この発明は、板の両側を流れる２つの流体の流量または
圧力低下を有利に調節できる要素を備えた熱交換器に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger with elements that can advantageously adjust the flow rate or pressure drop of two fluids flowing on opposite sides of the plates.
従来の公知の板型熱交換器の大部分のうちの代表的なも
のには、積重ねて組合わされた多数の板の間にできる中
間室を交互に連続するため、板を通過した分配開□部の
周囲に密封リングが取付けられている。Most of the conventionally known plate-type heat exchangers have a distribution opening □ which passes through the plates in order to alternately connect intermediate chambers formed between a large number of stacked plates. A sealing ring is installed around the perimeter.

利である。この発明の目的は、２つの流体の流れの有効
通路を違わせ、その流れを互に対向流となるようにした
熱交換器において、熱交換を最良にすることである。For example, a rectangular plate may have distribution ports leading to each chamber located at opposite corners so that fluid flows diagonally from the chambers. To increase heat exchange or to support the plates against each other due to the necessity of the plates being subjected to fluid pressure,
The surface of the plate is usually corrugated or similarly shaped. Parallel branching devices have been used to branch off portions of the fluids when the flow rates of the respective fluids are not the same, but these branching devices have the disadvantage of being in a form that reduces efficiency. An object of the present invention is to optimize heat exchange in a heat exchanger in which the effective passages of two fluid flows are different from each other so that the flows flow counter to each other.

とにある。Usually, the effective pressure of the fluid is predetermined, so by making good use of the pressure drop to some extent and appropriately determining the internal resistance in the passage, it is possible to optimize heat exchange at the effective pressure of the fluid. . According to the invention, this is achieved by suitably distributing the effective passages of the respective fluid flows and is implemented by short-circuiting the internal circuit in the form of multiple overflow closures. In fact, this principle is
This is done by directing the fluid along a helical channel from the center of the plate to the outer periphery or vice versa, preferably from the outer periphery to the center, preferably facing each other. Adjustment of the flow rate to pressure drop ratio is accomplished by increasing or decreasing the effective overall length of the flow path, and in practice by increasing or decreasing the pitch of the helical flow path. This is indeed possible by creating a true helical path circuit by causing an overflow between two adjacent circuits, shorting the circuit to some extent locally. The best effects described above can be obtained if the plate is shaped so that the number and area of the overflow closures on both sides of the plate match. A feature of the heat exchanger for the purpose of the invention is that the plates are stamped in a press to form recesses and protrusions in such a way that a recess on one side of the plate becomes a corresponding protrusion on the other side of the plate. Helical deformation part (defo
a flow path is arranged between the deformations, several sections of the deformation are interconnected, and the ends of the flow paths are connected perpendicularly to the respective planes of the plates. When a lotus is passed through the passage and the plates are stacked in contact with each other, the protrusions on the two sides face each other in pairs to form the wall of the passage,
An overflow passage is provided between the two flow passages separated by the protrusion, and the overflow passage is formed in a corresponding recess or notch provided in each protrusion of the first and second plates that touch each other. These recesses or notches are arranged so that they partially or completely coincide with each other when the plates are stacked.

る。This plate is pressed and stamped into the shape shown in the drawing, i.e. a number of concentric deformations 1 have protrusions 2 and recesses 3 on the steel plate surface; The space between the deformed part and the deformed part is flat, and a large number of flow passages arranged at the same distance D' are formed between each deformed part. These channels are connected in a helical manner via gateways 4 with a discontinuous pitch, i.e. the channel changes from an outer channel to an inner channel or vice versa, and a turning protrusion (ridge)
5 is disposed obliquely at this closed portion so as to cross the same O-shaped passage, and connects two adjacent same deformed portions 1, 1. Each plate has two holes 6, 7 in the center and two other holes 8, 9 around the periphery. The two holes 6, 8 are the beginning and end of a spiral passage on one side of the plate and the other two.
The two holes 7, 9 are the beginning and end of the passage on the other side of the plate.

もなくてもよい。The purpose of this cut-out is to provide an overflow channel 11 between adjacent channels, by means of which a large number of helical variations in the same plate are obtained. When the plates are stacked on top of each other, the notches in two adjacent plates coincide with each other, creating such an overflow passage 11. The area of the overflow passage can be adjusted by rotating one plate relative to the other. Therefore, by covering the notch in one plate with the deformed portion 1 of the other plate, overflow can be completely stopped. Figure 4a shows the tangential direction of the two overflow passages in Figure 3B-
B is a sectional view showing the total area of the two overflow passages. Fourth
Figure b is the same cross-sectional view as Figure 4a, but the plate below the one shown has been rotated circumferentially by an angle equal to the distance between the two notches 10a, 10b (Figure 4). It is shown. Two cutouts, one in each plate, are thus covered, and the other two cutouts create an overflow channel 11. 4th c
In the figure, the lower plate is rotated by an angle equal to 1/2 the distance between the notches, so that all the notches are covered. Many design variations are possible. For example, one side and the other side of the plate may be provided with the same number of notches and notches with different areas. For one fluid, an overflow channel according to FIG. 4a is chosen; for other fluids there may even be no overflow channel, as shown in FIG. 4c.

が加えられてもよい。A group of stacks in which the rotary and displaceable molds described above are used is shown in FIG. 5, in which the section B--B extends over a number of plates in the stack. . For example, in the case of a hot water heat exchanger, one or more extra connecting passages 12 (FIG. 1) may be provided, which are arranged respectively at the inlet and outlet of the main return water from the radiator heat exchanger or the like. I can imagine that. The plates have ridges (ribs) 13 in the flow channels in the usual manner, which mutually reinforce the plates, so that unequal pressures may be applied to each side of the plate.

とができる。Besides the above-mentioned combinations, there are of course other combinations as well. In this case one fluid has zero, one or two overflow channels in each B--B section and the other fluid has two, one or zero overflow channels. Instead of adding fluid to extra passages 12, such passages can be used to remove fluid. As explained above, according to the present invention, a flow path is formed between the helical deformed part in which one side of the plate is made into a recess and the other side is made into a corresponding protrusion, and the plates are stacked. When the protrusions on the two surfaces face each other to form a flow passage wall, and an overflow passage is provided between the two flow passages separated by the protrusion, the overflow passage is Since the corresponding recesses or notches provided in the respective protrusions of the first and second plates that are in contact with each other are formed so as to partially or completely coincide with each other, these overflow passages allow the same Not only can a large number of variations be obtained in the helical passages in the plates, but also the recesses or notches provided in the protrusions of two corresponding (opposed) plates can be shifted in all directions around the circumference when stacked on top of each other. Accordingly, the open area of the overflow passage can be easily adjusted and set to an appropriate size.

最良にすることができる。Therefore, not only can all the heat exchanger plates of the heat exchanger be formed by press working, making manufacturing and assembly easy, but also, in this type of heat exchanger, a predetermined effective fluid pressure is usually applied between the flow passages. By providing an overflow passage whose opening area can be arbitrarily set, the internal resistance within the passage can be set to an appropriate value, and the internal fluid can flow appropriately to optimize heat exchange.
