Description

Technical Field

[0001] This utility model relates to the field of engine oil tank technology, and in particular to a self-controlled temperature float oil tank. Background Technology

[0002] A float-type fuel tank is a fuel tank equipped with a float. The float is used to detect the fuel level. It is a type of fuel tank that opens the fuel inlet when the fuel level is low and closes the fuel inlet when the fuel level is high, so that the fuel level in the tank is always kept within a specified range.

[0003] Traditional float-type fuel tanks can only solve the problem of high return oil inlet temperature, but cannot solve the problem of excessively high or low outlet oil temperature. Excessively high outlet oil temperature will affect the engine's power output, thus impacting normal operation, while excessively low outlet oil temperature will affect the machine's cold start capability.

[0004] Therefore, existing float-type fuel tanks need to be optimized to adjust the fuel outlet temperature. However, the traditional method involves adding a fan and cooling core near the fuel outlet of the float-type fuel tank for air cooling, which has low cooling efficiency. For example, utility model patent CN220151458U discloses an existing float-type fuel tank with air cooling. When rapidly cooling the fuel outlet temperature, the air cooling method cannot quickly lower the temperature in a short time. The heat exchange efficiency based on forced air convection is difficult to match the transient heat load of the fuel system. The auxiliary cooling system consumes power that accounts for a significant portion of the engine's total output power, significantly affecting the overall engine efficiency ratio and making it impossible to adjust the engine's power output in a timely manner, thus impacting the user experience. Utility Model Content

[0005] In view of this, the technical problem to be solved by this utility model is to provide a self-controlled temperature float oil tank that can change the original cooling method, improve cooling efficiency, reduce engine output loss, adjust engine power output in a timely manner, and improve the user experience.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A self-controlled temperature float oil tank includes a tank body, an oil inlet at the top of the tank body, an oil outlet at the bottom of the tank body, a heater, a temperature sensor, and a cooling core installed inside the tank body, the heater and the cooling core being horizontally positioned above the oil outlet, and the temperature sensor being positioned close to the oil outlet.

[0008] The cooling core includes several cooling pipes and several clamping plates, all of which are vertically spaced. The cooling pipes pass horizontally through the clamping plates and their two ends are connected to the housing. The two side walls of the housing are respectively equipped with water inlets and water outlets that communicate with the inside of the cooling pipes. The water inlets are connected to the water pump.

[0009] Preferably, the card plate includes a plurality of main card plates and a plurality of sub-card plates, the plurality of sub-card plates being spaced apart, and the main card plate being disposed between two adjacent sub-card plates.

[0010] Preferably, the main card plate has a circular structure, and the secondary card plate has a semi-circular structure.

[0011] Preferably, a plurality of the cooling pipes are equidistantly arranged on the main card plate along the circumference of the main card plate.

[0012] Preferably, the two side walls of the housing are equipped with an inlet water distribution chamber and an outlet water collection chamber. The inlet water distribution chamber is connected between the water inlet and one end of the cooling pipe, and the outlet water collection chamber is connected between the water outlet and the other end of the cooling pipe.

[0013] Preferably, both the inlet water distribution chamber and the outlet water collection chamber have a funnel-shaped structure, and the large-diameter ends of both the inlet water distribution chamber and the outlet water collection chamber are located close to the housing.

[0014] Preferably, the top of the housing is provided with a vent and an oil return port.

[0015] Preferably, it also includes a controller, which is electrically connected to the heater and the temperature sensor respectively.

[0016] Preferably, an electromagnetic water valve is provided between the water inlet and the water pump, and the electromagnetic water valve is electrically connected to the controller.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] The self-controlled temperature float fuel tank of this application includes a tank body with an inlet at the top and an outlet at the bottom. Inside the tank are a heater, a temperature sensor, and a cooling core. Both the heater and cooling core are horizontally positioned above the outlet, and the temperature sensor is located close to the outlet. When the temperature sensor detects that the fuel temperature inside the tank, especially the outlet temperature, is higher than a set value, external cooling water, such as seawater, enters the cooling core to cool the fuel. When the outlet temperature is lower than the set value, external cooling water stops entering the cooling core, and the heater turns on to heat the fuel. By using the heater and cooling core in conjunction, the fuel temperature inside the tank is controllable, keeping the outlet temperature within the set range. This allows for timely adjustment of engine power output, improving user experience. Furthermore, it replaces the traditional air-cooling method, improving cooling efficiency, quickly matching transient heat loads of the fuel system, and does not consume total engine output power, thus reducing output loss.

[0019] In this application, the cooling core includes several cooling pipes and several clamping plates, all of which are vertically spaced. The cooling pipes pass horizontally through the clamping plates, and their two ends are connected to the housing. Inlet and outlet water ports, communicating with the interior of the cooling pipes, are installed on the side walls of the housing, respectively. The inlet water port is connected to a water pump. Cooling water flows through the cooling pipes. To prevent deformation of the cooling pipes from affecting their flow and to prevent impacting their service life, clamping plates are installed on the outside of the cooling pipes to enhance the connection strength along their length and extend their service life. Furthermore, these clamping plates are not connected to the inner wall of the housing, reducing construction complexity and facilitating installation. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 1 to 3 As shown in the figure, the present invention includes a housing 1, an oil inlet 2 is provided at the top of the housing 1, an oil outlet 3 is provided at the bottom of the housing 1, and a heater 4, a temperature sensor 5 and a cooling core 6 are installed inside the housing 1. The heater 4 and the cooling core 6 are both horizontally arranged above the oil outlet 3, and the temperature sensor 5 is arranged close to the oil outlet 3.

[0031] When the temperature sensor 5 detects that the fuel temperature inside the fuel tank 1, especially the fuel outlet temperature at the outlet 3, is higher than the set value, external cooling water, such as seawater, enters the cooling core 6 to cool the fuel inside the fuel tank 1. When the fuel outlet temperature is lower than the set value, the external cooling water stops entering the cooling core 6, and the heater 4 turns on to heat the fuel inside the fuel tank 1. By using the heater 4 and the cooling core 6 in cooperation, the fuel temperature inside the fuel tank 1 can be controlled, keeping the fuel outlet temperature within the set range. This allows for timely adjustment of engine power output, improving user experience. Moreover, it replaces the traditional air-cooling method, improving cooling efficiency, quickly matching the transient thermal load of the fuel system, and does not occupy the engine's total output power, reducing output loss.

[0032] The cooling core 6 includes several cooling pipes 61 and several clamping plates 62. The clamping plates 62 are all vertically spaced. After the cooling pipes 61 pass horizontally through the clamping plates 62, their two ends are connected to the housing 1. The two side walls of the housing 1 are respectively equipped with water inlets 63 and water outlets 64 that communicate with the inside of the cooling pipes 61. The water inlets 63 are connected to the water pump (not shown in the figure).

[0033] This application applies to marine engines. In this application, the water pump is a seawater pump of the marine engine, which pumps external seawater as cooling water for cooling. No other equipment is required. The cooling water flows in the cooling pipe 61. In order to prevent the cooling pipe 61 from deforming due to long-term use and affecting its flow, and in order to prevent the cooling pipe 61 from affecting its service life, a clamping plate 62 is installed on the outside of the cooling pipe 61 to enhance the connection strength in the length direction of the cooling pipe 61 and extend its service life. Moreover, it is not connected to the inner wall of the housing 1, which reduces the construction complexity and facilitates construction and installation.

[0034] Preferably, one end of the cooling core 6 is fixedly connected to the inner wall of the housing 1 by multiple bolts, while the other end is fitted with a fixing sleeve on the housing 1, with the other end of the cooling core 6 inserted into the fixing sleeve. Of course, a sealing structure (such as a sealing ring) is also provided between the cooling core 6 and the fixing sleeve to seal the connection point. The specific structure of this structure is well-known in this technical field and will not be described in detail here. Alternatively, both ends of the cooling core 6 can be detachably connected to the housing 1 by bolts, rather than by welding, thus facilitating disassembly and maintenance.

[0035] In this application, the card plate 62 includes a plurality of main card plates 621 and a plurality of auxiliary card plates 622. The auxiliary card plates 622 are spaced apart, and the main card plates 621 are disposed between two adjacent auxiliary card plates 622. The number of main card plates 621 and auxiliary card plates 622 is determined based on the length of the cooling core 6. Preferably, there are two main card plates 621, symmetrically arranged along the center of the cooling core 6; and three auxiliary card plates 622, one of which is disposed at the center of the cooling core 6 to enhance the strength of the center of the cooling core 6.

[0036] The main card plate 621 has a circular structure, and the secondary card plate 622 has a semi-circular structure. Several cooling pipes 61 are equidistantly arranged on the main card plate 621 along its circumference.

[0037] In this application, inlet diversion chambers 65 and outlet manifolds 66 are installed on both side walls of the housing 1. The inlet diversion chambers 65 connect the inlet 63 to one end of the cooling pipe 61, and the outlet manifolds 66 connect the outlet 64 to the other end of the cooling pipe 61. Because the inner diameter of the inlet 63 is smaller than the inner diameter of the cooling core 6, the seawater entering through the inlet 63 needs to be diverted through the inlet diversion chambers 65 so that it can pass through all the cooling pipes 61. Similarly, the seawater discharged through the cooling pipes 61 also needs to be collected through the outlet manifolds 66 before being discharged through the outlet 64.

[0038] Preferably, both the inlet water diversion chamber 65 and the outlet water confluence chamber 66 are funnel-shaped structures, and the large-diameter ends of both the inlet water diversion chamber 65 and the outlet water confluence chamber 66 are located close to the housing 1.

[0039] The top of the housing 1 is provided with a vent 7 and an oil return port 8. Ventilation and oil return are accomplished through the vent 7 and the oil return port 8, respectively.

[0040] This application also includes a controller, which is electrically connected to the heater 4 and the temperature sensor 5 respectively. An electromagnetic water valve is installed between the water inlet 63 and the water pump. The temperature sensor 5 is used to detect the fuel temperature inside the tank 1. When the detected temperature is lower than the set value, the controller controls the heater 4 to turn on to heat up. At this time, the electromagnetic water valve and the water pump are both closed, and no seawater enters the cooling pipe 61. When the detected temperature is higher than the set value, the controller controls the electromagnetic water valve and the water pump to turn on to pump seawater. At this time, the heater 4 is closed, thereby cooling the fuel inside the tank 1.

[0041] Specifically, in use, the user sets the outlet temperature limit on the controller according to the engine's inlet oil temperature requirements. Let's assume the upper limit is N and the lower limit is P. The temperature sensor detects the outlet temperature as X. When the outlet temperature X < P, the controller controls heater 4 to heat the fuel. When the outlet temperature P < X < N, no action is taken. When X > N, the controller controls the solenoid water valve to open and cool the fuel. The larger the value of XN = Y, the larger the water valve opening, thus keeping the outlet temperature within the set range.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
