高温の１次熱媒体で低温の２次熱媒体の加熱を行なうプレート式熱交換器は、 図２に示すように、複数の伝熱プレート（１）をガスケット（２）を介して積層 し、一体に締結して構成したものである。以下、このプレート式熱交換器の構造 の説明を行なう。 A plate heat exchanger that heats a low-temperature secondary heat medium with a high-temperature primary heat medium is As shown in Figure 2, multiple heat transfer plates (1) are laminated via gaskets (2). It is constructed by fastening them together. The structure of this plate heat exchanger is shown below. I will explain.
【０００３】 伝熱プレート（１）は、図４に示すように、縦長略矩形の伝熱板であり、４隅 部に熱媒体の出入口となる通路孔（３）（４）（５）（６）を有する。また、ガ スケット（２）は、伝熱プレート（１）の片面の伝熱面周辺部に装着するもので 、伝熱プレート（１）の全周、及び、片側上下の２つの通路孔（４）（６）を囲 む枠状の第１のガスケット部（2a）と、残りの２つの通路孔（３）（５）の夫々 を囲む第２のガスケット部（2b）とで構成される。0003 As shown in FIG. 4, the heat transfer plate (1) is a vertically elongated approximately rectangular heat transfer plate, with It has passage holes (3), (4), (5), and (6) that serve as inlets and outlets for the heat medium. Also, The socket (2) is attached to the periphery of the heat transfer surface on one side of the heat transfer plate (1). , surrounding the entire circumference of the heat transfer plate (1) and the two upper and lower passage holes (4) and (6) on one side. the frame-shaped first gasket part (2a) and the remaining two passage holes (3) and (5), respectively. and a second gasket part (2b) surrounding the gasket part (2b).
【０００４】 上述のようにガスケットを片面に装着した伝熱プレート（１）を、図２に示す ように複数枚積層するわけであるが、この時、伝熱プレート（１）を、平面上で １８０°回転させて伝熱プレート（１’）とし、これを伝熱プレート（１）と積 層して一体化させる。この結果、積層した伝熱プレート（１）（１’）・・・・の上 部に、通路孔（３）（６）・・・・とガスケット（２）との協働によって１次熱媒体 供給路（７）が構成され、さらに、通路孔（４）（５）・・・・とガスケット（２） との協働により２次集液通路（８）が構成される。同様に、積層した伝熱プレー ト（１）（１’）・・・・の下部には、通路孔（３）（６）・・・・とガスケット（２） の協働によって２次媒体供給路（12）が構成され、さらに、通路孔（４）（５）・・・・ とガスケット（２）の協働によって１次集液通路（11）が構成される。上記 １次熱媒体供給路（７）を流れる１次熱媒体は、通路孔（３）を通過した後に分 流して伝熱プレート（１’）のガスケット装着面上を流れ、さらに、通路孔（４ ）で集められて１次集液通路（11）へ流入する。しかし、この１次熱媒体は、ガ スケット（２）に囲まれているため、通路孔（６）を通過した後に伝熱プレート （１）のガスケット装着面上を流れることはできない。これに対し、２次熱媒体 供給路（12）を流れる２次熱媒体は、同様の構成によって、伝熱プレート（１） のガスケット装着面上を流れて２次集液通路（８）に流入するが、伝熱プレート （１’）のガスケット装着面上を流れることはできない。従って、このような構 成により、伝熱プレート（１）（１’）の間に１次熱媒体流路（９）と２次熱媒 体流路（10）が交互に構成されることになる。そして、１次熱媒体流路（９）を 流れる１次熱媒体と２次熱媒体流路（10）を流れる２次熱媒体とが伝熱プレート （１）、或いは、（１’）を介して熱交換を行なう。0004 Figure 2 shows a heat transfer plate (1) with a gasket attached to one side as described above. At this time, the heat transfer plate (1) is placed on a flat surface. Rotate 180° to form a heat transfer plate (1'), and stack this with heat transfer plate (1). Layer and integrate. As a result, the top of the laminated heat transfer plates (1) (1')... In the part, the primary heat medium is A supply path (7) is configured, and further includes passage holes (4), (5)... and a gasket (2). A secondary liquid collection passageway (8) is constructed in cooperation with the secondary liquid collecting passageway (8). Similarly, laminated heat transfer plates At the bottom of the holes (1) (1')..., there are passage holes (3) (6)... and gaskets (2). A secondary medium supply path (12) is constructed by the cooperation of the passage holes (4), (5), etc. A primary liquid collection passageway (11) is configured by the cooperation of the gasket (2) and the gasket (2). the above The primary heat medium flowing through the primary heat medium supply path (7) is separated after passing through the passage hole (3). It flows over the gasket mounting surface of the heat transfer plate (1'), and further flows through the passage hole (4'). ) and flows into the primary liquid collection passageway (11). However, this primary heat medium is Because it is surrounded by the sket (2), the heat transfer plate passes through the passage hole (6). (1) It cannot flow on the gasket mounting surface. On the other hand, the secondary heat medium The secondary heat medium flowing through the supply path (12) is connected to the heat transfer plate (1) by a similar configuration. The liquid flows on the gasket mounting surface of the gasket and flows into the secondary liquid collection passage (8), but It cannot flow on the gasket mounting surface (1'). Therefore, such a structure By forming The body flow paths (10) are arranged alternately. And the primary heat medium flow path (9) The primary heat medium that flows and the secondary heat medium that flows through the secondary heat medium flow path (10) are connected to the heat transfer plate. Heat exchange is performed via (1) or (1').
【０００５】 実際には、上記構成の伝熱プレート（１）（１’）を多数積層し、例えば、１ 次熱媒体として温水を使用し、２次熱媒体として食品流体を使用して食品流体の 加熱殺菌を行なっている。[0005] In reality, a large number of heat transfer plates (1) (1') having the above configuration are stacked, for example, one Using hot water as the secondary heating medium and food fluid as the secondary heating medium. Heat sterilization is performed.
【０００６】[0006]
ここで、上記構成のプレート式熱交換器を模式的に表せば、図５に示す構成と なる。図５において、実線部分は１次熱媒体、例えば、温水の流路を示し、破線 部分は２次熱媒体、例えば、食品流体の流路を示す。また、10a・・・・10dは２次熱 媒体流路（10）を示し、ａ1・・・・ａ4は、２次熱媒体流路（10）に２次熱媒体を供 給する通路孔（６）を示す。同様に、9a・・・・9dは、１次熱媒体流路（９）を示し 、ｂ1・・・・ｂ4は１次熱媒体流路（９）に１次熱媒体を供給する通路孔（３）（３ ）を示す。また、Ｔ1・・・・Ｔ4は、熱交換終了後の２次熱媒体の温度を示す。Here, if the plate heat exchanger having the above configuration is schematically represented, it will have the configuration shown in FIG. In FIG. 5, solid line portions indicate flow paths for a primary heat medium, such as hot water, and dashed line portions indicate flow paths for a secondary heat medium, such as food fluid. Further, 10a...10d indicate secondary heat medium flow paths (10), and a1 ... a4 indicate passage holes for supplying the secondary heat medium to the secondary heat medium flow paths (10). (6) is shown. Similarly, 9a...9d indicate the primary heat medium flow path (9), and b1 ... b4 are channels for supplying the primary heat medium to the primary heat medium flow path (9). Hole (3) (3) is shown. Further, T 1 ...T 4 indicate the temperature of the secondary heat medium after the heat exchange is completed.
【０００７】 従来の装置では、通路孔ｂ1・・・・ｂ4の開口径は同じであるため、9a・・・・9dを流 れる１次熱媒体の流量は同じである。又、同様に、ａ1・・・・ａ4の開口径も同じで あるため、10a・・・・10dを流れる２次熱媒体の流量も同じである。そして、9aを流 れる１次熱媒体は、両側の10c・10dを流れる２次熱媒体を加熱し、同様に、9bを 流れる１次熱媒体が10b・10cを流れる２次熱媒体を、9cを流れる１次熱媒体が10 a・10bを流れる２次熱媒体を加熱する。ところが、9dを流れる１次熱媒体は、一 側の10aを流れる２次熱媒体のみを加熱するため、10aを流れる２次熱媒体は、他 の２次熱媒体より多量の熱を与えられて温度Ｔ1が高くなってしまう（∴Ｔ1＞Ｔ 2 ＝Ｔ3）。また、10b・10cを流れる２次熱媒体は、夫々の両側に配置された9a・・・・ 9cを流れる１次熱媒体に両側から加熱されるのに対し、10dを流れる２次熱媒 体は、一側の9aを流れる１次熱媒体によってのみ加熱されるため、他の２次熱媒 体に比べて温度Ｔ4が低くなってしまう（∴Ｔ1＞Ｔ2＝Ｔ3＞Ｔ4）。[0007] In the conventional device, the passage hole b1...bFourSince the opening diameters are the same, flow 9a...9d. The flow rate of the primary heat transfer medium is the same. Also, similarly, a1...aFourThe aperture diameter is also the same. Therefore, the flow rate of the secondary heat medium flowing through 10a...10d is also the same. Then run 9a The primary heat transfer medium flowing through 10c and 10d on both sides heats the secondary heat transfer medium flowing through 9b. The primary heat medium flowing through 10b and 10c is the secondary heat medium flowing through 9c, and the primary heat medium flowing through 9c is 10 Heats the secondary heat medium flowing through a and 10b. However, the primary heat medium flowing through 9d is Since only the secondary heat medium flowing through side 10a is heated, the secondary heat medium flowing through 10a is A large amount of heat is given by the secondary heat medium, and the temperature T1becomes high (∴T1＞T 2 =T3). In addition, the secondary heat medium flowing through 10b and 10c is placed on each side of 9a... The primary heat medium flowing through 9c is heated from both sides, while the secondary heat medium flowing through 10d The body is heated only by the primary heat medium flowing through one side 9a, so the other secondary heat medium The temperature T4 becomes lower than that of the body (∴T1＞T2=T3＞TFour).
【０００８】 このように、従来のプレート式熱交換器では、複数の２次熱媒体流路10a・・・・1 0dのうちの両側端部にある２次熱媒体流路10a、10dを流れる２次熱媒体の受熱量 が他と異なるため、２次熱媒体の温度が各流路で不均一になる問題があった。[0008] In this way, in the conventional plate heat exchanger, a plurality of secondary heat medium flow paths 10a...1 Amount of heat received by the secondary heat medium flowing through the secondary heat medium flow paths 10a and 10d at both ends of 0d Since the temperature of the secondary heat medium is different from that of the others, there is a problem that the temperature of the secondary heat medium becomes non-uniform in each flow path.
【０００９】 そこで本考案は、伝熱プレート間に形成された複数の２次熱媒体流路を流れる ２次熱媒体の加熱、又は、冷却を均一に行い、２次熱媒体の温度を全ての流路で 一定にすることのできるプレート式熱交換器を提供することを目的とする。[0009] Therefore, in the present invention, the heat transfer medium flows through a plurality of secondary heat transfer channels formed between heat transfer plates. The secondary heating medium is heated or cooled uniformly, and the temperature of the secondary heating medium is maintained in all channels. The purpose is to provide a plate type heat exchanger that can be kept constant.

上記目的を達成するため、本考案は、少なくとも２つの通路孔が形成された複 数の伝熱プレートをガスケットを介して積層し、上記２つの通路孔とガスケット との協働で１次熱媒体供給路と２次熱媒体供給路とを構成すると共に、隣接する 伝熱プレートとの協働で伝熱プレートの両面に１次熱媒体流路と２次熱媒体流路 とを別途構成したものであって、上記１次熱媒体供給路から伝熱プレートに形成 した一方の通路孔を介して１次熱媒体流路に供給された１次熱媒体と上記２次熱 媒体供給路から他方の通路孔を介して２次熱媒体流路に供給された２次熱媒体と が伝熱プレートを介して熱交換を行なうプレート式熱交換器において、側端部に 位置する１次熱媒体流路、或いは、２次熱媒体流路に１次、或いは、２次熱媒体 を供給する通路孔の開口径を他の通路孔の開口径よりも小さくする。 In order to achieve the above object, the present invention provides a composite structure having at least two passage holes. A number of heat transfer plates are stacked together via a gasket, and the above two passage holes and the gasket are stacked together. The primary heat medium supply path and the secondary heat medium supply path are configured in cooperation with the adjacent In cooperation with the heat transfer plate, a primary heat medium flow path and a secondary heat medium flow path are formed on both sides of the heat transfer plate. and is separately configured, and is formed on the heat transfer plate from the primary heat medium supply path. The primary heat medium and the secondary heat supplied to the primary heat medium flow path through one of the passage holes A secondary heat medium is supplied from the medium supply path to the secondary heat medium flow path through the other passage hole. In a plate heat exchanger that exchanges heat through heat transfer plates, there is a The primary or secondary heat medium is located in the primary heat medium flow path or the secondary heat medium flow path. The opening diameter of the passage hole that supplies this is made smaller than the opening diameter of the other passage holes.
【００１１】[0011]
側端部に位置する１次、或いは２次熱媒体流路に熱媒体を供給する通路孔の開 口径を他の通路孔よりも小径とすることにより、上記２つの熱媒体流路を流れる 熱媒体の流量が減少する。例えば、図５の右側に示すように、側端部に１次熱媒 体流路（9d）が位置している場合、通路孔ｂ4の開口径を小さくすることにより 、9dを流れる１次熱媒体の流量が減少する。すると、その側方の10aを流れる２ 次熱媒体の受熱量も減り、10aを流れる２次熱媒体の温度Ｔ1が低下する。従って 、ｂ4の開口径を適宜調整することによってＴ1＝Ｔ2＝Ｔ3が達成される。By making the opening diameter of the passage hole that supplies the heat medium to the primary or secondary heat medium flow path located at the side end smaller than the other passage holes, the heat flowing through the two heat medium flow paths is reduced. The flow rate of the medium is reduced. For example, as shown on the right side of Figure 5, when the primary heat medium flow path (9d) is located at the side end, by reducing the opening diameter of passage hole b4 , the primary heat flowing through 9d can be reduced. The flow rate of the medium is reduced. Then, the amount of heat received by the secondary heat medium flowing through 10a on the side also decreases, and the temperature T 1 of the secondary heat medium flowing through 10a decreases. Therefore, T 1 =T 2 =T 3 can be achieved by appropriately adjusting the aperture diameter of b 4 .
【００１２】 また、図５の左側に示すように、側端部に２次熱媒体流路10dが位置している 場合、通路孔ａ4の開口径を小さくすることにより、10dを流れる２次熱媒体の流 量が減少する。すると、9aを流れる１次熱媒体からの受熱量が10dを流れる２次 熱媒体の単位量あたりでは増大し、この結果、10dを流れる２次熱媒体の温度Ｔ4 が上昇する。従って、ａ4の開口径を適宜変更することによってＴ1＝Ｔ2＝Ｔ3＝ Ｔ4が達成できる。[0012] Furthermore, as shown on the left side of Fig. 5, when the secondary heat medium flow path 10d is located at the side end, by reducing the opening diameter of the passage hole a4 , the secondary heat medium flow path 10d can be The flow rate of the heating medium decreases. Then, the amount of heat received from the primary heat medium flowing through 9a increases per unit amount of the secondary heat medium flowing through 10d, and as a result, the temperature T 4 of the secondary heat medium flowing through 10d increases. Therefore, T 1 =T 2 =T 3 =T 4 can be achieved by appropriately changing the aperture diameter of a 4 .
【００１３】 このように、側端部にある熱媒体流路が１次用、或いは、２次用であるを問わ ず、夫々の熱媒体流路に熱媒体を供給する通路孔の開口径を小さくすることによ り、複数ある２次熱媒体流路を流れる２次熱媒体の温度を均一に保つことができ る。[0013] In this way, it does not matter whether the heat medium flow path at the side end is for primary or secondary use. First, by reducing the opening diameter of the passage hole that supplies the heat medium to each heat medium flow path. This makes it possible to maintain a uniform temperature of the secondary heat medium flowing through the multiple secondary heat medium flow paths. Ru.

【００２０】 上述のように、9d’を流れる１次熱媒体の流量が減少するので、その側方の10 a’を流れる２次熱媒体の受熱量が減少し、10a'を流れた２次熱媒体の温度Ｔ'1 が低下する。従って、ｂ'4の開口径を適宜調整することによってＴ'1＝Ｔ'2＝Ｔ '3が達成できる。As mentioned above, since the flow rate of the primary heat medium flowing through 9d' decreases, the amount of heat received by the secondary heat medium flowing through 10a' on the side thereof decreases, and the secondary heat medium flowing through 10a' decreases. The temperature T'1 of the heat medium decreases. Therefore, by appropriately adjusting the aperture diameter of b' 4 , T' 1 =T' 2 =T' 3 can be achieved.
【００２１】 また、10d'を流れる２次熱媒体の流量が減少するのでこの２次熱媒体の単位量 あたりの受熱量が増大することになり、この結果、10d'を流れた２次熱媒体の温 度Ｔ'4が上昇する。従って、ａ'4の開口径を適宜変更することによってＴ'1＝Ｔ '2＝Ｔ'3＝Ｔ'4が達成できる。[0021] Furthermore, since the flow rate of the secondary heat medium flowing through 10d' decreases, the amount of heat received per unit amount of this secondary heat medium increases, and as a result, the amount of heat received per unit amount of this secondary heat medium increases. The temperature T'4 increases. Therefore, by appropriately changing the aperture diameter of a'4, T' 1 =T' 2 =T' 3 =T' 4 can be achieved.

As a result, both sides of the plurality of secondary heat medium flow paths (10) The temperature of the secondary heat medium flowing through the secondary heat medium flow path located at the end is calculated by comparing the temperature of the secondary heat medium flowing through the other flow path. It becomes possible to make it the same as the secondary heat medium. Plate heat exchanger with this configuration For example, hot water can be used as the primary heat medium, and hot water can be used as the secondary heat medium. Even when using a food fluid as a fluid, the food fluid can be heated uniformly in each flow path become able to.
【００２３】 尚、本実施例では、１次熱媒体で２次熱媒体を加熱する場合のみを説明したが 、１次熱媒体で２次熱媒体を冷却する場合にも上述の構成が適用できる。[0023] In addition, in this example, only the case where the secondary heating medium is heated by the primary heating medium was explained. , the above-described configuration can also be applied to the case where the secondary heat medium is cooled by the primary heat medium.
