[0002] This application claims priority to Chinese patent application filed on January 24, 2025, with application number 202510117767.0, entitled "Metal Bath Module and Metal Bath Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of scientific research equipment technology, and in particular to metal bath components and metal bath devices. Background Technology

[0004] A metal bath is a temperature control device that uses metal as the heat transfer medium. It utilizes the excellent thermal conductivity of metal to uniformly transfer heat to the sample, thereby achieving heating, cooling, or temperature maintenance. Due to its excellent temperature uniformity, wide temperature range, and rapid heating speed, metal baths are widely used in biochemistry, medical testing, and materials science.

[0005] Metal baths typically employ a heat pump to heat or cool a metal heat-conducting block, and a heat dissipation assembly to cool the heated component. In related technologies, the heat dissipation assembly usually consists of a cooling fan and heat sinks. However, this heat dissipation assembly has low efficiency in heating and cooling the heated component, and is prone to heat short-circuiting and internal dissipation in the small environment surrounding the metal bath assembly. Furthermore, both the cooling fan and heat sink need to be mounted on the metal bath assembly, resulting in a large thickness and projected area, which is detrimental to the installation and integration of the metal bath assembly with other workbenches in automated experimental processes.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0051] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0052] Referring to Figures 1 and 2, which show exploded structural diagrams of a metal bath device 10 according to an embodiment of this application, the metal bath device 10 provided in this embodiment is used for heating or maintaining a constant temperature of a sample. As shown in Figure 1, the metal bath device 10 includes a metal bath assembly 100 as described in any of the following embodiments, and the number of metal bath assemblies 100 is multiple. In the embodiment shown in Figure 1, four metal bath assemblies 100 are illustrated as an example, but this is not a limitation, and the number of metal bath assemblies 100 may be more or less.

[0053] Referring to Figures 3 and 4, Figure 3 shows an exploded structural diagram of the metal bath assembly 100 in one embodiment of this application, and Figure 4 shows a cross-sectional schematic diagram of the metal bath assembly 100 in one embodiment of this application. The metal bath assembly 100 provided in one embodiment of this application is used for heating or maintaining a constant temperature of a sample.

[0054] As shown in Figures 3 and 4, the metal bath assembly 100 includes a metal base 110, a temperature control element 120, and a heat dissipation element 130. The metal base 110 is a thermally conductive metal component, which is used to receive the heat from the temperature control element 120 and transfer the heat to the sample, thereby achieving heating or constant temperature maintenance of the sample.

[0055] As shown in Figures 1 and 2, the metal bath device 10 also includes an adapter 800. Each metal bath assembly 100 is connected to an adapter 800, and the adapter 800 is connected to the end face of the corresponding metal base 110 facing away from the temperature control element 120. The adapter 800 is used to place samples of different sizes. As shown in Figures 1 and 2, the structures of the adapters 800 connected to different metal bath assemblies 100 do not interfere with each other, and the structures of the adapters 800 can be the same or different.

[0056] As shown in Figures 3 and 4, the temperature control element 120 is located on one side of the metal base 110 and acts on the metal base 110 to heat or cool it. In this embodiment, the temperature control element 120 is located below the metal base 110. In this embodiment, the temperature control element 120 is a semiconductor cooling chip, which can realize both cooling and heating functions. When the side of the temperature control element 120 near the metal base 110 is heated, the side away from the metal base 110 will cool down. Conversely, when the side of the temperature control element 120 near the metal base 110 is cooled, the side away from the metal base 110 will heat up. It is understood that the temperature control element 120 and the metal base 110 can be attached together for direct contact, or they can be connected by thermally conductive materials such as thermally conductive adhesive. As long as the temperature control element 120 and the metal base 110 are thermally conductively connected, the connection method between the temperature control element 120 and the metal base 110 is not limited.

[0057] As shown in Figures 3 and 4, the heat sink 130 is located on the side of the temperature control element 120 opposite to the metal base 110. In this embodiment, the heat sink 130 is located below the temperature control element 120. It is understood that the temperature control element 120 and the heat sink 130 can be directly contacted by being fitted together, or they can be connected by thermally conductive materials such as thermally conductive adhesive. The connection between the temperature control element 120 and the heat sink 130 is not limited, as long as they are thermally conductive. The heat sink 130 is made of a thermally conductive material to allow for heat exchange with the temperature control element 120.

[0058] As shown in Figures 4 and 6, the heat sink 130 has a liquid flow channel 133 inside for liquid flow, and the upstream and downstream of the liquid flow channel 133 are respectively connected to the outside, so that the liquid in the liquid flow channel 133 can flow in from the outside and flow out to the outside. It should be noted that in this specification, water is used as an example of liquid, but this is not a limitation, and the liquid can also be other coolants.

[0059] In this embodiment, the liquid flow channel 133 is connected to an external circulating water source so that the water in the liquid flow channel 133 circulates continuously, thereby improving the heat absorption or release efficiency of the heat sink 130 to the temperature control element 120. In some embodiments, a cooling fan or the like can also be provided on the flow path between the circulating water source and the liquid flow channel 133 to allow the liquid inside the liquid flow channel 133 to recover to the set temperature as quickly as possible after absorbing or cooling heat.

[0060] The metal bath assembly 100 provided in the above embodiments achieves heat exchange with the temperature control component 120 by setting a liquid flow channel 133 inside the heat sink 130. Compared with the air cooling used in related technologies, it can achieve more heat exchange through direct heat conduction, which has a more efficient heating and cooling efficiency. At the same time, it also overcomes the problem of large space required by air cooling technology, which requires the configuration of heat dissipation fans and heat dissipation fins. The metal bath assembly 100 has a smaller volume and can be more conveniently installed and cooperated with other workbenches in the automated experimental process, which facilitates the integration and installation of various components in the automated experimental process.

[0061] As shown in Figure 6, in one embodiment, the liquid flow channel 133 includes a meandering section 1331. As shown in Figure 6, the meandering section 1331 includes multiple bends 13310 connected end-to-end. Each bend 13310 includes an upstream portion 13311 and a downstream portion 13312 that are angled together and connected, so that the liquid flow channel 133 covers as much area as possible of the heat sink 130, and the liquid in the liquid flow channel 133 contacts as much of the sidewall of the liquid flow channel 133 as possible, thereby making the heat exchange between the liquid and the heat sink 130 more efficient. In this embodiment, the upstream portion 13311 and the downstream portion 13312 are arranged perpendicularly. In other embodiments, the angle between the upstream portion 13311 and the downstream portion 13312 may also be an acute angle or an obtuse angle.

[0062] As shown in Figure 6, the liquid flow channel 133 also includes an inlet section 1332 and an outlet section 1333 located at both ends of the detour section 1331. After the liquid enters the liquid channel, it passes through the inlet section 1332, the detour section 1331 and the outlet section 1333 in sequence and then flows out of the liquid channel. During the flow, the liquid absorbs the heat from the heat sink 130, causing the temperature of the heat sink 130 to change towards the temperature of the liquid, thereby achieving cooling or heating of the heat sink 130.

[0063] As shown in Figure 7, in one embodiment, the liquid flow channels 133 in each metal bath assembly 100 are interconnected, so that the liquid flow channels 133 of different metal bath assemblies 100 located in the same metal bath device 10 can be connected to the outside through the same inlet 220 and the same outlet 240. This allows the liquid flow channels 133 of different metal bath assemblies 100 to be connected to the same external water source, thereby enabling unified control of the flow rate and other parameters of the liquid flow channels 133 of different metal bath assemblies 100. It also makes it easier to add or remove metal bath assemblies 100 from the metal bath device 10 without having to reconnect to the external circulating water source when adding or removing metal bath assemblies 100. It is understood that when the heat generated by the temperature control element 120 in different metal bath assemblies 100 is different, the interconnected liquid flow channels 133 can also neutralize the heat of the liquid, making the heat of the liquid more uniform. In other embodiments, the liquid flow channels 133 of the metal bath assemblies 100 may also be unconnected for independent control, or partially connected for zoned control.

[0064] As shown in Figures 1 and 2, in one embodiment, all metal bath components 100 are disposed on the same plane. In this embodiment, all metal bath components 100 are arranged horizontally. In other embodiments, the metal bath components 100 may also adopt other arrangements.

[0065] Adjacent metal bath assemblies 100 are spaced apart, as shown in Figures 1 and 2. The water receiving trays 150 of adjacent metal bath assemblies 100 are also spaced apart to avoid interference between them when the temperatures of adjacent metal bath assemblies 100 are different.

[0066] As shown in Figure 7, in one embodiment, the water inlet sections 1332 of adjacent metal bath assemblies 100 are coaxially and interconnected to form a water inlet main pipe 210, and the water outlet sections 1333 of adjacent metal bath assemblies 100 are coaxially and interconnected to form a water outlet main pipe 230. The water inlet main pipe 210 and the water outlet main pipe 230 are respectively connected to the outside.

[0067] As shown in Figure 7, the inlet sections 1332 of adjacent metal bath assemblies 100 are connected by a connecting pipe 250, so that the inlet sections 1332 and the connecting pipes 250 connected to the inlet sections 1332 together form the main inlet pipe 210. In this embodiment, the main inlet pipe 210 is a straight pipe. The metal bath device 10 has an inlet 220 that communicates with the main inlet pipe 210, so that the liquid flow channel 133 is connected to the outside.

[0068] As shown in Figure 7, the outlet sections 1333 of adjacent metal bath assemblies 100 are connected by a connecting pipe 250, so that the outlet sections 1333 and the connecting pipe 250 connected to the outlet sections 1333 together form the main outlet pipe 230. In this embodiment, the main outlet pipe 230 is a straight pipe. The metal bath device 10 has an outlet 240 that communicates with the main outlet pipe 230, so that the liquid flow channel 133 is connected to the outside.

[0069] Obviously, the metal bath device 10 can also include more metal bath components 100. It is only necessary to connect the inlet section 1332 of different metal bath components 100 to the inlet section 1332 of adjacent metal bath components 100 through the connecting pipe 250, and connect the outlet section 1333 of different metal bath components 100 to the outlet section 1333 of adjacent metal bath components 100 through the connecting pipe 250. This makes it easy to install more metal bath components 100 in the metal bath device 10, thereby realizing a high-throughput and highly integrated hot and cold metal bath platform.

[0070] As shown in Figure 8, in this embodiment, the outlet 240 and inlet 220 are each equipped with a quick-connect plug 700 to facilitate quick disconnection of the metal bath device 10 from the external water source, enabling easier installation of the metal bath device 10 at different locations on other workbenches in the automated experimental process. In this embodiment, the quick-connect plug 700 has a bidirectional water-stopping structure inside, ensuring that when the quick-connect plug 700 is disconnected, water from both the external water source and the liquid flow channel 133 will not flow out, further facilitating the disassembly and relocation of the metal bath device 10.

[0071] In one embodiment, the cross-sectional area of ​​the main inlet pipe 210 perpendicular to its axial direction is larger than the cross-sectional area of ​​the meandering section 1331 perpendicular to its axial direction. This reduces the difference in frictional resistance between the meandering section 1331 and the inlet 220 when liquid enters each meandering section 1331, reduces the influence of fluid inertial force, and plays a role in uniformly distributing pressure. This ensures that the water pressure flowing into the meandering section 1331 from different metal bath components 100 is relatively consistent, thereby ensuring uniform flow and making the heat transfer effect of the heat sink 130 of each metal bath component 100 stable and efficient. In this embodiment, the cross-sectional area of ​​the main inlet pipe 210 perpendicular to its axial direction is twice or more the cross-sectional area of ​​the meandering section 1331 perpendicular to its axial direction.

[0072] In one embodiment, the cross-sectional area of ​​the main outlet pipe 230 perpendicular to its axial direction is larger than the cross-sectional area of ​​the meandering section 1331 perpendicular to its axial direction. This reduces the difference in frictional resistance between the meandering section 1331 and the outlet 240 when liquid flows out of each meandering section 1331, reduces the influence of fluid inertial force, and plays a role in uniformly distributing pressure. This ensures that the water pressure is relatively consistent when flowing out of the meandering sections 1331 in different metal bath components 100, thereby ensuring uniform flow and making the heat transfer effect of the heat sink 130 of each metal bath component 100 stable and efficient. In this embodiment, the cross-sectional area of ​​the main outlet pipe 230 perpendicular to its axial direction is twice or more the cross-sectional area of ​​the meandering section 1331 perpendicular to its axial direction.

[0073] As shown in Figure 4, in one embodiment, the plane containing the central axis of the meandering section 1331 is parallel to the plane containing the temperature control element 120, so that the heat conduction distance between the liquid flow channel 133 and the temperature control element 120 is consistent at all points, avoiding the influence of different heat conduction distances on the heat dissipation uniformity of the heat sink 130. In other embodiments, the meandering section 1331 may also be arranged at an angle to the plane containing the temperature control element 120, without limitation.

[0074] As shown in Figure 9, in one embodiment, the metal base 110 includes a support portion 111 and a heat-conducting portion 112 connected to each other. The heat-conducting portion 112 extends from the support portion 111 toward the temperature control element 120, and is aligned with the temperature control element 120 so that the temperature of the temperature control element 120 is transferred to the support portion 111 through the heat-conducting portion 112. In this embodiment, the support portion 111 and the heat-conducting portion 112 are an integral structure.

[0075] In one embodiment, there are multiple temperature control elements 120, each located on the same side of the metal base 110 and in the same plane. Adjacent temperature control elements 120 are spaced apart to avoid interference. A heat-conducting part 112 is provided corresponding to each temperature control element 120. In the embodiment shown in FIG9, there are two temperature control elements 120, spaced apart. In other embodiments, there may be only one temperature control element 120.

[0076] As shown in Figures 3 and 4, in one embodiment, the heat sink 130 includes a main body 131 and extensions 132. A liquid flow channel 133 is located in the main body 131. Each extension 132 corresponds to a temperature control element 120, and the extensions 132 extend from the main body 131 towards the temperature control element 120, allowing the heat from the temperature control element 120 to be conducted more quickly to the main body 131 where the liquid flow channel 133 is located. When there are multiple extensions 132, adjacent extensions 132 are spaced apart, so that the heat from each temperature control element 120 is transferred to the main body 131 through its corresponding extension 132, and then the liquid in the liquid flow channel 133 within the main body 131 exchanges heat with it, avoiding heat exchange between different extensions 132, preventing interference with the heat conduction path, and reducing heat conduction efficiency. In some embodiments, a heat insulation element may also be provided between adjacent extensions 132 and adjacent temperature control elements 120 to prevent thermal radiation interference from different temperatures of the temperature control elements 120 to adjacent temperature control elements 120.

[0077] As shown in Figures 3 and 4, in one embodiment, the metal bath assembly 100 includes a first heat insulation member 141. The first heat insulation member 141 is made of a material with heat insulation effect. For example, the first heat insulation member 141 can be a heat-insulating plastic component. The first heat insulation member 141 has a ring structure and encloses a placement space 1411 that is open at both the top and bottom. The heat-conducting part 112, the temperature control member 120, and the extension part 132 are all located within the placement space 1411 to prevent the heat dissipation of the temperature control member 120 from affecting the heating or cooling efficiency of the metal base 110.

[0078] As shown in Figures 3 and 4, in one embodiment, the metal bath assembly 100 further includes a water collection tray 150. In this embodiment, the water collection tray 150 is made of a material with low thermal conductivity, such as plastic. The water collection tray 150 is connected to the end face of the support portion 111 facing the temperature control element 120, and the water collection tray 150 has an annular structure surrounding the heat-conducting portion 112. The heat-conducting portion 112 and the water collection tray 150 are spaced apart. In this embodiment, since a first heat insulation element 141 is provided on the outer periphery of the heat-conducting portion 112, the water collection tray 150 and the first heat insulation element 141 are also spaced apart to further prevent heat dissipation from the temperature control element 120.

[0079] As shown in Figure 10, the water receiving tray 150 has a water receiving trough 151 that surrounds the support part 111 and is open at the top, for collecting condensate and overflowing or spilled experimental samples.

[0080] As shown in Figures 3, 4 and 10, in one embodiment, the water tray 150 has a guide surface 152 defining the bottom of the water tank 151. The guide surface 152 is inclined at a downward slope in the direction away from the metal base 110 so that condensate or sample liquid can flow along the guide surface 152 and collect, avoiding water accumulation.

[0081] In one embodiment, the end faces of the different walls of the water receiving tank 151 are all rounded to ensure that there are no hard-to-clean corners in the water receiving tank 151, thus eliminating dead corners and preventing dirt accumulation.

[0082] As shown in Figure 10, in one embodiment, the water receiving tray 150 is provided with a drain hole 153, which is connected to the water receiving trough 151 and located at the lowest point of the bottom of the water receiving trough 151, so as to facilitate the drainage of water in the water receiving trough 151.

[0083] As shown in Figure 8, in one embodiment, the metal bath device 10 further includes a drain pipe 600, which is connected to the drain hole 153 in each metal bath assembly 100 to collect water in each water tank 151 into the drain pipe 600 for drainage.

[0084] As shown in Figures 8 and 10, in one embodiment, a drain column 154 protrudes from the end face of the water receiving tray 150 away from the water receiving trough 151. The drain column 154 is aligned with the drain hole 153, and the drain hole 153 passes through the drain column 154. The drain column 154 passes through the hole opened in the mounting plate 170, so that the drain hole 153 is connected to the drain pipe 600 located below the mounting plate 170, so as to collect the water in the drain trough into the drain pipe 600.

[0085] As shown in Figures 5 and 9, in one embodiment, the metal base 110 further includes a first limiting ring 113. The first limiting ring 113 protrudes from the end face of the support portion 111 facing the temperature control element 120 and is located at the edge of the support portion 111, as shown in Figures 4 and 5. For ease of explanation, the first limiting ring 113 and the support portion 111 are separated by dashed lines in Figures 4 and 5, but this is only for illustrative purposes. In some embodiments, the first limiting ring 113 and the support portion 111 are an integral structure. As shown in Figures 5 and 10, a second limiting ring 155 protrudes from the end face of the water receiving tray 150 facing the support portion 111. The first limiting ring 113 and the second limiting ring 155 are staggered and at least partially overlap in the height direction. The staggered arrangement of the first limiting ring 113 and the second limiting ring 155 means that they are staggered in the radial direction of the water receiving tray 150. In this embodiment, the first limiting ring 113 is located on the outer periphery of the second limiting ring 155. In other embodiments, the second limiting ring 155 may also be located on the outer periphery of the first limiting ring 113, so that the first limiting ring 113 and the second limiting ring 155 can be engaged with each other, thereby fixing the position of the water receiving tray 150 and the metal base 110 and preventing the metal base 110 and the water receiving tray 150 from shifting.

[0086] As shown in Figures 3 and 5, in one embodiment, the metal bath assembly 100 further includes a sealing ring 160. The sealing ring 160 is sandwiched between the first limiting ring 113 and the second limiting ring 155, or between the first limiting ring 113, the second limiting ring 155, and the end face of the water receiving tray 150 facing the support portion 111, to seal the gap between the metal base 110 and the water receiving tray 150, preventing liquid in the water receiving tank 151 from flowing into the interior of the metal bath assembly 100 and interfering with the operation of the temperature control element 120, etc. In this embodiment, the sealing element is made of an elastic material so that it can adapt to thermal expansion and contraction.

[0087] As shown in Figures 5 and 9, in one embodiment, the first limiting ring 113 includes an abutment surface 1131 disposed facing the end face of the second limiting ring 155 and the water receiving tray 150 toward the support portion 111. The abutment surface 1131 is inclined at an upward slope in the direction close to the support portion 111, which can press the sealing ring 160 to obtain a better sealing effect, and can also reduce the contact area between the metal base 110 and the water receiving tray 150, thereby reducing heat transfer and heat dissipation.

[0088] As shown in Figures 3 and 4, in one embodiment, the metal bath assembly 100 further includes a mounting plate 170. As shown in Figure 11, the end face of the water receiving tray 150 facing away from the metal base 110 has multiple legs 156 protruding from it. The multiple legs 156 are fixedly connected to the mounting plate 170, which reduces the contact area between the water receiving tray 150 and the metal base 110, and also limits the installation position of the water receiving tray 150, achieving precise installation and ensuring the positional accuracy and rigidity of the contact surface of the experimental sample. As shown in Figure 3, the mounting plate 170 has a through hole 171 for the heat sink 130. The heat sink 130 passes through at least part of the through hole 171 to connect to the metal base 110 located above the mounting plate 170.

[0089] As shown in Figures 1 and 2, the mounting plates 170 of the different metal bath components 100 within the metal bath apparatus 10 are on the same plane. In this embodiment, the mounting plates 170 of each metal bath component 100 are connected as a single unit. In this embodiment, the metal bath apparatus 10 also includes a support frame 500 connected below the mounting plate 170. This support frame is fixedly connected to the mounting plate 170 and surrounds the metal bath component 100 to improve the strength of the mounting plate 170 and prevent deformation or breakage due to insufficient strength when using robotic arms and grippers to place and retrieve samples. Optionally, the support frame 500 is made of a chemically resistant metal material, such as 316 stainless steel or duplex stainless steel. In this embodiment, the mounting plate 170 may also be equipped with clips, positioning components, etc., to facilitate compatibility with automated pipetting workstations, laboratory benches, test stands, and other equipment platforms, allowing for quick and easy installation.

[0090] As shown in Figures 3 and 4, in one embodiment, the metal bath assembly 100 further includes a second heat insulation member 142. The second heat insulation member 142 is at least partially located between the heat sink 130 and the wall of the through hole 171 to prevent heat exchange between the heat sink 130 and the mounting plate 170 from affecting the heat exchange function of the heat sink 130 on the temperature control member 120. The second heat insulation member 142 is made of a material with heat insulation effect; exemplarily, the second heat insulation member 142 can be a heat-insulating plastic component.

[0091] As shown in Figures 3 and 4, in one embodiment, the metal bath assembly 100 further includes a third heat insulation member 143. The third heat insulation member 143 is located between the heat sink 130 and the wall of the through hole 171, and between the heat sink 130 and the drip tray 150, to prevent heat exchange between the heat sink 130 and the mounting plate 170, and between the heat sink 130 and the drip tray 150, which would affect the heat exchange function of the heat sink 130 on the temperature control member 120. The third heat insulation member 143 is made of a material with heat insulation effect; exemplarily, the third heat insulation member 143 can be a heat-insulating plastic component.

[0092] As shown in FIG9, in one embodiment, the metal bath assembly 100 further includes a first temperature detection element 182, wherein the first temperature detection element 182 is used to detect the temperature of the heat sink 130.

[0093] As shown in Figure 12, in one embodiment, the metal bath assembly 100 further includes a flow regulator 1821. The flow regulator 1821 is controlled by a temperature sensor and is used to control the flow rate of the liquid in the liquid flow channel 133 based on the temperature measured by the first temperature sensor 182. This allows for automatic regulation of the liquid flow rate in the liquid flow channel 133 by controlling the temperature of the heat sink 130. For example, when the temperature of the heat sink 130 differs significantly from the expected temperature, the liquid flow rate in the liquid flow channel 133 is increased to achieve faster temperature exchange efficiency. Conversely, when the temperature of the heat sink 130 is not significantly different from the expected temperature, the liquid flow rate can be reduced, thereby achieving energy savings.

[0094] In one embodiment, the flow regulator can be a circulating pump. The working principle of the flow regulator is as follows: the first temperature detection device transmits the detected temperature of the heat sink 130 to the external controller. The external controller controls the flow regulator to adjust the liquid flow rate in the liquid flow pipe 133 according to the temperature of the heat sink 130, thereby adjusting the heat dissipation rate of the heat sink 130.

[0095] As shown in Figure 12, in one embodiment, the metal bath assembly 100 further includes a pipe 1822 connecting an external liquid source and a liquid flow channel 133, and a heat dissipation assembly acting on the liquid within the pipe 1822. The heat dissipation assembly is controlled by a first temperature sensor 182 and is used to control the temperature of the liquid within the pipe 1822 based on the temperature measured by the first temperature sensor 182. Exemplarily, the external liquid source is connected to the liquid flow channel 133 through the pipe, forming a circulating liquid flow loop. The heat dissipation assembly acts on the liquid within the pipe, thereby controlling the temperature of the liquid within the liquid flow channel 133. This increases the temperature difference between the liquid and the heat dissipation assembly 130 by adjusting the temperature of the liquid within the liquid flow channel 133, thereby improving heat exchange efficiency. Exemplarily, the heat dissipation assembly can be a cooling fan, heat dissipation fins, etc.

[0096] As shown in Figure 9, in one embodiment, the metal bath assembly 100 further includes a second temperature sensing element 183 thermally connected to the metal base 110. The second temperature sensing element 183 is used to detect the temperature of the metal base 110. By detecting the temperature of the metal base 110 through the second temperature sensing element 183, it can be confirmed whether the metal base 110 has been heated or cooled to the required temperature, thereby inferring the working effect of the temperature control element 120 and providing a basis for further adjustment of the temperature control element 120, so as to achieve accurate adjustment of the target temperature of the metal base 110.

[0097] It is understood that there can be multiple second temperature sensors 183. When there are multiple second temperature sensors 183, they can be distributed at different positions on the metal base 110 to confirm the temperature at each position on the metal base 110. In the embodiment shown in FIG9, there is one second temperature sensor 183, which is located at the planar geometric center of the metal base 110. When there are multiple second temperature sensors 183, they are preferably symmetrically arranged at various locations on the metal base 110.

[0098] As shown in Figure 9, in one embodiment, the metal base 110 is recessed with at least one groove 114, and a second temperature sensing element 183 is correspondingly disposed in each groove 114, with each second temperature sensing element 183 at least partially located within the corresponding groove 114. In the embodiment shown in Figure 9, only one groove 114 is illustrated in the metal base 110, but in other embodiments, the number of grooves 114 may be greater, depending on the number of second temperature sensing elements 183.

[0099] As shown in Figures 3 and 4, in one embodiment, the metal bath assembly 100 further includes a control board 181, which is electrically connected to the temperature control element 120. The control board 181 is located on the end face of the heat sink 130 opposite to the temperature control element 120, and a filler material 190 is sandwiched between the control board 181 and the heat sink 130. The filler material 190 is a thermally conductive material to facilitate heat exchange between the control board 181 and the heat sink 130, thereby dissipating heat from the control board 181 through the heat sink. In this embodiment, the filler material 190 is a thermally conductive silicone pad, but this is not a limitation. As shown in Figure 4, in this embodiment, the second heat insulation element 142 is partially sandwiched between the control board 180 and the heat sink 130. Optionally, fasteners securely press the control board 181, the second heat insulation element 142, and the heat sink 130 together, and a heat insulation pad is provided between the fasteners and the heat sink 130.

[0100] As shown in Figure 8, in one embodiment, each metal bath assembly 100 is provided with a control board 181. Therefore, the temperature control element 120 in each metal bath assembly 100 is independently controlled, and the temperature control element 120 in different metal bath assemblies 100 can be set to different temperatures.

[0101] As shown in Figures 1 and 2, in one embodiment, the metal bath device 10 further includes a liquid detection element 400 and a chassis cover 300 located at the bottom of the metal bath assembly 100. The liquid detection element 400 is used to detect the presence of liquid. The chassis cover 300 has a collection cavity 310 with an open top. Each metal bath assembly 100 is located within the projection of the chassis cover 300 on the mounting plate 170. Each metal bath assembly 100 is at least partially located within the collection cavity 310 so that the chassis cover 300 can cover each metal bath assembly 100. When any metal bath assembly 100 leaks liquid, it can be collected in the collection cavity 310. The liquid detection element 400 is disposed within the collection cavity 310 and located at the lowest point of the collection cavity 310 so that when any metal bath assembly 100 leaks liquid, the liquid detection element 400 can detect it in time and issue an alarm. When liquid is detected, the metal bath device 10 will automatically stop working to ensure safe use.

[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
