Description

Technical Field

[0001] This invention relates to the field of heat exchange technology, specifically a heat exchange device for a high-temperature mold temperature controller. Background Technology

[0002] A high-temperature mold temperature controller is a device that precisely controls the temperature of molds and is widely used in industrial production. In simple terms, the working principle of a high-temperature mold temperature controller is an internal circulation heating process. The mold temperature controller and the equipment being heated form a closed pipeline. An electric heater generates heat, a circulating pump conducts heat through the medium, and an intelligent control system controls the temperature of the fluid within the circulation system, providing high and low temperature circulating media to the equipment requiring cooling or heating. High-temperature mold temperature controllers are divided into two main categories: high-temperature water temperature controllers and high-temperature oil temperature controllers. The difference between the two lies in the heat transfer medium used.

[0003] Heat exchange devices play a role in cooling in high-temperature mold temperature controllers. Common examples include shell-and-tube heat exchangers. During heat exchange, coolant flows from the tube side of the heat exchange device and exchanges heat with the heat transfer medium flowing in the shell side. The liquid heat transfer medium conducts heat to the coolant in the tube side during contact with the outer wall of the tube side. The contact area between the heat transfer medium and the outer wall of the tube side directly affects the heat exchange efficiency and effect of the heat exchange device. However, the flow rate of the heat transfer medium entering the heat exchange device is not constant. It varies according to the mold production stage. When there is less heat transfer medium entering the shell side in a fixed space, the heat transfer medium will accumulate in the lower part of the shell side under the action of gravity, resulting in less contact between the heat transfer medium and the tube side and a limited contact area, thus affecting the heat exchange effect. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a heat exchange device for a high-temperature mold temperature controller. This invention uses an adjustable disc that is movably and sealed between two end discs, thereby ensuring that the amount of heat transfer medium entering the inner side of the housing is always adapted to the space, thus guaranteeing the contact quantity between the heat transfer medium and the heat transfer pipe, and improving the heat exchange effect of the heat exchange device.

The two end plates are connected by a heat-conducting pipe on opposite sides. An adjusting plate is movably and sealed between the two end plates on the inner side of the shell. The adjusting plate is slidably and sealed to multiple heat-conducting pipes. A liquid outlet groove is provided along the axial direction at the lower position of the inner wall of the shell. A U-shaped liquid outlet pipe is slidably and sealed to the liquid outlet groove. The U-shaped liquid outlet pipe is connected to the outer edge of the adjusting plate. One end of the U-shaped liquid outlet pipe is connected to the left end of the central cavity, and the other end is connected to another second pipe joint through a flexible hose. A connecting hole is provided through the right end plate in the axial direction.

[0006] Preferably, the end plate is rotatably and sealingly connected to the inner wall of the shell; the inner wall of the shell is provided with a corrugated groove along the axial direction; a corrugated block is movably and sealingly connected in the corrugated groove; the corrugated block is fixedly connected to the outer edge of the adjusting plate; and the inner side of the U-shaped liquid outlet pipe is rotatably and sealingly connected to the outer edge of the adjusting plate.

[0007] Preferably, the corrugated groove has a span angle greater than 180 degrees in the circumferential direction on the inner wall of the shell; the corrugated groove is staggered from the liquid outlet groove.

[0008] Preferably, baffles are evenly distributed between the adjusting plate and the left-side end plate; the baffles are eccentrically notched; the baffles are in movable sealing contact with the inner wall of the shell; the notches on adjacent baffles are staggered and far apart from each other; the left-side end plate and the baffles, adjacent baffles, and the baffles and adjusting plate are all connected by a first spring; the heat pipe passes through the baffles and is slidably and sealingly connected to the baffles.

[0009] Preferably, the adjustment disc is connected to the right end disc by a second spring; the sum of the spring forces of the first spring on the left side of the adjustment disc is balanced with the spring force of the second spring on the right side.

[0010] Preferably, multiple upper sealing blocks are movably and sealingly connected within the corrugated groove; a lower sealing block is slidably and sealingly connected within the liquid outlet groove; the upper sealing blocks are inverted U-shaped, and the lower sealing blocks are upright U-shaped; the number of upper and lower sealing blocks is the same as the number of baffles; the inner sides of the upper and lower sealing blocks are movably and sealingly connected to the outer edge of the baffles.

[0011] Preferably, the hose is made of an elastic material; a retainer is fitted on the outer wall of the hose; the retainer is slidably connected in the liquid outlet groove.

[0012] Preferably, the adjusting plate is movably and sealed to the heat-conducting pipe through a control hole; the adjusting plate is composed of multiple adjusting sleeves on the outer side and adjusting blocks on the inner side; adjacent adjusting sleeves are slidably and sealed to each other; the innermost adjusting sleeve and adjusting block are slidably and sealed to each other; the outermost adjusting sleeve is fixedly connected to the corrugated block; the outermost adjusting sleeve is movably and sealed to the U-shaped liquid outlet pipe; the control hole is provided on the adjusting sleeves and adjusting blocks; the first spring and the second spring are connected to the outermost adjusting sleeve.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The present invention uses an adjustable disc to be movably sealed between two end discs, thereby ensuring that the amount of heat transfer medium entering the inner side of the housing is always adapted to the space, thus guaranteeing the contact quantity and contact area between the heat transfer medium and the heat transfer pipe, thereby improving the heat exchange effect of the heat exchange device.

[0016] 2. In this invention, as the adjusting disc moves along the inner side of the shell, it drives the corrugated block to move along the corrugated groove. This causes the adjusting disc to rotate back and forth while moving axially along the shell. During the rotation of the adjusting disc, multiple heat-conducting pipes rotate inside the shell. As the adjusting disc rotates, the heat-conducting pipes can agitate the heat-conducting medium in the left cavity, so that more heat-conducting medium comes into contact with the heat-conducting pipes. After the heat-conducting medium is agitated, the contact area with the heat-conducting pipes is increased, thereby improving the heat exchange efficiency between the heat-conducting medium and the coolant in the heat-conducting pipes.

[0017] 3. Because the notches on the adjacent baffles are staggered and far apart, the flow direction of the heat transfer medium in the left cavity is from left to right and in a corrugated shape, thereby extending the flow path of the heat transfer medium in the left cavity and further improving the heat exchange effect between the heat transfer medium and the heat transfer pipe. In addition, since the baffles can move with the movement of the regulating plate, the flow path of the heat transfer medium in the left cavity is extended on the one hand, and interference between the baffles and the regulating plate is avoided on the other hand.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 8 As shown, the present invention includes the following embodiments:

[0030] Example 1: A heat exchange device for a high-temperature mold temperature controller includes a tubular shell 1 and an end cap 2 with a first pipe joint 21 fixedly connected to the end of the shell 1; two end plates 3 are connected to the inner side of the shell 1; the two end plates 3 divide the inner side of the shell 1 into a central cavity 31 and two end cavities 32; a second pipe joint 11 communicating with the central cavity 31 is fixedly connected to the outer wall of the shell 1; the two second pipe joints 11 are arranged axially away from each other in the shell 1; one second pipe joint 11 is arranged higher and the other second pipe joint 11 is arranged lower; the two end plates 3 are arranged axially away from each other. One side is connected by a heat-conducting pipe 4; an adjusting plate 5 is movably and sealed between the two end plates 3 on the inner side of the shell 1; the adjusting plate 5 is slidably and sealed to multiple heat-conducting pipes 4; a liquid outlet groove 12 is provided along the axial direction at the lower position of the inner wall of the shell 1; a U-shaped liquid outlet pipe 13 is slidably and sealed to the liquid outlet groove 12; the U-shaped liquid outlet pipe 13 is connected to the outer edge of the adjusting plate 5; one end of the U-shaped liquid outlet pipe 13 is connected to the left end of the central cavity 31, and the other end is connected to another second pipe joint 11 through a hose 14; the right end plate 3 is provided with a connecting hole 33 through the axial direction.

[0031] After connecting the two first pipe joints 21 and the two second pipe joints 11 of the heat exchange device to the corresponding pipes of the high-temperature mold temperature controller, coolant with a certain pressure enters the right-hand end cavity 32 from right to left along the right-hand first pipe joint 21. For ease of description, the adjusting plate 5 divides the space in the middle cavity 31 into a left cavity 311 on the left and a right cavity 312 on the right. The right end cavity 32 is connected to the right cavity 312 through a connecting hole 33. In this way, the coolant in the right end cavity 32 will enter the right cavity 312 along the connecting hole 33, so that the right cavity 312 is filled and... The coolant is stored in the right-hand end cavity 32. As the amount of coolant in the right-hand end cavity 32 increases, the coolant flows along multiple heat-conducting pipes 4 into the left-hand end cavity 32, and finally flows out along the left-hand first pipe joint 21. The upper second pipe joint 11 is located on the left, and the lower second pipe joint 11 is located on the right. The heat-conducting medium with a certain pressure enters the left cavity 311 along the upper second pipe joint 11. The heat-conducting medium in the left cavity 311 comes into contact with the outer wall of the heat-conducting pipe 4 on the inner side where the coolant is flowing, and the heat-conducting medium transfers heat to the left-hand end cavity 311. The heat from the heat pipe 4 is transferred to the coolant flowing inside. The coolant absorbs and carries away the heat from the heat pipe 4, thus reducing the heat of the heat transfer medium and cooling it. The cooled heat transfer medium enters through one end of the U-shaped outlet pipe 13 and then enters the hose 14 through the other end, finally exiting through the second pipe connector 11 located at the lower position. As the amount of heat transfer medium entering the left cavity 311 decreases, the pressure of the heat transfer medium in the left cavity 311 decreases. The increase in coolant in the right cavity 312 leads to an increase in pressure. The coolant in cavity 312 will push the regulating disc 5 to move to the left along the inner wall of the shell 1, thus reducing the space of the left cavity 311 and increasing the space of the right cavity 312. As the space of the left cavity 311 decreases, the space inside the left cavity 311 will adapt to the liquid volume of the heat transfer medium, so that the heat transfer medium in the left cavity 311 is always full and in contact with all the heat transfer pipes 4 in the left cavity 311, ensuring good heat conduction effect. As the right cavity 312 increases, it can store more coolant, preparing for the subsequent increase of heat transfer medium in the left cavity 311.As the amount of heat transfer medium entering the left cavity 311 increases, the pressure of the heat transfer medium in the left cavity 311 increases. This causes the regulating plate 5 to move to the right along the inner wall of the shell 1 under the push of the heat transfer medium in the left cavity 311. This makes the space in the left cavity 311 larger and the space in the right cavity 312 smaller. During the process of the space in the left cavity 311 increasing, the space in the left cavity 311 can adapt to the liquid volume of the heat transfer medium, so that the left cavity 311 can accommodate more heat transfer medium and ensure good heat transfer efficiency. During the process of the regulating plate 5 squeezing the coolant in the right cavity 312, the coolant in the right cavity 312 will be discharged into the right end cavity 32 along the connecting hole 33. The coolant in the right end cavity 32 will flow along the heat transfer pipe 4 and enter the left end cavity 32. Since the right cavity 312 has a large amount of coolant stored in advance, when the coolant in the left cavity 311 suddenly increases, the cooling in the heat exchange device... The liquid can be supplied in a timely manner, ensuring a good heat exchange effect. Furthermore, since the regulating disc 5 is slidably and sealed to the outer wall of the heat pipe 4, the regulating disc 5 can scrape away impurities adhering to the outer wall of the heat pipe 4, preventing impurities from affecting the heat conduction between the heat transfer medium and the heat pipe 4. This embodiment has a second method for moving the regulating disc 5. For example, an electric push rod (not shown in the figure) is installed in the right cavity 312 to control the movement of the regulating disc 5. Additionally, a flow sensor (not shown in the figure) is installed in the second pipe joint 11 on the left. The electric push rod drives the regulating disc 5 to move based on the data sensed by the flow sensor; this is the second driving method for the regulating disc 5. This invention uses the regulating disc 5 to be movably and sealed between the two end discs 3, thereby ensuring that the amount of heat transfer medium entering the inner side of the housing 1 is always adapted to the space, thus guaranteeing the contact quantity between the heat transfer medium and the heat pipe 4, and improving the heat exchange effect of the heat exchange device.

[0032] Example 2: The end plate 3 is rotatably and sealingly connected to the inner wall of the shell 1; the inner wall of the shell 1 is provided with a corrugated groove 15 along the axial direction; a corrugated block 16 is movably and sealingly connected in the corrugated groove 15; the corrugated block 16 is fixedly connected to the outer edge of the adjusting plate 5; the inner side of the U-shaped liquid outlet pipe 13 is rotatably and sealingly connected to the outer edge of the adjusting plate 5.

[0033] In this embodiment, the corrugated groove 15 has a span angle greater than 180 degrees in the circumferential direction of the inner wall of the shell 1; the corrugated groove 15 is staggered from the liquid outlet groove 12.

[0034] As the adjusting disc 5 moves left or right along the inner wall of the shell 1, it drives the corrugated block 16 to move along the corrugated groove 15. Since the corrugated groove 15 is corrugated on the inner wall of the shell 1 and spans the circumference of the inner wall, the corrugated block 16 moves back and forth along the circumference of the inner wall of the shell 1 as it moves along the corrugated groove 15. This causes the adjusting disc 5 to rotate clockwise and counterclockwise, thus causing it to move upwards along the axial direction of the shell 1 while simultaneously rotating back and forth. During this rotation, the adjusting disc 5 drives multiple heat pipes 4 to rotate inside the shell 1. During the rotation of the adjusting disk 5, the heat-conducting medium in the left cavity 311 can be agitated, so that more heat-conducting medium can come into contact with the heat-conducting pipe 4. After the heat-conducting medium is agitated, the contact area with the heat-conducting pipe 4 is increased, thereby improving the heat exchange efficiency between the heat-conducting medium and the coolant in the heat-conducting pipe 4. In addition, since the span angle of the corrugated groove 15 in the circumferential direction of the inner wall of the shell 1 is greater than 180 degrees, the heat-conducting pipe 4 located at the lower position on the inner side of the shell 1 can move to the upper position as the adjusting disk 5 rotates. With the expansion of the movement range of the heat-conducting pipe 4, the heat exchange effect between the heat-conducting pipe 4 and the heat-conducting medium is further improved.

[0035] Example 3: Baffles 6 are evenly distributed between the adjusting plate 5 and the left end plate 3; the baffles 6 are eccentrically provided with notches 61; the baffles 6 are in movable sealing contact with the inner wall of the shell 1; the notches 61 on adjacent baffles 6 are staggered and far apart from each other; the left end plate 3 and the baffles 6, adjacent baffles 6, and the baffles 6 and the adjusting plate 5 are all connected by a first spring 62; the heat pipe 4 passes through the baffles 6 and is slidably sealed to the baffles 6.

[0036] In this embodiment, the adjustment disk 5 is connected to the right end disk 3 by a second spring 51; the sum of the elastic forces of the first spring 62 on the left side of the adjustment disk 5 is balanced with the elastic force of the second spring 51 on the right side.

[0037] After the heat transfer medium enters the left cavity 311 at the left position, it flows towards the notch 61 on the first baffle 6 under the restriction of the first baffle 6. After passing through the notch 61 of the first baffle 6, the heat transfer medium enters the space between the first baffle 6 and the second baffle 6, then enters the space between the second baffle 6 and the third baffle 6 after passing through the notch 61 on the second baffle 6, and finally enters the U-shaped outlet pipe 13 after passing through the notch 61 on the last baffle 6. Since the notches 61 on adjacent baffle 6 are staggered and far apart from each other, the flow direction of the heat transfer medium in the left cavity 311 is from left to right and in a corrugated shape, thereby extending the flow path of the heat transfer medium in the left cavity 311 and further improving the heat exchange effect between the heat transfer medium and the heat transfer pipe 4; while adjusting During the movement of the disc 5 to the left or right inside the shell 1, for example, during the leftward movement of the adjusting disc 5, the adjusting disc 5 will compress the first spring 62, causing multiple first springs 62 to be compressed. During the rightward movement of the adjusting disc 5 inside the shell 1, the adjusting disc 5 will compress the second spring 51, causing multiple first springs 62 to unfold. The leftmost baffle 6 and the left end disc 3, the adjacent baffles 6, and the rightmost baffle 6 and the adjusting disc 5 maintain equidistant gaps. This extends the flow path of the heat transfer medium in the left cavity 311 on the one hand, and avoids interference between the baffles 6 and the adjusting disc 5 on the other hand. The presence of the second spring 51 is to counteract the elastic force exerted on the adjusting disc 5 by the first spring 62, so that the elastic force on both sides of the adjusting disc 5 is balanced, reducing the movement resistance of the adjusting disc 5 and improving the movement sensitivity of the adjusting disc 5.

[0038] Example 4: Multiple upper sealing blocks 17 are movably and sealingly connected within the corrugated groove 15; a lower sealing block 18 is slidably and sealingly connected within the liquid outlet groove 12; the upper sealing block 17 is inverted U-shaped, and the lower sealing block 18 is U-shaped; the number of upper sealing blocks 17 and lower sealing blocks 18 is the same as the number of baffles 6; the inner sides of the upper sealing blocks 17 and lower sealing blocks 18 are movably and sealingly connected to the outer edge of the baffles 6.

[0039] In this embodiment, the hose 14 is made of elastic material; a retainer 19 is fitted on the outer wall of the hose 14; the retainer 19 is slidably connected in the liquid outlet groove 12.

[0040] As the baffle 6 moves with the regulating plate 5, it drives the upper sealing block 17 and lower sealing block 18 on its outer edge to move. The upper sealing block 17 is movably and sealingly connected within the corrugated groove 15. Therefore, as the baffle 6 moves with the regulating plate 5, the upper sealing block 17 moves along the corrugated groove 15 to prevent the heat transfer medium from flowing along the corrugated groove 15. During its movement along the corrugated groove 15, the upper sealing block 17 can scrape away impurities adhering to the corrugated groove 15, ensuring its cleanliness and allowing the regulating plate 5 to move more smoothly. Additionally, since the lower sealing block 18 is movably and sealingly connected within the outlet groove 12, as the baffle 6 moves with the regulating plate 5, the lower sealing block 18 moves along the outlet groove 12 to prevent the heat transfer medium from flowing directly along the outlet groove 12 without being restricted by the baffle 6. During its movement along the outlet groove 12, the lower sealing block 18 can scrape away impurities within the outlet groove 12, causing them to be scraped out. Impurities on the surface of the heat pipe 4 will also be dislodged by the scraping of the baffle 6 and the adjusting plate 5. The impurities will flow into the hose 14 along the U-shaped outlet pipe 13 with the heat transfer medium, and finally be discharged along the second pipe joint 11 at the lower position. When the adjusting plate 5 moves left and right, it will drive the U-shaped outlet pipe 13 to move left and right synchronously. The U-shaped outlet pipe 13 will pull the hose 14 back and forth during the left and right movement, so that the hose 14 will be pulled back and forth. The impurities on the inside of the hose 14 will be loosened under the pull, so that the impurities in the hose 14 are not easy to block. Since the impurities in the heat pipe 4 are cleaned frequently, the amount of impurities flowing out of the hose 14 each time is small, and direct blockage will not occur. In addition, the heat transfer medium has a certain pressure to ensure that the impurities can be carried away with the heat transfer medium. In addition, the outer wall of the middle section of the hose 14 is slidably connected to the outlet groove 12 through the clamp 19. Therefore, when the hose 14 is restricted to approach the outlet groove 12, it is prevented from being touched by the rotation of the surrounding heat pipe 4, thus protecting the hose 14.

[0041] Example 5: The adjusting plate 5 is movably and sealed to the heat-conducting pipe 4 through the control hole 52; the adjusting plate 5 is composed of multiple adjusting sleeves 53 on the outer side and adjusting blocks 54 on the inner side; adjacent adjusting sleeves 53 are slidably and sealed; the innermost adjusting sleeve 53 is slidably and sealed to the adjusting block 54; the outer wall of the outermost adjusting sleeve 53 is fixedly connected to the corrugated block 16; the outermost adjusting sleeve 53 is movably and sealed to the U-shaped liquid outlet pipe 13; the control hole 52 is provided on the adjusting sleeves 53 and the adjusting blocks 54; the first spring 62 and the second spring 51 are connected to the outermost adjusting sleeve 53.

[0042] In this embodiment, the inner wall of the adjusting sleeve 53 is provided with an anti-detachment groove 55; an anti-detachment block 56 is slidably connected in the anti-detachment groove 55; the anti-detachment block 56 is fixedly connected to the inner adjusting sleeve 53; and the innermost anti-detachment block 56 is fixedly connected to the outer wall of the adjusting block 54.

[0043] When the amount of heat-conducting medium in the left cavity 311 changes slightly, such as a sudden increase, it will push the adjusting block 54 to the right. The adjusting block 54 will then sequentially cause multiple adjusting sleeves 53 to stagger. During the staggering process of the adjusting block 54 and the adjusting sleeves 53, the anti-detachment block 56 moves within the corresponding anti-detachment groove 55 to prevent adjacent adjusting sleeves 53 from detaching, and to prevent the innermost adjusting sleeve 53 from detaching from the adjusting block 54. This causes the originally flat surface of the adjusting plate 5 to become a bulging surface, increasing the contact area between the adjusting plate 5 and the coolant and heat-conducting medium. This makes it easier for the heat-conducting medium in the left cavity 311 to transfer heat through the adjusting plate 5 to the coolant in the right cavity 312. When the amount of heat-conducting medium in the left cavity 311 suddenly decreases, the regulating block 54 will move to the left. The leftward movement of the regulating block 54 will cause the regulating sleeve 53 to bulge to the left, and the regulating plate 5 to bulge to the left. Thus, the space in the left cavity 311 is occupied by the bulging regulating plate 5. In this embodiment, when there is a slight change in the flow rate in the left cavity 311, the space in the left cavity 311 can be adapted to the flow rate by directly adjusting the regulating plate 5 to bulge in two directions. This reduces the activity frequency of the regulating plate 5 and the baffle 6 due to the small change in the flow rate of the heat-conducting medium, thereby reducing activity noise and fatigue damage, and improving the user experience and service life of the heat exchange device.
