Description

Technical Field

[0001] This invention relates to the field of diesel engine and related components, specifically to a high-efficiency cooling system for diesel engines. Background Technology

[0002] A diesel engine is an internal combustion engine that uses diesel fuel as its driving fuel. The heat generated by a diesel engine during operation is usually dissipated through a water cooling system to ensure the engine's standard internal operating temperature. A conventional diesel engine water cooling system is a water tank structure set in the engine casing. Water is added to the tank, and the boiling point of water is 100 degrees Celsius, which stabilizes the engine's operating temperature. However, this type of water cooling system can only add a single type of coolant to the tank, and the tank design must be compatible with the diesel engine's external structure. This means that the structure of this cooling system needs to be designed for each model of diesel engine. Furthermore, this passive cooling method has low heat dissipation and heat conduction efficiency. Therefore, an optimized circulating liquid cooling structure needs to be designed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a high-efficiency cooling system for diesel engines. This system incorporates multiple water tanks and heat dissipation pipes, along with an active circulation system and a series-parallel control unit. This allows for the selection of different operating modes or the use of different liquid coolants based on different functions, thereby achieving efficient heat dissipation for the diesel engine. Furthermore, this device features a modular design, enabling it to be used with different models of diesel engines.

[0048] The circulating water inlet pipe 4-2 is connected in series at the inlet end of the heat dissipation pipe 2, and the other end of the circulating water inlet pipe 4-2 is connected in series at the outlet end of the water distributor 4-1.

[0049] The circulating water outlet pipe 4-3 is connected in series at the outlet end of the heat dissipation pipe 2, and the other end of the circulating water outlet pipe 4-3 is connected in series at the branch inlet end of the water distributor 4-1.

[0050] The guide pipe 7 is set between the circulating water outlet pipe 4-3 and the circulating water inlet pipe 4-2. The upper end of the guide pipe 7 is connected to the circulating water outlet pipe 4-3, and the other end of the guide pipe 7 is connected to the circulating water inlet pipe 4-2 on the adjacent heat dissipation pipe 2 in the lower layer.

[0051] Three-way solenoid valve 10, two of the three-way solenoid valves 10 are connected in series at both ends of the guide pipe 7, one of the three-way solenoid valves 10 in one group is connected in series on the circulating water outlet pipe 4-3, and the other three-way solenoid valve 10 is connected in series on the circulating water inlet pipe 4-2.

[0052] The circulating solenoid valve 8 is connected in series on the circulating water inlet pipe 4-2 and the circulating water outlet pipe 4-3, and the circulating solenoid valve 8 is located between the three-way solenoid valve 10 and the water distributor 4-1.

[0053] Connecting pipe 4-4, there are two connecting pipes 4-4, one of which is connected in series at the main inlet end of the water distributor 4-1, and the other connecting pipe 4-4 is connected in series at the main outlet end of the water distributor 4-1.

[0054] An internal circulating water pump 6 is mounted on the side of the distributor 4-1. The first inlet end of the internal circulating water pump 6 is connected in series with the main inlet pipe 3-1 through a pipe. The first outlet end of the internal circulating water pump 6 is connected in series with the main outlet pipe 3-3 through a pipe. The connecting pipe 4-4 on the main inlet end of the distributor 4-1 is connected in series with the outlet end of the internal circulating water pump 6.

[0056] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0057] When using this device, the heat dissipation pipe 2 is attached to the radiator housing of the diesel engine via the heat spreader plate 5. The corresponding cooling and functional reagents are added to the water tank 1. The internal circulation water pump 6 is connected to the control system. The internal circulation water pump 6 draws water through the main inlet pipe 3-1, which then draws water from the water tank 1 through the branch inlet pipe 3-2. The internal circulation water pump 6 sends the water drawn from the main inlet pipe 3-1 into the distributor 4-1, and then through the distributor 4-1 into the circulating water inlet pipe 4-2. The external reagent is fed into the heat dissipation pipe 2 for circulation. The reagent in the heat dissipation pipe 2 absorbs heat. Then, the waste liquid in the heat dissipation pipe 2 is discharged into the water distributor 4-1 through the circulation outlet pipe 4-3. Then, the internal circulation water pump 6 draws the waste liquid in the water distributor 4-1 and sends it into the main outlet pipe. The waste liquid is sent into the original reagent water tank 1 through the main outlet pipe and the outlet branch pipe. In this way, the reagent circulates and absorbs heat in the heat dissipation pipe 2, and the heated reagent returns to the water tank 1 to cool down.

[0058] When the reagent in the corresponding water tank 1 is drawn, the water supply solenoid valve 9 of the corresponding water tank 1 will be opened. When the water supply solenoid valves 9 on multiple water tanks 1 are all opened, the water tanks 1 with the water supply solenoid valves 9 open are connected in parallel. That is, at this time, the reagent in the parallel water tanks 1 is drawn at the same time through the liquid inlet main pipe 3-1, and the water is drained into the parallel water tanks 1 at the same time through the liquid outlet main pipe 3-3. At this time, the connecting valve 11 is opened to connect the pipes between the parallel water tanks 1, thereby realizing the connection between the parallel water tanks 1 to keep the water level of the water tanks 1 level.

[0059] The internal circulating water pump 6 draws reagents from the water tank 1 through the water distributor 4-1 and circulates them between the heat dissipation pipes 2. When the circulating solenoid valve 8 on the circulating inlet pipe 4-2 and circulating outlet pipe 4-3 of a set is closed, there is no water circulation in the corresponding heat dissipation pipe 2. Conversely, when the circulating solenoid valve 8 is opened, there is water circulation in the heat dissipation pipe 2. When the three-way solenoid valve 10 on both sides of the guide pipe 7 is opened to close the guide pipe 7, the heat dissipation pipes 2 are connected in parallel. When the three-way solenoid valve 10 is opened to open the guide pipe 7, the heat dissipation pipes 2 are connected in series. When the heat dissipation pipes 2 are connected in series, the circulating outlet pipe 4-3 on one heat dissipation pipe 2 sends circulating water into the circulating inlet pipe 4-2 of the adjacent heat dissipation pipe 2 through the guide pipe 7, and so on.

[0060] The technical advantages achieved by adopting the above technical solution are as follows:

[0061] 1. This device sets up a water tank 1 and a heat dissipation pipe 2 in parallel, and connects the water tank 1 and the heat dissipation pipe 2 through an internal circulating water pump 6, so as to draw reagents from the water tank 1 and send them into the heat dissipation pipe 2, and then carry away the heat generated by the diesel engine when it is working through the flow of reagents in the heat dissipation pipe 2.

[0062] 2. This device connects the heat dissipation pipe 2 to the water distributor 4-1 by setting a water distributor 4-1 between the internal circulating water pump 6 and the heat dissipation pipe 2, and sets a circulating water inlet pipe 4-2 and a circulating water outlet pipe 4-3. Furthermore, a guide pipe 7 is set between the circulating water inlet pipe 4-2 and the circulating water outlet pipe 4-3 by setting a three-way solenoid valve 10. This allows the heat dissipation pipe 2 to be connected in parallel or in series by changing the state of the three-way solenoid valve 10.

[0063] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
