Description

Technical Field

[0001] This utility model relates to the field of plate heat exchangers, and in particular to a novel plate heat exchanger sealing gasket. Background Technology

[0002] An existing patent (publication number: CN104792216A) discloses a sealing gasket used in a plate heat exchanger. This gasket includes at least one diverting gasket that divides the flow path of the heat exchange fluid across the heat exchange plates into at least two branched channels. The diverting gasket has openings, creating a series connection between the branched channels on the heat exchange plates, thus forming an S-shaped flow path for the heat exchange fluid. However, this gasket lacks an external structure for positioning during use, making it difficult to conveniently install the gasket on the side of the plate. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a novel plate heat exchanger sealing gasket that ensures the lateral and vertical positions of the gasket body on the plate.

[0004] The objective of this utility model is achieved through the following technical solution: A novel plate heat exchanger gasket includes a gasket body, a first sealing ring, an arc-shaped connecting strip, a rectangular outer block, a limiting insert, a support strip plate, an upper support strip plate, a side connecting strip, an upper positioning slide rail, and a positioning frame. The gasket body has a first sealing ring distributed at both the upper and lower ends of the gasket body. The gasket body also has an arc-shaped outer ring distributed at both the upper and lower ends of the gasket body. The first sealing ring and the arc-shaped outer ring are symmetrically distributed. The gasket body is connected to the arc-shaped connecting strip, which is connected to a reinforcing connecting strip. The reinforcing connecting strip is connected to the first sealing ring. A set of reinforcing connecting strips is distributed outside the first sealing ring. The gasket body fits against the heat exchanger plates between adjacent plates. The first sealing ring and the arc-shaped outer ring correspond to four holes on the plates, respectively.

[0005] The gasket body has a main body side strip on its side. Two sets of main body side strips are symmetrically arranged at both ends of the gasket body. The main body side strip has a rectangular outer block on its side. The rectangular outer block is attached to the plate. One end of the rectangular outer block has a limiting slot, and the other end of the rectangular outer block has a limiting insert. Adjacent rectangular outer blocks are attached to each other.

[0006] The limiting block is adapted to the limiting slot. The limiting block is inserted into the limiting slot. The upper surface of the support strip plate is in contact with the lower surface of the rectangular outer block. The side of the support strip plate is in contact with the plate. The lower part of the side connecting strip is connected to the support strip plate. The upper part of the side connecting strip is connected to the upper support strip plate. The lower surface of the upper support strip plate is in contact with the upper surface of the plate.

[0007] Multiple side connecting strips are evenly distributed between the support strip plate and the upper support strip plate. A set of upper support strip plates are distributed on the upper part of the plate. The upper part of the upper support strip plate has an upper positioning slide rail with an inner T-shaped slide groove. The lower ends of the positioning frame have frame lower inserts. The frame lower inserts are adapted to the inner T-shaped slide grooves. The frame lower inserts are inserted into the inner T-shaped slide grooves and slide within the inner T-shaped slide grooves. Beneficial effects

[0008] 1. The gasket body of this utility model is attached between two plates, forming two independent flow channel systems in the heat exchanger: a hot-side flow channel and a cold-side flow channel. This allows the two fluids to flow in opposite or staggered directions on both sides of the plates, fundamentally preventing the mixing of hot and cold fluids. It ensures that the two fluids exchange heat only through the plates and do not come into direct contact. The rectangular outer block is attached to the side of the plate. The symmetrical attachment of the rectangular outer block to the sides of the plate ensures the lateral position of the gasket body on the plate, preventing lateral misalignment of the flow channel with the first sealing ring and the arc-shaped outer ring. This locks the lateral position of the gasket body, ensuring that the lateral boundaries of the flow channel with the first sealing ring and the arc-shaped outer ring are completely aligned, preventing sealing leaks caused by lateral offset and reducing the risk of fluid leakage.

[0009] 2. In this utility model, the supporting strip plate and the upper supporting strip plate are connected by multiple side connecting strips. The upper supporting strip plate is placed on the upper part of the plate and its height is controlled by the upper supporting strip plate. The upper surface of the supporting strip plate is in contact with the rectangular outer block. By supporting the rectangular outer block, the vertical position of the gasket body is controlled, preventing the gasket body from being vertically misaligned on the side of the plate. This ensures that the No. 1 sealing ring, the arc-shaped outer ring and the flow channel are vertically aligned, and the vertical height of the gasket body is precisely controlled, so that the sealing assembly and the flow channel always remain vertically aligned, avoiding non-fitting of the sealing surface due to vertical misalignment, and further enhancing the sealing effect. The limiting block is inserted into the limiting slot to ensure that the sides of two adjacent gasket bodies are aligned, forcing the sides of adjacent gasket bodies to be flush, avoiding discontinuous flow channel splicing due to adjacent misalignment, and reducing local eddies or blockages of fluid in the flow channel. The lower insert of the frame is inserted into the inner T-shaped slide groove, and a set of symmetrical upper supporting strip plates are connected in series by the positioning frame to prevent the gasket body from falling off the upper part of the plate.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A novel plate heat exchanger gasket includes a gasket body 01, a first sealing ring 02, an arc-shaped connecting strip 03, a rectangular outer block 05, a limiting insert 07, a support strip plate 10, an upper support strip plate 11, a side connecting strip 12, an upper positioning slide rail 13, and a positioning frame 15. The gasket body 01 has a first sealing ring 02 distributed at both its upper and lower ends. The gasket body 01 also has an arc-shaped outer ring 08 distributed at both its upper and lower ends. The first sealing ring 02 and the arc-shaped outer ring 08 are symmetrically distributed. The gasket body 01 is attached between two plates to form two heat exchangers. The independent flow channel system consists of a hot-side flow channel and a cold-side flow channel, allowing the two fluids to flow in opposite or staggered directions on both sides of the plate. This fundamentally avoids the mixing of hot and cold fluids and ensures that the two fluids exchange heat only through the plate without direct contact. The gasket body 01 is connected to the arc-shaped connecting strip 03, which is connected to the reinforcing connecting strip 04. The reinforcing connecting strip 04 is connected to the first sealing ring 02. A set of reinforcing connecting strips 04 is distributed outside the first sealing ring 02. The gasket body 01 is in contact with the heat exchanger plate and is located between adjacent plates. The first sealing ring 02 and the arc-shaped outer ring 08 correspond to the four holes on the plate, respectively.

[0015] Example 2: The gasket body 01 of this utility model has a main body side strip 09 on its side. Two sets of main body side strips 09 are symmetrically arranged at both ends of the gasket body 01. The main body side strip 09 has a rectangular outer block 05 on its side. The rectangular outer block 05 is attached to the plate. By attaching the symmetrical rectangular outer block 05 to both sides of the plate, the lateral position of the gasket body 01 on the plate is ensured, preventing the flow channel from being misaligned with the first sealing ring 02 and the arc-shaped outer ring 08. The lateral position of the gasket body 01 is locked, ensuring that the flow channel is completely aligned with the lateral boundaries of the first sealing ring 02 and the arc-shaped outer ring 08, preventing sealing leaks caused by lateral offset, and reducing the risk of fluid leakage. One end of the rectangular outer block 05 has a limiting slot 06, and the other end of the rectangular outer block 05 has a limiting insert 07. Adjacent rectangular outer blocks 05 are attached to each other.

[0016] Example 3: The limiting insert 07 of this utility model is adapted to the limiting slot 06. The limiting insert 07 is inserted into the limiting slot 06 to ensure the side alignment of two adjacent gasket bodies 01, forcing the sides of adjacent gasket bodies 01 to be flush, avoiding discontinuous flow channel splicing caused by adjacent misalignment, and reducing local eddies or blockages of fluid in the flow channel. The upper surface of the support strip plate 10 is in contact with the lower surface of the rectangular outer block 05, and the side of the support strip plate 10 is in contact with the plate. The lower part of the side connecting strip 12 is connected to the support strip plate 10, and the upper part of the side connecting strip 12 is connected to the support strip plate 10. The upper support plate 11 is connected, and its lower surface is in contact with the upper surface of the plate. The upper support plate 11 is placed on the upper part of the plate. The height of the support strip plate 10 is controlled by the upper support plate 11. The upper surface of the support strip plate 10 is in contact with the rectangular outer block 05. The support strip plate 10 supports the rectangular outer block 05, thereby controlling the vertical position of the gasket body 01 and preventing the gasket body 01 from being vertically misaligned on the side of the plate. This ensures that the first sealing ring 02, the arc-shaped outer ring 08 and the flow channel are vertically aligned. The vertical height of the gasket body 01 is precisely controlled so that the sealing assembly and the flow channel are always vertically aligned, avoiding non-fitting of the sealing surface due to vertical misalignment, and further enhancing the sealing effect.

[0017] Example 4: In this utility model, multiple side connecting strips 12 are evenly distributed between the support strip plate 10 and the upper support strip plate 11. A set of upper support strip plates 11 are distributed on the upper part of the plate. The upper part of the upper support strip plate 11 has an upper positioning slide rail 13. The upper positioning slide rail 13 has an inner T-shaped slide groove 14. The lower ends of the positioning frame 15 have frame lower inserts 16. The frame lower inserts 16 are adapted to the inner T-shaped slide groove 14. The frame lower inserts 16 are inserted into the inner T-shaped slide groove 14 and slide in the inner T-shaped slide groove 14. The positioning frame 15 connects a symmetrical set of upper support strip plates 11 in series to prevent the gasket body 01 from falling off the upper part of the plate.

[0018] Example 5: The installation steps of this utility model are as follows: First, attach the gasket body 01 to the heat exchanger plate, insert the limiting block 07 into the limiting slot 06, connect the upper support strip 11 and the support strip plate 10 to the upper and lower ends of the upper support strip 11 respectively, attach the upper surface of the support strip plate 10 to the lower surface of the rectangular outer block 05, attach the lower surface of the upper support strip 11 to the plate, attach the side of the support strip plate 10 to the side of the plate, and insert the lower insert block 16 of the frame into the inner T-shaped slide groove 14.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
