[0002] Server racks in cloud computing rooms are one of the key infrastructures of cloud data centers. The structure of a cloud computing room server rack is relatively complex. From the outside, it generally has a front door, a rear door, and side panels. The front door is usually transparent for easy observation of the equipment status. The rear door is mainly used for cabling and equipment maintenance. The side panels protect the equipment and maintain the stability of the rack structure. Inside the rack, multiple support platforms are typically installed at equal intervals to support the servers. To improve the stability of server operation, cooling equipment is generally installed on the rack, including both air cooling and water cooling. However, cooling server racks has the following drawbacks:

[0003] After installing servers on the racks, there may be a small number of servers, which means that some racks do not need to be equipped with servers. When dissipating heat, the entire rack is cooled directly, which makes it difficult to achieve precise cooling of the servers and results in a waste of cooling energy. Summary of the Invention

An internal groove is opened inside the bottom rod, and a bottom spring is installed inside the internal groove. The two ends of the bottom spring are fixedly connected to the inner top wall of the internal groove and the inner bottom wall of the lower cylinder, respectively.

[0012] Preferably, the fixed partition has a storage groove inside, and a movable partition is movably installed inside the storage groove.

One end of one connecting plate is fixedly connected to the bottom end of one side of the movable partition, and the other connecting plate passes through the slide groove and is fixedly connected to the bottom rod.

[0013] Preferably, the negative pressure control unit includes negative pressure cylinders symmetrically installed on both sides of the top of the support plate.

[0015] Preferably, a cooling method for a cloud computer room server rack cooling device is as follows:

[0016] S1. Server installation: A cooling water tank is installed between the inlet pipe and the return pipe. Place the server to be installed on the top of the support plate and press the support plate down to create a negative pressure fixing effect between the ring suction cup and the server.

[0017] S2, Cooling Start: After the support plate moves downward, pull the baffle into the plate slot to open the connecting slot, so that the heat dissipation cavity and the water channel are connected.

[0018] S3. Cooling: Turn on the pump in the cooling water tank so that the cooling water enters the side cooling tank from the inlet pipe and carries away the server's heat through the heat dissipation cavity inside the cooling tank, thereby cooling the server. Then the cooling water flows back to the cooling water tank from the return pipe for circulation cooling.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1) During operation, the server is installed on the support plate, and the support plate is pressed down to close the top of the mounting cavity, preventing the cooling water from overflowing during cooling. At the same time, the baffle is pulled into the plate groove by the connecting rod to open the connecting groove, so that the heat dissipation cavity is connected to the water channel, and the support platform on which the server is installed can dissipate heat, achieving a precise heat dissipation effect and improving cooling energy efficiency.

[0021] 2) During operation, the top wall of the annular suction cup is in close contact with the bottom wall of the server housing, and the support plate moves downward, causing the piston block and the negative pressure cylinder to move relative to each other, so that the annular suction cup and the server are fixed by negative pressure, which makes it easy to fix the server. At the same time, when the stopper rotates to the point where the second vent hole corresponds to the first vent hole, the negative pressure can be released, which makes it easy to disassemble the server.

[0022] 3) During operation, when the ring suction cup is used to adsorb the server under negative pressure, the top wall of the piston plate contacts the top wall of the upper cylinder under the action of negative pressure, and the bottom spring is in a stretched state. When the server heats up severely, the air inside the negative pressure box expands due to heat, increasing the air pressure. Under the elastic force of the bottom spring, the piston plate moves downward to ensure the negative pressure between the ring suction cup and the server, thereby improving the stability of fixing the server.

[0023] 4) During operation, a movable partition is slidably installed in the storage groove inside the fixed partition. A water flow gap is formed between the bottom end of the movable partition and the inner bottom wall of the heat dissipation cavity. When the server heats up severely, the piston plate moves downward and drives the movable partition to move upward through the rotating gear and rack, thereby increasing the water flow gap and accelerating the cooling water flow speed. This improves the heat dissipation and cooling speed, making the heat dissipation and cooling speed match the heat dissipation of the server, thus achieving energy saving and avoiding the situation where the cooling effect is large but the heat dissipation is not severe.

[0024] 5) During operation, the support plate above the support platform is used to place the server, and the two side panels of the cabinet are equipped with side cooling slots. The cooling water flowing in the side cooling slots can cool the cabinet. At the same time, when the server is installed, the heat dissipation cavity on the support platform is in the open state, which facilitates the heat dissipation and cooling of the corresponding server and improves the heat dissipation and cooling effect.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Depend on Figure 1-9 The present invention relates to a server rack cooling device for a cloud computer room, comprising a rack 1, server support components 2 are installed equidistantly inside the rack 1, the server support components 2 are used to place servers and cool and dissipate heat from the servers, side cooling grooves 3 are provided inside the two side panels of the rack 1, water channels 4 are provided equidistantly on the side of the two side cooling grooves 3 that are close to each other, and the water channels 4 on both sides correspond to one of the server support components 2 respectively, a water inlet pipe 5 is installed on the top side of one side cooling groove 3, and a return pipe 6 is installed on the bottom side of the other side cooling groove 3, and a cooling water tank for outputting cooling water is installed between the water inlet pipe 5 and the return pipe 6.

[0039] Server support assembly 2 includes support platforms 201 equidistantly installed inside cabinet 1. An installation cavity 202 is formed inside the support platform 201, extending to the top of the support platform 201. A support plate 203 is positioned above the support platform 201, and a cooling box 204 is installed at the bottom of the support plate 203. The outer wall of the cooling box 204 is in close contact with the inner wall of the installation cavity 202. A cooling switch unit 205 is installed between the support plate 203 and the support platform 201, and the cooling switch unit 205 is used to activate the cooling system. Alternatively, the cooling box 204 is equipped with an internal heat dissipation unit 206, and a negative pressure control unit 208 is installed on the support plate 203. The support plate 203 above the support platform 201 is used to place the server, and the two side panels of the cabinet 1 are provided with side cooling grooves 3. The cooling water flowing in the side cooling grooves 3 can cool the cabinet 1. At the same time, when the server is installed, the heat dissipation components on the support platform 201 are in the open state, so as to facilitate the heat dissipation and cooling of the corresponding server and improve the heat dissipation and cooling effect.

[0040] The cooling switch unit 205 includes two symmetrically arranged connecting grooves 2051 at both ends of the mounting cavity 202. The two connecting grooves 2051 extend to both ends of the support platform 201, and each connecting groove 2051 corresponds to a water channel 4 on either side. Plate grooves 2052 are symmetrically arranged at both ends of the connecting grooves 2051. A baffle 2053 is slidably installed inside the plate groove 2052. The outer wall of the baffle 2053 is in close contact with the inner wall of the plate groove 2052. The ends of the baffles 2053 that are close to each other tightly seal the connecting grooves 2051. Rod grooves 2054 are provided at the top of the ends of the plate grooves 2052 on the same side, and pressure rods 2056 are movably installed inside the rod grooves 2054. A connecting rod 2055 is provided between the server and the baffle 2053. The two ends of the connecting rod 2055 are hinged to the baffle 2053 and the pressure rod 2056, respectively. The pressure rod 2056 is fixedly installed at the bottom of the support plate 203. The server is installed above the support plate 203. Pressing the support plate 203 downwards causes it to close the top of the mounting cavity 202, preventing cooling water from overflowing during cooling. At the same time, the connecting rod 2055 pulls the baffle 2053 into the plate groove 2052, opening the connecting groove 2051 and connecting the heat dissipation cavity 2061 with the water channel 4. This allows the support platform 201 on which the server is installed to dissipate heat, achieving precise heat dissipation and improving cooling energy efficiency.

[0041] The internal heat dissipation unit 206 includes a heat dissipation cavity 2061 formed inside the cooling box 204. Both ends of the heat dissipation cavity 2061 extend to both ends of the cooling box 204. Two fixed partitions 2062 are symmetrically installed on the inner top wall of the heat dissipation cavity 2061. The area between the two fixed partitions 2062 forms a cooling control cavity. A cooling control unit 207 is disposed inside the cooling control cavity. Two peripheral cooling cavities are formed on the sides of the two fixed partitions 2062 that are far apart from each other. The sides of the two fixed partitions 2062 that are far apart from each other are equidistantly equipped with… The cooling control cavity has a heat sink 2063 and heat-conducting rods 2067 are evenly installed inside. The top of the heat-conducting rods 2067 is located on the upper surface of the support plate 203. Drainage holes 2066 are evenly opened on the bottom wall of the heat sink 2061. Bottom holes 2064 are opened at the four corners of the inner bottom wall of the heat sink 2061. A return spring 2065 is installed inside the bottom hole 2064. The top of the return spring 2065 is fixedly connected to the inner top wall of the heat sink 2061, and the bottom of the return spring 2065 is fixedly connected to the inner bottom wall of the mounting cavity 202.

[0042] The cooling control unit 207 includes annular suction cups 2071 equidistantly mounted on the top of the support plate 203. A negative pressure box 2072 is installed on the inner top wall of the cooling control cavity. The negative pressure box 2072 is connected to the inner cavity of the annular suction cups 2071. An upper cylinder 2073 is installed at the bottom end of the negative pressure box 2072. A through hole is opened between the upper cylinder 2073 and the negative pressure box 2072. A lower cylinder 2074 is installed between the bottom end of the upper cylinder 2073 and the bottom wall of the cooling control cavity. Sliding grooves 2075 are symmetrically opened on both sides of the lower cylinder 2074. A piston plate 20711 moves inside the upper cylinder 2073. A bottom rod 20712 is installed at the bottom end of the piston plate 20711. The lower cylinder 2074 has an internal groove 20713, inside which a bottom spring 20714 is installed. The two ends of the bottom spring 20714 are fixedly connected to the inner top wall of the internal groove 20713 and the inner bottom wall of the lower cylinder 2074, respectively. A storage slot 2076 is provided inside the fixed partition 2062, and a movable partition 2077 is movably installed inside the storage slot 2076. The bottom end of the movable partition 2077 is located below the storage slot 2076. Gear mounting brackets are symmetrically arranged on both sides of the lower cylinder 2074. The gear mounting brackets are fixedly installed inside the cooling control cavity, and rotating gears 2078 are rotatably mounted on the gear mounting brackets. Racks 20 are meshed on both sides of the rotating gears 2078. 79. Connecting plates 20710 are installed on the opposite sides of the two racks 2079. One end of one connecting plate 20710 is fixedly connected to the bottom side of the movable partition 2077, and the other connecting plate 20710 passes through the slide groove 2075 and is fixedly connected to the bottom rod 20712. When the annular suction cup 2071 is subjected to negative pressure adsorption with the server, the top wall of the piston plate 20711 contacts the inner top wall of the upper cylinder 2073 under the action of negative pressure, and the bottom spring 20714 is in a stretched state. When the server heats up severely, the air inside the negative pressure box 2072 expands due to heat, increasing the air pressure. Under the elastic force of the bottom spring 20714, the piston plate 20711 moves downward to ensure the annular suction cup... The negative pressure between the disk 2071 and the server improves the stability of the server. A movable partition 2077 is slidably installed in the storage groove 2076 inside the fixed partition 2062. A water flow gap is formed between the bottom end of the movable partition 2077 and the inner bottom wall of the heat dissipation cavity 2061. When the server heats up severely, the piston plate 20711 moves downward and drives the movable partition 2077 upward through the rotating gear 2078 and rack 2079, which increases the water flow gap accordingly, speeds up the cooling water flow, and improves the heat dissipation and cooling speed. This makes the heat dissipation and cooling speed match the heat dissipation of the server, which has an energy-saving effect and avoids the situation where the cooling effect is large but the heat dissipation is not severe.

[0043] The negative pressure control unit 208 includes negative pressure cylinders 2081 symmetrically installed on both sides of the top of the support plate 203. A venting groove 2082 is provided inside the support plate 203, connecting the negative pressure box 2072 and the negative pressure cylinders 2081. A piston block 2083 is provided inside the negative pressure cylinder 2081, with its outer wall tightly against the inner wall of the negative pressure cylinder 2081. A fixing plate 2084 is installed at the top of the piston block 2083, and is fixedly connected to the inner wall of the cabinet 1. A side cylinder 2085 is fixed to one side of the negative pressure cylinder 2081, and the side cylinder 2085 has symmetrically provided first vent holes 2086 on the side closest to the negative pressure cylinder 2081. The first vent 2086 is connected to the negative pressure cylinder 2081. A stopper 2087 is rotatably installed inside the side cylinder 2085. A second vent 2088 is symmetrically opened on the stopper 2087. A knob 2089 is installed on one side of the stopper 2087. The top wall of the annular suction cup 2071 is in close contact with the bottom wall of the server housing. The support plate 203 moves downward, causing the piston block 2083 and the negative pressure cylinder 2081 to move relative to each other, so that the annular suction cup 2071 and the server are fixed by negative pressure, which facilitates the fixation of the server. At the same time, when the stopper 2087 rotates to the point where the second vent 2088 corresponds to the first vent 2086, the negative pressure can be released, which facilitates the disassembly of the server.

[0044] Working principle: During operation, the required server is first placed on the support plate 203 for installation. When the server is placed, it exerts downward pressure on the support plate 203, thereby pushing the support plate 203 downward until the bottom wall of the cooling box 204 contacts the inner bottom wall of the mounting cavity 202, causing the return spring 2065 to compress. The following changes occur during the downward movement of the support plate 203:

[0045] First, the support plate 203 moves downward, causing the negative pressure cylinder 2081 to move downward. Since the piston block 2083 inside the negative pressure cylinder 2081 is fixedly connected to the inner wall of the cabinet 1, the downward movement of the support plate 203 causes the negative pressure cylinder 2081 and the piston block 2083 to move relative to each other. Since the top wall of the annular suction cup 2071 is in close contact with the bottom wall of the server housing, the top of the annular suction cup 2071, the bottom wall of the piston block 2083, and the top wall of the piston plate 20711 form a sealed space, which causes the annular suction cup 2071 to generate a negative pressure force on the server, thereby fixing the server under negative pressure and facilitating the installation of the server. At the same time, under the action of negative pressure, the top wall of the piston plate 20711 is in close contact with the inner top wall of the upper cylinder 2073, and the bottom spring 20714 is in a stretched state.

[0046] Meanwhile, when the support plate 203 moves downward, the pressure rod 2056 moves downward, and then the connecting rod 2055 pulls the two baffles 2053 to move apart along the plate groove 2052, so that the connecting groove 2051 opens. At this time, the heat dissipation cavity 2061 is connected to the water channel 4 through the connecting groove 2051, so that the cooling water can enter the heat dissipation cavity 2061 for heat dissipation and cooling. When the cooling water flows through the heat dissipation plate 2063 and the heat conduction rod 2067, it carries away the heat from the server and completes the cooling and heat dissipation.

[0047] When the top wall of the piston plate 20711 contacts the inner top wall of the upper cylinder 2073, under the action of the rotating gear 2078, the movable partition 2077 is at its lowest limit position, and a water flow gap is formed between the movable partition 2077 and the inner bottom wall of the heat dissipation cavity 2061. At this time, the height of the water flow gap is the smallest. The smaller the water flow gap, the slower the cooling water flows. When the server is working, the temperature rises continuously, causing the air inside the negative pressure box 2072 to expand due to heat, which increases the air pressure inside the negative pressure box 2072. At this time, the piston plate 20711 moves downward under the elastic force of the bottom spring 20714, thereby ensuring the negative pressure fixing strength between the annular suction cup 2071 and the server and improving the installation stability of the server.

[0048] When the piston plate 20711 moves downward, it drives the movable partition 2077 to move upward by rotating the gear 2078 and rack 2079, which increases the gap through which the water flows, thereby speeding up the flow of cooling water and improving the heat dissipation and cooling speed. This makes the heat dissipation and cooling speed match the heat generation of the server, achieving energy saving and avoiding the situation where the cooling effect is large but the heat generation is not serious.

[0049] When in use, the pump body of the cooling water tank is turned on, so that the cooling water can enter the side cooling tank 3 on one side through the water inlet pipe 5, and enter the other side cooling tank 3 through the water channel 4 and heat dissipation cavity 2061. It then flows back to the cooling water tank through the return pipe 6 for cooling, thus completing the water cooling of the server and the cabinet 1.

[0050] When the server needs to be disassembled, the stopper 2087 is rotated by knob 2089 until the second vent 2088 corresponds to the first vent 2086, allowing outside air to enter the negative pressure cylinder 2081, thereby releasing the negative pressure and facilitating the disassembly of the server.
