Embodiment Construction

[0054] The specific implementation manners of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0055] The heat dissipation system of the multi-gun high-power DC charging pile of the present invention is as follows: figure 1 As shown, the airflow direction inside and outside the cabinet is as follows: figure 1 As shown in the direction of the middle arrow, it includes the main control module and the cabinet body 3. On the right side of the cabinet body 3, there is an air inlet 1 (with a louver filter), and two sensors for detecting the ambient temperature are installed at the air inlet. It is connected to the main control module. There is an air outlet 2 (with louver filter) on the left side of the cabinet body 3. There are 5 cabinet fans of the same model at the air outlet 2. The charging pile is equipped with 5 charging guns (not in the figure 1 marked in ), there are 10 charging modules placed inside the cabinet (namely...

Abstract

The invention discloses an intelligent heat dissipation control method of a multi-gun large-power direct current charging pile. The intelligent heat dissipation control method of the multi-gun large-power direct current charging pile comprises the steps that charging modules are partitioned; all cabinet fans are partitioned according to the quantity and heat dissipation capacity; the total outputpower of each charging module region is obtained; rotation speed influence factor functions of all the cabinet fan regions are determined, the rotation speed influence factor function of the i cabinet fan region is Ri(Pi,Ta), and the rotation speed influence factor functions of all the cabinet fan regions constitute RPT; according to the rated fan rotation speed of the i cabinet fan region, the RPT and the wind pressure influence correction factor A, from the first rotation speed to the Yth rotation speed of the i cabinet fan region are obtained, and then from the first rotation speed to the Yth rotation speed of all the cabinet fan regions are obtained by repeatedly executing the above step; the maximum value from the first rotation speed to the Yth rotation speed of each cabinet fan region is selected as the final rotation speed of the cabinet fan region, the rotation speed is adjusted to complete intelligent heat dissipation control. The intelligent heat dissipation control method of the multi-gun large-power direct current charging pile has a good noise reduction effect and low in transformation cost, and technology promotion is convenient, and the control effect according to working conditions is good.

Description

technical field [0001] The invention belongs to the technical field of thermal management of electronic equipment, and relates to an intelligent heat dissipation control method of a multi-gun high-power DC charging pile. Background technique [0002] With the increasingly severe environmental problems and the aggravation of the global energy crisis, energy-saving and environmentally friendly new energy electric vehicles, as one of the important ways to solve such problems, have received widespread attention and attention from all over the world. Charging piles, as the basic supporting facilities for the energy supply of electric vehicles, play a vital role in the normal operation and popularization of electric vehicles. According to the development guidelines issued by relevant national departments, by 2020, the installation of decentralized charging piles will exceed 4.8 million to meet the charging needs of 5 million electric vehicles nationwide. [0003] In order to shor...
