Technical Field

[0001] The invention relates to the technical field of ventilation floors, in particular to an adjustable ventilation floor driven by a high expansion alloy. Background Art

[0002] Adjustable ventilation floor is a device specially used in data center and other places where the ambient temperature needs to be precisely adjusted. This floor can automatically adjust the opening of the vents according to the temperature in the room, thereby controlling the amount of cold air sent into the room to maintain a temperature range suitable for long-term stable operation of servers and other equipment.

[0003] The most common ventilation floor structure at present is to change the ventilation area and adjust the air supply volume by the relative movement between the movable wind shield and the fixed wind shield. Specifically, a rack is installed on the movable wind shield, and a gear is driven by a motor to rotate, and the gear drives the rack to realize the linear movement of the wind shield.

[0004] However, this adjustment method has the following problems: High cost: It requires a more complex motor drive control system. Complex automatic control: In addition to the ventilation floor itself, it is also necessary to install a temperature sensor in the computer room and equip it with a controller to achieve linkage control between the temperature sensor and the ventilation floor.

[0008] The temperature sensing component includes a shell suspended on a chassis, a high expansion alloy strip is arranged inside the shell, and the high expansion alloy strip is arranged in the shape of an Archimedean spiral. A plurality of guide rollers arranged in a spiral line are arranged on the outside of the high expansion alloy strip to limit the telescopic direction of the high expansion alloy strip. A multi-stage telescopic gas rod is arranged at the end of the high expansion alloy strip, and the multi-stage telescopic gas rod is connected to the pneumatic part through a hose.

[0010] As a preferred solution of the adjustable ventilated floor driven by high expansion alloy described in the present invention, the pneumatic part includes a multi-stage telescopic gas rod 2 and a switching valve, wherein the free end of the multi-stage telescopic gas rod 2 is fixed to the side of the sliding foot, and the fixed end of the multi-stage telescopic gas rod 2 is connected to the switching valve.

[0011] As a preferred solution of the adjustable ventilated floor driven by high expansion alloy described in the present invention, the switching valve includes a cavity connected to the two fixed ends of the multi-stage telescopic gas rod, and two symmetrical branch pipes are arranged on the outside of the cavity, and the end of each branch pipe is provided with an outlet on the upper surface of the fixed plate, each outlet corresponds to a sealing cover, and any outlet is connected to the hose.

[0012] As a preferred solution of the adjustable ventilation floor driven by high expansion alloy described in the present invention, a valve body is arranged in the cavity, a connecting channel is arranged on the valve body, and the valve body can be rotated to adjust the direction of the connecting channel to connect the corresponding branch pipe with the multi-stage telescopic gas rod 2.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0036] Example 1

[0037] Reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides an adjustable ventilated floor driven by a high expansion alloy, including a floor assembly 100, which includes a bracket 101 and a fixed plate 102 mounted on the bracket 101, a movable plate 103 is slidably arranged along the lower surface of the fixed plate 102, and a pneumatic member 104 is arranged between the movable plate 103 and the fixed plate 102, and the pneumatic member 104 pushes the movable plate 103 to slide, and adjusts the misalignment area of ​​the through holes on the movable plate 103 and the fixed plate 102; a temperature sensing assembly 200, including a shell 201 suspended on the chassis, a high expansion alloy strip 202 is arranged inside the shell 201, and the high expansion alloy strip 202 is arranged in the shape of an Archimedean spiral, and a plurality of guide rollers 203 arranged in a spiral line are arranged on the outside of the high expansion alloy strip 202, which are used to limit the expansion and contraction direction of the high expansion alloy strip 202, and a multi-stage telescopic gas rod 204 is arranged at the end of the high expansion alloy strip 202, and the multi-stage telescopic gas rod 204 is connected to the pneumatic part 104 through a hose 205.

[0038] In order to achieve automatic adjustment of the ventilated floor without the need for additional electricity or cable connections, a purely mechanical control solution based on high expansion alloy strips 202 was designed. Specifically, a high expansion alloy strip 202 is set near the heating point of the machine room for temperature sensing. When the temperature rises, the high expansion alloy strip 202 will extend. Since the high expansion alloy strip 202 is limited by multiple guide rollers 203 around it, it can only extend and retract at its end, thereby pushing the multi-stage telescopic gas rod 1 204 to extend and retract. The multi-stage telescopic gas rod 1 204 is connected to the branch pipe 104c of the pneumatic part 104 through the hose 205. Therefore, the change of internal gas will push the piston 104c-2 inside the branch pipe 104c to move. The branch pipe 104c is connected to the multi-stage telescopic gas rod 2 104a through the switching valve 104b, thereby pushing the multi-stage telescopic gas rod 2 104a to extend and retract. Finally, by pushing the sliding foot 103a of the movable plate 103 to slide in the sliding groove 102a of the fixed plate 102, the position between the movable plate 103 and the fixed plate 102 is adjusted, and then the offset area of ​​the through holes of the two is adjusted, thereby realizing automatic control of the ventilation volume.

[0039] This purely mechanical control solution has the following advantages: Energy saving and environmental protection: Since no electricity or cable connection is required, energy consumption and wiring costs are reduced. Simplified structure: Through the linkage between mechanical components, the overall structure is simplified and the maintenance complexity is reduced. Adaptive adjustment: The adjustable switching valve 104b is set to adaptively adjust the moving speed of the moving plate 103, ensuring the smoothness of the ventilation volume adjustment.

[0040] Furthermore, an adjustable cavity 104b-3a is provided in the switching valve 104b: a cavity 104b-3a is provided inside the valve body 104b-2, and the change of the cavity 104b-3a can be controlled. When the multi-stage telescopic gas rod 1 204 changes in a large range, excess gas is accommodated by the cavity 104b-3a, while the change range of the multi-stage telescopic gas rod 2 104a is smaller, thereby ensuring that the spacing adjustment between the movable plate 103 and the fixed plate 102 is more precise and stable, and can better adapt to different temperatures and scenes, thereby increasing scalability.

[0041] Example 2

[0042] Reference Figure 3-Figure 8 , which is the second embodiment of the present invention, is different from the first embodiment in that: two pneumatic parts 104 are provided, and are symmetrically arranged at the two sides of the fixed plate 102. Each pneumatic part 104 is provided with two symmetrical branch pipes 104c on the outside of the cavity 104b-1, and the end of each branch pipe 104c is provided with an outlet on the upper surface of the fixed plate 102, each outlet corresponds to a cover, and any outlet is connected to the hose 205.

[0043] Four outlets are designed at the four corners of the upper surface of the fixed plate 102. These outlets are used to connect the temperature sensing component 200. Specifically, when the temperature sensing component 200 (i.e., the high thermal expansion alloy strip) is close to a certain corner, the cover at the corner is opened, and the hose of the temperature sensing component 200 is connected to the outlet. Then, by rotating the switching valve 104b, the branch pipe 104c corresponding to the outlet is connected to the multi-stage telescopic gas rod 104a. In this way, the temperature sensing component 200 can transmit the temperature change signal to the corresponding multi-stage telescopic gas rod 104a through the hose 205, the outlet and the branch pipe 104c. When the multi-stage telescopic gas rod 104a is extended and retracted due to temperature changes, since the other multi-stage telescopic gas rod 104a is fixed on the other side of the moving plate 103, it also undergoes corresponding adaptive changes. In short, different branch pipes 104c can be selected according to the location of the temperature sensing component 200. This design allows the system to flexibly adjust the path according to actual needs, ensuring the transmission efficiency while also improving the adaptability of the system.

[0044] The pneumatic part 104 includes a second multi-stage telescopic gas rod 104a and a switching valve 104b, wherein the free end of the second multi-stage telescopic gas rod 104a is fixed to the side of the sliding foot 103a, and the fixed end of the second multi-stage telescopic gas rod 104a is connected to the switching valve 104b. The switching valve 104b includes a cavity 104b-1 connected to the fixed end of the multi-stage telescopic gas rod 104a, and a valve body 104b-2 is arranged in the cavity 104b-1. A connecting channel 104b-3 is arranged on the valve body 104b-2. The valve body 104b-2 can be rotated to adjust the direction of the connecting channel 104b-3, connecting the corresponding branch pipeline 104c with the multi-stage telescopic gas rod 104a, and a slide groove 102a is provided on the lower surface of the fixed plate 102, and a sliding foot 103a is provided on the upper surface of the movable plate 103. The sliding foot 103a slides in the slide groove 102a, and the pneumatic part 104 is located on the side of the slide groove 102a. The branch pipeline 104c includes a channel body 104c-1 and a piston 104c-2 sliding along the channel body 104c-1. The volume of the channel body 104c-1 is greater than the volume of the multi-stage telescopic gas rod 1 204 and the multi-stage telescopic gas rod 2 104a.

[0045] An adjustable switching valve 104b is provided, and the switching valve 104b controls the ventilation speed between the branch pipe 104c and the multi-stage telescopic gas rod, and the moving speed of the moving plate 103 can be adaptively adjusted. Since the valve body 104b-2 is provided with a cavity 104b-3a, the change of the cavity 104b-3a can also be controlled, and since the capacity of the branch pipe 104c is greater than the capacity of the multi-stage telescopic gas rod 1 204 and the multi-stage telescopic gas rod 2 104a, when the multi-stage telescopic gas cylinder changes in a large range, the excess gas is accommodated by the cavity 104b-3a, and the multi-stage telescopic gas rod 2 104a changes in a small range to adapt to the passing distance between the moving plate 103 and the fixed plate 102.

[0046] The connecting passage 104b-3 includes a containing cavity 104b-3a arranged in the valve body 104b-2, and two strip grooves 104b-3b are provided on the outer wall of the valve body 104b-2, one of the strip grooves 104b-3b corresponds to the fixed end of the multi-stage telescopic rod 2, and the other strip groove 104b-3b is connected to any branch pipe 104c, and a self-locking member 104b-4 is arranged inside the valve body 104b-2, and the self-locking member 104b-4 is located above the containing cavity 104b-3a.

[0047] It should be noted that the self-locking member 104b-4 is used to lock the height and angle of the valve body 104b-2 in the cavity 104b-1 (that is, to lock the adjusted position of the valve body 104b-2). Specifically, a cavity is set in the upper half of the valve body 104b-2, and a plurality of retractable and movable extrusion blocks are set in the cavity. A conical block is set below the extrusion block, and a spring is set at the bottom of the conical block. The conical block is pushed upward by the spring, and the conical block drives each extrusion block to move outward. The extrusion block moves outward to support the inner wall of the cavity 104b-1, thereby locking the position of the valve body 104b-2. A button is set on the top of the conical block, and a groove is opened on the upper surface of the fixed plate 102. The upper end of the button is located in the groove and does not exceed the upper surface of the groove. In this way, the self-locking member 104b-4 can be unlocked by pressing the button downward, and the self-locking member 104b-4 can be locked by releasing the hand.

[0048] It should also be noted that three strip grooves 104b-3b are arranged in an annular shape on the outer wall of the valve body 104b-2, one of the strip grooves 104b-3b corresponds to the fixed end of the multi-stage telescopic gas rod 104a, and the other two strip grooves 104b-3b are connected to any one of the two branch pipes 104c. In this way, the branch pipe 104c can be connected to the multi-stage telescopic gas rod 104a through the strip groove 104b-3b, thereby connecting the gas circuits in series, ensuring that the high expansion alloy strip 202 drives the multi-stage telescopic gas rod 104a to extend and retract. This step is achieved by rotating the valve body 104b-2. Furthermore, by adjusting the height of the valve body 104b-2 in the cavity 104b-1, when the valve body 104b-2 goes deeper into the cavity 104b-1, the volume chamber 104b-3a becomes smaller, so that less gas can be contained, so that the change ratio between the multi-stage telescopic gas rod 1 204 and the multi-stage telescopic gas rod 2 104a becomes closer and the changes become more synchronized.

[0049] In this embodiment, the high expansion alloy strip 202 is temperature-sensitive. When the temperature is high, the high expansion alloy strip 202 expands and contracts at the end, thereby pushing the multi-stage telescopic gas rod 204 to expand and contract. Since the multi-stage telescopic gas rod 204 is connected to the branch pipe 104c of the pneumatic part 104 through the hose 205, the gas inside the multi-stage telescopic gas rod 204 pushes the piston 104c-2 inside the branch pipe 104c to move. Since the branch pipe 104c is connected to the multi-stage telescopic gas rod 104a through the switching valve 104b, the multi-stage telescopic gas rod 104a is pushed to expand and contract, thereby pushing the sliding foot 103a of the movable plate 103 to slide in the sliding groove 102a of the fixed plate 102, thereby realizing the position adjustment between the movable plate 103 and the fixed plate 102, and then adjusting the misaligned area of ​​the through holes of the two, thereby realizing automatic control of the ventilation volume.

[0050] The remaining structures are the same as those of Example 1.

[0051] Example 3

[0052] Reference Figure 1-Figure 3 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the temperature sensing component 200 includes a shell 201 suspended on the chassis, a high expansion alloy strip 202 is arranged inside the shell 201, and the high expansion alloy strip 202 is arranged in the shape of an Archimedean spiral, and a plurality of guide rollers 203 arranged in a spiral line are arranged outside the high expansion alloy strip 202 to limit the expansion and contraction direction of the high expansion alloy strip 202, and a multi-stage telescopic gas rod 204 is arranged at the end of the high expansion alloy strip 202, and the multi-stage telescopic gas rod 204 is connected to the pneumatic part 104 through a hose 205. The shell 201 is set to be circular, and one of the side surfaces is set to be open, and the side surface is set to face the ventilation hole of the chassis or the heating place.

[0053] Among them, one side of the shell 201 is set to be open and face the heat-generating part of the chassis, so that the high expansion alloy strip 202 can effectively sense the temperature change inside the chassis. And respond to expansion and contraction in time. A number of guide rollers 203 are set on both sides of the high expansion alloy strip 202. The high expansion alloy strip 202 is clamped and limited by the multiple guide rollers 203 on both sides to ensure that when the high expansion alloy strip 202 expands or contracts, changes only occur at the end, so that it can be felt by the multi-stage telescopic gas rod 204 set at its end, and directly fed back through the changes of the multi-stage telescopic gas rod 204. The multi-stage telescopic gas rod is connected to the pneumatic part 104 through a hose 205, so that the two are softly connected, so that the temperature sensing component 200 and the floor component 100 are each independent to a certain extent, so that the temperature sensing component 200 can be set anywhere.

[0054] The high expansion alloy strip 202 is one of the key components in the ventilation floor automatic adjustment system. It is used to sense the temperature changes in the machine room and drive the subsequent mechanical actions through its own thermal expansion effect. In order to ensure good thermal expansion performance and mechanical strength, a variety of high expansion alloy materials can be selected. The following are several commonly used high expansion alloys and their characteristics: (1) Cu60Zn40 alloy: This is a brass alloy composed of 60% copper (Cu) and 40% zinc (Zn). It has a high linear expansion coefficient, which is about 19×10 -6 / ℃. This alloy has good processing properties and a high thermal expansion coefficient, and is suitable for applications that require a large thermal expansion effect. (2) FeNi22Cr3 alloy: This is an iron-nickel-chromium alloy containing about 22% nickel (Ni), 3% chromium (Cr) and the remainder iron (Fe). Its linear expansion coefficient is about 18.5×10 in the temperature range of 20 to 100℃. -6 / ℃. This alloy not only has a high thermal expansion coefficient, but also has good strength and corrosion resistance. (3) FeNi20Mn6 alloy: This is an iron-nickel-manganese alloy containing about 20% nickel (Ni) and 6% manganese (Mn), with the remainder being iron (Fe). Its linear expansion coefficient is about 21×10 in the temperature range of 20 to 100℃. -6 / ℃. This alloy also has a high coefficient of thermal expansion and good mechanical properties. (4) FeNi13Mn7 alloy: This is an iron-nickel-manganese alloy containing about 13% nickel (Ni) and 7% manganese (Mn), with the remainder being iron (Fe). Its linear expansion coefficient is about 21×10 -6 / ℃. This alloy has a high thermal expansion coefficient and good processing properties. (5) Mn72Cr18Ni10 alloy: This is a manganese-chromium-nickel alloy containing about 72% manganese (Mn), 18% chromium (Cr) and 10% nickel (Ni). Its linear expansion coefficient is about 26×10 in the temperature range of 20 to 100℃. -6 / ℃. This alloy has a very high coefficient of thermal expansion and is suitable for applications where large thermal expansion is required.

[0055] The high expansion alloy strip 202 is one of the core components of the ventilation floor automatic adjustment system, which is used to sense the temperature change in the machine room and drive the subsequent mechanical action through its own thermal expansion effect. Cu60Zn40 alloy, FeNi22Cr3 alloy, FeNi20Mn6 alloy, FeNi13Mn7 alloy and Mn72Cr18Ni10 alloy are selected as the material of the high expansion alloy strip 202 because these alloys have a high thermal expansion coefficient and can meet the requirements of the ventilation floor automatic adjustment system.

[0056] In this embodiment, a high expansion alloy strip 202 is arranged near the heating part of the chassis for temperature sensing. When the temperature is high, the high expansion alloy strip 202 extends. Since the high expansion alloy strip 202 is limited by multiple guide rollers 203 around it, it can only be extended and retracted at the end, and thus can only push the multi-stage telescopic gas rod 204 to extend and retract. Since the multi-stage telescopic gas rod 204 is connected to the branch pipe 104c of the pneumatic part 104 through a hose, the gas inside the multi-stage telescopic gas rod 204 pushes the piston 104c-2 inside the branch pipe 104c to move, and then the multi-stage telescopic gas rod 2 104a is driven to extend and retract through the pneumatic part 104, thereby adjusting the misalignment area of ​​the through hole between the movable plate 103 and the fixed plate 102.

[0057] The remaining structure is the same as that of Example 2.
