Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to an integrated energy-saving evaporator for automotive air conditioning. Background Technology

[0002] A car air conditioner is an air conditioning system installed in a vehicle to provide a comfortable interior environment for passengers. It has multiple functions. In terms of cooling, it uses components such as the compressor, condenser, and evaporator to work together to transfer heat from the vehicle interior to the outside, lowering the interior temperature and providing coolness in the hot summer. The heating function utilizes the heat from the engine coolant, which is then delivered to the vehicle interior via the heater core and fan, keeping the cabin warm and comfortable in cold weather.

[0003] Meanwhile, car air conditioning can also regulate air humidity and air circulation. It can filter dust, pollen, and other impurities from the air, purifying the air inside the car and keeping it fresh. By adjusting the fan speed and direction, it can meet the different airflow needs of passengers. In addition, some high-end car air conditioning systems also have zone control functions, allowing different areas to be set with independent temperatures, meeting the personalized temperature requirements of different passengers and comprehensively improving the comfort of the driving experience.

[0004] In traditional automotive air conditioning systems, the evaporator is a key component responsible for evaporating refrigerant and absorbing heat to lower the temperature of the air inside the vehicle. However, to achieve the required heat exchange efficiency, existing evaporators use a fan to blow air onto their outer surface for heat exchange. But when using a fan to blow air onto the evaporator's outer surface for heat exchange, impurities in the air tend to accumulate on the heat sink fins, leading to poor airflow, further reducing heat exchange efficiency, increasing energy consumption, and making cleaning and maintenance more difficult. Utility Model Content

[0005] The purpose of this invention is to provide an integrated energy-saving evaporator for automotive air conditioning, in order to achieve the required heat exchange efficiency, existing evaporators use a fan to blow air onto the outer surface of the evaporator for heat exchange. However, when using a fan to blow air onto the outer surface of the evaporator for heat exchange, impurities in the air tend to accumulate on the heat sink fins of the evaporator, resulting in poor air circulation, further reducing heat exchange efficiency, increasing energy consumption, and making cleaning and maintenance difficult.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes an evaporator body, which is composed of heat sinks, refrigerant pipes and a shell integrated into one unit. The outer end of the heat sinks is wavy, and the refrigerant pipes adopt a microchannel flat tube design. An installation enclosure is fixedly installed on the outer end of the evaporator body. An installation panel is fixedly installed on the front end of the evaporator body. An air intake channel is fixedly connected to the front end of the installation panel. A heat exchange fan for blowing heat is fixedly installed on the inner side of the air intake channel. A rotating ring is rotatably connected to the front end of the air intake channel via a rotating shaft. A filter screen for filtering air is detachably fixedly installed on the front end of the rotating ring. A drive motor is fixedly installed on the front side of the evaporator body. A transmission gear is fixedly installed on the transmission shaft part of the front end of the drive motor. A transmission gear ring is meshed with the outer end of the transmission gear. An L-shaped mounting bracket is fixedly installed on the outer side of the installation panel. An electric telescopic rod is fixedly installed through the inner side of the L-shaped mounting bracket. A telescopic plate is fixedly installed on the inner side of the electric telescopic rod. A cleaning brush for cleaning the outer end of the filter screen is detachably fixedly installed on the inner side of the telescopic plate.

[0007] Preferably, the outer shell is made of a high-strength, lightweight alloy material, the outer surface of the heat sink is coated with a hydrophilic and antibacterial coating, and the refrigerant pipeline is arranged in a serpentine shape inside the evaporator body.

[0008] Preferably, the four corners of the installation enclosure are provided with mounting holes for installing and fixing the installation enclosure.

[0009] Preferably, there are two air intake channels, symmetrically arranged on both sides of the front end of the mounting panel. The transmission gear ring is fixedly installed on the outer end of the rotating ring, and the inner sides of the transmission gear ring mesh with each other for transmission.

[0010] Preferably, there are two L-shaped mounting brackets, which are symmetrically distributed on the outer side of the mounting panel.

[0011] Preferably, limiting slide rods are fixedly installed on both sides of the outer end of the telescopic plate, and the outer side of the limiting slide rods is movably connected to the inner side of the L-shaped mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention optimizes the structure of the heat sink and the design of the refrigerant piping, increases the heat exchange area, and reduces the thermal resistance, enabling the evaporator body to achieve the set cooling effect in a shorter time, thus improving the overall performance of the automotive air conditioning system. The antibacterial coating on the surface of the heat sink effectively inhibits the growth of bacteria and mold, while the hydrophilic coating improves the dehumidification effect, providing a healthier and more comfortable environment for passengers in the vehicle. This invention also controls the activation of a drive motor. When the drive motor is activated, it drives a rotating ring to rotate, which in turn drives the filter screen to rotate. As the filter screen rotates, an electric telescopic rod extends, causing a telescopic plate to move inward in a straight line. This inward movement of the telescopic plate causes a cleaning brush to move inward towards the filter screen, thus cleaning the rotating filter screen. This prevents impurities from blocking the filter screen and causing blockage, thereby filtering and blocking air in the air intake channel while facilitating the cleaning of impurities blocked by the filter screen.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3This utility model provides a technical solution for an integrated energy-saving evaporator for automotive air conditioning: It includes an evaporator body 1, which is composed of heat sink 101, refrigerant piping 102, and a shell 103 integrated into a single unit. The shell 103 is made of a high-strength, lightweight alloy material, which has good thermal conductivity and corrosion resistance, effectively protecting the internal structure of the evaporator body 1 and improving heat exchange efficiency. The outer end of the heat sink 101 is wavy, increasing the contact area between the heat sink 101 and the air, thus improving heat exchange efficiency. The outer surface of the heat sink 101 is coated with a hydrophilic and antibacterial coating. The hydrophilicity... The condensate spreads rapidly on the surface of the heat sink 101, forming a uniform water film, which accelerates the evaporation of water and improves the dehumidification effect. The antibacterial properties can inhibit the growth of bacteria and mold, improving the air quality inside the vehicle. The refrigerant pipe 102 adopts a microchannel flat tube design. The microchannel flat tube has the characteristics of small inner diameter and many channels, which can increase the contact area between the refrigerant and the pipe wall of the refrigerant pipe 102, improve the evaporation efficiency of the refrigerant. At the same time, the pipe wall of the microchannel flat tube is thin and has low thermal resistance, which is conducive to the rapid heat transfer. The refrigerant pipe 102 is arranged in a snake shape inside the evaporator body 1, so that the refrigerant can fully exchange heat with the heat sink 101. An installation enclosure 2 is fixedly installed on the outer end of the evaporator body 1, and the four corners of the installation enclosure 2 have through holes for fixing the installation enclosure 2. An installation panel 3 is fixedly installed on the front end of the evaporator body 1. An air intake channel 4 is fixedly connected to the front end of the installation panel 3. There are two air intake channels 4, which are symmetrically arranged on both sides of the front end of the installation panel 3. A heat exchange fan 15 for blowing heat exchange is fixedly installed on the inner side of the air intake channel 4. A rotating ring 5 is rotatably connected to the front end of the air intake channel 4 via a rotating shaft. A filter screen 6 for filtering air is detachably fixedly installed on the front end of the rotating ring 5. A drive motor 7 is fixedly installed on the front side of the evaporator body 1. A transmission gear 8 is fixedly installed on the transmission shaft part of the front end of the drive motor 7. A transmission gear ring 9 is engaged with the rotating ring 5 and is fixedly installed on the outer end of the rotating ring 5. The inner sides of the transmission gear rings 9 mesh with each other for transmission. An L-shaped mounting bracket 10 is fixedly installed on the outer side of the mounting panel 3. There are two L-shaped mounting brackets 10, which are symmetrically distributed on the outer side of the mounting panel 3. An electric telescopic rod 11 is fixedly installed through the inner side of the L-shaped mounting bracket 10. A telescopic plate 12 is fixedly installed inside the electric telescopic rod 11. Limiting slide rods 13 are fixedly installed on both sides of the outer end of the telescopic plate 12. The outer side of the limiting slide rod 13 is connected to the inner side of the L-shaped mounting bracket 10 in a close fit, so that the telescopic plate 12 can be linearly moved and limited by the limiting slide rod 13. A cleaning brush 14 for cleaning the outer end of the filter screen 6 is detachably fixedly installed inside the telescopic plate 12.

[0017] Working principle: In use, this utility model increases the heat exchange area and reduces the thermal resistance by optimizing the structure of the heat sink 101 and the design of the refrigerant pipeline 102, so that the evaporator body 1 can reach the set cooling effect in a shorter time, thereby improving the overall performance of the car air conditioning system. The antibacterial coating on the surface of the heat sink 101 can effectively inhibit the growth of bacteria and mold, while the hydrophilic coating improves the dehumidification effect, providing a healthier and more comfortable environment for passengers in the car. By controlling the activation of the heat exchange fan 15, airflow is directed onto the heat sink 101 for heat exchange. During this process, the airflow through the intake channel 4 is filtered and blocked by the filter screen 6, preventing impurities from accumulating on the heat sink 101. Simultaneously, by controlling the activation of the drive motor 7, the transmission gear 8 rotates. This rotation of the transmission gear 8 meshes with and drives the transmission gear ring 9, which in turn rotates the rotating ring 5. The rotating ring 5, in turn, drives the filter screen 6. When the filter screen 6 rotates, the electric telescopic rod 11 extends by control. When the electric telescopic rod 11 extends, it drives the telescopic plate 12 to move in a straight line inward. When the telescopic plate 12 moves in a straight line inward, it drives the cleaning brush 14 to move in a straight line inward and approach the filter screen 6. When the cleaning brush 14 moves in a straight line inward and approaches the filter screen 6, it can clean the rotating filter screen 6, avoiding the situation where impurities blocked at the outer end of the filter screen 6 cause the filter screen 6 to become clogged. Thus, it can filter and block the air in the air intake channel 4, and at the same time facilitate the cleaning of impurities blocked by the filter screen 6.
