It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, a server cabinet 10 with heat dissipation by air suction includes a cabinet body 20 and a heat dissipation device 30 with air suction.
As shown in fig. 1, the cabinet body 20 is provided with an air inlet (not shown) and an air outlet 210.
As shown in fig. 1, the air suction and heat radiation device 30 includes a blower 310 and a blowing duct 320 communicating with the blower 310. The air supply duct 320 has an air inlet 321 and an air outlet 322. The air inlet 321 of the air supply duct 320 communicates with the air supply outlet 311 of the blower 310. The blower 310 blows fast flowing air (i.e., wind) into the air supply duct 320, so that the air supply duct 320 receives wind blown from the air inlet 321 to the air outlet 322.
As shown in fig. 1 and 3, the air supply duct 320 is further opened with a communication port 323, and the communication port 323 of the air supply duct 320 communicates with the air outlet 210 of the cabinet body 20.
As shown in fig. 3, a variable pressure nozzle 324 is provided in the blast duct 320. The variable pressure nozzle has an inlet end 325 and an outlet end 326. The pressure swing nozzle 324 tapers from an inlet end 325 and an outlet end 326 toward the middle. The variable pressure nozzle 324 is disposed between the air inlet 321 and the communication port 323 of the air supply duct 320, and extends at least beyond the center of the communication port 323 in a direction away from the air inlet 321. After the wind in the air supply pipeline 320 enters the air inlet end 325 of the variable pressure nozzle 324, the variable pressure nozzle 324 is gradually narrowed, so that the air pressure of the wind is increased, and the moving speed of the wind is greatly increased.
As shown in fig. 2, the wind pressurized and accelerated by the air inlet 325 of the pressure swing nozzle 324 is ejected at high speed from the air outlet 326 of the pressure swing nozzle 324. Since the pressure swing nozzle 324 narrows from the air outlet end 326 to the middle (i.e., the pressure swing nozzle 324 gradually widens from the middle to the air outlet end 326), the pressure-increased and speed-increased air is discharged from the air outlet end 326 of the pressure swing nozzle 324 at a high speed to achieve pressure reduction. Thus, a relatively low pressure is formed in the region near the air outlet end 326, and a relatively high pressure is formed in the cabinet body 20. Due to the characteristic of air flowing from high pressure to low pressure, air within cabinet body 20 flows toward air outlet end 326. That is, an air suction phenomenon occurs in which air in the cabinet body 20 is sucked into the air blowing duct 320.
As shown in fig. 3, it should be noted that the pressure-varying nozzle 324 is disposed between the air inlet 321 and the communication port 323 of the air supply duct 320, and extends to a direction away from the air inlet 321 at least to a position beyond the center of the communication port 323, i.e., the air outlet 325 of the pressure-varying nozzle 324 must extend to a position beyond the center of the communication port 323 to prevent wind from being ejected from the air outlet 326 into the cabinet body 20 too early.
As shown in fig. 1, the number of the cabinet bodies 20 is plural, and the plural cabinet bodies 20 are arranged in a straight line in close proximity to each other. The air suction and heat dissipation device 30 can simultaneously suck air and dissipate heat of the cabinet bodies 20, so that the cost is low and the occupied space is small. The number of the pressure changing nozzles 324 is the same as the number of the cabinet bodies 20, and the pressure changing nozzles 324 correspond to the cabinet bodies 20 one to one.
As shown in fig. 1 and 3, the air supply duct 320 is a docking type air supply duct. The air supply duct includes one or more sections of air supply pipes 327, and the air supply pipes 327 are opened with the communication ports 323. One embodiment of the invention is as follows: the adjacent two blast pipes 327 are connected by screwing. Another embodiment of the present invention is: two adjacent blast pipes 327 are connected by interference fit. Of course, the connection method of the adjacent two air blowing pipes 327 according to the present invention is not limited to the screw connection method and the interference fit method. The present invention can connect the corresponding number of the blast pipes 327 according to the number of the cabinet bodies 20, thereby avoiding the waste of materials and being beneficial to reducing the cost. And the connection mode is simple to operate and convenient to transport.
As shown in fig. 3, one embodiment of the present invention is: the variable pressure nozzle 324 is adhered to the blast pipe 327. Of course, the variable pressure nozzle 324 may be disposed in the air supply pipe 327 by welding or fastening.
As shown in fig. 1, the air outlet 210 of the cabinet body 20 is opened at the bottom of the cabinet body 20, and the air inlet of the cabinet body is opened at the top of the cabinet body 20. The air outside the cabinet body 20 enters the cabinet body 20 from the air inlet at the top of the cabinet body 20, flows from the top of the cabinet body 20 to the bottom of the cabinet body 20, flows from the air outlet 210 at the bottom of the cabinet body 20 to the air supply pipeline 320, and flows through the whole cabinet body 20, so that the cabinet body 20 has uniform heat dissipation, high heat dissipation efficiency and good effect.
The working principle of the air suction heat dissipation type server cabinet 10 of the invention is as follows:
the blower 310 blows fast flowing air (i.e., wind) into the air supply duct 320, so that the air supply duct 320 receives wind blown from the air inlet 321 of the air supply duct 320 to the air outlet 322 of the air supply duct 320. After the wind reaches the air inlet 325 of the variable pressure nozzle 324 in the flowing process of the air supply pipeline 320, the variable pressure nozzle 324 is gradually narrowed, so that the air pressure of the wind is increased, and the moving speed of the wind is greatly increased. The wind pressurized and accelerated by the air inlet 325 of the pressure swing nozzle 324 is ejected out of the air outlet 326 of the pressure swing nozzle 324 at high speed. Because the variable pressure nozzle 324 narrows from the air outlet end 326 to the middle, the pressure reduction is realized when the pressurized and accelerated wind is ejected from the air outlet end 326 of the variable pressure nozzle 324 at high speed. Thus, a relatively low pressure is formed in the region near the air outlet 326, and a relatively high pressure is formed in the cabinet body 20. Therefore, the air in the cabinet main body 20 flows to the air outlet end of the variable pressure nozzle 324, joins the air ejected from the variable pressure nozzle 324 in the vicinity of the air outlet end, and the air flowing from the cabinet main body 20 to the air blowing duct 320 joins the air ejected from the variable pressure nozzle 324 and is then blown to the air outlet 322 of the air blowing duct 320. The air in the cabinet body 20 carries the heat generated by the cabinet body 20, and the air in the cabinet body 20 flows to the air supply duct 320 and brings the heat in the cabinet body 320 out, so that the heat dissipation of the server cabinet 10 is realized.
The air suction heat dissipation type server cabinet 10 provided by the invention has the advantages of small cabinet volume, high integration and low cost.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
