Abstract
The utility model relates to a rain-proof louver of a high-speed train air conditioning system, and the rain-proof louver comprises a train compartment, an air return port, an evaporation fan, an evaporator, an air supply port, a rain-proof louver, a fresh air port with the rain-proof louver and a train compartment upper surface. The rain-proof louver has beneficial effects that simpleness in structure, practicability and reliability are realized, the problems that the rainy water is mixed with airflow to enter into the train compartment through a fresh air pipeline in rainstorm when the train is started, stopped and runs at a high speed to cause the rain leakage inside the compartment and worse environment inside the train can be solved; and meanwhile, the rain-proof louver also can be used for the fresh air port of other vehicle air conditioning system and house ventilation systems to prevent the rainy water brought by the airflow from entering the fresh air passage.
Description
Technical field
The utility model relates to a kind of rain-proof type louver, especially a kind of rain-proof type louver that is used for the high speed train a/c system.
Background technology
Along with the continuous development of science and technology, people's living standard is in continuous improvement, and people are also improving constantly the requirements for quality of living environment.Train is in the process that starts and stop, and the airflow on surface disturbance is bigger, and rainwater will be mixed in the air-flow and get into the compartment through the fresh wind tube road when running into heavy rain, causes roof leaking in the compartment.Generally, the rain-proof type louver on the high speed train all is common louver, and its inflow point's blade and exit blade tendency angle are 40 °～45 °; Can't well resist wind and rain, and, when the train high-speed cruising perhaps runs into heavy rain; Air-flow strong disturbance around driving; The surface forms negative pressure, and is accompanied by heavy rain and next strong wind, makes this problem more serious.Rainwater gets into after the new wind passage, not only because roof leaking has worsened environment by bus in the compartment, and influences the heat exchange efficiency of air-conditioning unit evaporator, increases energy consumption.
Summary of the invention
Inflow point's blade of common louver and exit blade tendency angle are 40 °～45 °; Can't well resist wind and rain, and, when the train high-speed cruising perhaps runs into heavy rain; Air-flow strong disturbance around driving; The surface forms negative pressure, and is accompanied by heavy rain and next strong wind, makes the roof leaking problem more serious.The utility model proposes a kind of rain-proof type louver that is used for the high speed train a/c system.
The technical scheme that the utility model adopted is; Comprise railway car, return air inlet, evaporation fan, evaporator, air outlet, rain-proof type louver, the fresh wind port that the rain-proof type louver is housed, railway car upper surface; The rain-proof type louver is installed in the railway car upper surface; Be made up of housing and the multi-disc blade that is fixed in housing, described inflow point blade tendency angle [alpha] is 40 °～45 °, and exit blade tendency angle beta is 20 °～25 °; The vertical distance L1 of adjacent two inflow points and exit lap be between adjacent two of the inflow point vertical distance L2 1/3～1/2; Described return air inlet and air outlet are loaded on the railway car two ends respectively, and the evaporator of flowing through after air is mixed by return air inlet and fresh wind port entering evaporation fan carries out interchange of heat and exports fresh cold air, and fresh cold air gets into the compartment by air outlet.
The beneficial effect of the utility model is simple in structure, practical reliable; Solved effectively train start, rainwater is mixed in the air-flow and gets into railway car through the fresh wind tube road when running into heavy rain in the stopped process and during high-speed cruising; Cause the problem of roof leaking deterioration environment inside car in the compartment; Simultaneously, the utility model also can be used for the fresh wind port of other carrier vehicle a/c systemes and house ventilation system, gets into new wind passage to prevent the rainwater that air-flow carries.
Description of drawings:
Fig. 1 implements structural representation for the utility model;
Fig. 2 is installed in the scheme drawing of railway car upper surface for the utility model;
Fig. 3 is the part sectional view of the utility model Fig. 2.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Extremely shown in Figure 3 by Fig. 1; A kind of high speed train a/c system rain-proof type louver that is used for; Comprise railway car 1, return air inlet 2, evaporation fan 3, evaporator 4, air outlet 5, rain-proof type louver 6, the fresh wind port 10 that rain-proof type louver 6 is housed, railway car upper surface 7, described rain-proof type louver 6 is installed in railway car upper surface 7, and rain-proof type louver 6 is made up of housing 8 and the multi-disc blade 9 that is fixed in housing 8; Described blade 9 inflow points tendency angle [alpha] is 40 °～45 °; Tendency angle beta in exit is 20 °～25 °, the vertical dimension distance L 1 of blade 9 adjacent two inflow points and exit lap be between two vertical distance L2 1/3～1/2, described return air inlet 2 is loaded on railway car 1 two ends respectively with air outlet 5; The evaporator 4 of flowing through after air is mixed by return air inlet 2 and fresh wind port 10 entering evaporation fans 3 carries out interchange of heat and exports fresh cold air; Fresh cold air reaches the effect of air regulation by air outlet 5 entering compartments 1, to improve the environment in the car.
Utilize the pressure on train surface under the different speed of a motor vehicle of FL1uent software (flowing and heat transfer numerical Analysis software) simulation train; Analyze the flow perturbation situation; Again according to the construction parameter of resh air requirement preliminary design rain-proof type louver; And combine the train trickle to test the reliability of verifying the result; The vertical distance L1 that calculates the high speed train maximum rainfall of different speed per hours (providing) blade 9 adjacent two inflow points and exit lap down through energy equation by meteorologic parameter be between adjacent two of the inflow point vertical distance L2 1/3～1/2, blade 9 inflow points tendency angle [alpha] is 40 °～45 °, it is 20 °～25 ° that the exit blade is inclined to angle beta; Common fresh wind port rain-proof type louver does not have the vertical distance L1 and the exit blade tendency angle beta of lap, and only maintaining certain tendency angle [alpha] is 45 °.
The utility model rain-proof type louver also can use on other equipment; For example full-sized car air-conditioner fresh air inlet, factory's ventilation ventilation inlet etc.; Prevent that the rainstorm weather rainwater from getting into the heat exchange efficiency that air conditioner ventilating system worsens indoor environment and air-conditioning unit evaporator, increases energy consumption.
