third stopper block 550, and the third stopper block 550 restricts the first stopper block 510 from moving further in a direction away from the second position by continuing to move parallel to the second direction Y. When the ventilating portion 200 moves to the second position with respect to the guide rail 100, the second stopper piece 530 contacts with the fourth stopper piece 570, and the fourth stopper piece 570 restricts the second stopper piece 530 from continuing to move parallel to the second direction Y, thereby restricting the ventilating portion 200 from moving further away from the first position. It will be appreciated that instead of providing the third stop block 550 or the fourth stop block 570 extending perpendicular to the second direction Y on the guide rail 100, only the first stop block 510 and the second stop block 530 cooperating with the guide rail 100 may be provided on the ventilating portion 200, thereby restricting the movement of the ventilating portion 200 relative to the guide rail 100 in the second direction Y.

Referring back to fig. 2, 3 and 4, optionally, the frame 210 includes a main body 211 and a first sliding rail 213. The first slide rail 213 is disposed at one end of the main body 211 in the third direction Z. The guide rail 100 is provided with a second slide rail 101 at one end in the first direction X. The frame 210 and the guide rail 100 are connected by the cooperation of the first slide rail 213 and the second slide rail 101. The second slide rail 101 extends in the second direction Y. The first sliding rail 213 and the second sliding rail 101 are slidably engaged, so that the frame 210 can slide along the second direction Y relative to the guide rail 100. The first rail 213 is a substantially U-shaped rail in a cross section perpendicular to the second direction Y, and a guide groove 2131 having an opening toward the third direction Z is formed in the first rail 213. The second slide rail 101 protrudes in the third direction Z on the guide rail 100, the second slide rail 101 is inserted into the guide groove 2131 from the opening of the guide groove 2131, and the position of the second slide rail 101 in the first direction X and the third direction Z is restricted by the inner wall of the guide groove 2131, and accordingly, the position of the second slide rail 101 in the first direction X and the third direction Z can be restricted by the inner wall of the guide groove 2131 acting on the inner wall of the guide groove 2131. The first slide rail 213 enables the second slide rail 101 to guide the first slide rail 213 to move in the second direction Y when the first slide rail 213 and the second slide rail 101 are mated.

It will be appreciated that the movement of the frame 210 relative to the rail 100 in the second direction Y may take other forms to effect the guiding. For example, a gear is provided on the guide rail 100, a rack extending in the second direction Y is provided on the frame 210, and the gear on the guide rail 100 is engaged with the rack on the frame 210. When the gears on the driving rail 100 rotate, the frame 210 is driven to move in the second direction Y. Gears are disposed on both guide rails 100, and racks engaged with the gears are disposed on both sides of the frame 210 opposite to each other in the third direction Z, so that the frame 210 can be maintained to move smoothly in the second direction Y when the gears are rotated synchronously. For another example, the first rail 213 is not a U-shaped rail in a cross section perpendicular to the second direction Y, but includes two driving rollers. The two driving rollers are disposed on two opposite sides of the second slide rail 101 along the first direction X. After the second sliding rail 101 is clamped by the two driving rollers, when the two driving rollers rotate, the second sliding rail 101 can move relative to the two driving rollers in the second direction Y through friction force.

Alternatively, the main body 211 includes first and second baffles 2111 and 2113 spaced apart along the second direction Y. Three separators 2115 and two end plates 2117 are also provided between the first baffle 2111 and the second baffle 2113. Two first slide rails 213 correspond to two end plates 2117, and each first slide rail 213 is fixedly connected to one end plate 2117. A three-partition plate 2115 is located between the two end plates 2117, forming a space between the first baffle plate 2111 and the second baffle plate 2113 into four ventilation chambers 211a juxtaposed in the third direction Z. One fan 230 is provided in each ventilation chamber 211a. After the fan 230 is disposed in the ventilation cavity 211a, the fan 230 may be connected to the frame 210 by a fastening manner, so as to keep the fan 230 stable during operation and reduce the probability of the fan 230 falling out of the ventilation cavity 211a. The first baffle 2111 and the second baffle 2113 may limit the position of the fan 230 in the second direction Y, so that the fan 230 can be driven to move along the second direction Y relative to the guide rail 100 during the movement of the main body 211 along the second direction Y relative to the guide rail 100. Of course, in some other embodiments, the main body 211 may not include the first baffle 2111 or the second baffle 2113, for example, the main body 211 includes only the first baffle 2111, and the plurality of ventilation chambers 211a are formed by fixedly connecting the first baffle 2111 with the plurality of partition plates 2115. After being disposed within the ventilation chamber 211a, the fan 230 is fixedly coupled to the partition 2115 or the first baffle 2111, such that the fan 230 can move in the second direction Y with respect to the guide rail 100 along with the first baffle 2111.

Alternatively, the ventilation part 200 has a first dimension in the second direction Y, and sliding the ventilation part 200 from the first position to the second position requires sliding the second dimension parallel to the second direction Y. The first size is equal to or smaller than the second size, so that the ventilation part 200 can have a larger movement section in the second direction Y. When the ventilation part 200 has a large movement section in the second direction Y, the first position and the second position are spaced apart from each other. When the ventilation part 200 is located at the first position, the second opening 313a can be completely opened, even with a certain additional space for an operator to operate at the second opening 313a, reducing the difficulty of removing the functional module 400 in the second subchamber 313 from the second opening 313 a. Also, when the ventilation part 200 is located at the second position, the first opening 311a can be completely opened, even with a certain additional space for an operator to operate at the first opening 311a, thereby reducing the difficulty of removing the functional module 400 in the first sub-cavity 311 from the first opening 311 a.

Optionally, when the fan 230 is accommodated in the rack 210, the size of the rack 210 along the second direction Y is substantially equal to the size of the housing 300 along the second direction Y. When the ventilation unit 200 is disposed close to the rack 210, both surfaces of the ventilation unit 200 facing the housing 300 in the second direction Y are substantially flat, and the overall appearance of the server 001 can be maintained. In this embodiment, the mounting cavity 310 has a third dimension along the second direction Y, and the first dimension is equal to or greater than the third dimension, thereby ensuring that two opposite sides of the ventilation part 200 and the housing 300 in the second direction Y are substantially formed in a plane.

The server 001 in this embodiment is a 2U server 001, and in the second direction Y, the size of the housing 300 is 2U, and the size of the fan 230 is 80mm. Such a fan 230 is also called 80 fan 230, and is double the size of a 40 fan having a size of 40mm in the second direction Y. When the ventilation part 200 is close to the case 300, the fan 230 may correspond to both the first sub-chamber 311 and the second sub-chamber 313, so that the fan 230 can ventilate both the first sub-chamber 311 and the second sub-chamber 313. When U is a length unit, each U corresponds to 44.45mm.

The ventilating and cooling effect of the server 001 to the first sub-chamber 311 and the second sub-chamber 313 is simultaneously performed using the fan 230 having a size approximately equivalent to 2U, and is greater than that to the first sub-chamber 311 and the second sub-chamber 313 using two 40 fans, respectively. On the one hand, the motor volume of the fan 230 is multiplied, and the power is multiplied, so that the rotating speed of the fan 230 is multiplied. On the other hand, one 80 fan 230 has lower power consumption than two 40 fans, and can reduce the overall power consumption of the server 001.

Optionally, the method may be performed in a single-stage process, as the fan 230, an 8038 fan 230 (80×80×38mm in length, height and thickness, respectively, of the fan 230), an 8056 fan 230 (length, height and thickness, respectively) fans 230 having dimensions of 80×80×56mm in height and thickness, respectively, or 8080 fans 230 (length fans 230 having respective dimensions of 80 x 80mm in height and thickness). The fans 230 each have a size of 80mm in the second direction Y and are capable of simultaneously corresponding to the first sub-chamber 311 and the second sub-chamber 313 while ventilating the first sub-chamber 311 and the second sub-chamber 313. When the fan 230 is installed in the ventilation cavity 211a, the length dimension of the fan 230 is the dimension in the second direction Y, the height dimension of the fan 230 is the dimension in the third direction Z, and the thickness dimension of the fan 230 is the dimension in the first direction X.

Fig. 6 shows a cross-sectional view of the guide rail 100 provided by the present embodiment. Fig. 7 shows a schematic diagram of the connection between the fan 230 and the power distribution module 600 according to the present embodiment.

Referring to fig. 6 and 7, optionally, the server 001 further includes a power distribution module 600. The power distribution module 600 is fixedly connected with the housing 300. The power distribution module 600 is located at an end of the housing 300 facing away from the ventilation part 200. The guide rail 100 is provided with a lead cavity 110, and the lead cavity 110 extends along the first direction X and penetrates the whole guide rail 100. The server 001 further includes a conductive wire 610, wherein the conductive wire 610 passes through the lead cavity 110, and the fan 230 and the power distribution module 600 are respectively connected to both ends of the conductive wire 610, so that the fan 230 is electrically connected to the power distribution module 600. When the power distribution module 600 supplies power to the fan 230 through the conductive wires 610, the fan 230 rotates to thereby achieve ventilation cooling of the first and second sub-chambers 311 and 313. The lead cavity 110 can protect the conductive wire 610, and when the air cooling module 010 moves parallel to the first direction X relative to the housing 300, the guide rail 100 drives the conductive wire 610 to move together, so as to reduce the risk of damage caused by friction between the conductive wire 610 and the housing 300. And the conductive wires 610 within the lead cavity 110 may have a certain margin such that when the ventilation part 200 is away from the housing 300 in parallel to the first direction X, the conductive wires 610 are stretched, but the electrical connection of the fan 230 and the power distribution module 600 is maintained. As the ventilation part 200 approaches the case 300 again in parallel to the first direction X, the conductive wire 610 is received by bending and shrinking in the lead cavity 110. Further, a communication cavity may be further provided in the second sliding rail 101 and the first sliding rail 213, and the conductive wire 610 may also pass through the communication cavity, so that the ventilation part 200 may also remain connected to the conductive wire 610 when moving between the first position and the second position. The fan 230 can be electrically connected to the power distribution module 600 during the movement of the air cooling module 010 in parallel to the first direction X toward or away from the housing 300, and during the relative movement of the ventilation part 200 in the first position and the second position with respect to the guide rail 100.

It should be noted that, if the mounting cavity 310 further includes a third sub-cavity parallel to the second sub-cavity 313 along the second direction Y, and the third sub-cavity is located at a position of the second sub-cavity 313 away from the first sub-cavity 311, the size of the fan 230 may be further increased, the ventilation portion 200 may be moved to the first position parallel to the second direction Y to simultaneously open the second sub-cavity 313 and the third sub-cavity, and the ventilation portion 200 may be moved to the second position parallel to the second direction Y to simultaneously open the first sub-cavity 311 and the second sub-cavity 313. It will be appreciated that as the fourth, fifth, or other subchambers are further added to the mounting chamber 310, the size of the fan 230 may be further increased and more subchambers within the mounting chamber 310 may be opened when the vent 200 is in the first and second positions.

In this server 001, each fan 230 corresponds to the functional modules in the first sub-cavity 311 and the second sub-cavity 313 arranged along the second direction Y at the same time, and the larger fan 230 is used to ventilate and dissipate heat of the functional modules, so as to improve the heat dissipation effect of the functional modules. And the power consumption of one 80 fan 230 is significantly lower than that of two 40 fans, so that the power consumption ratio of the fans 230 in the server 001 can be reduced. The ventilation part 200 can move along the second direction Y relative to the guide rail 100, so as to open the first opening 311a or the second opening 313a, and facilitate replacement of the functional modules in the first sub-cavity 311 and the second sub-cavity 313, where the replacement of the functional modules may be hot plugging of the functional modules. In the hot plug process of one functional module, other functional modules which do not need to be plugged can continue to operate. In the hot plug process of the functional module, only the ventilation part 200 is required to move along the first direction X and the second direction Y relative to the housing 300, and the ventilation part 200 is not required to be completely detached from the housing 300, so that the hot plug process of the functional module 400 can be effectively simplified.

As shown in fig. 8, the second embodiment of the present application provides a server 001, and the server 001 is different from the server 001 of the first embodiment only in that: the server 001 in the present embodiment is a 4U server 001, and the size of the housing 300 in the second direction Y is 4U. Two groups of mounting cavities 310 are arranged in the shell 300 in parallel along the second direction Y, and each group of mounting cavities 310 corresponds to one air cooling module 010.

Example III

Fig. 9 is a flow chart illustrating a method for disassembling and assembling the functional module 400 according to the present embodiment.

As shown in fig. 9, a third embodiment of the present application provides a method for disassembling and assembling a functional module 400. This method of disassembling the functional module 400 is used to disassemble the functional module 400 in the server 001 in the first embodiment. The method for disassembling and assembling the functional module 400 comprises the following steps:

s101, parallel to the first direction X, the ventilation part 200 is driven away from the case 300. In this process, the guide rail 100 slides in the guide rail 100 groove of the housing 300, and the positioning piece of the ventilation part 200 is disengaged from the positioning groove of the housing 300, and the displacement lock of the ventilation part 200 with respect to the guide rail 100 in the second direction Y is released.

S102, parallel to the second direction Y, the ventilation part 200 is driven to slide from a third position to the first position, and the third position is located between the first position and the second position. When the ventilation part 200 slides to the first position, the second opening 313a exposes the functional module 400 in the second sub-chamber 313.

S103, the functional module 400 in the second subchamber 313 is taken out from the second opening 313 a. The functional module 400 slides out of the second subchamber 313 parallel to the first direction X.

When the functional module 400 in the first sub-cavity 311 needs to be removed, the step S103 may further include the steps of:

s104, parallel to the second direction Y, the ventilation part 200 is driven to slide to the second position. When the ventilation part 200 slides to the second position, the first opening 311a exposes the functional module 400 in the first sub-chamber 311.

S105, the functional module 400 in the first sub-chamber 311 is taken out from the first opening 311 a. The functional module 400 slides out of the first sub-cavity 311 parallel to the first direction X.

After the functional module in the server 001 is taken out, the ventilation unit 200 needs to be restored to be close to the housing 300, so that the fan 230 ventilates the first sub-chamber 311 and the second sub-chamber 313, and after step S105, the method further includes the steps of: after the step of removing the functional module 400 in the second subchamber 313 from the second opening 313a, it further comprises:

s106, parallel to the second direction Y, the ventilation part 200 is driven to slide to the third position. When the ventilation part 200 slides to the third position, the positioning piece of the ventilation part 200 is aligned with the positioning groove of the housing 300.

S107, parallel to the first direction X, the ventilation part 200 is driven close to the case 300, and the ventilation part 200 ventilates the first opening 311a and the second opening 313a at the same time. The positioning piece of the ventilation part 200 is inserted into the positioning groove of the housing 300, and the displacement of the ventilation part 200 in the second direction Y relative to the housing 300 is locked.

It will be appreciated that the steps of S102 and S103 may be exchanged with the steps of S104 and S105 in order. S104 and S105 are performed first and S102 and S103 are performed next. When executing S104 and S105, the functional module in the first sub-cavity 311 can be taken out first, and then the functional module in the second sub-cavity 313 can be taken out.

The above-mentioned function module 400 assembling and disassembling method for disassembling two function modules 400 in the server 001 includes the steps of:

s101, parallel to the first direction X, the ventilation part 200 is driven away from the case 300.

S102, parallel to the second direction Y, the ventilation part 200 is driven to slide from a third position to the first position, and the third position is located between the first position and the second position.

S103, the functional module 400 in the second subchamber 313 is taken out from the second opening 313 a.

S104, parallel to the second direction Y, the ventilation part 200 is driven to slide to the second position.

S105, the functional module 400 in the first sub-chamber 311 is taken out from the first opening 311 a.

S106, parallel to the second direction Y, the ventilation part 200 is driven to slide to the third position.

S107, parallel to the first direction X, the ventilation part 200 is driven close to the case 300, and the ventilation part 200 ventilates the first opening 311a and the second opening 313a at the same time.

It will be appreciated that if only the functional module in the second sub-chamber 313 needs to be removed, S104 and S105 need not be supported after S103 is performed, and S106 and S107 are directly performed. Similarly, if only the functional module in the first sub-cavity 311 needs to be removed, S104 and S105 may be executed first, and then S102 and S103 may not be executed, but S106 and S107 may be executed directly.

It can be understood that the method for assembling and disassembling the functional module 400 when used for loading the functional module 400 in the server 001 in the first embodiment includes the following steps after step S102:

s103' loads the functional module 400 into the second subchamber 313 through the second opening 313 a. The functional module 400 slides into the second subchamber 313 parallel to the first direction X.

When the functional module 400 is further required to be loaded into the first sub-cavity 311, the step S104 may further include the steps of:

s105' loads the functional module 400 into the first sub-chamber 311 through the first opening 311 a. The functional module 400 slides into the first sub-cavity 311 parallel to the first direction X.

The method for mounting and dismounting the functional modules 400 of the two functional modules 400 in the loading server 001 includes the steps of:

S103' loads the functional module 400 into the second subchamber 313 through the second opening 313 a.

S105' loads the functional module 400 into the first sub-chamber 311 through the first opening 311 a.

The method for disassembling and assembling the functional module 400 can move the ventilation part 200 of the first sub-cavity 311 and the second sub-cavity 313 to the position capable of disassembling or loading the functional module 400, so that the functional module 400 is disassembled or loaded, and after the functional module 400 is disassembled or loaded, the ventilation part 200 can be reinstalled to the position close to the shell 300, and the air cooling module 010 is not completely disassembled from the shell 300 in the whole process, so that the connection between the air cooling module 010 and the shell 300 is maintained, and the disassembling and assembling difficulty of the functional module 400 is reduced.
