Description

Technical Field

[0001] The utility model relates to the technical field of fluid dynamics, in particular to a chimney-type hot channel sealing component. Background Art

[0002] The chimney-style hot aisle containment assembly is an efficient heat dissipation system for server rooms. Its design is inspired by the traditional chimney structure, but is more complex and engineered in function. This design is designed to exhaust hot air from the cabinet through a vertical hot aisle to improve heat dissipation efficiency and optimize air flow.

[0003] At present, most of the existing chimney-type hot channel containment components adopt a fixed installation method, with a fan installed at the top or bottom. The fan is operated to achieve the effect of heat dissipation and exhaust. However, the heat source generated in the narrow gap between the hardware is blocked by the hardware above and below and cannot be effectively discharged to the outside, causing the hardware to continue to heat up and make the hardware vulnerable to damage. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a chimney-type heat channel sealing component, which has the advantages of being able to effectively and quickly dissipate heat and cool down the heat source in the narrow space between hardware. It solves the problem that the current method of using a fixed fan installed inside to dissipate heat inside the cabinet cannot quickly and effectively dissipate heat and cool down the heat source generated in the narrow space of the hardware.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chimney-type hot channel sealing component, comprising a bracket component, a support rod component and a heat exhaust component, the bracket component comprising a hot channel bracket, a lower ventilation plate and an upper ventilation plate are fixed at the upper and lower positions of the hot channel bracket, and a lower fan is fixed on the lower ventilation plate, and an upper fan is fixed on the bottom of the upper ventilation plate. The chimney-type hot channel sealing component is used in industrial equipment or combustion systems to control heat transfer and smoke emission. The lower fan is operated to allow outside air to enter the hot channel bracket from the lower ventilation plate, and after cooling the interior, the upper fan is operated to discharge the internal gas from the upper ventilation plate.

[0006] The support rod assembly includes a support rod movably hinged between the lower fan and the upper fan, support rods are fixed at the four corresponding corners of the opposite sides of the lower and upper fans, and an exhaust fan is movably sleeved on the two support rods at each end. The support rod is used to stabilize the exhaust fan to prevent the exhaust fan from shaking when it moves.

[0007] The heat exhaust component includes a first exhaust fan and a second exhaust fan which are threadedly connected to the support rod. The exhaust fan is on the side of the support rod and slides up and down along its length direction to achieve the effect of heat dissipation for the heat source in the hot channel bracket. The air is discharged to the outside through the first exhaust fan, and the air is drawn out through the second exhaust fan. After the cold air is sent into the hot channel bracket, the interior is cooled down. The internal gas is drawn out to the outside through exhaust, so as to achieve the effect of sufficient heat dissipation and cooling of the interior.

[0008] When the chimney-type hot channel air-sealing component is used and the internal heat dissipation and cooling are carried out, after the temperature in the hot channel closed component is raised, the lower fan and the upper fan are controlled to operate. At this time, the lower fan transports the outside air inward, mixes and cools the internal heat source, and then operates the upper fan to output the internal gas to the outside to achieve ventilation and cooling. At the same time, the operation of the driving motors at both ends is controlled so that the output end drives the support rod to rotate. At this time, under the force of the threaded connection between the side of the support rod and the connecting hole, the ventilation interfaces of the lower and second exhaust fans are relative, and then the output ends of the driving motors at both ends are controlled to rotate synchronously in the same direction clockwise or counterclockwise, so that the two exhaust fans move up and down at the same time, and the gas is blown inward by the first exhaust fan, and the internal gas is extracted outward by the second exhaust fan to complete the sufficient heat dissipation and cooling work. After completion, all equipment is controlled to stop operation, so that the first exhaust fan and the second exhaust fan return to their initial positions.

[0009] As a further improvement of the above scheme, the down fan and the up fan are both provided with installation interfaces, and the first and second exhaust fans are provided with connection interfaces, a connecting piece is fixed in the connection interface, a connecting pipe is fixed in the connecting piece, and one end of the connecting pipe is fixed in the installation interface.

[0010] Through the above technical solution, the connecting pipe is specifically a flexible and foldable connecting pipe, so that when the first and second exhaust fans move up and down, the connecting pipe can freely expand and contract according to the height.

[0011] As a further improvement of the above solution, the first and second exhaust fans are both provided with connection holes, and the support rods are threadedly connected in the connection holes.

[0012] Through the above technical solution, when the support rod rotates clockwise or counterclockwise, under the force of the threaded connection with the connecting hole, the first and second exhaust fans move up and down to adjust the height.

[0013] As a further improvement of the above solution, the sides of the first and second exhaust fans are both provided with ventilation interfaces that communicate with the connection interface.

[0014] Through the above technical solution, the ventilation interface and the connection interface are vertically arranged, so that the first and second exhaust fans can transport gas into the hot channel bracket and exhaust gas to the outside when moving up and down.

[0015] As a further improvement of the above solution, an air-blocking plate is movably sleeved in the installation interface, and a rubber side plate is fixed to the side of the air-blocking plate and fits against the inner side of the connecting piece.

[0016] Through the above technical solution, the air-blocking plate is used to seal the installation interface to prevent gas from being output from the installation interface when the lower and upper fans operate independently. After the air-blocking plate is subjected to force, it moves downward, so that the gas supply channel of the installation interface is opened, thereby achieving the effect of conveying gas.

[0017] As a further improvement of the above solution, a telescopic rod is fixed on the air-sealing plate, and the telescopic rod is movably sleeved in the installation interface.

[0018] Through the above technical solution, a circular hole is opened in the installation interface at a position corresponding to the telescopic rod, and the telescopic rod is movably sleeved in the circular hole, thereby improving the stability of the air-blocking plate moving up and down.

[0019] As a further improvement of the above solution, a tension spring is movably sleeved on the side of the telescopic rod, and both ends of the tension spring are fixed in the installation interface and on the air-sealing plate.

[0020] Through the above technical solution, the tension spring has the function of pulling the air-blocking plate upward, so that the air-blocking plate fits in the installation interface, thereby achieving the function of sealing the interface.

[0021] As a further improvement of the above solution, a driving motor is fixed to the bottom of the lower fan, and the output end of the driving motor passes through the lower fan and is fixed to one end of the supporting rod.

[0022] Through the above technical solution, a driving motor is installed at the bottom of each of the four support rods, and the two driving motors at both ends operate synchronously. During operation, the first and second exhaust fans connected to the side can be moved up and down.

[0023] As a further improvement of the above scheme, the side of the support rod is movably sleeved with a limiting ring, the limiting ring is affixed to the first and second exhaust fans, the side of the limiting ring is threadedly connected with a locking screw, and at the same time a limiting hole is opened on the side of the support rod, the output end of the locking screw passes through the limiting ring and is inserted into the limiting hole.

[0024] Through the above technical solution, the limit ring is used to limit the upper and lower movable heights of the first and second exhaust fans. By rotating the locking screw counterclockwise, the front end is disengaged from the limit hole. At this time, the height of the limit ring can be adjusted, and then the locking screw is rotated counterclockwise to insert the front end into the limit ring at the corresponding position, thereby achieving the function of adjusting the restricted height.

[0025] As a further improvement of the above solution, a push rod is fixed to one end of the connecting pipe, and one end of the push rod is attached to the air-sealing plate.

[0026] Through the above technical solution, when the bottom end of the connecting pipe is installed with the installation interface, the top rod pushes the air-blocking plate downward, so that the air-blocking plate moves downward and the installation interface is opened, thereby achieving the effect of intercommunication. When the lower and upper fans are operating, part of the gas can be transported through the connecting pipe.

[0027] Compared with the prior art, the utility model provides a chimney-type hot channel sealing component, which has the following beneficial effects:

[0028] 1. The chimney-type hot channel sealing component is equipped with lower and upper fans correspondingly installed between the lower and upper ventilation plates in the hot channel bracket. The lower fan supplies air inwards, while the upper fan draws air outwards, so as to replace the airflow in the cabinet and reduce the overall temperature in the cabinet.

[0029] 2. The chimney-type heat channel sealing component is respectively connected with the first and second exhaust fans through the support rods at both ends, and the exhaust fans are connected to the installation interfaces of the corresponding fans through connecting pipes. Therefore, when the lower fan is operating, part of the gas is input into the first exhaust fan through the connecting pipe. While the first exhaust fan moves up and down on the side of the support rod, the air is blown between the hardware, and the second exhaust fan is controlled to operate synchronously with the first exhaust fan. When the upper fan is operating, the second exhaust fan absorbs the blown heat source inside and discharges it through the upper fan, thereby effectively achieving the effect of heat dissipation treatment for the heat source in the narrow space of the hardware.
