Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic cleaning equipment, and in particular to a temperature control device and a CNC ultrasonic cleaner for ultrasonic cleaning. Background Technology

[0002] The principle of an ultrasonic cleaner is that an ultrasonic generator emits a high-frequency oscillation signal, which is converted into high-frequency mechanical oscillations by an ultrasonic transducer and propagated into the cleaning fluid. When the ultrasonic transducer converts electrical energy into high-frequency mechanical vibration energy, some energy is dissipated as heat, causing the cleaning fluid temperature to rise. Simultaneously, tiny bubbles in the cleaning fluid are repeatedly compressed and expanded under the action of ultrasound, eventually bursting and releasing energy, generating localized high temperatures. As ultrasonic cleaning progresses, the temperature of the cleaning fluid gradually increases. When the CNC ultrasonic cleaner detects that the temperature of the cleaning solvent has reached a threshold, it will stop ultrasonic operation. To enable ultrasonic cleaners to operate continuously for extended periods, various ultrasonic cleaners with cooling functions have been developed in the current technology.

[0003] For example, the utility model patent "A Temperature-Controllable Ultrasonic Cleaning Machine" disclosed in the authorization announcement date of May 28, 2021, and authorization announcement number CN 213287947 U, includes a CNC ultrasonic cleaner and a cleaning basket. The ultrasonic cleaner is equipped with a cleaning tank, and the cleaning basket is placed inside the cleaning tank. A temperature control tube is installed on the inner wall of the cleaning tank, positioned between the bottom of the cleaning basket and the bottom surface of the cleaning tank. The water inlet port of the temperature control tube is connected to a water inlet control device to control the water inlet. This technical solution uses external circulating cooling water to cool the cleaning fluid, requiring a water supply tank, water pump, and return tank located in a refrigerator, and it also needs to be connected to a tap water pipe. Furthermore, the water pump's start and stop must be controlled based on a temperature sensor. This equipment is not only structurally complex but also cumbersome to operate. It requires a refrigerator, water pump, temperature sensor, PLC controller, and additional power supply. Moreover, the serpentine coil-type temperature control tube can only exchange heat with the cleaning fluid at the bottom of the cleaning tank. Additionally, once assembled, the entire system cannot be reused.

[0004] For example, the utility model patent CN 208261415 U, with an authorization announcement date of December 21, 2018, discloses a "Cooling Device for an Ultrasonic Cleaner." This device includes a cleaning tank, a shell, and a cleaning cover. The cleaning tank consists of an outer tank and an inner tank, with a temperature sensor installed on the side wall of the inner tank. A sandwich layer is formed between the outer and inner tanks. The ultrasonic cleaner also includes a cooling device comprising a cooling pipe, a reflux valve, a gas supply pipe, a recovery cylinder, a recovery check valve, a recovery pressure sensor, a reflux solenoid valve, a booster compressor, a reflux check valve, a gas supply cylinder, a gas supply solenoid valve, and a gas supply interface valve. Although this device uses a built-in cooling method, its structural complexity is far greater than that of a water-cooled external circulation cooling method. Furthermore, it still requires power to the booster compressor, solenoid valve, recovery pressure sensor, controller, and other electrical components. Additionally, this device uses liquid carbon dioxide for cooling and circulates it through a booster compressor, making the technology extremely complex and costly.

[0005] Therefore, how to cool down a CNC ultrasonic cleaner without increasing its structural complexity and energy consumption is a technical problem that urgently needs to be solved.

[0006] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of this utility model, and should not be regarded as an admission or in any form implying that the above technical information constitutes prior art known to those skilled in the art.

[0018] Based on the above technical solutions, as a preferred technical solution for the CNC ultrasonic cleaner, the cleaning tank is provided with a cover plate, and the lower surface of the cover plate is provided with a slot for positioning the aluminum alloy hollow plate.

[0019] This invention provides a temperature control device and a CNC ultrasonic cleaner for ultrasonic cleaning. Compared with traditional electronic control systems, this solution has a simplified structure, improved reliability, high flexibility, and reduced maintenance costs. The temperature control device for ultrasonic cleaning adopts a passive cooling design, utilizing the cold storage capacity of the phase change material encapsulated in an aluminum alloy hollow plate to cool the cleaning fluid inside the CNC ultrasonic cleaner. Due to the detachable design of the aluminum alloy hollow plate, it can be easily assembled and disassembled with the CNC ultrasonic cleaner. The aluminum alloy hollow plate can be replaced periodically, and the removed plate can be placed in a freezer for re-cold storage before future use. The temperature control device for ultrasonic cleaning provided by this invention not only simplifies the cooling structure of the CNC ultrasonic cleaner but also eliminates the need for additional energy consumption. It only requires periodic cold storage of the aluminum alloy hollow plate in any low-temperature environment such as a refrigerator or freezer, and the cooling operation is simple. In addition, the temperature control device provided by this utility model features a modular design of aluminum alloy hollow plates, which can be assembled into various shapes in the cleaning liquid. Each aluminum alloy hollow plate is also provided with through holes for the flow of cleaning liquid, which avoids the drawback of existing technologies that can only cool the outer wall of the cleaning tank. It can directly, uniformly and efficiently reduce the temperature of the cleaning liquid. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the core concept of the present utility model and the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

When a specific device is described as being located between a first device and a second device, an intermediary device may or may not be present between the specific device and the first or second device.

[0045] All terms used in this application have the same meaning as understood by one of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0046] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0047] A temperature control device for ultrasonic cleaning, such as Figures 1 to 7As shown, the device includes an aluminum alloy hollow plate 1 with a phase change material 2 internally encapsulated and thermally conductive fins 3 externally disposed. Specifically, the aluminum alloy hollow plate 1 contains the phase change material 2 for cold storage and heat absorption, which is isolated from the outside. Heat is transferred between the hollow plate body and the external thermally conductive fins 3, with the fins 3 accelerating the heat transfer. Preferably, the aluminum alloy hollow plate 1 is welded from aluminum alloy thin plates 11 with a thickness of 1-3 mm to form a hollow plate body with internal and external isolation.

[0048] Preferably, the heat-conducting fins 3 are also made of aluminum alloy sheet, welded to the hollow plate body, and respectively welded to two sides of the hollow plate body. The phase change material 2 filling the hollow plate body adopts existing technology, such as a hexadecane / graphene composite phase change material with a phase change temperature of 40±2℃, a latent heat of phase change of 180-220 J / g, and each 100 ml of phase change material can absorb approximately 18-22 kJ of heat, matching the ideal working temperature of the cleaning fluid. Of course, those skilled in the art can also select other suitable types of phase change materials based on the technical guidance of this embodiment.

[0049] The aluminum alloy hollow plate 1 has through holes 4 in its thickness direction for connecting the two sides, and a connector 5 for connecting to the CNC ultrasonic cleaner 10 is provided at the bottom of the aluminum alloy hollow plate 1. When the aluminum alloy hollow plate 1 is arranged in the ultrasonic cleaner 10 through the connector 5, the aluminum alloy hollow plate 1 can not only absorb heat through the heat-conducting fins 3 on both sides to reduce the temperature of the cleaning fluid, but also the cleaning fluid can flow between the two sides of the aluminum alloy hollow plate 1 through the through holes 4, which can fully improve the uniformity of cooling of the cleaning fluid and make the temperature of the cleaning fluid uniformly controlled.

[0050] The aluminum alloy hollow plate 1 has male connection structure 6 and female connection structure 7 on both sides for connecting adjacent aluminum alloy hollow plates 1. That is, the aluminum alloy hollow plate 1 in this embodiment is a modular structure, which can be used not only individually, but also in combination. Since each aluminum alloy hollow plate 1 has the same structure and includes an internal phase change material 2, an external heat-conducting fin 3, a bottom connector 5, and male connection structure 6 and female connection structure 7 on both sides, they can be connected in pairs in the cleaning fluid to form various shapes. This not only provides flexible arrangement and good cooling effect, but also enhances the stability of the connection with the CNC ultrasonic cleaner 10.

[0051] Thermal management mechanism description: When the ultrasonic waves raise the temperature of the cleaning solution, the phase change material changes from a solid to a liquid state, absorbing excess heat. Each 100ml of phase change material can absorb approximately 18-22kJ of heat, stabilizing the cleaning solution temperature within the phase change temperature range. After the ultrasonic waves stop, the hollow aluminum alloy plate 1 can be removed and replaced. The removed hollow aluminum alloy plate 1 is then transferred to a refrigerator for heat dissipation and cold storage. This solution completely eliminates the temperature sensor, control circuit, and heat dissipation device in traditional temperature control systems, simplifying the structure by more than 75%. Simultaneously, it ensures that the cleaning solution temperature automatically stabilizes within ±2℃, preventing interruption of ultrasonic operation and improving cleaning efficiency by 30-40%.

[0052] Based on the above embodiments, in a preferred embodiment of the temperature control device for ultrasonic cleaning, the aluminum alloy hollow plate 1 has a honeycomb-shaped cavity inside, and each cavity is encapsulated with a phase change material 2. Preferably, the thickness of the honeycomb-shaped cavity is 8-12 mm, and the honeycomb-shaped cavity and the internal phase change material 2 form a high thermal conductivity structure with a thermal conductivity >180 W / m·K, which can not only further improve the heat conduction effect, but also enhance the structural strength of the aluminum alloy hollow plate 1.

[0053] Based on the above embodiments, as a preferred embodiment of the temperature control device for ultrasonic cleaning, the connector 5 is either a strong magnetic structure 51 or a vacuum suction cup 52. This embodiment provides two types of connectors 5: one is a strong magnetic structure 51 that can be magnetically attached to any position in the stainless steel cleaning tank of the CNC ultrasonic cleaner 10; the other is a vacuum suction cup 52 that can be directly attached to any position in the stainless steel cleaning tank of the CNC ultrasonic cleaner 10 by pressing.

[0054] It should be noted that both the strong magnetic structure 51 and the vacuum suction cup 52 are common knowledge. This embodiment simply uses this mature existing technology without any special improvements, so its specific structure will not be described in detail. Nevertheless, in order to make this embodiment clearer and to facilitate public implementation, the following description is provided: the strong magnetic structure 51 can be a neodymium iron boron magnet, a samarium cobalt magnet, or an alnico magnet, etc., and the vacuum suction cup 52 can be a common conical rubber suction cup without a complicated vacuuming structure; it can be simply pressed onto a flat surface to achieve adsorption.

[0055] Based on the above embodiments, as a preferred embodiment of the temperature control device for ultrasonic cleaning, the phase change material 2 is a paraffin phase change material, a hydrated salt phase change material, or a graphene-based organic composite phase change material. This embodiment provides various types of phase change materials 2, intended to illustrate that the phase change material 2 embedded in the aluminum alloy hollow plate 1 can be selected from existing technologies and is not an invention of this application. This application merely utilizes these existing phase change materials 2 to achieve cold storage and heat absorption.

[0056] Nevertheless, to make this embodiment clearer and easier for the public to implement, the following description is provided: The wax phase change material can be hexadecane, octadecane, etc., which are non-corrosive and have low supercooling, with a phase change value of 150-220 kJ / kg; the hydrated salt phase change material can be disodium hydrogen phosphate dodecahydrate (Na2HPO4·12H2O), with a phase change temperature of about 40°C, which can be compounded with sodium acetate trihydrate to form a eutectic system for thermal management, with the advantage of dual-stage heat storage; the hydrated salt phase change material can be calcium chloride hexahydrate (CaCl2·6H2O), with a phase change temperature of 29°C and a latent heat of 191 J / g, close to the human body's comfortable temperature range, which can cause phase change earlier and control the temperature of the cleaning solution in advance; the graphene-based organic composite phase change material can be the aforementioned hexadecane / graphene composite phase change material.

This embodiment provides a preferred structural form of the heat-conducting fins 3, which are formed by crisscrossing horizontal fins 31 and vertical fins 32, and have two specific arrangement forms with the hollow plate body. One is that the horizontal fins 31 are directly welded to the hollow plate body, while the vertical fins 32 are welded to the side of the horizontal fins 31 away from the hollow plate body; the other is that the vertical fins 32 are directly welded to the hollow plate body, while the horizontal fins 31 are welded to the side of the vertical fins 32 away from the hollow plate body.

[0058] Based on the above embodiments, in a preferred embodiment of the temperature control device for ultrasonic cleaning, the through-hole 4 is a round hole, square hole, triangular hole, elliptical hole, or irregularly shaped hole, and a plurality of through-holes 4 are arranged in an array on the aluminum alloy hollow plate 1. This embodiment provides the specific shape and arrangement of the through-holes 4. Only one type of hole, such as round hole, square hole, triangular hole, elliptical hole, or irregularly shaped hole, is arranged on the aluminum alloy hollow plate 1. The irregularly shaped hole can be a hole with a polygonal projection or a hole with a smooth curve projection. Regardless of the type of through-hole selected, in addition to the array arrangement, other arrangement methods can also be selected, such as a quincunx pattern, a ring arrangement, etc.

[0059] Based on the above embodiments, as a preferred embodiment of the temperature control device for ultrasonic cleaning, the male connection structure 6 is a dovetail block 61 arranged in the vertical direction, and the female connection structure 7 is a dovetail groove 71 arranged in the vertical direction. When multiple aluminum alloy hollow plates 1 are used, adjacent aluminum alloy hollow plates 1 are connected by inserting dovetail blocks 61 into dovetail grooves 71.

[0060] Based on the above embodiments, as a preferred embodiment of the temperature control device for ultrasonic cleaning, the male connection structure 6 is a pin 62 arranged in the vertical direction, and the female connection structure 7 is a pin hole 72 arranged in the vertical direction. When multiple aluminum alloy hollow plates 1 are used, adjacent aluminum alloy hollow plates 1 are connected by inserting the pin 62 into the pin hole 72.

[0061] A type of CNC ultrasonic cleaner, such as Figures 8 to 11 As shown, it includes a numerical control unit connected to an ultrasonic transducer. The ultrasonic transducer is adapted to the cleaning tank 101 and includes the temperature control device for ultrasonic cleaning.

[0062] The width of the slot 103 is adapted to the size of the strong magnetic structure 51, or the width of the slot 103 is adapted to the thickness of the aluminum alloy hollow plate 1, which makes the connection between the aluminum alloy hollow plate 1 and the cleaning tank 101 more stable. The specific selection of the strong magnetic structure 102 can be the same as that of the strong magnetic structure 51, such as a neodymium iron boron magnet, a samarium cobalt magnet, or an alnico magnet. The specific selection of the vacuum suction cup 104 can be the same as that of the vacuum suction cup 52, i.e., a common conical rubber suction cup without a complex vacuum structure. When the aluminum alloy hollow plate 1 is pressed, the vacuum suction cup 52 and the vacuum suction cup 104 align with each other, and adsorption is completed when they are tightly fitted together.

The shape of the second slot 106 is the same as that of the first slot 103. When the cover plate 105 is engaged with the cleaning tank 101, the second slot 106 corresponds vertically to the first slot 103, ensuring that the aluminum alloy hollow plate 1 is in a vertical position.

[0064] Finally, it should be noted that the parts not described in detail in the above embodiments are all common knowledge known to those skilled in the art. For example, the connection method between the connector 5 and the hollow plate body can be by snap-fitting, bonding, etc.; the manufacturing method of the slot 1 103 and slot 2 106 can be by excavating grooves, or by using two spaced clamps; and so on.
