Electric heating rainwater separator of air conditioning unit for railway vehicle

Abstract

The invention discloses an electric heating rainwater separator of an air conditioning unit for a railway vehicle. The electric heating rainwater separator is good in snow melting effect. The electric heating rainwater separator comprises a framework, a plurality of first waterproof filter cores arranged at the front end of the framework in one row, and a plurality of second waterproof filter cores arranged in the framework behind the first waterproof filter cores in one row, third waterproof filter cores are uniformly arranged between the first waterproof filter cores and second waterproof filter cores, a first water baffle plate is arranged at the rear end of each third waterproof filter core, a second water baffle plate is arranged at the rear end of each first waterproof filter core, ventilation gaps remain between the first waterproof filter cores, second waterproof filter cores and third waterproof filter cores, electric heating pipes are arranged in the first waterproof filter cores, and a wiring protection box connected with the electric heating pipes is arranged at the front end of the framework. The electric heating rainwater separator of the air conditioning unit for the railway vehicle has advantages that the snow or ice water can be melted timely, the rainproof effect and air inlet effect are good, the normal work of the air conditioning unit for the railway vehicle is guaranteed, and the energy consumption of the air conditioning unit for the railway vehicle is lowered.

Description

technical field [0001] The invention relates to a rail vehicle air conditioning unit, in particular to an electrically heated rainwater separator for a rail vehicle air conditioning unit. Background technique [0002] During the use of the rail vehicle air-conditioning unit, it is necessary to install rainwater separators at the air inlets on both sides of the rail vehicle air-conditioning unit to allow the rail vehicle air-conditioning unit to ventilate and prevent rainwater from entering. The structure of the existing rainwater separator includes: a frame, a first waterproof filter element and a second waterproof filter element arranged in the frame, and a ventilation gap is arranged between the first waterproof filter element and the second waterproof filter element. The existing rainwater separator has poor rain-proof and wind-intake effects, and cannot guarantee the normal operation of the rail vehicle air-conditioning unit, resulting in higher energy consumption of th...

AI Technical Summary

Problems solved by technology

The existing rainwater separator has poor rain-proof and wind-intake effects, and cannot guarantee the normal operation of the rail vehicle air-conditioning unit, resulting in higher energy consumption of the rail vehicle air-conditioning unit, especially in areas where the environment is relatively cold and harsh, such as Lanzhou in my country. On the new line, due to the low temperature, snow is easy to accumulate and freeze on the air-conditioning unit of the rail vehicle, which affects the ventilation of the rainwater separator
