[0002] In a vibrating metal bath device, the refrigeration module is the core component for achieving low-temperature constant temperature control of the sample. Its structural design directly affects the equipment's refrigeration efficiency, ease of assembly, and maintenance costs.

[0003] In the existing technology, the following specific problems exist with refrigeration-related structures:

[0004] The refrigeration components, drive circuits, temperature sensing components, etc. required for refrigeration are mostly independent and scattered parts, which need to be fixedly connected to the main body of the equipment. During assembly, the position of each component needs to be adjusted one by one to ensure circuit conductivity and refrigeration effect. This not only takes a long time, but also easily leads to a decrease in refrigeration efficiency or poor circuit contact due to assembly errors. Utility Model Content

[0006] The objective of this utility model can be achieved through the following technical solution: A cooling module for an oscillating metal bath includes a module base, a module plastic cover, a circuit board, a cooling component, a sensing component, and a limiting support structure. The module base and the module plastic cover cooperate to form a placement cavity. The circuit board, the cooling component, and the sensing component are all disposed in the placement cavity. The cooling component is electrically connected to the circuit board. The sensing component is used to realize the module sensing function.

[0025] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below. Example 1

[0026] A cooling module for an oscillating metal bath includes a module base 1, a module plastic cover 2, a circuit board 3, a cooling component 4, a sensing component 5, and a limiting support structure 6. The module base 1 and the module plastic cover 2 cooperate to form a placement cavity. The circuit board 3, the cooling component 4, and the sensing component 5 are all disposed within the placement cavity. The cooling component 4 is electrically connected to the circuit board 3. The sensing component 5 is used to realize the module's sensing function. The limiting support structure 6 provides limiting support for the components in the placement cavity.

[0027] like Figures 1-4 As shown, the module base 1 of this utility model serves as the basic load-bearing structure. Its edge cooperates with the module plastic cover 2 to form a placement cavity. The circuit board 3 is fixed to the module base 1 inside the placement cavity by screws. The cooling component 4 is welded to the surface of the circuit board 3 and electrically connected to the circuit board 3 to realize the cooling function. The sensing component 5 is set on one side of the circuit board 3 to sense different modules. The limiting support structure 6 consists of columns distributed at the four corners of the cooling component 4. Its top end abuts against the lower end of the module base 1 to provide limiting support for the circuit board 3, cooling component 4 and sensing component 5 inside the placement cavity, preventing the components from shifting during vibration. At the same time, it provides rigid support to prevent the cooling component 4 from being crushed during installation.

[0028] The modular integrated design of this utility model integrates all components into one unit through the placement cavity, which facilitates quick assembly and individual replacement; the limiting support structure 6 ensures the stability of internal components under vibration environment.

[0029] As a further preferred embodiment, the cooling component 4 includes at least one set of cooling chips 41, which are soldered to the circuit board 3 and have insulation cotton 42 on their outer side. A heat sink 7 is provided on the side of the cooling chip 41 away from the circuit board 3.

[0030] Specifically, the cooling chip 41 is fixed to the surface of the circuit board 3 by soldering, forming an electrical connection with the conductive lines of the circuit board 3 to achieve the cooling effect driven by electric energy. The outside of the cooling chip 41 is wrapped with heat insulation cotton 42, which completely covers the side of the cooling chip 41 to reduce the loss of cold energy to the surrounding environment. The side of the cooling chip 41 away from the circuit board 3 is tightly attached to the heat sink 7. The heat sink 7 is in contact with the cooling chip 41 through thermally conductive silicone to quickly conduct the heat generated by the cooling chip 41 when it is working, so as to avoid heat accumulation and affect the cooling efficiency.

[0031] As a further preferred embodiment, the circuit board 3 is a cooling chip circuit board and its lower end is provided with a terminal block 31. External lines are connected to the cooling chip circuit board through the terminal block 31 to realize power supply and signal transmission.

[0032] Specifically, the external line connector can be directly plugged into the terminal block 31 to enable the external power supply to the cooling chip circuit board, and at the same time complete the signal transmission between the cooling module and the external control system. The plug-in connection structure facilitates quick disassembly and replacement of the module. When the cooling module needs maintenance or replacement, it can be separated simply by unplugging the external line connector, which significantly improves the ease of operation and further reduces maintenance costs.

[0033] As a further preferred embodiment, the sensing component 5 includes a Hall effect sensing circuit board 51 and a temperature probe 52, wherein the Hall effect sensing circuit board 51 and the temperature probe 52 are disposed on the side of the cooling component 4.

[0034] As a further preferred embodiment, the limiting support structure 6 consists of four height-limiting columns, which are distributed at the four corners of the cooling component 4.

[0035] Specifically, the top of the limiting support structure 6 abuts against the inner wall of the module plastic cover 2, forming a rigid support for the cooling component 4 from all sides, preventing internal components from shifting or colliding due to shaking during the vibration process.

[0036] As a further preferred embodiment, the lower end of the heat sink 7 is provided with a groove 71, and a polarization mechanism 8 is provided in the groove 71. The polarization mechanism 8 includes a bearing chamber 81 fixedly disposed in the groove 71 and an eccentric block 82 rotatably disposed in the bearing chamber 81.

[0037] Specifically, the dimensions of the groove 71 are adapted to the polarization mechanism 8; the polarization mechanism 8 is installed in the groove 71, wherein the bearing chamber 81 is fixed to the inner wall of the groove 71 by screws, and its axis coincides with the central axis of the heat sink 7. The eccentric block 82 is a fan-shaped block structure, and its central axis is interference-fitted with the inner ring of the bearing in the bearing chamber 81, allowing the bearing chamber 81 to rotate freely, and the center of gravity of the eccentric block 82 is offset from its rotation axis.

[0038] When the external drive structure drives the eccentric block 82 to rotate, the eccentric design of the eccentric block 82 generates periodic centrifugal force, which is transmitted to the entire cooling module through the bearing chamber 81 and the heat sink 7 to realize the oscillation function of the module. The setting of the groove 71 makes the polarization mechanism 8 and the heat sink 7 form a compact integrated structure, reducing the overall space occupied by the module. At the same time, the rigid structure of the heat sink 7 provides stable support for the polarization mechanism 8, preventing loosening during the oscillation process.

[0039] As a further preferred embodiment, the module base 1 is provided with multiple sets of mounting holes 11.

[0040] Specifically, the design of multiple sets of mounting holes 11 allows the cooling module to be adapted to experimental containers of different sizes and types, improving its versatility.

[0041] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
