Description

Technical Field

[0001] The invention belongs to the technical field of plate heat exchange units, and in particular relates to a plate heat exchange unit with a high heat exchange rate. Background Art

[0002] The smart plate heat exchanger is a device that utilizes the convection heat exchange of a plate heat exchanger. It is usually composed of parallel stacked stainless steel or titanium plates connected to form a plate assembly of a heat exchanger. The working principle of the smart plate heat exchanger is mainly to use thin metal plates to press into heat exchange plates with a certain corrugated shape, and then stack them and fasten them with plywood and bolts. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The working fluid flows through the narrow and tortuous channel formed between the two plates. The cold and hot fluids pass through the flow channel in turn. There is an interlayer plate in the middle to separate the fluids and heat is exchanged through this plate.

[0003] After searching, the patent with announcement number CN118640715B discloses an intelligent plate heat exchanger unit. Through the setting of the first pre-installed plate and the second pre-installed plate, the existing manually staggered heat exchanger plates can be classified and pre-installed on the first pre-installed plate and the second pre-installed plate. The first pre-installed plate and the second pre-installed plate can be slid along the installation slide groove to stagger the two groups of heat exchanger plates and complete the installation of the heat exchanger plates in a unified manner.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] See also Figure 1-Figure 9 The present invention provides a technical solution: a plate heat exchanger unit with high heat exchange rate, comprising a base 1 and a baffle 2 fixedly connected to the base 1, the end of the base 1 away from the baffle 2 is fixedly connected to a hydraulic cylinder 4, the baffle 2 is fixedly connected to a side direction close to the hydraulic cylinder 4 with multiple groups of connecting rods 3, a push plate 5 adapted to the connecting rod 3 is arranged on the outer wall of one end of the hydraulic cylinder 4, a connecting block 6 is slidably connected to the outer wall of the connecting rod 3, a heat exchange plate 7 is fixedly connected to the outer wall of the connecting block 6, a heat source inlet 8 adapted to the heat exchange plate 7 is arranged on the outer wall of the baffle 2, and a heat source inlet 8 adapted to the heat exchange plate 7 is arranged on the outer wall of the baffle 2. A heat source outlet 9 adapted to the heat source inlet 8 is provided, a cold source inlet 10 adapted to the heat exchange plate 7 is provided on the outer wall of the baffle 2, a cold source outlet 11 adapted to the cold source inlet 10 is provided on the outer wall of the baffle 2, an opening and closing assembly for enabling multiple groups of heat exchange plates 7 to be opened at equal intervals is provided on the outer wall of the connecting block 6, the opening and closing assembly includes a limiting column 32 for fixing the connecting block 6 to the surface of the baffle 2 and a connecting mechanism for connecting multiple groups of connecting blocks 6 to each other, and a filtering assembly for intercepting impurities inside the cold source and the heat source is provided on the outer wall of the heat exchange plate 7.

[0026] When in use, first, multiple groups of heat exchange plates 7 are alternately sleeved on the surface of the connecting rod 3 in a positive and negative manner, and then the hydraulic cylinder 4 is started to push the push plate 5 to slide on the surface of the base 1 in the direction of the connecting rod 3, so that the push plate 5 contacts the connecting rod 3, and the push plate 5 continues to slide on the surface of the connecting rod 3, so that the push plate 5 pushes the multiple groups of heat exchange plates 7 sleeved on the surface of the connecting rod 3 to slide in the direction of the baffle 2, so that the push plate 5 and the baffle 2 squeeze the multiple groups of heat exchange plates 7, so that the front and back surfaces of the two adjacent groups of heat exchange plates 7 are closed to each other and sealed, and then the water inlet pipe and the water outlet pipe of the heat source are respectively connected to the heat source inlet 8 and the heat source outlet 9, and the water inlet pipe and the water outlet pipe of the cold source are respectively connected to the cold source inlet 10 and the cold source outlet 11, and finally the heat source to be cooled is injected into the space formed after the multiple groups of adjacent heat exchange plates 7 are closed through the heat source inlet 8. Similarly, the cold source used to cool the heat source is passed through the cold source inlet 10 is injected into the space formed after multiple groups of adjacent heat exchange plates 7 are closed, and there are multiple spaces formed after multiple groups of adjacent heat exchange plates 7 are closed, and the spatial distribution of the cold source and the heat source is that a heat source space is set between two adjacent groups of cold source spaces, so that the cold source and the heat source can be fully in contact with each other, thereby ensuring the heat exchange effect of the present invention, and then discharged through the heat source outlet 9 and the cold source outlet 11. In this process, the filtering component can intercept the impurities inside the cold source and the heat source; when cleaning the surface of the multiple groups of heat exchange plates 7, the hydraulic cylinder 4 pulls the push plate 5 to slide outward on the surface of the connecting rod 3. At this time, the outermost two groups of heat exchange plates 7 are connected to the surfaces of the baffle 2 and the push plate 5 respectively through the limit column 32, and the connecting mechanism cooperates with the mutual connection of the multiple groups of connecting blocks 6 so that when the push plate 5 slides outward on the surface of the connecting rod 3, it will pull the multiple groups of heat exchange plates 7 to open at equal intervals, which is convenient for cleaning the intercepted impurities.

[0027] See also Figure 3 and Figure 4 The filtering assembly includes a plurality of groups of V-shaped plates 12 arranged on the front outer wall of the heat exchange plate 7 and a first guide block 13 installed on the rear outer wall of the heat exchange plate 7 and adapted to the V-shaped plate 12, a first guide plate 14 adapted to the first guide block 13 is arranged on the front outer wall of the heat exchange plate 7, an arc-shaped guide block 15 adapted to the first guide plate 14 is arranged on the rear outer wall of the heat exchange plate 7, a guide block 16 adapted to the arc-shaped guide block 15 is arranged on the front outer wall of the heat exchange plate 7, a water blocking plate 17 adapted to the V-shaped plate 12 is arranged on the rear outer wall of the heat exchange plate 7, a second guide block 18 is fixedly connected to the rear outer wall of the heat exchange plate 7, and a second guide plate 19 adapted to the second guide block 18 is arranged on the front outer wall of the heat exchange plate 7.

[0028] When in use, when the front side of one heat exchange plate 7 is closed with the back side of another heat exchange plate 7, the V-shaped plate 12, the first guide block 13, the first guide plate 14, the arc-shaped guide block 15, the guide block 16, the water blocking plate 17, the second guide block 18 and the second guide plate 19 on the front and back sides of the heat exchange plate 7 will be closed to form a channel. When the cold source or the heat source enters the space formed by the closure of the two adjacent groups of heat exchange plates 7, it will flow along the surface of the V-shaped plate 12 toward the direction of the first guide block 13, and the distance between the first guide block 13 and the V-shaped plate 12 is relatively close, so that the flow speed of the cold source or the heat source will be accelerated when passing through the first guide block 13, and it will quickly pass through the surface of the first guide plate 14 into the interior of the arc-shaped guide block 15, and form a spiral through the inner wall of the arc-shaped guide block 15. The impurities are rotated at high speed inside the arc guide block 15, and the guide block 16 is used to prevent the impurities from flying out of the arc guide block 15. After the cold source or heat source is accumulated to a certain extent inside the arc guide block 15, it will overflow from the inside of the arc guide block 15 and enter the surface of the next group of V-shaped plates 12. At this time, the water blocking plate 17 will limit it, so that the cold source or heat source entering the surface of the next group of V-shaped plates 12 will precipitate, thereby separating the impurities again, and the cold source or heat source overflowing the water blocking plate 17 will pass through the second guide block 18 and the second guide plate 19 to enter the inside of the next group of arc guide blocks 15. Through the interception of impurities by multiple groups of arc guide blocks 15 and the impact force of the cold source or heat source, the impurities can be intercepted inside the heat exchange space and prevented from scaling.

[0029] See also Figure 5 The connecting mechanism includes an elastic airbag 20 arranged on the outer wall of the connecting block 6 away from the baffle 2, and the elastic airbag 20 is not arranged on the connecting block 6 close to the surface of the push plate 5, a ventilation groove 21 adapted to the elastic airbag 20 is arranged on the inner wall of the connecting block 6, an air inlet groove 22 adapted to the ventilation groove 21 is arranged on the inner wall of the heat exchange plate 7, and a sealing airbag 23 adapted to the air inlet groove 22 is arranged on the outer wall of the heat exchange plate 7.

[0030] When in use, when the push plate 5 and the baffle plate 2 squeeze multiple groups of heat exchange plates 7, the elastic airbag 20 will be squeezed first. The air inside the elastic airbag 20 will expand outward after being squeezed, thereby entering the interior of the ventilation groove 21 and passing through the ventilation groove 21 into the air inlet groove 22, so that the air enters the interior of the sealing airbag 23 and inflates the sealing airbag 23, so that the sealing airbag 23 expands and closes with the sealing airbag 23 on the surface of another group of heat exchange plates 7, thereby improving the sealing of the two adjacent groups of heat exchange plates 7 after closing.

[0031] See also Figure 6 and Figure 7The opening and closing assembly includes a connecting column 24 installed on the side of the connecting block 6 away from the elastic airbag 20, a limiting groove 25 is provided on the outer wall of the connecting column 24, a connecting sleeve 26 is fixedly connected to the inner wall of the elastic airbag 20, a clamping block 27 adapted to the limiting groove 25 is provided on the outer wall of the connecting sleeve 26, a spring sheet 28 adapted to the clamping block 27 is provided on the outer wall of the connecting sleeve 26, a connecting groove 29 adapted to the clamping block 27 is provided on the outer wall of the connecting sleeve 26, one end of the clamping block 27 is fixedly connected to a rope 30, and one end of the rope 30 extends out of the surface of the connecting block 6, and the end of the rope 30 extending out of the surface of the connecting block 6 is fixedly connected to a connecting ring 31.

[0032] When in use, the push plate 5 and the baffle plate 2 squeeze the multiple groups of heat exchange plates 7, so that one end of the elastic airbag 20 fits with the front connecting block 6, and then the push plate 5 and the baffle plate 2 continue to squeeze the multiple groups of heat exchange plates 7, so that the connecting block 6 squeezes the elastic airbag 20, and the elastic airbag 20 shrinks under the action of force. At this time, the connecting column 24 will pass through the elastic airbag 20 and enter the interior of the connecting sleeve 26, so that the connecting column 24 squeezes one end of the block 27, so that the block 27 rotates on the surface of the connecting sleeve 26 and applies a thrust to the spring sheet 28, and the connecting column 24 continues to slide into the interior of the connecting sleeve 26. When the connecting column 24 completely slides into the interior of the connecting sleeve 26, the limit groove 25 is just on the same horizontal line as the connecting groove 29. At this time, the spring sheet 28 is under the action of force The block 27 is pushed to reset so that one end of the block 27 is stuck in the inside of the limiting groove 25, thereby limiting the connecting column 24. After the hydraulic cylinder 4 pushes the push plate 5 to release the squeezing of the heat exchange plate 7, the heat exchange plate 7 close to the surface of the push plate 5 will be driven to move synchronously through the limiting column 32. At this time, the connection between the connecting sleeve 26 and the connecting column 24 will pull the elastic airbag 20 to extend outward and drive multiple groups of heat exchange plates 7 to open at equal intervals. When it is necessary to release the limit between multiple groups of heat exchange plates 7, it is only necessary to buckle the connecting ring 31 and pull the rope 30 outward, thereby pulling the block 27 to rotate, so that one end of the block 27 slides out of the inside of the limiting groove 25 to release the limit on the connecting column 24. At this time, the elastic airbag 20 shrinks under the action of the force, driving the connecting sleeve 26 to separate from the connecting column 24.

[0033] See also Figure 2 , Figure 8 and Fig. 9The opening and closing assembly also includes a limiting column 32, and the limiting column 32 is fixedly connected to the outer walls of the two groups of connecting blocks 6 in the direction close to the baffle plate 2 and the push plate 5. A fixing groove 33 adapted to the limiting column 32 is provided on one side of the baffle plate 2 and the push plate 5 close to the connecting block 6. A sliding groove 34 is provided on the outer walls of both ends of the baffle plate 2 and the push plate 5 close to the connecting block 6. A damping plate 35 is slidably connected to the inner wall of the sliding groove 34. A handle 36 is fixedly connected to the end of the damping plate 35 close to the outer side, and a slider 37 is fixedly connected to the end of the damping plate 35 away from the handle 36. A slot 38 adapted to the slider 37 is provided on the outer wall of the limiting column 32, and a groove 39 adapted to the limiting column 32 is provided on the outer wall of the slider 37.

[0034] When in use, before installing the heat exchange plate 7, push the handle 36 to drive the damping plate 35 to slide upward inside the slide groove 34, thereby driving the slider 37 to move upward synchronously, so that the groove 39 moves to the same horizontal line as the fixed groove 33, and then the multiple groups of heat exchange plates 7 are alternately sleeved on the surface of the connecting rod 3 in a positive and negative manner, so that the push plate 5 and the baffle 2 squeeze the multiple groups of heat exchange plates 7. At this time, the limiting column 32 on the outer wall of the connecting block 6 close to the surface of the push plate 5 and the baffle 2 slides into the interior of the fixed groove 33 under the action of force, and passes through the groove 39, and then the damping plate 35 is pulled downward in the slide groove 34 by the handle 36, thereby driving the slider 37 to move downward synchronously, so that the slider 37 is stuck in the interior of the card groove 38, so that the connecting block 6 and the heat exchange plate 7 can be limited by the limiting column 32.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
