Equipment for detecting sealing performance of vehicle air conditioner outdoor unit through wind pressure

Abstract

The invention relates to the technical field of train air conditioner sealing performance detection and discloses equipment for detecting the sealing performance of the vehicle air conditioner outdoorunit through the wind pressure. The equipment includes a vehicle body; a sliding rail is fixedly connected to the top of the vehicle body; an airflow channel is fixedly connected to the sliding rail;a shaft sleeve is movably connected into the airflow channel; air holes are formed in the surface of the shaft sleeve; a blocking plate is movably connected to the position, above the shaft sleeve, in the airflow channel; and supporting plates are slidably connected to the surface of the sliding rail and located on the two sides of the airflow channel. The motion process is a motion process in agood sealing state; if the sealing performance is poor, airflow flows into the vehicle body from the joint of the supporting plates and the vehicle body; and the airflow flowing in from a telescopic rod is reduced, so that the airflow force borne by an air pressure plate is increased, the supporting plate is pushed to slide on the surface of the sliding rail, the position of the supporting platesis changed, it shows the sealing performance is poor, and the effect of monitoring the sealing performance of the air conditioner in real time by utilizing the air pressure without parking is achieved.

Description

technical field [0001] The invention relates to the technical field of train air conditioner sealing performance detection, in particular to a device for detecting the sealing performance of an external unit of a vehicle air conditioner by using wind pressure. Background technique [0002] The automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air in the vehicle compartment. It is installed on the vehicle to improve the comfort of the vehicle's drivers and passengers. [0003] According to the characteristics of the car or train, some components that need to be dissipated are placed outside the car body to reduce the impact on the temperature inside the car. The outer casing is equipped with the air inlet and outlet of the condensing fan, which is convenient for the vehicle. Intake and exhaust. [0004] The airtightness of the shell placed outside the vehicle body has become an item that must be tested every day. The air-condition...

Problems solved by technology

[0004] The airtightness of the casing placed outside the car body has become an item that must be tested every day. The air-conditioning effect is directly affected by the airtightness of the outdoor cavity. In the prior art, the airtightness test needs to be done after the vehicle is stopped. Use special testing instruments for detection. If the vehicle is running, if there is a problem of poor sealing, it will be difficult to detect it, and it is prone to water seepage or insufficient air intake. Therefore, a vehicle air conditioner that uses wind pressure to detect The sealing equipment of the external unit came into being
