Description

Technical Field

[0001] The present application relates to the technical field of cold and hot air converters, and in particular to a cold and hot air converter. Background Art

[0002] In industrial production and daily life, the demand for hot and cold air is very common, and accurate control of air temperature is crucial. However, existing hot and cold air conversion equipment has many problems.

[0003] In terms of temperature control accuracy, traditional hot and cold air converters are difficult to achieve high-precision temperature regulation. Their temperature control systems often respond slowly and cannot quickly and effectively respond to changes in ambient temperature or set temperature adjustments. For example, in the manufacturing process of electronic chips, the temperature requirements for the welding process are extremely high, and a slight deviation may cause the chip performance to deteriorate or even be scrapped. However, existing converters are difficult to stabilize the hot air temperature within a very small error range, resulting in a high rate of defective products.

[0004] Energy consumption is also a prominent issue. Many traditional devices consume a lot of energy to maintain temperature regulation when switching between hot and cold air. Taking large industrial drying equipment as an example, in order to achieve the appropriate drying temperature, it is often necessary to continuously operate the heating or cooling device at high power, which not only causes a huge waste of energy, but also increases production costs. Moreover, during the temperature regulation process, due to the lack of an effective heat recovery and reuse mechanism, a large amount of heat or cold energy is directly discharged into the environment, further exacerbating energy loss.

[0005] In terms of structural design, the existing hot and cold air converters are relatively complex and bulky. This not only takes up a lot of installation space, but is also extremely inconvenient to install and use for some application scenarios with limited space, such as small household drying equipment and vehicle air conditioning auxiliary heating and cooling systems. At the same time, the complex structure also increases the manufacturing cost and maintenance difficulty of the equipment. Once a failure occurs, the repair time is long and the cost is high. Summary of the invention

[0006] In order to solve the problems of low temperature control accuracy, high energy consumption and compact structure of hot and cold air conversion equipment in the prior art, the present application provides a hot and cold air converter.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-6 This application is described in further detail.

[0028] The present application embodiment discloses a cold and hot air converter. Figure 1-6 A hot and cold air converter is mainly composed of an end shell 1, a connecting shell 2, a distribution component 3, a three-way valve 4, a temperature sensing probe 5, a heat exchange component 6 and a connecting component 7. The components work closely together to achieve efficient hot and cold air conversion and precise temperature control to meet the application requirements of different scenarios.

[0029] Reference Figure 1 , the end shell 1 and the connecting shell 2 are the basic frame structure of the entire hot and cold air converter. The end shell 1 and the connecting shell 2 are made of high-quality aluminum alloy materials and are formed by precision die-casting. The outer surface is provided with an insulation layer to prevent heat dissipation. After die-casting, the surface is finely processed to ensure the flatness and finish of each mounting surface, and the tolerance is controlled within ±0.05mm. Such high-precision surface treatment provides a reliable guarantee for the close fit of subsequent components. The two adjacent end shells 1 are connected by the connecting shell 2. The two ends of the connecting shell 2 and the end of the end shell 1 close to the connecting shell 2 are respectively provided with quick connectors A701 and quick connectors B702, which constitute a connecting component 7. The quick connectors A701 and B702 are made of stainless steel and the surface is chrome-plated to improve their corrosion resistance and connection reliability. The end shell 1 and the connecting shell 2 are connected together by flanges, and the connection is tight and leak-free, ensuring the stable flow of the heat carrier and the heat exchange fluid inside the equipment, and providing a structural basis for the smooth progress of the heat exchange process.

[0030] Reference Figure 6, a heat exchange assembly 6 is provided on the inner side of the end shell 1 and the connecting shell 2. The heat exchange unit 601 in the heat exchange assembly 6 is the core component for realizing heat exchange. The conducting pipe 6011 of the heat exchange unit 601 is made of a copper alloy pipe with high thermal conductivity and is made through precision drawing and machining. The copper alloy with high thermal conductivity can quickly transfer heat and improve the heat exchange efficiency. A twisted band 6013 is provided on the inner side of the conducting pipe 6011. The twisted band 6013 is made of stainless steel and is assembled with the conducting pipe 6011 through stamping and welding processes. The twisted band 6013 separates the conducting pipe 6011 into two independent and mutually entangled flow channels. This unique structural design increases the disturbance of the fluid in the pipe, enhances the heat transfer effect, and enables a more sufficient heat exchange between the heat carrier and the heat exchange fluid. Both ends of the twisted band 6013 are provided with sealing pieces 6014, and the sealing pieces 6014 are located in the flow channel on the side where the two guide holes 6012 are connected, and are used to isolate the flow channel here, further optimizing the flow path of the fluid and ensuring the high efficiency and stability of heat exchange.

[0031] Reference Figure 2 and Figure 4 , support plates 602 are provided at both ends of the heat exchange unit 601. The support plates 602 and the heat conducting plates 603 constitute a heat carrier flow cavity, and the heat conducting plates 603 and the heat conducting plates 603 and the end shell 1 constitute a heat exchange fluid flow cavity. The support plates 602 and the heat conducting plates 603 are made of pure copper and have excellent thermal conductivity. After mechanical processing and surface treatment, they are assembled with the conducting pipe 6011 to ensure the sealing of the heat carrier flow cavity and the heat exchange fluid flow cavity. Good sealing ensures that the heat carrier and the heat exchange fluid flow in their respective flow channels stably, avoids leakage, and thus improves the heat exchange efficiency. The heat carrier flow cavity and the heat exchange fluid flow cavity between two adjacent heat exchange units 601 are interconnected, so that the heat carrier and the heat exchange fluid can flow through each heat exchange unit 601 in turn to achieve sufficient heat exchange.

[0032] Reference Figure 1 and Figure 3 , distribution components 3 are arranged on the two end shells 1. The distribution component 3 includes a three-way pipe 302 arranged on the end shell 1 away from the connecting shell 2, and the three-way pipe 302 is connected to one of the heat exchange fluid flow cavities of the heat exchange unit 601. The three-way pipe 302 is made of high-temperature resistant and corrosion-resistant engineering plastics and is processed by injection molding. Its high-temperature resistant and corrosion-resistant properties ensure that it can work stably under different temperatures and chemical environments, thereby ensuring the safety and stability of fluid transportation. Two distribution units 303 are arranged on the three-way pipe 302, and an insulation pipe 301 is arranged between the corresponding two distribution units 303. The insulation pipe 301 is also made of high-temperature resistant and corrosion-resistant engineering plastics, which plays a role in reducing heat loss, ensuring that the temperature of the fluid is stable during the distribution process and is not excessively disturbed by the external ambient temperature.

[0033] Reference Figure 2 The distribution unit 303 includes a regulating valve 3032 and a flow sensor 3031 arranged on the three-way pipe 302. The flow sensor 3031 and the regulating valve 3032 are high-precision industrial-grade products, which are installed on the three-way pipe 302 after strict calibration and testing. The flow sensor 3031 can monitor the flow of the fluid in real time and feed the data back to the control system, and the regulating valve 3032 can accurately adjust the flow and distribution ratio of the fluid according to the instructions of the control system. In this way, the distribution component 3 can quickly and accurately adjust the mixing ratio of cold and hot air according to actual needs, and realize accurate control of the output air temperature.

[0034] Reference Figure 1 , a temperature probe 5 is provided at one end of the two end shells 1 away from each other. The temperature probe 5 uses a high-precision thermistor temperature sensor with an accuracy of ±0.1°C. The temperature probe 5 can accurately detect the temperature of the air inlet and outlet, and feed back the temperature signal to the control system in real time. The control system adjusts the mixing ratio and flow direction of the cold and hot air by controlling the regulating valve 3032 and the three-way valve 4 in the distribution component 3 based on the temperature data fed back by the temperature probe 5 and the preset temperature value, thereby achieving precise control of the output temperature of the equipment.

[0035] Reference Figure 2 A three-way valve 4 is also provided on the end shell 1, and the three-way valve 4 is connected to one of the heat exchange fluid flow cavities of the heat exchange unit 601. The three-way valve 4 is an electric three-way valve, which has a fast response speed and high control accuracy. The other two ends of the three-way valve 4 are respectively connected to the intelligent refrigeration circulation system and the intelligent heat pump circulation system. It can accurately adjust the flow direction and flow rate of the fluid according to the instructions of the control system, further optimize the conversion process of cold and hot air, and ensure that the equipment can quickly and stably output hot and cold air that meets the requirements.

[0036] The implementation principle of a cold and hot air converter in the embodiment of the present application is:

[0037] When the hot and cold air converter starts working, the temperature sensor 5 detects the temperature of the converter's air inlet and outlet in real time, and transmits the temperature signal to the control system. When the outlet temperature is lower than the preset value, the control system starts the distribution unit 303. The regulating valve 3032 blows out part of the heat-exchanged air through the insulation pipe 301 according to the flow data fed back by the flow sensor 3031 and the preset ratio, and part of the air is recycled to the inlet to mix with the newly entered air to be heat-exchanged. At the same time, the regulating valve 3032 accurately controls the newly entered fluid to be heat-exchanged and the recycled fluid to mix in a 1:1 ratio. This cycle can quickly adjust the temperature of the fluid to be heat-exchanged so that it quickly reaches the specified temperature.

[0038] During the heat exchange process, the heat carrier flows in the heat carrier flow cavity formed by the support plate 602 and the heat conducting plate 603, and the heat exchange fluid flows in the heat exchange fluid flow cavity formed by the heat conducting plate 603 and the heat conducting plate 603 and the heat conducting plate 603 and the end shell 1. The twisted band 6013 on the inner side of the conducting pipe 6011 separates it into two independent and mutually entangled flow channels. The heat carrier and the heat exchange fluid flow in the same pipe, and the staggered flow is achieved through the flow guide hole 6012, which greatly improves the heat exchange efficiency. At the same time, the blocking sheet 6014 blocks a specific flow channel, further optimizing the heat exchange path.

[0039] Through the connection between the quick connector A701 and the quick connector B702, two adjacent heat carrier flow cavities are interconnected, which facilitates the circulation of the heat carrier, and the number of connecting shells 2 can be flexibly customized according to actual needs, thereby making the entire device more compact and reducing the installation space.
