With the development of science and technology, the market demand for such equipment is also increasing, not only do they need to respond quickly to temperature changes, but also require them to have high efficiency, high precision and environmental protection.

[0003] At present, the cold and heat regulating equipment on the market is mainly divided into single refrigeration system and single heating system. Although these devices play an important role in a specific field, their design and function have obvious limitations. First, the single function limits the application range of the equipment, users often need to purchase multiple devices according to different temperature requirements, which increases the cost and operation complexity. Second, the existing temperature control system has insufficient precision, which makes it difficult to achieve accurate temperature regulation, resulting in poor user experience. In addition, energy consumption is also a problem that cannot be ignored, independent refrigeration and heating modules lead to energy waste, especially when frequently switching between working states.

[0066] Optionally, the heat exchange pipeline system further comprises a display provided on the bathtub shell (71), and the display is controlled by the controller and used to display the operation mode and the operation temperature of the heat exchange pipeline system.

[0067] The ice bath refrigeration bathtub of the application successfully solves a plurality of problems of the prior art and brings significant beneficial effects. First, the bathtub 7 integrates a heat exchange pipeline system, including an air compressor 1, a four-way valve 3, a condenser 4, an expansion mechanism 5 and an evaporator 6, and these components are communicated through a refrigerant pipe 2, which can realize accurate heating or cooling of the liquid in the bathtub 7. Such design breaks through the limitation of single refrigeration or heating, provides bidirectional temperature adjustment capability, and greatly expands the application range of the equipment.

[0068] In terms of temperature control accuracy, the application of intelligent controllers improves the response speed and adjustment accuracy of the system, ensuring the stability and uniformity of the liquid temperature in the bathtub 7. This is particularly important for chemical and biological laboratory applications that require precise temperature control, and is a direct response to the lack of temperature control accuracy in existing technology.

[0069] In terms of energy consumption, by optimizing the operation of the cooling system and the heating system, the device of the present application can reduce energy waste, especially when frequently switching between heating and refrigeration states, improving the efficient use of energy. This conforms to the concept of green building, emphasizes the efficient use of energy, and is consistent with the trend of the combined application of environmentally friendly refrigerants and green refrigeration technology, helping to reduce the adverse effects on the environment.

In addition, the present application takes into account environmental protection, uses environmentally friendly refrigerants, reduces damage to the atmosphere, and conforms to the development trend of environmental protection and green refrigeration technology.

[0071] Finally, the improvement of ice generation and ice removal functions enables the device to accurately control water temperature and ice shape, meeting the needs of specific application scenarios such as ice generation and management on water surfaces. This precise temperature and ice control capability provides users with more convenience and flexibility.

[0072] The ice bath refrigeration bathtub of the present application integrates innovative temperature control technology, not only improving the functionality and operational convenience of the device, but also optimizing energy consumption and reducing environmental pollution, meeting the needs of modern industry and life for efficient, environmentally friendly, and precise temperature control.

[0073] In one embodiment, an ice bath refrigeration bathtub is provided, with S-shaped copper pipes winding back and forth around the four sides and the bottom of the bathtub liner 72, using a flattened method;

[0074] The design principle of the S-shaped copper pipe is that the S-shaped copper pipe is a common means to improve heat exchange efficiency. By designing the pipe into an S shape, the refrigerant flowing in the pipe will experience multiple curved turning points, which can increase the contact time between the refrigerant and the pipe wall, thereby improving the efficiency of heat exchange. Specifically, the S-shaped copper pipe plays the following roles:

[0075] Increase contact area: The curved structure of the S-shaped pipe greatly increases the contact area between the copper pipe and the bathtub liner 72. Compared with a simple straight pipe, the curved copper pipe has more surface area per unit length, which can more effectively conduct heat from the bathtub liner 72 to the refrigerant.

[0076] Extended Flow Path: The S-shaped layout extends the flow path of the cooling liquid, allowing the refrigerant to flow within the pipe for a longer period of time, increasing the heat exchange time with the copper pipe, thus enhancing the overall refrigeration effect.

[0077] Flattened Copper Pipe Design: The flattened design of the copper pipe is another key factor that further enhances heat exchange efficiency by altering the cross-sectional shape of the pipe. Compared to a round copper pipe, the flattened copper pipe has several advantages:

[0078] Increased Surface Area: The surface area of the flattened copper pipe is larger than that of the original round pipe, allowing more coolant to come into contact with the copper pipe surface, thereby enhancing the efficiency of heat exchange.

[0079] Optimized Contact Angle: The flattened copper pipe surface is more easily in contact with the bathtub inner liner 72, making heat transfer more uniform and efficient. This design further enhances the efficiency of heat exchange between the cooling liquid and the heat source.

[0080] Improved Cooling Effect: The flattened copper pipe can better adapt to the shape of the bathtub inner liner 72, especially the curved surfaces of the bottom and sides, allowing it to closely adhere to the inner liner surface, quickly removing heat and optimizing overall cooling efficiency.

[0081] Five-Surface Contact Overall Structure: In the cooling system design, the cooling efficiency of the bathtub inner liner 72 depends on the surface area of heat exchange and the flow path of the cooling liquid. Arranging the five surfaces with the S-shaped flattened copper pipe structure has the following advantages:

[0082] All-Around Cooling: The bathtub 7 is not only cooled at the bottom, but also at the sides, front and back, ensuring that heat is effectively removed from each area and that the cooling effect is not uneven due to excessive heat in a local area.

[0083] Improved Overall Performance: Due to the greatly increased area covered by the copper pipe, the heat exchange efficiency of the entire cooling system is improved, especially in cases where the bathtub 7 is large and cooling demand is high, providing more stable cooling effects.

[0084] Specific Process of Heat Exchange: In this design, the process of heat exchange is achieved through the flow of refrigerant within the copper pipe. The coolant flows through the flattened S-shaped copper pipe, absorbing and removing the heat from the bathtub inner liner 72. The specific process is as follows:

[0085] Heat Absorption Stage: The heat in the bathtub 7 is transferred to the coolant through the contact surface of the copper pipe. When the temperature on the surface of the copper pipe is low, the heat is transferred from the bathtub inner liner 72 to the coolant through the copper pipe.

[0086] Heat exchange enhancement: Due to the larger contact area of the flattened copper tubes, the heat exchange efficiency of the refrigerant is higher than that of round copper tubes. The refrigerant flows through the S-shaped curved pipes, extending the heat exchange time and further enhancing heat transfer.

[0087] Heat dissipation phase: The cooling liquid circulates through the compressor, absorbing the heat and releasing it to the external environment, gradually reducing the temperature of the bathtub inner shell 72.

[0088] Overall benefits of the structure: Overall, this S-shaped flattened copper tube design significantly improves the cooling effect of the bathtub 7, mainly in the following aspects:

[0089] Efficient cooling: Due to the increased surface area and prolonged contact time, the cooling liquid can quickly absorb the heat of the bathtub inner shell 72 and carry it away.

[0090] Uniform cooling: The five faces are evenly arranged with cooling copper tubes, ensuring that each area is effectively cooled and avoiding excessive temperature differences.

[0091] Energy-efficient: Due to the increased heat exchange efficiency, this design can quickly reach the required temperature, reducing energy consumption and improving the overall energy efficiency of the device.

[0092] The purpose of this structure and design optimization is to improve cooling efficiency and reduce energy consumption through more efficient heat exchange, thereby improving device performance and user experience.

[0093] As shown in Figure 9 and Figure 10 , the heat dissipation fan orientation changes from inside to outside; the design principle of the heat dissipation fan orientation from inside to outside: Generally, the design of the heat dissipation fan needs to consider the direction of air flow and efficiency. The design of the fan facing from inside to outside, i.e. the fan extracts hot air from the inside of the device and discharges it to the outside, has the following key advantages compared to the outward blowing method:

[0094] Optimize hot air discharge: The interior of the device usually accumulates a large amount of heat when working, especially for high-power devices such as electronic components or refrigeration systems. When the fan faces from inside to outside, it can directly discharge these high-temperature gases to the external environment, thereby avoiding the retention of hot air in the device interior, causing the internal temperature to be too high.

[0095] Improve cooling efficiency: Through the inward-outward fan design, air can flow through the key heat source areas of the device (such as the cooling system or electronic components), carrying away heat, thereby improving the overall heat dissipation effect. This helps the device maintain a stable working temperature, reducing performance degradation or damage caused by overheating.

[0096] Lowering internal temperature: Temperature control inside the device is one of the key factors that affect its efficiency and lifespan. The inward-outward fan design can effectively lower the internal temperature of the device, ensuring its stable operation.

[0097] The impact of ambient temperature on the cooling effect of the device, the ambient temperature largely determines the cooling effect of the device. The role of the cooling fan is to carry away heat through air flow, and the temperature of the air determines the efficiency of cooling. The specific impact can be analyzed from the following aspects:

[0098] a) When the ambient temperature is high

[0099] Reduced cooling efficiency: When the ambient temperature is high, the temperature of the air itself is already high, which means that when the cooling fan expels hot air from the device, it cannot effectively carry away heat. Therefore, in a high-temperature environment, the cooling efficiency of the device will be affected, and the device may experience overheating or excessively high temperature.

[0100] Increased active cooling demand: In a high-temperature environment, additional cooling measures may be needed to ensure the normal operation of the device. For example, increasing the power of the fan or using advanced cooling technologies such as liquid cooling systems, heat pipes, etc. to improve cooling efficiency.

[0101] b) When the ambient temperature is low

[0102] Good cooling effect: When the external environment is cool, the cooling fan can more efficiently expel the heat inside the device, greatly improving the cooling effect of the device. This is very beneficial for the long-term stable operation of the device, especially for precision equipment or high-load running systems.

[0103] Energy-saving effect: In a low-temperature environment, the cooling efficiency of the device is improved, which can reduce the energy consumption required for the fan to work, reducing overall energy consumption.

[0104] c) The impact of temperature difference on the device

[0105] Impact when temperature difference is too large: When the temperature difference between the inside of the device and the external environment is too large, the cooling efficiency of the device may be affected. For example, in winter, the external environment temperature is low and the internal temperature of the device is high. Although the fan can effectively carry away heat, due to the overcooling of external air, it may cause a large temperature difference between the inside and outside of the device, leading to condensation or other device failures.

[0106] Impact of high-temperature environment on device lifespan: If the device works in a high-temperature environment for a long time, it may cause overheating of internal electronic components or cooling systems, affecting the service life and stability of the device. High-temperature environments can also accelerate the aging of components, shortening the effective use time of the device.

[0107] The environmental temperature and the fan design can be combined to overcome the impact of environmental temperature on equipment heat dissipation. Some comprehensive design and technical measures can be taken:

[0108] Increase the temperature control system: Combine with intelligent temperature control system, automatically adjust the speed and working state of the fan. For example, when the environmental temperature is high, automatically increase the speed of the fan to increase air flow; in low temperature environment, reduce the speed of the fan to avoid the influence of overcooling air.

[0109] Select the appropriate fan type: According to the environmental conditions, select different types of cooling fans. For example, in high temperature environment, you can choose high temperature resistant fan or fan with stronger cooling capacity.

[0110] External cooling auxiliary equipment: For extreme high temperature environment, external cooling auxiliary equipment such as air cooler or liquid cooling system may be needed to further improve the heat dissipation efficiency of the equipment.

[0111] As shown in Figure 11 , the transformer 10 is moved from inside the electrical box to outside the electrical box. The transformer 10 works by electromagnetic induction principle, which converts electrical energy from one voltage level to another. In this process, the copper wire and iron core of the transformer 10 will generate heat due to the flow of current. Especially in the case of high load or long time operation, the heat generated by the transformer 10 will continue to accumulate, and if the heat dissipation is insufficient, it may cause overheating, which will affect the working efficiency, service life of the transformer 10 and even cause failure. Therefore, effective heat dissipation design is crucial for the normal operation of the transformer 10.

[0112] The advantages of moving the transformer 10 from inside the electrical box to outside the electrical box:

[0113] a) Improve heat dissipation efficiency

[0114] Avoid heat accumulation: The space inside the electrical box is usually limited, and the internal electrical components are relatively dense. When the transformer 10 is placed inside the electrical box, the heat generated is easy to accumulate inside the electrical box, causing the temperature inside the electrical box to rise. If the transformer 10 is moved to the outside of the electrical box, the heat can be more easily dissipated to the outside environment, thereby improving the heat dissipation efficiency.

[0115] Improve air flow: In the outside of the electrical box, the air flow is usually more smooth, and the heat is not easy to be trapped around the equipment. By placing the transformer 10 outside, you can use natural convection or fan assisted cooling methods to quickly remove hot air, further improving the cooling effect.

[0116] b) Reduce the temperature rise inside the electrical box

[0117] Reducing the load on the electrical box: When the transformer 10 is located inside the electrical box, it can affect the operating temperature of other components within the box, increasing the thermal load on internal components. Especially when multiple electronic components or switching devices are placed in the same electrical box, excessive internal temperature can affect the stability and lifespan of these devices. By moving the transformer 10 outside the electrical box, the temperature burden on the inside of the electrical box can be reduced, avoiding device failure due to overheating.

[0118] c) Extending the lifespan of the transformer 10 and other components

[0119] Preventing overheating damage: The transformer 10 is in a high-temperature environment for a long time, which can accelerate the aging of the insulation material inside the coil and shorten its service life. Moving the transformer 10 outside can reduce the damage of such overheating to the transformer 10, improve its reliability and service life. At the same time, other electronic components inside the electrical box can also work at a lower temperature, extending their service life.

[0120] d) Enhancing the convenience of maintenance and monitoring

[0121] Convenient inspection and maintenance: Placing the transformer 10 outside the electrical box makes it easier for maintenance personnel to access the transformer 10, facilitating temperature monitoring, inspection, and cleaning, and other maintenance work. Compared to hiding the transformer 10 inside the electrical box, the external location can significantly improve the convenience and efficiency of maintenance.

[0122] Constant temperature mode

[0123] 1. Working principle of constant temperature mode

[0124] The basic idea of constant temperature mode is to keep the temperature of the environment or object where the device is located within a predetermined range without large fluctuations. This is usually done by monitoring the difference between the current temperature and the target temperature, and then controlling the start and stop of the device.

[0125] a) Temperature setting and control

[0126] Set temperature: The user of the device can set a target temperature (such as 5℃), and the device will adjust the temperature according to this set value.

[0127] Temperature fluctuation range: Constant temperature mode usually sets a range of allowed temperature fluctuations, which is the basis for the start and stop of the device. In your design, when the temperature is 3℃ higher than the set value, the device will automatically start, ensuring that the environment temperature does not exceed the set value range.

[0128] b) Temperature monitoring and feedback control

[0129] The device needs to continuously monitor the current temperature and compare it with the set temperature. If the temperature exceeds the pre-set range, the control system will send a start signal. For example, if the set temperature is 5°C and the device's "over-temperature start threshold" is set to 3°C, the device will automatically start when the temperature reaches or exceeds 8°C.

[0130] 2. Key factors in design

[0131] a) Temperature hysteresis

[0132] Temperature hysteresis refers to the temperature difference at which the device starts or stops in a thermostat system. By setting a hysteresis of 3°C, it can effectively avoid frequent start / stop and prevent the device from overworking due to small temperature fluctuations. In simple terms, the device starts when the temperature reaches the set temperature + 3°C. This design can reduce the frequency of device start / stop, prolong the service life of the device, and reduce energy consumption.

[0133] b) Precision and response speed of control system

[0134] In order to ensure that the device can start or stop at the right time, the control system needs to have high temperature measurement accuracy and fast response speed to prevent rapid temperature fluctuations.

[0135] c) Energy-saving considerations

[0136] When the device starts only when the temperature is 3°C higher than the set value, it helps to reduce unnecessary working time of the device. This can avoid the device running frequently when the temperature is close to the set value, reducing energy waste.

[0137] 3. Energy-efficient implementation mechanism

[0138] The energy-saving advantages of this design mainly include the following aspects:

[0139] a) Reduce start / stop frequency

[0140] By setting the temperature hysteresis (e.g. 3°C), it can avoid frequent start / stop of the device, reduce the consumption of starting current, and improve the overall efficiency of the system. The device will not start constantly due to small changes in environmental temperature, which can effectively reduce energy consumption.

[0141] b) Reduce invalid running time

[0142] If the device runs continuously, even if the temperature does not change much, it will also cause unnecessary energy consumption. By allowing the device to start only when the temperature exceeds 3°C, it ensures that the device only works when it is really needed, avoiding unnecessary energy waste.

[0143] c) Improve the working efficiency of the device

[0144] When the device is running, the temperature control system adjusts according to the difference between the set value and the actual temperature, and the device runs in the best working state. Through reasonable temperature control and effective start-stop mechanism, the working efficiency of the device is optimized, further saving energy.

[0145] d) Stability of temperature

[0146] The reduction of temperature fluctuations not only helps to save energy, but also ensures that the device works in a stable environment temperature. For refrigeration, heating or other temperature control devices, stable working temperature means higher efficiency and longer service life.

[0147] Working principle of double cooling fan 8:

[0148] The basic working principle of double cooling fan 8 is to increase the cooling efficiency by working simultaneously or alternately. Two fans can run simultaneously, respectively responsible for air flow in different directions, or work alternately, automatically adjusting the working state of the fan according to the temperature of the device.

[0149] In this mode, two fans work simultaneously to provide greater air flow. This can optimize cooling in the following ways:

[0150] Enhance air flow: Two fans together increase air flow, speed up heat removal, and improve cooling effect. Especially for high-power devices or scenes that require strong cooling, parallel fans can effectively enhance cooling capacity.

[0151] Share the load: Two fans work together to reduce the burden on a single fan, avoiding premature damage due to overloading of the fan.

[0152] As shown in Figure 12 the advantages of double cooling fan 8 design:

[0153] The simultaneous work of two fans can effectively increase the air flow, quickly remove heat, and thus improve the cooling capacity of the device, ensuring that the device can still run stably under high load.

[0154] Faster heat removal: Compared with single fan design, double fan system has stronger cooling capacity, which can remove a large amount of hot air in a short time and reduce the temperature inside the device.

[0155] Improve heat exchange efficiency: Two fans can effectively cool different parts, enhancing the overall heat exchange efficiency of the device.

[0156] b) Reduce fan load and prolong service life

[0157] Two fans working, compared to a single fan long time load operation, two fans can share the workload, reduce the load of each fan, thereby prolonging the service life of the fan.

[0158] Avoid overheating and damage: Overwork of the fan may cause the motor to overheat or be damaged, and the double-fan system can effectively reduce this risk and ensure long-term efficient operation of the fan.

[0159] c) Reduce noise

[0160] If designed properly, double-radiator fan 8 can reduce noise by evenly distributing airflow and reducing the operating frequency and burden of individual fans. Especially when using variable frequency fans, the system can adjust fan speed as needed to maintain the lowest noise level.

[0161] d) Better temperature control management

[0162] In scenarios requiring precise temperature control, double-radiator fan 8 can provide more stable air circulation and heat dissipation. Through intelligent control systems, the working state of the fan can be adjusted according to real-time temperature changes, allowing the device to operate within the optimal temperature range.

[0163] De-icing principle and four-way valve 3 switching:

[0164] a) Role of four-way valve 3

[0165] Four-way valve 3 is a reversing valve commonly used in refrigeration systems, which mainly controls the working state of the system by changing the flow direction of the refrigerant. During de-icing, the switching of four-way valve 3 plays a key role. By changing the flow direction of the refrigerant, the system can be switched from cooling mode to heating mode, providing a heat source for copper pipe heating.

[0166] Normal cooling mode: During the cooling process, four-way valve 3 causes the refrigerant to flow to the evaporator 6, absorbing heat inside the device to keep it cool.

[0167] De-icing mode: When entering de-icing mode, four-way valve 3 switches to change the flow direction of the refrigerant, causing the refrigerant to pass through the heating pipe to transfer heat, thereby increasing the temperature of the copper pipe and quickly melting the ice layer attached to the surface of the copper pipe and around the device.

[0168] b) Copper pipe heating process

[0169] Copper pipes generally have good thermal conductivity and are used as evaporators 6 or heat exchangers in refrigeration systems. When four-way valve 3 switches, the refrigeration system begins to heat the copper pipe and transfers heat to the ice layer through the heated copper pipe, thereby quickly melting the ice attached to the condenser 4, evaporator 6, and the surface of the device such as the bottom and the surrounding area.

[0170] Heating time: The copper pipe is usually heated for 15 minutes, which is enough to ensure that the ice blocks are evenly removed and no excessive ice layer is left in some areas.

[0171] Heat transfer: Due to the excellent thermal conductivity of copper, heat can be quickly transferred from the heating area to the ice layer, causing the ice layer to melt quickly.

[0172] By switching the four-way valve 3 and using the copper pipe heating method, the ice layer can be quickly melted in a short time. Compared with traditional manual ice scraping or natural melting, the system is more efficient by heating the copper pipe, which can save a lot of time and effort.

[0173] Fast ice removal: Generally only 15 minutes, can quickly restore the device to work, reduce downtime.

[0174] Uniform ice removal: The heating performance of the copper pipe causes the ice blocks to melt evenly, leaving no excessive ice blocks or moisture in some areas.

[0175] Traditional manual ice removal usually requires the user to use metal tools such as scrapers, shovels, etc. to scrape off the ice layer, which not only may damage the equipment, but also easily causes the user to be injured. Through the automatic ice removal function, the user does not need to personally contact the ice layer, thereby avoiding possible injuries.

[0176] Reduce the risk of operation: The system automatically removes the ice to avoid the risk of scratching the surface of the equipment and scalding the user.

[0177] Avoid equipment damage: Traditional manual ice removal may cause tools such as scrapers to contact the equipment, damaging the copper pipe or evaporator 6. While automated ice removal can accurately control the heating process, avoiding this problem.
