The oil filter heating unit quickly heats the engine oil through stainless steel electric heating. The electric heating engine oil pipeline heats the coolant through an integrated electric heating wire in the rubber pipeline. The coolant drives the oil disturbing unit to mix and heat the cold and hot engine oil.

Abstract
Description
Technical Field
[0001] The invention belongs to the field of engines, and in particular relates to an oil heating device for an oil box. Background Art
[0002] In low temperature environment, when the vehicle starts, it is difficult to ignite due to the low temperature of the engine body and the intake air. At the same time, the coolant and lubricating oil temperature is low, and the starting resistance is large, which makes it difficult to start the engine. When the ambient temperature is lower than a certain requirement, the oil must be fully heated in order to reduce the friction and wear of engine components and improve the starting performance. The traditional oil heating system arranges an oil heating pipe in the oil tank. The coolant heated by the heating pot flows inside the heating pipe. The oil is heated by the heat exchange between the coolant and the oil. However, the viscosity of the oil is large and the fluidity is poor at low temperatures. The oil temperature around the oil heating pipe often rises, and the cold oil in the oil tank is in a plasticized state and cannot be replenished to the heating area of the oil heating pipe in time, resulting in a long oil heating time that cannot meet the cold start requirements of the engine. Based on the existing oil tank structure, the oil heating structure is improved to achieve rapid engine starting in low temperature environment. Summary of the invention
[0003] In view of this, the present invention aims to provide an oil tank oil heating device to meet the requirement of rapid starting of vehicles in low temperature environments, while having a compact structure and occupying a small space.
[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:
[0005] An oil heating device for an oil box comprises an oil box and an oil filter electric heating unit installed inside thereof, an oil disturbance unit, an oil heat exchanger, and an electrically heated oil pipeline. The oil filter electric heating unit comprises an oil filter and an oil filter electric heating mechanism. The oil filter electric heating mechanism is used for quickly heating the oil retained in the oil filter. A stainless steel electric heating sheath is installed outside the oil filter. The electrically heated oil pipeline is used for heating the coolant. The coolant drives the driving impeller inside the oil disturbance unit to further disturb the oil around the oil heat exchanger, so that the cold oil and hot oil in the oil box are remixed.
[0006] Furthermore, the outside of the oil filter is coated with stainless steel for electric heating.
[0007] Furthermore, under the voltage of 16V to 32V, the oil filter electric heating mechanism can quickly heat the oil retained in the oil filter within 20 minutes.
[0008] Furthermore, the electrically heated oil pipeline is a rubber pipeline, and an electric heating wire is integrated inside the rubber.
[0009] Furthermore, the oil disturbance device includes a driving impeller, a reduction mechanism, and a disturbance mechanism. When the engine oil tank starts to be heated, the heated coolant flows through the driving impeller, driving the driving impeller to rotate. After being decelerated by the reduction mechanism, the speed of the disturbance mechanism is controlled at a set speed and begins to disturb the oil around the oil heat exchanger in the oil tank, so that the cold and hot oil in the oil tank are reheated and mixed.
[0010] Furthermore, the oil heat exchanger is an aluminum brazed heat exchanger.
[0011] Furthermore, the heated coolant can flow inside the oil heat exchanger.
[0012] Furthermore, heat dissipation fins are installed outside the oil heat exchanger.
[0013] Compared with the prior art, the oil tank oil heating device of the present invention has the following advantages:
[0014] (1) The oil tank oil heating device of the present invention has low power consumption and does not increase the burden on the battery of the entire vehicle. By electrically heating the oil filter and the oil pipeline, the oil flow resistance during cold start of the engine is greatly reduced, thereby effectively reducing the power consumption of the pre-lubrication pump.
[0015] (2) The oil heating device for the oil tank of the present invention adopts the oil disturbance device without introducing an additional power system, so that the cold oil and the hot oil in the oil tank are fully mixed, thereby effectively shortening the time for heating the oil in the oil tank.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0024] An oil box oil heating device, such as Figure 1 As shown, it includes an oil box and an oil filter electric heating unit 1, an oil disturbance unit 2, an oil heat exchanger 3, and an electric heating oil pipeline 4 installed inside. The oil filter electric heating unit 1 includes an oil filter 101 and an oil filter electric heating mechanism 102. The oil filter electric heating mechanism 102 is used to quickly heat the oil retained in the oil filter 101. A stainless steel electric heating sheath is installed outside the oil filter 101; the electric heating oil pipeline 4 is used to heat the coolant. The coolant drives the driving impeller inside the oil disturbance unit 2 to disturb the oil around the oil heat exchanger 3, so that the cold oil and hot oil in the oil box are reheated and mixed.
[0025] The oil filter electric heating unit 1 includes an oil filter 101 and an oil filter electric heating mechanism 102. The oil filter electric heating mechanism 102 is used to heat the oil filter 101. The oil filter 101 is externally installed with a stainless steel electric heating package. Under a voltage of 16V to 32V, the oil retained inside can be quickly heated within 20 minutes. The electric heating oil pipeline 4 is a rubber pipeline with an integrated electric heating wire inside the rubber. The electric heating oil pipeline 4 is used to provide energy to the oil filter electric heating mechanism.
[0026] The oil disturbance device 2 includes a driving impeller 201, a speed reduction mechanism 202, and a disturbance mechanism 203. When the engine oil tank starts to be heated, the heated coolant flows through the driving impeller 201, driving the driving impeller 201 to rotate. After being decelerated by the speed reduction mechanism 202, the disturbance mechanism 203 controls the speed at a suitable speed and starts to disturb the oil around the oil heat exchanger 3 in the oil tank, so that the cold oil and the hot oil in the oil tank are reheated and mixed.
[0027] The oil heat exchanger 3 is an aluminum brazing heat exchanger installed inside the oil tank. The heated coolant flows inside, and heat dissipation fins are installed outside to increase the heat transfer area.
[0028] The working principle of an oil box oil heating device is as follows:
[0029] When the engine receives the instruction to prepare for cold start, the electric heating oil pipeline 4 and the oil filter electric heating device 102 start to supply power, and the oil pipeline and the oil filter 101 start to be heated. The coolant heated by the heating pot flows through the driving impeller 201, is decelerated by the deceleration structure 202, and the driving disturbance mechanism 203 starts to work to disturb the oil in the oil tank. After passing through the driving impeller 201, the coolant reaches the oil heat exchanger 3 to heat the oil in the oil tank.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
