Abstract

The invention relates to a novel silent case, which belongs to the second generation product of silent case and is applied in the field of computer, communication, instrument and meter, and mechatronics. The novel silent case is characterized in that an open water tank is mounted below a top plate of the silent case; a fan is embedded in the open end of the water tank; the water level in the water tank is slightly lower than the fan; the water tank is reliably connected with a heat generating part through a middle part; most of heat generated by the heat generating part is evaporated by the fan blowing water, so that the thermal equilibrium temperature is very close to the ambient environment, thereby obtaining good heat radiation effect. The fan is controlled by a manual switch mounted on the panel and a temperature control switch mounted on each heat generating part in parallel, and is powered by a main board or a power adapter; and the silent case also includes a DC (direct current) interface mounted on a rear plate to realize power supply of a switch power source to a liquid crystal display.

Description

New quiet case

Technical field

The present invention is a new quiet case, belongs to quiet case second generation product, is applied to computing machine, communication, instrument and meter, electromechanical integration field.

Background technology

Computing machine, communication, instrument and meter, electromechanical integration field; The capital is used some high performance components and is constituted complicated functional circuit; Thereby reach certain purpose, and good heat radiation is the necessary condition that guarantees these high performance components operate as normal, at present with fan blowing cooling be air-cooled be the cooling method of popularizing the most; But what supervene is noise and contamination by dust problem, and cabinet must be reserved louvre; It is uncomfortable that fan noise can make us, and influences its stability and reliability thereby dust can pollute functional circuit, can reduce air-cooled radiating effect simultaneously.Though propose first generation quiet case in 2009102588144 patents of my application; Adopt top water tank evaporative heat loss to remove fan; Noise, contamination by dust and cabinet sealing problem have been solved; But housing temperature can be apparently higher than wind-cooling heat dissipating, make all users feel uneasy: can or can not burn out high performance components, can or can not the too high stability that influences functional circuit of temperature or the like query; Simultaneously because liquid cooling heat radiation system very complicacy take up space very much, cost is also higher, big cabinet ability.

Summary of the invention

The present invention proposes a cover optimizing design scheme for solving the shortcoming that equilibrium temperature is higher in 2009102588144 patents, liquid cooling heat radiation system is complicated and expensive.

Objects and advantages of the present invention, provide a kind of be superior to 2009102588144 patents and the cabinet equilibrium temperature is controlled, than the cheap and simple second generation quiet case of liquid cooling heat radiation system.

For realizing above-mentioned purpose, the present invention adopts following technical scheme: with a uncovered water tank, reliably be connected with heat generating member through middlewares such as heat-conducting plates; Water tank closely contacts with the cabinet top board, water tank is uncovered be embedded in one be fixed on top board below band cover small fan, be the circular hole on the top board over against the fan top; Water tank is to be processed by the high thermal conductivity metal material, is added with water in the case, and the water surface and small fan keep the spacing of 10mm; The heat that heat generating member produces passes to water tank through heat-conducting plate; Water in the case absorbs heat and temperature rise, and heat also can conduct to cabinet panel, and fan blows water and can cause evaporating acceleration and take away a large amount of heat; Thereby draw to equilibrium temperature, this invention is more suitable for more powerful heat generating member.

1U blade chassis

32, and 30 32 is to be processed by the high thermal conductivity metal material with all; Framework 30, top are large water tanks, and water tank has a water injection hole 33 and four fan mouths, and the fan of a band cover 2 is installed on each fan mouth, and fan is supplied power by Switching Power Supply; In the middle of the large water tank is the heat radiation window of a hollow, and the heat radiation window faces the fan guard of ten 1U blade chassis.See Fig. 8 and 9, empty van is the framework 30 fronts two rows fixed orifices that distributing, and is used for fixing ten 1U blade chassis, and 30 both sides are fixed heads, and dashing on each fixed head has three preformed holes; Empty van is that distributing two AC sockets 35 and the

AC socket

36,35 of framework 30 back sides connects external power source, and 36 connect ten blade servers.See Figure 10, this 1U blade chassis is made up of top cover 3 and under

casing

31, and 3 and 31 is to be processed by the high thermal conductivity metal material; Top cover 3 has the corresponding of four holes and water tank 5 extension boards; Be distributed with power supply position, support 15, water tank 5 and mainboard position in the under casing 31; 15 internal fixation hard disks; There is the fixedly fixed leg 17 of mainboard the mainboard position, and water tank 5 is close to 31 base plates and is fixed on framework 31 side plates, 5 be close to 31 side plates face one rectangular opening is arranged; The fan of the embedded band cover 2 of rectangular opening, fan is fixed on 31 side plates; Two heat-conducting blocks 7, side respectively have a temperature detect switch (TDS) 19, link to each other with fan, and the switch of control fan, the hole of two tapping is respectively arranged at the top, is installed under water tank 5 extension boards, and heat-conducting block 7 also is close to CPU and mainboard is fixed; 5,7 all is to be processed by the high thermal conductivity metal material; Framework 31 front panels have start and SR 11, the LED16 that also have three indication starts, HDD, resets, and framework 31 backboards have an AC power supplies socket 35 and a

DC interface

20,35 extended lines to be connected with the prefix switch power supply, and 20 export with Switching Power Supply+12V and to link to each other.

1U power supply and hard disk, mainboard are installed in the 1U blade chassis, heat-conducting block 7 are close to CPU and mainboard is fixed, on the water tank 5 embedded fan stuck-at-U blade side plates; The position, hole of 5 extension board and heat-conducting block 7 is relative; Connect good interconnector, connect temperature detect switch (TDS) 19 and fan, Switching Power Supply, with the top cover 3 that closes; Combine as a whole 3,5,7 with screw, surface of contact is coated heat-conducting silicone grease; The 1U blade is edge-on, the fan mouth is arranged up, pour water in water tank 5 through the fan page or leaf; The water surface gets final product from fan 10～15mm, and the 1U blade is inserted framework 31, and fan guard is over against the heat radiation window 34 of framework 31; Fix the 1U blade, the AC socket is communicated with the 1U blade server with power lead.Successively ten 1U blades are connected energising.Add water to framework 31 water tanks through water filling port 33, the water surface get final product from fan 10～15mm, is that framework 31 fans are supplied power by power supply adaptor independently.Start ten 1U blades successively.For ten 1U blades, the heat that power supply, hard disk produce, a part is by 1U blade chassis guide frame 31; And the heat that CPU produces can be absorbed heat and heated up by the water in the heat-conducting block 7 guiding
