Heating system for driving equipment

Abstract

The invention, which belongs to the heating field, provides a heating system for driving equipment. The heating system is composed of a heater and a control board for controlling the heating process of the heater. An external temperature sensor is also connected to the control board. The heater includes a frame; and a silica gel heating piece for electrification heating is fixed at the frame. Besides, a temperature controlled switch is also arranged and is connected with a temperature controller and is connected with the control board by a cable. Because the silica gel heating piece is used inthe heating system, compared with the metal heat pipe heater and the PTC heater, the silica gel heating piece has advantages of small size, simple process, great convenience in forming and opening, low-temperature starting, and energy conservation and the like. In addition, the highest temperature that the heating piece can reach is set by using the silica gel heating piece or PET electric heating film; and the heater and the cabinet frame are in thermal connection by a heat-conducting rubber mat to realize the conduction type heating dissipation with uniform heat conduction and high heat conduction efficiency, so that a phenomenon that the adjacent core device is damaged due to the too high local temperature is avoided.

Description

technical field [0001] The invention belongs to the field of heating, in particular to a heating system for driving equipment. Background technique [0002] At present, in order to ensure the normal use of driving equipment in extremely cold regions, it is necessary to heat the cabinets in the driving equipment so that the electronic components in the cabinets are at a suitable temperature to work normally.

Problems solved by technology

[0003] The heating methods of existing cabinet equipment heaters are mainly based on electric heating tube heating and PTC heating. PTC heating is limited by the working temperature of the components and cannot be used in extremely cold regions. temperature, but thermal damage to the device can result when the thermostat fails

Moreover, the heating and processing requirements of electric heating tubes and PTC are very high, and it is difficult to realize special-shaped processing, and the heater itself is large in size, and a certain safe distance must be kept from the equipment, resulting in high cost

Therefore, it is not conducive to use in vehicle cabinets in extremely cold areas
