Description
Technical field
The utility model belongs to heat exchange of heat pipe field, more particularly between heat exchange of heat pipe cold side medium and hot side medium
The sealing structure of partition board.
Background technology
Heat pipe is a kind of heat transfer element with high heat-transfer performance, it passes through the phase transformation of working media in airtight vacuum shell
Latent heat transmits heat, it has heat-transfer capability big, heat transfer efficiency high feature.
Typical gravity assisted heat pipe is as shown in Figure 1.Heat exchange of heat pipe is generally made of more heat pipes, high with heat transfer efficiency,
A variety of advantages such as drag losses are small, compact-sized, reliable operation and maintenance cost are few, space technology, electronics, metallurgy, power,
The various industries such as oil, chemical industry, which are obtained for, to be widely applied.
Heat exchange of heat pipe is mainly made of components such as shell, heat-pipe elements and cold and hot fluid spacing boards.Equipment lower part is heat
Fluid channel, top are cold fluid pass, and centre is separated by partition board.The quality of heat pipe by membrane support, meanwhile, heat pipe is in partition board
Position sets support and sealing structure, plays the buffer action between support heat pipe and cold and hot fluid.For heat exchange of heat pipe, the sealing
If structure is in the process of running it cannot be guaranteed that sealing effect, occurs crossfire between cold and hot fluid, then system thermal efficiency declines, energy
Consumption rises, the serious safe operation that can influence system.
In addition, after heat exchange of heat pipe long-play, the heat transfer effect of heat pipe can be declined, and heat-pipe elements are needed replacing
To solve the problems, such as this.Therefore, heat pipe sealing structure should have the operable of more heat exchanger tube under the premise of ensuring sealing effect
Property.
For heat exchange of heat pipe, common heat pipe sealing structure has following several：
1. heat pipe standoff block is welded with partition board, weld seam is sealing structure.
Advantage：Sealed reliable；Disadvantage：Heat pipe can not be replaced.
2. heat pipe standoff and sealing element are combined with partition board using steel-steel sealing, filler/sealing ring sealing, or both, close
Weight, spring or pressing plate of the pressing force from heat pipe at envelope.Gap is relied primarily on for the sealing between sealing element and partition board hole
Pressing force of the interior sealing material to metal surface.
Advantage：Heat pipe can be replaced；Disadvantage：Sealing effect and spring selection appropriate level, heat pipe length dimension deviation,
Pressing plate pressing force size, partition board deformation extent, transport is jolted etc., and factors are related, and sealing performance is not sufficiently stable.
3. heat pipe standoff and sealing 1.1 use screw thread pair+bead seal arrangement with partition board, by rotating heat pipe band dynamic sealing
Part rotates, compress gasket, to meet seal request.；
Advantage：Heat pipe can be replaced；Disadvantage：Partition board hole sets internal thread, and sealing element sets external screw thread, due to sealing element and heat pipe
It is welding as one, there are certain deviations for the verticality of sealing element and heat pipe, and there is also a degree of amount of deflection, heat for heat pipe itself
When pipe is installed, screw thread installation is more difficult, and the installation of especially long heat pipe is more prominent, affects the seal request of gasket.In addition,
When installation is with dismounting heat pipe, partition board hole internal thread is easy to be damaged.
Other seal forms, such as：" cartridge-type seal ", " cast bulkhead seal " etc., because its exist in various degree it is poorly sealed,
The problems such as dismounting is inconvenient, cost is high and needs particular manufacturing craft, application is not wide, not in the discussion scope of the utility model practicality.
Utility model content
The utility model provides a kind of novel heat pipe sealing structure, is let out with solving sealing structure at clapboard of heat pipe exchanger
The problem of leakage, meanwhile, achieve the effect that heat pipe installation and easy removal.
Heat pipe sealing structure described in the utility model, including partition board and sealing block, partition board are equipped with partition board hole, and heat pipe passes through
Partition board hole, partition board isolation heat pipe cold flow section and hot-fluid section, sealing block are welded on heat pipe, and penetrate partition board hole with heat pipe；
Sealing block top is equipped with the sealing plate that outer diameter is more than partition board hole aperture, and lower part sets external thread section, which is screwed on a compression
Nut；By rotatably compressing nut, the upper surface of the sealing plate of sealing block and partition board is closely pressed.
The influence for installing not heat pipe size and shape deviation of the utility model gasket, partition board hole does not set screw thread, obstructed
The mode for crossing rotating heat pipe compresses sealing ring, and sealing ring, the sealing surface of sealing ring are only compressed by way of rotatably compressing nut
With clamp nut not in the same side of partition board, sealing ring does not have relative motion, sealing ring will not in compaction process, with sealing surface
It is damaged, when heat pipe installation is with dismounting, the screw thread of sealing block and clamp nut is not damaged.
It is preferably designed for, the partition board is equipped with groove close to the lower surface position of the sealing plate of sealing block, is arranged in groove
Sealing ring；The lower surface of the sealing plate of the sealing block is closely pressed by sealing ring with partition board.
The utility model also provides a kind of heat pipe sealing structure, including partition board and sealing block, and partition board is equipped with partition board hole, heat
Across partition board hole, partition board isolation heat pipe cold flow section and hot-fluid section, sealing block are welded on heat pipe pipe, and with heat pipe penetrate every
Plate hole；Sealing block top is equipped with sealing plate, and lower part sets external thread section；A sealing ring, the outer spiral shell are set with below the sealing plate
The line section clamp nut that is screwed on closely is pressed the upper surface of the sealing plate of sealing block and partition board by rotatably compressing nut.
It is preferably designed for, the partition board is equipped with groove, the sealing ring close to the lower surface position of the sealing plate of sealing block
