Abstract

PURPOSE:To abolish the use of a clamping bolt and thin the thickness of a frame by a method wherein a belt-type thin sheet or a wire is wound more than 1 round around the outer periphery of the frame, pinching the heat transfer plate of a plate-type heat exchanger, to fix the heat exchanger. CONSTITUTION:A belt-type thin sheet 10 is wound one round around the outer periphery of a pair of frames 4, 4, pinching the assembled body of heat transfer plates 2, and the starting end of the thin sheet 10 is fixed to the final end of the same by welding 12. According to this method, a load, concentrated on respective bolts in case the heat transfer plates are clamped by the bolts, is distributed uniformly on the widthwise direction of the thin sheet 10 to obtain an equally distributed load. As a result, the frame 4 is deflected into X-direction only, therefore, thinner frame 4 can be used compared with the case of clamping effected by the bolts.

A plate heat exchanger is made up of a plurality of heat transfer plates stacked on top of each other to form a flow path for heat exchange fluid between adjacent heat transfer plates. Heat exchange takes place between the two. Conventionally, as shown in Fig. 3, a heat transfer plate (2) is sandwiched between a pair of vertical frames (4) (4), and the frames are fastened together with bolts (6) to form a flow path. It provides rigidity that can withstand the pressure of the fluid inside. Note that in the drawings, nozzles for supplying and discharging fluid are omitted for the sake of simplicity.

If B<1, then 1', the frame is required to be quite thick for its function. Therefore, the proportion of the frame in the total heat exchanger is very large both in terms of ff1ffi and therefore also in terms of cost. This is why it is desirable to make the frame thinner.

When the tightening bolt is tightened, that part becomes a single fulcrum and a concentrated load is applied to the tightening bolt, which is unfavorable in terms of strength. Stress is also concentrated around the bolt holes in the frame, so
Although it is necessary to provide reinforcement such as adding ribs (8), this becomes a cause of increased man-hours and costs.

Furthermore, in the case of tightening with bolts, the insertion position of the bolt is limited to the peripheral area excluding the heat transfer surface. In practice, this would be impossible if the bolt penetrated the heat transfer surface, as special measures would be required to prevent fluid leakage. The frame, which is fastened only at the periphery, deflects in two directions, the X direction and the Y direction, as shown in FIG. 4, when a force due to fluid pressure is applied. Therefore, the frame must be thicker than if it only flexed in one direction, as shown in FIG.

By the way, the reason why bolts are conventionally used to tighten the frame is to make it possible to disassemble the heat exchanger in consideration of convenience during maintenance, cleaning, etc. However, as technology advances, types that do not require cleaning are now available, so in the case of heat exchangers that do not require separation, there is no need to necessarily rely on bolts to tighten the frame. be.

Therefore, the main object of the present invention is to eliminate the use of tightening bolts in a plate heat exchanger and to reduce the thickness of the frame.

This invention achieves the above object by winding and fixing a strip-shaped thin plate or wire one or more times around the outer periphery of a frame that holds the heat transfer plates of a plate heat exchanger. This is what we aim to achieve.

Figure 1 shows an embodiment in which a thin plate is wound. That is, a pair of frames (4) that sandwich the assembly of heat transfer plates (2).
A strip-shaped thin plate (10) is twisted once around the outer periphery of (4). The starting and ending ends of the thin plate (lO) are indicated by the reference numeral (12

By doing so, the load that is concentrated on each bolt when tightening with bolts becomes an evenly distributed load that is evenly distributed in the width direction of the thin plate (10). As a result, the frame (4) deflects only in the X direction as shown in Figure 2, so the wall thickness of the frame (4) can be smaller than when tightening with bolts (Figure 4). .

Furthermore, if a separate F# slope is wound in the direction perpendicular to the thin plate (10) in Fig. 1, the deflection in the two directions, the X direction and the Y direction in Fig. 4, can be canceled out or at least reduced. , it becomes possible to further reduce the wall thickness of the frame.

The thin plate (10) can be made of a material and have a wall thickness that can maintain the required strength depending on the pressure of the fluid, the size of the heat exchanger, etc., and the number of turns can be set as appropriate.

First, since the frame deflects in one direction at most, the frame needs to be thinner in order to maintain the same strength. Unlike when tightening with bolts, there is no need to apply a concentrated load, which is advantageous in terms of strength, and also eliminates the need for man-hours such as adding reinforcing ribs. In this way, it is possible to provide an economical plate heat exchanger with an extremely simple overall structure. J: The above effect is particularly noticeable in large-sized, high-pressure plate heat exchangers.
