Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic technology and relates to an ultrasonic device with a cooling function. Background Technology

[0002] Ultrasonic equipment refers to equipment that uses ultrasound to pulverize, disperse, homogenize, and emulsify materials. Ultrasonic equipment includes, but is not limited to, ultrasonic cleaning equipment and ultrasonic pulverizing / dispersing / homogenizing / emulsifying equipment.

[0003] Ultrasonic pulverization is a technology that uses high-intensity ultrasonic energy to break down solid particles suspended in a liquid into finer particles. Its principle is based on the cavitation effect generated by ultrasound, which applies a strong impact to the particles, tearing and pulverizing them into smaller particles. In practical applications, by adjusting the frequency and pulse parameters of the ultrasound, precise control of nanoscale particle size can be achieved. The working principle of ultrasonic dispersion, homogenization, and emulsification equipment is similar; it also utilizes the cavitation effect to efficiently break down particles, droplets, or agglomerates in a liquid, thereby achieving uniform dispersion or emulsification.

[0004] When using ultrasonic equipment for pulverizing, dispersing, homogenizing, or emulsifying, the temperature of the liquid inside the container often rises continuously. This is due to unavoidable physical losses during the conversion of ultrasonic energy, such as the high temperature generated when cavitation bubbles collapse, and the heat generated by friction between liquid molecules caused by high-frequency ultrasound. In temperature-sensitive applications such as biopharmaceuticals and nanomaterials, temperature control of the liquid during ultrasonic processing is crucial. Excessive temperature can damage the material structure, such as protein denaturation, inactivation of active ingredients, decreased material properties, and even lead to runaway reactions or the formation of byproducts.

[0005] Existing designs typically employ liquid cooling pipes installed on the outside of the container to reduce the internal temperature through heat exchange. However, this cooling method is inefficient and has limited heat dissipation capacity, making it difficult to meet the temperature control requirements under high heat generation conditions. Therefore, there is still significant room for improvement in terms of cooling performance and applicability. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an ultrasonic device with a cooling function.

[0007] The objective of this utility model can be achieved through the following technical solution: an ultrasonic device with a cooling function, comprising:

[0008] A cooling pool, the interior of which has a cooling chamber and at least one working chamber, the cooling chamber surrounding each of the working chambers, the working chambers being isolated from the cooling chambers by a thermally conductive insulating member, and the bottom of the cooling pool having a base plate capable of transmitting mechanical vibrations;

[0009] An ultrasonic module is provided, the number of which is the same as the number of the working chambers and they are arranged in a one-to-one correspondence. The ultrasonic module is installed on the outer wall of the base plate, and the corresponding working chambers and ultrasonic modules are located on both sides of the same area of ​​the base plate. The ultrasonic module is configured to transmit ultrasonic waves from outside the cooling pool to the corresponding working chamber through a local area of ​​the base plate.

[0010] Preferably, the ultrasonic module includes a plurality of ultrasonic transducers, which are arranged in an array and are in close contact with the outer wall surface of the base plate.

[0011] Preferably, the isolation element is a hollow isolation cylinder, which is disposed in the cooling pool. The bottom of the isolation cylinder is sealed to the bottom plate. The interior of the isolation cylinder is the working chamber, and the isolation cylinder isolates the working chamber from the cooling chamber through its own cylinder wall.

[0012] Preferably, the isolation element is configured as a container, which is detachably disposed within the cooling pool, with the bottom of the container in contact with the bottom plate surface, and the interior of the container being the working chamber.

[0013] Preferably, it also includes a liquid cooling circulation mechanism, which includes an injection pipe and a drain pipe. The injection pipe passes through the wall of the cooling pool and communicates with the cooling cavity, and the drain pipe passes through the wall of the cooling pool and communicates with the cooling cavity.

[0014] Preferably, the liquid cooling circulation mechanism further includes a water pump, which is connected to the liquid injection pipe.

[0015] Preferably, the end of the injection pipe that passes through the cooling pool has an injection port, and the end of the drain pipe that passes through the cooling pool has a drain port. There is a height difference between the injection port and the drain port, and the distance between the drain port and the base plate is greater than the distance between the injection port and the base plate, so that when the coolant level in the cooling chamber reaches the height of the drain port, it is discharged through the drain pipe.

[0016] Preferably, the distance between the drain port and the base plate is less than the height of the working chamber.

[0017] Preferably, the system also includes material pipes, the number of which is the same as the number of working chambers and they are arranged in a one-to-one correspondence. The material pipes pass through the bottom plate and communicate with the working chambers.

[0018] Preferably, the base plate is made of metal.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. A working chamber is set directly inside the cooling pool, which is separated from the liquid cooling chamber. Coolant can be injected into the cooling chamber, so that the outside of the working chamber is filled with coolant, which greatly improves the heat exchange efficiency and heat dissipation capacity, and can meet the temperature control requirements under high heat generation conditions.

[0021] 2. The ultrasonic module and the working cavity correspond one-to-one through specific areas of the base plate to achieve precise directional energy transfer. The ultrasonic module can drive a local area of ​​the base plate to generate high-frequency mechanical vibration (ultrasonic energy). Since the base plate is located at the bottom of the working cavity, this high-frequency mechanical vibration can be transmitted into the working cavity, thereby achieving the ultrasonic treatment effect.

[0022] 3. The injection pipe is responsible for injecting the low-temperature coolant into the cooling chamber, and the drain pipe is responsible for leading out the coolant from the cooling chamber, thus forming a liquid cooling cycle. Preferably, the outflowing coolant returns to the cooling system for cooling, and then is reinjected into the cooling chamber through the injection pipe for reuse. Attached Figure Description

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1 to 4 As shown, an ultrasonic device with a cooling function includes:

[0030] The cooling pool 100 has a cooling chamber 110 and at least one working chamber 120 inside. The cooling chamber 110 surrounds each working chamber 120, and the working chamber 120 is isolated from the cooling chamber 110 by a thermally conductive insulating member 200. The bottom of the cooling pool 100 has a base plate 130 capable of transmitting mechanical vibration.

[0031] The number of ultrasonic modules 300 is the same as the number of working chambers 120 and they are arranged in a one-to-one correspondence. The ultrasonic modules 300 are installed on the outer wall of the base plate 130, and the corresponding working chambers 120 and ultrasonic modules 300 are located on both sides of the same area of ​​the base plate 130. The ultrasonic modules 300 are configured to transmit ultrasonic waves from outside the cooling pool 100 to the corresponding working chamber 120 through a local area of ​​the base plate 130.

[0032] The cooling tank 100 is designed as a water tank structure, which can be divided into a cooling chamber 110 and a working chamber 120. The exterior of each working chamber 120 is the cooling chamber 110. The function of the cooling chamber 110 is to contain the cooling medium (such as water, ethylene glycol solution, etc.) to remove the heat generated during the ultrasonic operation and maintain a stable internal temperature of the working chamber 120. Each working chamber 120 is an independent sealed cavity used to place the sample or material to be processed. The ultrasonic module 300 can apply ultrasonic energy to the working chamber 120 individually. The cooling chamber 110 and the working chamber 120 are separated by a thermally conductive insulating component 200 (such as an insulating cylinder or container) to ensure good heat conduction and avoid cross-contamination of liquids between the working chamber 120 and the cooling chamber 110.

[0033] Preferably, the base plate 130 is made of metal. Metal components can respond quickly and transmit vibration energy evenly, so the base plate 130 can effectively transmit the high-frequency mechanical vibration generated by the ultrasonic module 300 below to the working cavity 120 above.

[0034] The ultrasonic module 300 and the working cavity 120 correspond one-to-one through specific areas of the base plate 130 to achieve precise directional energy transfer. The ultrasonic module 300 can drive a local area of ​​the base plate 130 to generate high-frequency mechanical vibration (ultrasonic energy). Since the base plate 130 is located at the bottom of the working cavity 120, the high-frequency mechanical vibration can be transmitted into the working cavity 120, thereby achieving the ultrasonic treatment effect.

[0035] In the actual structure, the working chamber 120 and the ultrasonic module 300 are arranged vertically and vertically respectively. The ultrasonic module 300 is aligned with the bottom of the working chamber 120 through the base plate 130. When the ultrasonic module 300 is working, it can achieve precise directional energy transfer through the base plate 130. The ultrasonic treatment (crushing, dispersing, homogenizing, emulsifying) in the working chamber 120 and the liquid cooling circulation in the cooling chamber 110 operate synchronously. The coolant in the cooling chamber 110 directly removes the heat from the working chamber 120. Since the coolant in the cooling chamber 110 is in contact with the entire outer wall of the isolation component 200, it removes the heat from the working chamber 120 with the largest possible thermal contact area, greatly improving the heat exchange efficiency and heat dissipation capacity, and meeting the temperature control requirements under high heat generation conditions.

[0036] It is important to note that the ratio between the volume of coolant in the cooling chamber 110 and the total volume of all working chambers 120 is one of the key factors affecting the actual cooling effect. Simply put, with a fixed volume of all working chambers 120, the larger the volume of the cooling chamber 110, the more coolant it can hold, and the better the cooling effect. In the actual structure, the volume of a single working chamber 120 is smaller than that of the cooling chamber 110, while the total volume of all working chambers 120 is not much different from the volume of the cooling chamber 110, ensuring that the volume of coolant in the cooling chamber 110 can meet the cooling requirements of each working chamber 120.

[0037] In addition, there are multiple working chambers 120, each with a relatively small volume. The multiple small-volume working chambers 120 can increase the thermal contact area with the coolant, meaning that the material to be processed is evenly distributed into each working chamber 120. Although the volume of each working chamber 120 is small, the design of multiple working chambers 120 can meet the working requirements of large-capacity processing. Each working chamber 120 also exchanges heat with the surrounding coolant, greatly improving the heat dissipation and cooling effect.

[0038] To achieve the aforementioned dispersed heat dissipation effect, each working chamber 120 has a relatively small volume. If the ultrasonic module 300 (ultrasonic transducer) is directly placed into the working chamber 120, the effective working volume of the working chamber 120 will be greatly reduced. Therefore, the ultrasonic module 300 is specially arranged outside the working chamber 120, and the ultrasonic waves it generates are applied to the working chamber 120 through the base plate 130. In this way, the normal ultrasonic processing effect can be achieved without occupying the working volume of the working chamber 120.

[0039] In actual processing, different materials can be processed simultaneously in multiple working chambers 120, or the same materials can be processed simultaneously; moreover, each working chamber 120 can also be controlled independently, that is, a part of the working chamber 120 can be controlled to work separately.

[0040] In addition, the ultrasonic waves also generate heat when passing through the base plate 130, and the base plate 130 itself is a heat dissipation device, ensuring that the heat inside the equipment is dissipated through the base plate 130 after the process is completed and the ultrasonic equipment is stopped.

[0041] Based on the above embodiments, the ultrasonic module 300 includes a plurality of ultrasonic transducers 310, which are arranged in an array and are in close contact with the outer wall surface of the base plate 130.

[0042] The ultrasonic transducer 310 is the core component that converts electrical energy into high-frequency mechanical vibration (i.e., ultrasound). The array arrangement of the ultrasonic transducers 310 can improve the coverage area of ​​the ultrasound, enhance the uniformity of energy output, and improve the cavitation effect. The liquid / sample in the working chamber 120 is subjected to ultrasound, resulting in physical effects such as cavitation, emulsification, dispersion, and cleaning.

[0043] Example 1:

[0044] like Figure 1 , Figure 2 As shown, the isolation element 200 is a hollow isolation cylinder, which is placed inside the cooling pool 100. The bottom of the isolation cylinder is sealed to the bottom plate 130. The inside of the isolation cylinder is the working chamber 120. The isolation cylinder isolates the working chamber 120 from the cooling chamber 110 through its own cylinder wall.

[0045] In Embodiment 1, the isolation component 200 is fixed together with the cooling pool 100, and the bottom of the isolation cylinder is welded to the base plate 130, thereby forming a working chamber 120 inside the isolation cylinder, thus fixing the isolation cylinder and the base plate 130 together. The top of the isolation cylinder can be open (directly exposed to air) or sealed with a lid, depending on the actual application requirements. The cylinder wall acts as a physical barrier, strictly separating the working chamber 120 from the cooling chamber 110, while allowing heat to be conducted through the cylinder wall. In actual operation, the outer circumferential surface of the isolation cylinder is in contact with a large amount of coolant, that is, the isolation cylinder is immersed in coolant, thereby achieving a highly efficient heat dissipation effect.

[0046] Example 2:

[0047] The isolation component 200 is configured as a container, which is detachably installed in the cooling pool 100. The bottom of the container is in surface contact with the bottom plate 130, and the interior of the container is the working chamber 120.

[0048] In Embodiment 2, the isolation component 200 is designed as an independent container that can be placed into or removed from the cooling pool 100 as a whole. The bottom of the container is in full contact with the bottom plate 130 to ensure that vibration energy is transmitted without loss.

[0049] Embodiment 1 and Embodiment 2 provide two structural designs for isolating the working chamber 120 and the cooling chamber 110, respectively. The main purpose is to ensure that the working chamber 120 and the cooling chamber 110 do not come into direct contact through physical isolation while achieving heat conduction. Embodiment 1 is a fixed structure, with the isolation cylinder and cooling pool 100 integrated into one design; Embodiment 2 is a modular, detachable structure, where the container can be removed as a whole.

[0050] like Figures 1 to 3 As shown, based on the above embodiment, a liquid cooling circulation mechanism is also included. The liquid cooling circulation mechanism includes an injection pipe 400 and a drain pipe 500. The injection pipe 400 passes through the wall of the cooling pool 100 and communicates with the cooling chamber 110. The drain pipe 500 passes through the wall of the cooling pool 100 and communicates with the cooling chamber 110.

[0051] The injection pipe 400 is responsible for injecting low-temperature coolant into the cooling chamber 110, and the drain pipe 500 is responsible for draining the coolant from the cooling chamber 110, thereby forming a liquid cooling cycle. Preferably, the outflowing coolant returns to the cooling system for cooling, and then is reinjected into the cooling chamber 110 through the injection pipe 400 for reuse.

[0052] Based on the above implementation, the liquid cooling circulation mechanism also includes a water pump 410, which is connected to the liquid injection pipe 400. The water pump 410 provides a constant pressure to achieve active liquid cooling circulation in the cooling chamber 110. Furthermore, a temperature sensor is installed in the working chamber 120. When the temperature rises sharply, the system controls the water pump 410 to run at high speed; when the temperature is slightly higher than a preset threshold, the system controls the water pump 410 to run at low speed; when the temperature is less than (or equal to) the preset threshold, the system controls the water pump 410 to stop running. Based on the temperature parameters transmitted back from the temperature sensor, the system can accurately control the flow rate and velocity of the coolant to adapt to different heat load conditions.

[0053] Based on the above implementation method, the end of the injection pipe 400 that passes through the cooling pool 100 has an injection port, and the end of the drain pipe 500 that passes through the cooling pool 100 has a drain port. There is a height difference between the injection port and the drain port. The distance between the drain port and the bottom plate 130 is greater than the distance between the injection port and the bottom plate 130, so that when the coolant level in the cooling chamber 110 reaches the height position of the drain port, it is discharged through the drain pipe 500.

[0054] The drain port is higher than the injection port, which means that coolant is injected from near the bottom of the cooling pool 100 (cooling chamber 110). When the coolant level reaches a certain height, the coolant flows out from the higher drain port, thus achieving an automatic overflow effect. This overflow control mechanism based on height difference is one of the core designs of the liquid cooling circulation system.

[0055] Based on the above implementation method, the distance between the drain port and the bottom plate 130 is less than the height of the working chamber 120.

[0056] This design ensures that the coolant level remains stable at the height of the drain port and is always below the top of the working chamber 120 (container or isolation cylinder), ensuring that the coolant cannot flow into the working chamber 120 from the top opening, while covering the entire or most area of ​​the outer wall of the main body of the working chamber 120.

[0057] like Figures 1 to 4 As shown, based on the above embodiment, it also includes a material pipe 600. The number of material pipes 600 is the same as the number of working chambers 120 and they are arranged in a one-to-one correspondence. The material pipes 600 pass through the bottom plate 130 and communicate with the working chambers 120.

[0058] The material pipe 600 can inject the material to be processed into the working chamber 120, and after processing, the material is discharged through the material pipe 600, which facilitates the loading and unloading process and continuous production.

[0059] It should be noted that, based on Embodiment 1, since the isolation cylinder is welded to the base plate 130, the isolation cylinder cannot be removed. The material pipe 600 can effectively solve the problem of inconvenient loading and unloading in the isolation cylinder design.

[0060] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0061] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
