Description
Technical Field
[0001] The utility model belongs to the technical field of hybrid power, and in particular relates to a cooling pipeline structure of a hybrid supercharger. Background Art
[0002] Conventional engine superchargers are usually cooled by lubricating oil. When the engine is stopped, the oil pump stops working, the supercharger cooling stops, and the supercharger will reheat. However, the special operating conditions of hybrid engines, such as sudden start and stop, and frequent start and stop, can easily cause the supercharger reheat temperature to be too high, causing the supercharger to rub the shell, poor lubrication, broken shaft and other faults. What is the technical solution? Figure 1 As shown, a delayed electronic water pump 6 is used to water-cool the supercharger 1, and the delayed cooling function of the electronic water pump is used to keep the supercharger reheating temperature within a normal operating range.
[0003] The delayed electronic water pump supercharger cools the supercharger through lubricating oil and coolant. After the engine is shut down, the lubricating oil will no longer circulate for cooling, and the electronic water pump will continue to work for a certain period of time before shutting down to ensure that the supercharger reheat temperature remains within the normal working range. The electronic water pump supercharger solution requires the design of special pipelines, wiring harnesses, brackets, etc., which has the problems of a large number of parts and high costs. The electronic water pump has a certain degree of magnetism, and after long-term operation, it will absorb iron filings in the coolant, causing water pump failure, so this solution also has the problem of high failure rate.
[0004] The information disclosed in the above background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as admitting or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

DETAILED DESCRIPTION
[0016] In order to explain the technical content, purpose and effect of the utility model in detail, the following is explained in combination with the embodiments and the accompanying drawings. In the description of this embodiment, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.
[0017] This embodiment discloses a hybrid supercharger cooling pipeline structure, referring to Figure 2 As shown, it includes a supercharger 1, a cylinder head 2, and a cylinder block 3.
[0018] The supercharger 1 comprises a supercharger water inlet 11 and a supercharger water outlet 13;
[0019] The cylinder body 3 includes a cylinder body water inlet 31, a cylinder body water return port 32, a cylinder body oil inlet 33, and a cylinder body oil return port 34;
[0020] The cylinder head 2 includes a thermostat seat water return port 21 and a cylinder head water outlet 22 which are arranged inside the cylinder head 2 .
[0021] Reference Figure 2 As shown, the supercharger water inlet 11 of the supercharger 1 is directly connected to the cylinder water intake port 31 of the cylinder block 3 through the water inlet pipe 12, the supercharger water outlet 13 of the supercharger 1 is connected to the thermostat seat water return port 21 in the cylinder head 2 through the water outlet pipe 14, the cylinder head water outlet 22 of the cylinder head 2 is connected to the cylinder water return port 32 of the cylinder block 3 through the pipeline through the water tank 4 and the main water pump 5, and the supercharger oil inlet 15 and the supercharger oil outlet 16 of the supercharger 1 are connected to the cylinder oil intake port 33 and the cylinder oil return port 34 of the cylinder block 3 through the oil inlet pipe 17 and the oil outlet pipe 18 respectively;
[0022] The cylinder head water jacket and the cylinder body water jacket between the cylinder head 2 and the cylinder block 3 are connected to allow the coolant to circulate, forming a circulation flow as a whole.
[0023] In this embodiment, the water outlet pipe 14 is arranged in a slanted manner from low to high along the direction from the supercharger water outlet 13 to the thermostat seat water return port 21.
[0024] The working principle of this embodiment is:
[0025] This embodiment eliminates the electronic water pump 6 based on the original need for delayed cooling, redesigns the corresponding pipelines, and ensures that the flow direction of the supercharger outlet pipe 14 is continuously upward, using the thermal siphon effect to achieve the purpose of delayed cooling. When the engine is running, the oil pump and the main water pump not dedicated to the supercharger will work to meet the cooling needs of the supercharger. When the engine is stopped, the oil pump and the main water pump will not work. Frequent start and stop of the hybrid engine will cause the supercharger heat recovery temperature to be too high, which cannot meet the cooling needs. Reference Figure 4 After shutdown, the coolant is heated in the water jacket of the intermediate body of the supercharger, and its volume expands, its density decreases and becomes lighter, and it is replenished by the surrounding cold liquid, so the coolant will continue to flow upward along the pipeline to form a cycle until the temperature of the supercharger is equivalent to the temperature of the coolant, and the thermal siphon effect stops, and the coolant no longer flows, achieving the purpose of delayed cooling. It solves the problems of the existing electronic water pump supercharger solution with a large number of parts, high cost, and high failure rate, while ensuring that the supercharger heat recovery temperature meets the requirements.
[0026] In addition, a hybrid supercharger of this embodiment, such as Figure 3 As shown, the supercharger 1 is characterized in that the water inlet pipe 12, the water outlet pipe 14, the oil inlet pipe 17, and the oil outlet pipe 18 are all pre-installed so as to be combined with the supercharger 1, and the water outlet pipe 14 is inclined from low to high along its end direction, and can be directly installed on the corresponding interfaces of the cylinder head 2 and the cylinder body 3 during assembly.
[0027] Although the present invention has been described in detail above with specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
