The invention discloses a self-power-generation refrigerating system for a vehicle-mounted power supply of a railway vehicle. The self-power-generation refrigerating system comprises a power box with the vehicle-mounted power supply, the top of the power box is of an open structure, a temperature sensor is arranged in the power box, a cooling fin A is arranged on the top of the power box, multiple refrigerating sheets are arranged on the top of the cooling fin A, the refrigerating end faces of the refrigerating sheets face the cooling fin A, the heat dissipation faces of the refrigerating sheets are back on to the cooling fin A, and the refrigerating sheets are communicated with a control power supply in series through an interlocking circuit and a reversing circuit. According to the self-power-generation refrigerating system for the vehicle-mounted power supply of the railway vehicle, when the temperature in the power box with the vehicle-mounted power supply is too high, the control power supply provides power for the refrigerating sheets so that the refrigerating sheets can cool the power box automatically; when the temperature in the power box with the vehicle-mounted power supply is within a safe temperature range, the refrigerating sheets conduct reverse charging on the control power supply so that energy consumption can be reduced.
Description
technical field [0001] The invention relates to the field of rail vehicle manufacturing, in particular to an on-board power supply self-generating refrigeration system for rail vehicles. Background technique [0002] The on-board power supply is the core technology of the new energy rail car powered by the on-board power supply. The heat dissipation of the on-board power supply affects the characteristics of the capacitor battery. Cooling fans are usually used to cool down the power supply. Starting from the rational use of waste gas for power generation and rapid cooling and cooling, this paper proposes the use of semiconductor cooling / heating fins for adaptive cooling of the vehicle power supply. [0003] The traditional fan heat dissipation process is --- During the use of the vehicle power supply, due to the existence of internal resistance, heat will be generated after the current flows through the power supply. The vehicle power supply is installed in the battery box, ...
