A heavy truck air conditioner intake structure

Abstract

The invention discloses a heavy truck air conditioning air inlet structure which comprises a radiator grille, wherein the radiator grille is connected with an air conditioning air inlet through a guide duct and comprises a grating and a rear cover plate matched with the grating; an air inlet is formed in the bottom of the grating; an air port is formed in the top end of the rear cover plate, directly faces the air inlet, and is under the air conditioning air inlet; the rear cover plate inclines towards the side away from the grating and form a first cavity with the grating in an encircling manner; the opening of the first cavity is largened from bottom up; the guide duct is a straight pipe inclining upwards; the bottom end of guide duct is connected with the air port; the top end of the guide duct inclines towards the air conditioning air inlet and is connected with the air conditioning air inlet. According to the scheme, the air duct and the first cavity form a double-deck cavity in an encircling manner, are of inclined structures, and are in smooth connection, so that airflows flowing in the grating are enabled to flow into the air inlet of an air conditioning assembly along an inclined plane, the air conditioning air inlet resistance is greatly reduced, and the operating efficiency of the air conditioning is improved.

Description

technical field [0001] The invention belongs to the field of heavy-duty truck air conditioners and their auxiliary accessories, and in particular relates to an air intake structure for heavy-duty truck air conditioners. Background technique [0002] Automobile air conditioning device is referred to as automobile air conditioner. It is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to the best state, provide the passengers with a comfortable riding environment, and reduce journey fatigue; create good working conditions for the driver and ensure safe driving Ventilation plays an important role. It generally includes a refrigeration device, a heating device, and a ventilation device. The air-conditioning ventilation device cools the air conditioner through the air intake at the front end. Ensuring the air intake volume of the air conditioner is crucial to the operating efficiency of the air conditioner. [0003] The s...

Problems solved by technology

[0003] The air inlet structure of the existing heavy truck air conditioner is usually as follows figure 1 As shown: the main unit of the air conditioner is arranged inside the cab. Due to the layout requirements of the main unit of the air conditioner, the vertical distance between the position of the air inlet B of the air conditioner assembly 2a and the air inlet A of the front grille is relatively large, and the air inlet B of the main unit is opposite to the horizontal distance L of the mask. Small; the wind coming in from the front grille 1a cannot effectively flow to the air inlet of the air conditioner, especially when the vehicle speed is high, the air inlet resistance of the air conditioner is relatively large, causing the air intake of the front grille to be blocked and lost, affecting the cooling effect of the air conditioner, and thus Affect air conditioner operating efficiency
