Description

Technical Field

[0001] The present invention relates to a built-in heating device, belonging to the technical field of engines. Background Art

[0002] The main function of the oil-water separator for automobiles is to remove moisture in diesel fuel and pre-filter the fuel to reduce the failure of fuel injectors and extend the service life of the engine. The principle of removing moisture in diesel fuel is mainly based on the density difference between water and fuel, and a separator that uses the principle of gravity sedimentation to remove impurities and moisture. When the ambient temperature is below zero degrees Celsius, the fluidity of the diesel fuel in the oil-water separator becomes poor, and the diesel fuel cannot be supplied to the engine in a timely manner, affecting the normal operation of diesel vehicles. Existing devices for heating the oil-water separator are generally arranged on the separator housing, and heat is conducted to the inside of the separator through the housing by heat conduction. In the case of extremely low ambient temperatures, the heat dissipation of this heating method is relatively large, so the heating efficiency and the heating rate are low, and it cannot meet the use requirements of automobile engines.

At the same time, the heat generated by heating is transmitted from the bottom upwards, which can heat the diesel fuel in the oil-water separator in a timely and effective manner, making the heating effect reach the best, and having the advantages of low power consumption and high thermal efficiency. At the same time, it can be connected to the power supply of the vehicle to make full use of the electricity of the vehicle itself for heating, effectively solving the problems of diesel fuel waxing when cold and diesel vehicle breakdowns.

[0022] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0023] Please refer to Figures 1 to 4 As shown, an in - built heating device includes a hollow adapter 2, which is connected to the water outlet at the bottom of the oil - water separator. The material of the hollow adapter 2 is metal, so as to ensure the connection strength with the housing 1. A flexible heating element 7 is provided inside the hollow adapter 2. Since a filter screen is provided inside the housing of the oil - water separator, the gap between the filter screen and the bottom water outlet is generally 1 cm - 2 cm. By setting the heating element 7 to be flexible, without changing the original structure of the oil - water separator, the heating element 7 can be smoothly placed into the gap and the heating effect can be ensured. The hollow structure facilitates the heating element 7 to pass through the adapter 2 and enter the housing 1, and can accommodate the extra - length heating element 7, reducing the size requirements for the heating element 7. One end of the heating element 7 extends into the housing 1 of the oil - water separator, and the other end is connected to a power source.

[0024] A fastening assembly 4 is provided on the side wall of the hollow adapter 2. The heating element 7 passes through the fastening assembly 4 and is electrically connected to a connecting wire 8. A connector 6 is provided at the end of the connecting wire 8. A corrugated pipe 5 is sleeved outside the connecting wire 8, which can avoid damage to the connecting wire 8 and improve the service life of the heating device. The fastening assembly 4 includes a hollow connecting piece 4 - 1 with threads at both ends. One end of the hollow connecting piece 4 - 1 is threadedly connected to the adapter 2, and the other end is connected to a locking piece 4 - 3. A guiding piece 4 - 2 is provided inside the hollow connecting piece 4 - 1. A boss is provided on the guiding piece 4 - 2. The locking piece 4 - 3 fixes the boss of the guiding piece 4 - 2 inside the hollow connecting piece 4 - 1. A through - hole for accommodating the heating element 7 or the connecting wire 8 is provided on the guiding piece 4 - 2, so as to ensure the stability of the installation of the connecting wire 8 and the heating element 7 and avoid breakage during vehicle driving.

[0025] The heating element 7 is arranged in a spiral shape inside the housing 1 at the bottom of the oil - water separator. Since the heating element 7 is installed in the housing 1 of the oil - water separator through the adapter 2, when the adapter 2 is threadedly rotated and connected to the housing 1, the heating element 7 rotates together and is arranged in a spiral shape inside the housing 1, increasing the heating area of the heating element 7 and ensuring the heating efficiency.

[0026] The heating element 7 can be a heating wire.

[0027] In a preferred embodiment, the heating element 7 is connected to the signal sensor through a connector 6. The signal sensor can be a temperature sensor. The heating element 7 is controlled to heat through the stability feedback of the temperature sensor, ensuring the timeliness of heating and saving energy.

[0028] In an alternative embodiment, the heating element 7 can also be stacked at the bottom of the housing 1.

[0029] A sealing bolt 3 is connected to the end of the hollow adapter 2, and a water level sensor is provided inside the sealing bolt 3. The water generated in the oil-water filter flows into the hollow adapter 2. When the water level sensor detects that the water in the hollow adapter 2 exceeds the set value, the water is directly discharged through the sealing bolt 3 to avoid accumulation in the hollow adapter 2 and ensure the oil-water separation function of the oil-water separator.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
