Abstract

The invention belongs to the technical field of locomotive warm air parts, and discloses a warm air blower circuit and a cab warm air blower thereof. The warm air blower circuit comprises a control loop and a heating loop, wherein the control loop comprises a contactor coil, the heating loop comprises a heating branch circuit and a draught fan branch circuit which are connected in parallel, the heating branch circuit comprises a contactor terminal and a heating element connected with the contactor terminal in series, and the draught fan branch circuit comprises a draught fan used for dispersing heat, which is generated by the heating element, to the exterior of a case. A contactor is used for controlling the heating element in the heating loop to heat, low pressure control over high pressure is realized, and the circuit is guaranteed to be stable so as to ensure the heating element to keep working normally; a finned electric heating pipe is adopted, the heating area is large, the heatloss is small, and the warm air blower circuit has the advantages of fast temperature rise, uniform heating, high electricity-heat transformation efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of locomotive heater components, in particular to a heater circuit and a driver's cab heater. Background technique [0002] The cab heating device is an important part of the locomotive cab. It is used to cope with the cold in winter. It can provide a comfortable working environment for the crew and is beneficial to the physical and mental health of the crew. However, due to the small space and complicated layout of the cab, heating The installation of the device has relatively large limitations. Most of the heating equipment used on existing locomotives is installed on the wall, which not only occupies part of the space in the locomotive cab, but also affects the overall aesthetics of the cab, and is not conducive to heating Equipment overhaul and maintenance. [0003] In addition, the current heating equipment (air heater) mainly includes a shell, with a hot air outlet on the side wall of the shell, an el...
