[0004] Through hydrophilic treatment, water is not easy to stay on the surface of the evaporator. Disadvantages: 1. It is time-limited. The hydrophilic solution is only attached to the surface of the evaporator. As time goes by, the effect of the solution will rapidly decrease; 2. After the solution evaporates, it will enter the cab with the wind, causing human discomfort; 3. Increase equipment cost and unit cost.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 3 A car air conditioning structure comprises: an air conditioning housing 1; a first channel 103, which is arranged on the air conditioning housing 1, the first end of the first channel 103 extends to the outside of the air conditioning housing 1, and the first end of the first channel 103 is an air outlet 101; a second channel 104, whose first end is connected to the second end of the first channel 103; a heater, which is installed on the second channel 104; a third channel 106, whose first end is connected to the second end of the second channel 104; an evaporator, which is installed in the third channel 106; and a blower, which is installed on the second end of the third channel 106. After the car is turned off, the evaporator blowing mode is turned on: at this time, the heater is turned on, the blower is reversed, and the air conditioning mode is the full hot foot blowing mode, and the cold air in the cabin is sucked back from the foot blowing air outlet into the HVAC. The wind will first be heated by the heater and then blown to the evaporator, and the water on the evaporator will be blown off. The water that cannot be blown off will become water vapor and be taken away by the hot air, and then sent to the outside of the cabin through the internal and external circulation dampers. It can eliminate the condensed water on the evaporator and solve the problem of white powder blowing in the car air conditioning.

[0031] A first partition plate 102 is provided in the air conditioning housing 1 , and the first partition plate 102 and the outer wall of the air conditioning housing 1 form a first channel 103 , which is a first channel for wind to pass through.

[0032] The first channel 103 extends from the first end to the second end of the air conditioning housing 1, thereby improving the structural utilization space of the air conditioning housing 1 and extending from the first side to the second side.

[0033] The second passage 104 extends from the second end to the first end of the air conditioning housing 1. The structure of the air conditioning housing 1 improves the space utilization and extends from the second side to the first side.

[0034] The second channel 104 is provided with a heater installation groove 105, and the heater is installed in the heater installation groove 105, which is used to install the heater to heat the wind.

[0035] The third passage 106 extends from the first end to the second end of the air conditioning housing 1, thereby improving the structural utilization space of the air conditioning housing 1 and extending from the first side to the second side.

[0036] The third channel 106 is provided with an evaporator mounting slot, and the evaporator is mounted on the evaporator mounting slot, which facilitates the installation of the evaporator. The blower is mounted on the second end of the air conditioner housing 1.

[0037] 1. Solve the problem of low inlet air temperature: When the system is blowing air, the heater is turned on and the mixing damper is in full heat state, so that the air blowing to the surface of the evaporator is hot air, which accelerates the evaporation of water on the evaporator.

[0038] 2. The fan is reversed, and the mode is full heat foot blowing mode, so that the cold air in the cabin can be sucked back from the foot blowing vents into the HVAC. The air will first be heated by the heater and then blown to the evaporator. Most of the water will be blown away, and the water that cannot be blown away will be taken away by the hot air and sent to the outside of the cabin through the internal and external circulation dampers. This method will not bring water vapor and heat into the cabin. Even if the owner enters the cabin for a short time, he will not feel hot.

[0039] 3. This logic is suitable for most vehicle systems on the market, such as wind-heated PTC systems (pure electric, hybrid or PHEV) and ordinary fuel systems (engine water heaters), because the heaters of ordinary fuel systems are hot in themselves. You only need to switch the mixing damper to the full hot state for the hot air to enter the circulation system.

[0040] Embodiment 2

[0041] The method of using the above-mentioned automobile air-conditioning structure is that after the car is turned off, the evaporator blowing mode is turned on: at this time, the heater is turned on, the fan is reversed, and the air-conditioning mode is the full-heat foot-blowing mode, and the cold air in the cabin is sucked back into the HVAC from the foot-blowing vents. The wind will first be heated by the heater and then blown to the evaporator. The water on the evaporator will be blown away, and the water that cannot be blown away will become water vapor and be carried away by the hot air, and then sent to the outside of the cabin through the internal and external circulation dampers.

[0042] 5 minutes after the car is turned off, the evaporator blowing mode is turned on and turned off after running for 2 minutes.

[0043] 1. Solve the problem of low inlet air temperature: When the system is blowing air, the heater is turned on and the mixing damper is in full heat state, so that the air blowing to the surface of the evaporator is hot air, which accelerates the evaporation of water on the evaporator.

[0044] 2. The fan is reversed, and the mode is full heat foot blowing mode, so that the cold air in the cabin can be sucked back from the foot blowing vents into the HVAC. The air will first be heated by the heater and then blown to the evaporator. Most of the water will be blown away, and the water that cannot be blown away will be taken away by the hot air and sent to the outside of the cabin through the internal and external circulation dampers. This method will not bring water vapor and heat into the cabin. Even if the owner enters the cabin for a short time, he will not feel hot.

[0045] 3. This logic is suitable for most vehicle systems on the market, such as wind-heated PTC systems (pure electric, hybrid or PHEV) and ordinary fuel systems (engine water heaters), because the heaters of ordinary fuel systems are hot in themselves. You only need to switch the mixing damper to the full hot state for the hot air to enter the circulation system.

[0046] After adopting the above structure, the condensed water on the evaporator can be eliminated, solving the problem of white powder blowing from the automobile air conditioner.
