Description
Technical Field
The present invention relates to a welded plate heat exchanger for heat transfer between air and liquid, said heat exchanger comprising a plurality of plates, wherein each plate has an inner volume inside a peripheral flange having a flange thickness and the plates are in parallel fluid communication with an inlet and an outlet, said plates being mounted in a frame at a predetermined distance from each other such that air can flow between the plates, and wherein a plate is mounted between at least two plate holding frame members on opposite sides of said plate, wherein said plate holding frame members are provided with an outer edge and a plurality of slits in a comb-like shape extending from said outer edge.
Background
Heat exchangers of this type are known from US 2006/0201660A1 or WO2016/053100A 1.
Welded plate heat exchangers are also known, in particular from US 5,494,100, US 2012/000633a1 and US 2012/255709a 1.
Welded plate heat exchangers are widely used in the process industry for transferring heat from a medium, such as heated air, to water. The heat exchanger is made of a number of welded plates arranged in parallel in a frame between the air inlet and the oppositely located air outlet, so that air or gas can flow through the heat exchanger from the air inlet to the air outlet. The plates are mounted in the mounting frame member such that the plates are held at a mutual distance allowing air or gas to pass through the plates. Each plate is connected to an inlet manifold and an outlet manifold such that a fluid (e.g., process water) may thereby flow inside the plate, whereby heat is transferred from the air to the liquid (or vice versa).
In the process industry, such as the food and dairy industry, the textile industry, the chemical industry, etc., welded plate heat exchangers of this type have proven to be effective in providing heat transfer, thereby providing significant energy savings. Heat exchangers are typically custom-made in size and design.
A heat exchanger of the above-mentioned type is known from US 2006/0201660, wherein a plate is securely mounted between a series of plate holding frame members on opposite sides of the plate. However, due to the thermal state, the welded plates undergo thermal expansion. It is necessary to seal the liquid flow communication between the plate and the inlet and outlet to prevent leakage due to thermal expansion. To solve this problem, examples of heat exchangers are known from GB1592069 and US 2,814,469. However, another problem associated with the thermal conditions to which the panels are subjected is ensuring that the panels remain fixedly mounted in the frame. As the plates expand and contract, it has been observed that there is a risk of loss of the plates in the mounting members, which may increase the risk of leakage and increased wear and tear on the heat exchanger, thereby requiring maintenance to ensure satisfactory performance and efficiency of the heat exchanger.
In the heat exchanger disclosed in US 2006/0201660, the plates are locked between inner and outer plate sections. The air flowing through the heat exchanger and the thermal expansion and contraction cause vibrations and cause wear on the plates, which over time cause the plates to move in their fixing means.
Disclosure of Invention
It is therefore an object of the present invention to solve the problems caused by thermal expansion of welded plates in welded plate heat exchangers.
This object is achieved by a heat exchanger of the initially mentioned type, in which slits of a first type and slits of a second type are arranged in an alternating configuration, wherein the slits of the first type are formed with a narrow entry channel section having a width corresponding to the thickness of the flange and a widened opening section located behind the narrow entry channel section, and wherein the slits of the first type are adapted to receive the peripheral flange of the plate in the narrow channel section; and wherein the second type of slit is substantially straight and remains free.
According to the invention, it has been found advantageous to arrange the plates in a comb plate holding mounting member, as the plate mounting arrangement allows for thermal expansion of the plates and holds the plates in place. The plates remain in their position in the heat exchanger without having to weld the plates to the frame. By retaining the plate in the comb-like member in each slit of the first type, the slits of the second type allow some flexibility, whereby any thermal expansion in the direction of the longitudinal plate retaining member can also be absorbed.
A first type of slot adapted to receive a plate is formed with a narrow entry channel section extending from an outer edge and a widened section located behind it.
Furthermore, the narrow entry channel section of the first type of slit has a width substantially equal to the thickness of the peripheral flange of the plate. In addition, the narrow entry channel section of the first type of slit extends substantially perpendicularly from the outer edge with a length substantially corresponding to the width of the flange of the plate. This means that the plates remain fixed so that wear is reduced or even eliminated during operation of the heat exchanger. The plate flange is mainly retained in the narrow channel section, which leaves the widened section in the first type of slit substantially free, so that the plate flange only occupies the narrow channel section.
In a preferred embodiment, the slits of the second type between the slits of the first type of the receiving plate are formed with substantially equal widths.
According to the invention, the plates are preferably welded steel plates, wherein two steel plates are welded together at least along their peripheral flanges and are shaped such that there is an inner volume between said plates, and the inner volume is preferably provided with an inlet and an outlet at the opposite peripheral flanges. Moreover, the peripheral flange of each plate has a thickness substantially equal to the two steel plates of the plate and has a predetermined width of the peripheral flange of the plate.
Preferably, the first and second types of slits both have an opening at the outer edge of the frame member and extend substantially perpendicular to the outer edge and both have substantially the same length. Any thermal expansion of the plates during operation of the heat exchanger is therefore easily absorbed.
In order to ensure a secure clamping on the plate flange, it is advantageous if the narrow channel section of the first type of slit has a width substantially equal to the thickness of the peripheral flange of the plate.
Advantageously, the base of the first type of slit and the base of the second type of slit at the point furthest from the outer edge are provided with a rounded finish, such as the bottom of the semicircular shape of the slit. Thus, stress and strain concentration in the bottom of the protrusion formed by the slit is avoided.
To ease the insertion of the plate flange, at least the first type of slit is provided with a chamfered transition edge or rounded edge as a receiving portion defining an entrance into the narrow channel section.
In a preferred embodiment, the comb-shaped plate holding frame member is made of steel, preferably stainless steel, and more preferably austenitic stainless steel. This makes the heat exchanger corrosion resistant and suitable for use in food production and the like.
The comb-shaped plate holding frame member is preferably provided with a mounting portion, preferably in the form of a longitudinal inverted V-shape, in a portion opposite the outer edge. Thus, the plate holding member is easy to securely mount to the heat exchanger frame and easy to service, including replacement during service. The V-shape also provides rigidity to the long comb plate holding frame members.
In a preferred embodiment, the plate is rectangular with two side flanges and a top flange and a bottom flange, and wherein a plurality of plate holding frame members are arranged in the frame for receiving and holding the plate at each side flange and the bottom flange and top flange of the plate.
The plates, manifolds and frames, and the plate mounting members are all made of stainless steel, more preferably austenitic stainless steel. This was found to be advantageous because austenitic stainless steels cannot be hardened by heat treatment, thereby ensuring a long life of the heat exchange structure.

Detailed Description
A welded plate heat exchanger is shown in fig. 1 and 2. The heat exchanger comprises a series of plates 1 arranged in parallel in a frame 2. The frame 2 is generally cuboid with an open front rectangular side and an opposing open rear rectangular side and four rectangular sides therebetween. A heat exchanger of the type shown in fig. 1 is an air-cooled heat exchanger in which hot air passes through a frame in a flow path between a front side and a rear side and is thereby cooled as thermal energy is transferred to a liquid passing through a series of plates.
The plates 1 are mounted to the frame 2 via plate holding members 5 which traverse openings on the front and rear sides of the heat exchanger (only the front side is visible in fig. 1). Each plate 1 is provided with an internal volume inside the peripheral flange 1' (see fig. 3 and 5). Each plate 1 has an inlet (not shown) and an outlet (not shown) to provide for the flow of fluid into and out of the interior volume. The interior volumes of the plates 1 are in fluid communication with a fluid inlet manifold 3 and a fluid outlet manifold 4 such that a fluid, e.g. a cold liquid, enters via the fluid inlet manifold 3 and passes through the interior volume of each plate 1 at an elevated temperature, such as due to an air flow of hot air between the plates 1 as indicated by the arrows in fig. 1, before the fluid exits the heat exchanger via the fluid outlet manifold 4. The fluid inlet manifold 3 distributes the incoming liquid to the plates 1 arranged in parallel so that the liquid passing through the plates 1 flows simultaneously to the outlet manifold 4.
Fig. 3 is a sectional view taken along the section C-C in fig. 2. The C-C section is parallel to the plates and is located between two plates 1. As shown in fig. 3, each panel 1 is held in place along its peripheral flange 1' on at least two opposite sides of the generally rectangular panel 1 by a plurality of panel retaining members 5. The mounting of the plate 1 in the plate holding member 5 is also shown in fig. 4, which is a sectional view along the section D-D in fig. 2, and in more detail in fig. 5, which is an enlarged view of the detail E marked in fig. 4.
With particular reference to fig. 5 and 6 to 9, these are views of the individual plate holding members 5. As shown, the plate holding members 5 are elongated and they are provided with two different types of slits 6, 7, whereby it can be seen that the plate holding members 5 have a comb-like appearance. The plate 1 is arranged in a first type of slot 6 in these comb-like plate holding members 5 and the mounting arrangement allows for thermal expansion of the plate 1 and holds the plate 1 in place in the frame 2. The plates 1 are kept in their position in the heat exchanger without the need to weld the plates 1 to the frame 2. By retaining the plate 1 in the comb member 5 in each slit 6 of the first type, the slits 7 of the second type allow some flexibility, whereby any thermal expansion in the direction of the longitudinal plate retaining member 5 can also be absorbed. As shown, the two types of slits 6, 7 are arranged in an alternating configuration such that a first type of slit 6 is followed by a second type of slit 7, then a first type of slit 6, and so on.
As shown in detail in fig. 7, the slits 6, 7 in the holding member 5 alternate between a first type of slit 6 and a second type of slit 7, so that there is a second type of slit 7 between two first type of slits 6. The slits 6, 7 extend substantially perpendicular to the outer edge 9 and all slits have substantially the same length from the outer edge 9 of the holding member 5, but the slits 6, 7 are provided with different shapes. The slits 6, 7 are formed in the holding member 5, for example by cutting, so that a protrusion 10 is formed on each side of the slits 6, 7, the shape of which is substantially mirrored.
The first type of slit 6 in comb plate holding member 5 is adapted to receive the flange 1' of plate 1. The plate flange 1 'is inserted into the outermost narrow access channel section 6' of the slit 6 (see fig. 5 and 10).
The slits 7 of the second type, which are arranged between the slits 6 of the first type of the receiving plate, are formed with substantially equal widths. The first type of slit 6, which is adapted to receive the flange 1 'of the plate 1, is formed with a narrow access passage section 6' in the outer edge portion and thereafter with a widened slit section 6 ", i.e. the section of the slit furthest from the outer edge 9 (see detailed view in fig. 7).
The narrow entry channel section 6 'of the first type of slit 6 has a width substantially equal to the thickness of the peripheral flat flange 1' of the plate 1. In addition, the narrow entry section 6 'of the first type of slit 6 extends substantially perpendicularly from the outer edge with a length substantially corresponding to the width of the flange 1' of the plate 1. The narrow channel section 6 'has two parallel sides, thereby ensuring that the flat flange 1' is firmly clamped and held in place due to the width of the narrow channel section 6 'and can also slide in the channel 6' when thermally expanded. As shown in fig. 5 and in more detail in fig. 10, the flat flange 1 'of the plate 1 is inserted only into the narrow entry channel section 6' of the first type of slit 6. Thereby, the flat flange 1' does not extend into the widened slot section 6 ", or at least does not substantially extend into the widened slot section 6". Thereby, lateral thermal expansion of the plate 1 is further allowed as the widened section remains free or at least substantially free, i.e. not occupied by the plate flange 1'.
This design of the retaining member 5 with the two types of slits 6, 7 modified ensures that the plate 1 remains fixed, so that wear is reduced or even eliminated during operation of the heat exchanger, while allowing for thermal expansion of the plate during operation.
For ease of insertion and to allow for thermal expansion and contraction, the protrusion 10 defining the first type of slit 6 is provided with a chamfered or rounded edge as a receiving portion 10' defining an entrance into the narrow channel section 6' (see fig. 7) at the outer edge 9, and is further provided with an inner transition portion 10 "between the narrow channel section 6' and the widened section 6".
The second type of slit 7 is straight, preferably with a rounded finish 7 "' at the base of the second type of slit 7 at the point furthest from the outer edge 9, such as the semi-circular bottom of the slit 7. The term straight means that the second slit 7 may have two substantially parallel sides and substantially the constant width of the slit 7. However, it should be realized that other geometrical shapes of the slits 7 of the second type may be chosen. However, it is preferred that the second type of slit 7 is symmetrical in shape, so that the protrusions forming the slit 7 and the two adjacent first type of slits 6 are identical in shape to ensure the same mounting support of the adjacent plates 1.
As the widened slit section 6 "at the point furthest from the outer edge 9 is provided with a rounded finish 6" ', the base of the first type slit 6 is provided with a rounded finish 6 "', such as a semicircular bottom of the first slit 6. Therefore, internal mechanical strain is prevented from accumulating in the holding member 5 beyond an acceptable level, so that the projections 10 are prevented from breaking and the plate 1 is prevented from being lost.
The comb plate holding frame member 5 is provided with a longitudinal frame mounting portion 8 formed with a longitudinal inverted V-shape in a longitudinal portion opposite to the outer edge 9. Thus, the longitudinal plate holding members 5 have a bending stiffness, providing a secure mounting of the plate 1 in the heat exchanger.
The components of the heat exchanger are mainly made of steel, and in particular stainless steel, so that the heat exchanger can resist corrosion. Therefore, the frame and the plate are preferably made of stainless steel. The plate holding member 5 is preferably also made of steel, such as stainless steel. However, by the present invention, it should be recognized that other types of metallic materials may be used.
The invention has been described above with reference to a currently preferred embodiment. It will be appreciated, however, that variations may be provided without departing from the invention as defined in the appended claims.
