Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a self-cleaning and scale-preventing heat exchanger for mold temperature controllers. Background Technology

[0002] The heat exchanger installed in the mold temperature controller is a plate heat exchanger, which is a high-efficiency heat exchanger composed of a series of metal plates with a certain corrugated shape. Thin rectangular channels are formed between the plates, through which heat exchange occurs. Plate heat exchangers are ideal devices for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. The main types of plate heat exchangers are frame type (detachable) and brazed type, and the plate types are mainly herringbone corrugated plates, horizontal straight corrugated plates, and dovetail plates.

[0003] Patent document CN219674885U discloses a plate heat exchanger "including a fixed clamping plate, with guide rods fixedly installed at the top and bottom of the rear side of the fixed clamping plate by bolts, and guide rod brackets fixedly installed at the ends of the guide rods by bolts. Plates and a movable clamping plate are slidably installed between the guide rods, and the fixed clamping plate and the movable clamping plate are fixed on both sides by fastening bolts and nuts. This utility model of a plate heat exchanger, through the guide rod composed of a main rod, connecting rod, and end rod, facilitates installation and disassembly, and is easy to operate. When the number of plates is small, the overall length of the guide rod can be shortened by removing the connecting rod, reducing the overall volume, while still meeting the installation requirements of different numbers of plates, providing high flexibility and facilitating the installation and disassembly of plates." The plate heat exchanger in the patent document solves the problem of the inconvenience of plate installation and disassembly in existing heat exchangers. However, scale will form on the surface of the plates in this heat exchanger after long-term use. If the scale is not effectively cleaned, it will affect the heat transfer effect of the plates.

[0004] In view of this, the present invention proposes a self-cleaning anti-scaling heat exchanger for mold temperature controllers, which can conveniently clean the scale generated on the outside of the plates. Utility Model Content

[0005] To address the problem of inconvenience in cleaning scale buildup on the outside of heat-conducting plates in existing technologies, this invention provides a self-cleaning anti-scaling heat exchanger for mold temperature controllers.

[0006] The technical solution adopted in this utility model is:

[0007] A self-cleaning anti-scaling heat exchanger for a mold temperature controller includes a first frame plate. Mounting rods are symmetrically installed on the inner side of the first frame plate. Several neatly arranged heat-conducting plates are mounted on the inner side of the first frame plate via the mounting rods. An ultrasonic descaling assembly is integrated on one side of each heat-conducting plate. The ultrasonic descaling assembly includes an integrated groove, a positioning groove, and an ultrasonic descaling mechanism. The integrated groove is located on one side of the heat-conducting plate, and multiple positioning grooves are formed on the inner wall of the positioning groove. The ultrasonic descaling mechanism is integrated inside the integrated groove.

[0008] Preferably, the ultrasonic descaling mechanism includes an installation layer, an ultrasonic generator, a protective layer, a sealing layer, and a piezoelectric ceramic sheet. The ultrasonic generator is installed inside the installation layer, the protective layer is installed outside the installation layer, the sealing layer is installed inside the installation layer, and the piezoelectric ceramic sheet is installed inside the sealing layer, with the piezoelectric ceramic sheet protruding from the inside of the sealing layer.

[0009] Preferably, sealing gaskets are symmetrically installed on the front and back sides of the heat-conducting plate, and through holes are opened on the four outer corners of the heat-conducting plate.

[0010] Preferably, a plurality of connecting screws are installed through the outer side of the first frame plate, and a second frame plate is installed on one side of the first frame plate via the connecting screws, and the second frame plate is located on one side of the heat-conducting plate.

[0011] Preferably, the bottom of the first and second shelves are symmetrically equipped with support legs.

[0012] Preferably, a first inlet is installed through one side of the back of the first shelf, a first outlet is installed below the first inlet on one side of the back of the first shelf, a second inlet is installed through one side of the front of the first shelf, and a second outlet is installed through one side of the front of the first shelf, with the first inlet, the first outlet, the second inlet and the second outlet corresponding to the through hole.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, scale and other dirt will accumulate on the surface of the heat-conducting plate after prolonged use. To facilitate the cleaning of scale, an ultrasonic descaling mechanism is encapsulated and integrated inside an integrated groove, thus integrating the ultrasonic descaling mechanism onto the heat-conducting plate. The piezoelectric ceramic sheet inside the sealing layer is connected to the ultrasonic generator, using electromagnetic induction to achieve energy conversion. This allows the piezoelectric ceramic sheet to convert high-frequency signals into mechanical vibrations, which in turn cause the heat-conducting plate to vibrate, enabling the scale on the outside of the heat-conducting plate to be cleaned and peeled off, making the cleaning of the heat-conducting plate more convenient. The sealing layer is used to seal the installation of the piezoelectric ceramic sheet. The sealing layer is made of copper and has a good heat dissipation structure. The protective layer is made of stainless steel and is used to protect the outside of the installed ultrasonic descaling mechanism from external corrosion. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example

[0022] A self-cleaning anti-scaling heat exchanger for a mold temperature controller includes a first frame plate 1. Mounting rods 9 are symmetrically installed on the inner side of the first frame plate 1. Several neatly arranged heat-conducting plates 10 are installed on the inner side of the first frame plate 1 via the mounting rods 9. An ultrasonic descaling component is integrated on one side of the heat-conducting plates 10. The ultrasonic descaling component includes an integrated groove 13, a positioning groove 14, and an ultrasonic descaling mechanism 15. The integrated groove 13 is opened on one side of the heat-conducting plates 10. Multiple positioning grooves 14 are opened on the inner wall of the positioning groove 14. The ultrasonic descaling mechanism 15 is integrated and installed inside the integrated groove 13.

[0023] The first support plate 1 and the second support plate 3 are made of stainless steel and are used to support the entire heat exchanger mechanism. They also provide a location for the mounting rod 9, which supports the heat-conducting plate 10. The mounting rod 9 is located at the top and bottom of the heat-conducting plate 10, respectively, providing support between the first support plate 1 and the second support plate 3. The heat-conducting plate 10 is made of stainless steel, commonly 304 or 316L, and is suitable for media with low chloride ion content such as water, edible oil, and mineral oil. The heat-conducting plate 10 has a corrugated design; through the close arrangement of the metal plates and the corrugated structure, it achieves high-temperature medium... Rapid heat transfer between the medium and the low-temperature medium is achieved through a corrugated design that significantly increases fluid turbulence and improves heat transfer efficiency. At the same time, the surface of the heat-conducting plate 10 is coated with a hydrophobic and oleophobic coating to reduce the adhesion of impurities. After prolonged use, scale and other dirt will accumulate on the surface of the heat-conducting plate 10. To facilitate the cleaning of scale from the heat-conducting plate 10, an ultrasonic descaling mechanism 15 is encapsulated and integrated inside the integrated groove 13. This allows the ultrasonic descaling mechanism 15 to be integrated into the heat-conducting plate 10 for use. The ultrasonic descaling mechanism 15 generates high-frequency vibrations, which cause the scale on the outside of the heat-conducting plate 10 to peel off and then be discharged through the flowing water.

[0024] The ultrasonic descaling mechanism 15 includes a mounting layer 16, an ultrasonic generator 17, a protective layer 18, a sealing layer 19, and a piezoelectric ceramic sheet 20. The ultrasonic generator 17 is installed inside the mounting layer 16, the protective layer 18 is installed outside the mounting layer 16, the sealing layer 19 is installed inside the mounting layer 16, and the piezoelectric ceramic sheet 20 is installed inside the sealing layer 19, with the piezoelectric ceramic sheet 20 protruding from the inside of the sealing layer 19.

[0025] Mounting layer 16 provides a location for the installation of ultrasonic generator 17. Ultrasonic generator 17 consists of signal generation circuit, power amplification circuit, power management, remote control system, power adjustment and integrated circuit board. Piezoelectric ceramic plate 20 located inside sealing layer 19 is connected to ultrasonic generator 17. It uses electromagnetic induction to realize energy conversion, so that piezoelectric ceramic plate 20 converts high frequency signal into mechanical vibration, which drives heat conduction plate 10 to vibrate, so that the scale on the outside of heat conduction plate 10 can be cleaned and peeled off, making it easier to clean heat conduction plate 10. Sealing layer 19 is used to seal the installation of piezoelectric ceramic plate 20. Sealing layer 19 is made of copper and has a good heat dissipation structure. Protective layer 18 is made of stainless steel corrosion-resistant material and is used to protect the outside of the installed ultrasonic descaling mechanism 15 from external corrosion.

[0026] Sealing gaskets 12 are symmetrically installed on the front and back sides of the heat-conducting plate 10, and through holes 11 are opened on the four outer corners of the heat-conducting plate 10.

[0027] During installation, the heat-conducting plates 10 are separated by sealing gaskets 12 installed on the outside, forming rectangular channels between the heat-conducting plates 10 and creating gaps between them. The sealing gaskets 12 are made of EPDM rubber, which is resistant to temperatures of 110-180 degrees Celsius and is suitable for media such as hot water and steam. The through holes 11 allow the added medium to exchange heat through each heat-conducting plate 10.

[0028] Multiple connecting screws 2 are installed through the outer side of the first frame plate 1. A second frame plate 3 is installed on one side of the first frame plate 1 through the connecting screws 2, and the second frame plate 3 is located on one side of the heat conduction plate 10.

[0029] The first frame plate 1 and the second frame plate 3 are installed together by connecting screws 2. The connecting screws 2 are made of stainless steel and are fixed by nuts. The first frame plate 1 and the second frame plate 3 clamp the inner heat-conducting plate 10.

[0030] Support legs 4 are symmetrically installed at the bottom of the first frame 1 and the second frame 3;

[0031] The support leg 4 is made of the same material as the first frame plate 1 and the second frame plate 3. The support leg 4 is used to support the first frame plate 1 and the second frame plate 3 from the bottom. The support leg 4 is fixed by bolts, so that the heat exchanger is fixed inside the mold temperature controller for use.

[0032] A first inlet 5 is installed through one side of the back of the first shelf 1. A first outlet 6 located below the first inlet 5 is installed through one side of the back of the first shelf 1. A second inlet 7 is installed through one side of the front of the first shelf 1. A second outlet 8 located below the second inlet 7 is installed through one side of the front of the first shelf 1. The first inlet 5, the first outlet 6, the second inlet 7 and the second outlet 8 are respectively corresponding to the through hole 11.

[0033] The first inlet 5 allows high-temperature water to enter the heat exchanger. After passing through the heat-conducting plate 10, the water exits through the first outlet 6 located at the bottom. Simultaneously, the second inlet 7 allows low-temperature water to enter the heat exchanger. After passing through the heat-conducting plate 10, the water exits through the second outlet 8 located at the bottom. When hot and cold water flow simultaneously inside, the hot and cold fluids flow through the channels on both sides of the plate, respectively. The heat-conducting plate 10 in the middle layer facilitates heat transfer, allowing heat to be conducted from the high-temperature fluid to the low-temperature fluid, thus achieving thermal equilibrium.

[0034] Working principle: First, the heat exchanger is installed in the mold temperature controller via the support leg 4. During operation, hot and cold fluids enter through the first inlet 5 and the second inlet 7 respectively, exchange heat through the channels between the heat-conducting plates 10, and finally exit through the first outlet 6 and the second outlet 8. Over time, scale will accumulate on the outer side of the heat-conducting plates 10. The ultrasonic descaling mechanism 15 is activated remotely. The ultrasonic generator 17 in the ultrasonic descaling mechanism 15 causes the piezoelectric ceramic sheet 20 to vibrate at high frequency, thereby causing the heat-conducting plates 10 to vibrate and peel off the scale, which is then discharged through the water flow. To ensure proper operation, the sealing layer 19 is made of copper with a good heat dissipation structure, and the protective layer 18 is made of stainless steel for corrosion protection, preventing external corrosion of the ultrasonic descaling mechanism 15 and allowing it to be better installed inside the heat-conducting plates 10.

[0035] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
