本考案は極低温機器に好適な積層板型熱交換器に関する。 The present invention relates to a laminated plate heat exchanger suitable for cryogenic equipment.
【０００２】[0002]
従来の積層板型熱交換器の１例が図２及び図３に示されている。 図２において、積層体１にはその積層方向に沿って高温流体通路２及び低温流 体通路３が形成されている。５はステンレス等からなる外殻で、この内部には積 層体１が収容され、その上端及び下端にはヘッダ4A、4Bが固定されている。６は 積層体１を組み立てる際に用いられる心棒である。 An example of a conventional laminated plate heat exchanger is shown in FIGS. 2 and 3. In FIG. 2, a high temperature fluid passage 2 and a low temperature fluid passage 3 are formed in the laminated body 1 along the laminating direction. Reference numeral 5 denotes an outer shell made of stainless steel or the like, in which the laminated body 1 is housed, and headers 4A and 4B are fixed to the upper and lower ends thereof. Reference numeral 6 is a mandrel used when the laminated body 1 is assembled.
【０００３】 図３には積層体１の詳細が示されている。 図３において、11は断熱板で、断熱性の高いFRP 等からなる。12は微少な孔を 多数個穿設してなる伝熱板で、伝熱性の良好なアルミニウム等からなる。多数の 断熱板11と伝熱板12を接着シート13を介して互いに接着しながら交互に積層する ことによって積層体１が構成される。そして、断熱材11及び接着シート13にはそ れぞれ高温流体通路２を構成する穴15及び低温流体通路３を構成する穴16が穿設 されている。FIG. 3 shows details of the laminated body 1. In FIG. 3, 11 is a heat insulating plate, which is made of FRP or the like having high heat insulating properties. Reference numeral 12 denotes a heat transfer plate formed by forming a large number of minute holes, which is made of aluminum or the like having good heat conductivity. The laminated body 1 is configured by alternately laminating a large number of heat insulating plates 11 and heat transfer plates 12 while adhering them to each other via an adhesive sheet 13. The heat insulating material 11 and the adhesive sheet 13 are respectively provided with holes 15 forming the high temperature fluid passage 2 and holes 16 forming the low temperature fluid passage 3.
【０００４】 高温流体は供給管17からヘッダ4A内に入って各高温流体通路２に分配され、こ の中を流過してヘッダ4B内で合流し、排出管18を経て流出する。低温流体は供給 管19からヘッダ4B内に入って各低温流体通路３に分配され、この中を流過してヘ ッダ4A内で合流し、排出管20を経て流出する。そして、高温流体は高温流体通路 ２内を流過する過程で低温流体通路３内を流過する低温流体と伝熱板12を介して 熱交換する。積層体１の積層方向に沿う伝熱は断熱板11によって遮断される。The high-temperature fluid enters the header 4 A from the supply pipe 17 and is distributed to the respective high-temperature fluid passages 2, passes through the high-temperature fluid passage 2 and merges in the header 4 B, and then flows out through the discharge pipe 18. The low temperature fluid enters the header 4B from the supply pipe 19 and is distributed to the low temperature fluid passages 3, flows through the low temperature fluid passages 3, merges in the header 4A, and then flows out via the discharge pipe 20. Then, the high-temperature fluid exchanges heat with the low-temperature fluid passing through the low-temperature fluid passage 3 through the heat transfer plate 12 in the process of passing through the high-temperature fluid passage 2. Heat transfer along the stacking direction of the stack 1 is blocked by the heat insulating plate 11.
【０００５】[0005]
上記従来の積層板型熱交換器においては、その作動時、外殻５の熱膨張率と積 層体１の熱膨張率とは一般に異なるため、大きな熱応力が発生する。また、熱交 換器の温端から冷端へ向かって外殻５を通って積層方向に熱が移動するため、熱 交換性能が低下する等の問題点があった。 In the above conventional laminated plate heat exchanger, a large thermal stress is generated during its operation, because the thermal expansion coefficient of the outer shell 5 and the thermal expansion coefficient of the laminated body 1 are generally different. Further, since heat moves in the stacking direction through the outer shell 5 from the hot end to the cold end of the heat exchanger, there is a problem that the heat exchange performance deteriorates.
【０００６】[0006]
本考案は上記課題を解決するために考案されたものであって、その要旨とする ところは、多数の多孔伝熱板と多数の断熱板とを交互に積層してなる積層体にそ の積層方向に沿って高温流体通路と低温流体通路とを形成するともに上記積層体 を外殻の内部に収容してなる積層板型熱交換器において、上記外殻に少なくとも １の積層方向に伸縮するベローズを設けたことを特徴とする積層板型熱交換器に ある。 The present invention was devised to solve the above-mentioned problems, and the gist thereof is to provide a laminated body in which a large number of porous heat transfer plates and a large number of heat insulating plates are alternately laminated. A laminated plate heat exchanger in which a high temperature fluid passage and a low temperature fluid passage are formed along a direction and the laminated body is housed inside an outer shell, wherein the outer shell expands and contracts in at least one laminating direction. The laminated plate heat exchanger is characterized by being provided with.
【０００７】[0007]
本考案においては、上記構成を具えているため、熱交換器の作動時、ベローズ が積層体の積層方向に沿って伸縮するので、積層体及び外殻に作用する熱応力が 小さくなる。また、外殻を通って積層方向に移動する熱が少なくなる。 In the present invention, since the bellows expands and contracts along the stacking direction of the stack when the heat exchanger operates, the thermal stress acting on the stack and the outer shell is reduced because the above-mentioned configuration is provided. Also, less heat is transferred through the outer shell in the stacking direction.
【０００８】[0008]
図１には本考案に係わる積層板型熱交換器の実施例が示されている。 １は積層体、4A、4Bはヘッダ、17は高温流体の供給管、18は高温流体の排出管 、19は低温流体の供給管、20は低温流体の排出管である。以上は図３に示す従来 のものと同様である。外殻30は積層方向に２分割され、これらは積層方向に伸縮 しうるベローズ31を介して互いに連結されている。 FIG. 1 shows an embodiment of a laminated plate heat exchanger according to the present invention. Reference numeral 1 is a laminate, 4A and 4B are headers, 17 is a high temperature fluid supply pipe, 18 is a high temperature fluid discharge pipe, 19 is a low temperature fluid supply pipe, and 20 is a low temperature fluid discharge pipe. The above is the same as the conventional one shown in FIG. The outer shell 30 is divided into two in the stacking direction, and these are connected to each other via a bellows 31 which can expand and contract in the stacking direction.
【０００９】 しかして、熱交換器の作動時、積層体１及び外殻30の熱膨張又は熱収縮量に差 が生じても、これはベローズ31の伸縮によって吸収することができ、従って、積 層体１及び外殻30に熱応力が作用するのを阻止できる。 また、熱交換器の作動時、その温端から冷端に向かって外殻30を通って熱が移 動するが、その熱移動系路中にベローズ31が介装されているため、その分だけ熱 の移動距離が長くなり、熱の移動量を低減できる。Therefore, when the heat exchanger operates, even if a difference in the amount of thermal expansion or contraction of the laminated body 1 and the outer shell 30 occurs, this can be absorbed by the expansion and contraction of the bellows 31. It is possible to prevent thermal stress from acting on the layer body 1 and the outer shell 30. Further, when the heat exchanger operates, heat is transferred from the hot end to the cold end through the outer shell 30, but since the bellows 31 is inserted in the heat transfer system passage, heat is transferred accordingly. As a result, the heat transfer distance becomes longer, and the heat transfer amount can be reduced.
【００１０】[0010]
本考案においては、熱交換器の作動時、ベローズが積層体の積層方向に沿って 伸縮するので、積層体及び外殻に作用する熱応力を低減できる。 また、外殻を通って積層方向に移動する熱を少なくしうるので、熱交換性能が 向上する。 In the present invention, since the bellows expands and contracts along the stacking direction of the stack when the heat exchanger operates, thermal stress acting on the stack and the outer shell can be reduced. In addition, since the heat that moves through the outer shell in the stacking direction can be reduced, the heat exchange performance is improved.
