Built-in engine sump tank heater

Abstract

The invention discloses a built-in engine sump tank heater, and belongs to the technical field of engines. The built-in engine sump tank heater comprises a heating plate, wherein the heating plate comprises a bottom plate, an inner container, a heating workpiece and a cover plate; the heating workpiece is arranged on the inner container; the inner container is arranged between the bottom plate andthe cover plate; a heat conducting groove for placing the heating workpiece is arranged in the inner container; and wiring plates for communicating the heating workpiece and a power supply are arranged at two ends of the inner container. A bottom plate through hole is formed in the bottom plate; and an inner container through hole and a cover plate through hole are formed in the positions, corresponding to the bottom plate through hole, in the inner container and the cover plate. The heater is built in, so that the heat conducting time is shortened; the heater adopts the heating plate, the heating area of the heating plate is large, and the heater can be arranged according to the difference of oil sump appearance structures, so that the contact area of the heating workpiece and engine oilis increased, heat can be quickly recycled, and the heating efficiency is improved; and automobile engine oil is fast in heating, and after automobile engine oil is heated, the motor speed is normal,so that an automobile can be smoothly started up.

Description

technical field [0001] The invention relates to a built-in engine oil pan heater, which belongs to the technical field of engines. Background technique [0002] There are two main reasons why the vehicle is not easy to start in winter: 1. The temperature of the fuel is too low. Because diesel is compression ignited, the compression ratio needs to be increased in winter. The source of the compression ratio is determined by the speed of the starter motor. Due to the solidification of the engine oil in winter, the speed of the motor will drop, resulting in the compression ratio not increasing, and the vehicle is difficult to start. 2. In order for the starter to reach the predetermined speed, it is necessary to heat the oil in the oil pan. [0003] Existing heaters are designed to improve the oil operating environment of winter cars, but the heaters are mostly installed on the outer bottom of the oil pan for heating. For example, the heater adopts a ceramic thermistor heating ...

Problems solved by technology

[0003] Existing heaters are designed to improve the oil operating environment of winter cars, but the heaters are mostly installed on the outer bottom of the oil pan for heating. For example, the heater adopts a ceramic thermistor heating element and is installed on the bottom of the oil pan. The preheater adopts the preheating tube installed at the bottom of the oil pan, the preheating tube is connected to the output end of the inverter, and the heater is connected to the power supply to heat the oil pan, thereby heating the oil inside the oil pan. Although it can achieve a certain heating effect, because the heater is installed outside the oil pan, the heater cannot directly contact the oil and needs heat conduction to heat the oil, so the heating effect is not good, the heating time is long, and the energy consumption is high; in addition , the heater is designed as an internal resistance wire and an external bolt-shaped shell. This kind of heater is small in size and can be placed in the oil pan. However, due to the small size of the heater and its limited heating area, the heating effect is often not good.
