FIG. 1
The present invention relates to radiators and in particular to a radiator for a vehicle with variable flow.
At present vehicles are used for various purposes such as transporting goods, traveling, for excavating etc. The internal combustion engines produce a lot of heat which has to be dissipated safely and in a reliable manner.
Generally, radiators are used in conjunction with the internal combustion engines, wherein the radiator includes a coolant which performs the function of extracting heat from the engine and dissipating it. Thus, radiators control engine temperature in cars, buses, SUV, a minivan, vans, trucks, etc., and maintains the temperature of the engine in permissible limit to have working of combustion cycle in any given scenario.
However, there are certain instances wherein the engine temperature increases beyond the permissible limits. One such example is when the vehicle is running in lower gears such as the first gear and the second gear. Another example is when the vehicle is running for a long time period without stop. In such and other instances, there is a possibility that the vehicle engine is overheated and the conventional radiators with the coolant flow therein is not sufficient to maintain the engine temperature within the desired permissible limits.
Thus, there is felt a need to provide a radiator and a system that is capable of maintaining the engine temperature within the desired permissible limits.
An object of the present invention is to provide a radiator which is capable of maintaining the engine temperature within the desired permissible limits in any circumstances; and
Another object of the present invention is to provide a radiator and a system which overcomes one or more drawbacks of the conventional radiators.
The present invention discloses a modified radiator system for extracting heat from an internal combustion engine, which comprises a radiator having a body. The body comprising radiator tube messing assembly, an inlet configured on an operative top-side of the body, the inlet configured for receiving coolant from a coolant reservoir; an inlet configured on an operative top of the body, the inlet configured to cover an inlet aperture configured on the operative top of the body, one or more mounting fixtures coupled to the body, the one or more mounting fixtures facilitating in mounting of the body, an outlet configured on an operative bottom-side of the body, the outlet configured for facilitating exit of heated coolant from the body back to the coolant reservoir, an outer body structure configured to hold and support the body, the inlet, the fixtures, and the outlet,
The system further includes an accumulator, an auxiliary coolant reservoir configured for storing the coolant therein and two-way bypass valve having a body, a main conduit having a first end and a second end, a side conduit extending from the first end of the main conduit and in fluid communication with the main conduit, a main inlet conduit extending from the side conduit configured to receive coolant from a coolant reservoir, and an auxiliary inlet conduit extending from the first end of the main conduit to receive additional coolant from a coolant accumulator; and a control valve being actuated by the controller when the temperature of the coolant is greater than a predetermined value so as to pump extra coolant from the auxiliary coolant reservoir in to the radiator, wherein the auxiliary coolant reservoir is connected to and in fluid communication with the auxiliary inlet conduit.
The system further includes a controller, a memory associated and cooperating with the controller, temperature sensor configured to measure the temperature of the heated coolant received from the radiator, a sensor for determining in which gear the vehicle is running, a gear indicator for displaying the gear of the vehicle, and a graphic display for displaying the temperature of the heated coolant.
FIG. 1 illustrates an isometric view of a radiator along with various parts thereof;
FIG. 2 illustrates a front view of the radiator of FIG. 1;
FIG. 3 illustrates an isometric view of an accumulator two-way bypass valve assembly; and
FIG. 4 illustrates an isometric view of an accumulator along with connections thereof.
The present invention relates to radiators and in particular to a radiator for a vehicle with variable flow.
The present invention is now described with reference to the accompanying drawings wherein FIG. 1 illustrates an isometric view of a radiator along with various parts thereof, FIG. 2 illustrates a front view of the radiator of FIG. 1, FIG. 3 illustrates an isometric view of an accumulator two-way bypass valve assembly, and FIG. 4 illustrates an isometric view of an accumulator along with connections thereof.
It is known in the art that the temperature hike in the radiator is directly proportional to increasing load on the engine in high torque and high-speed condition.
The radiator and the system accompanying the radiator of the present invention provides a compact heat exchanger that can serve the purpose of rapid heat exchange and to increase the horse power of the engine without overheating the flow lines.
In accordance with the present invention, a coolant fluid is pumped into the radiator and the engine assembly wherein the coolant travels through the conduits suitably configured in and around the engine, which then passes through the cylinder head of the engine. A thermostat or temperature sensor is disposed at a point where the coolant fluid leaves the engine.
After this the coolant fluid returns to the pump directly if the thermostat is not open. If it is open, the fluid goes through the radiator arrangement first and then back to the pump assembly. There is also a separate circuit for the heating system. This circuit takes the heated coolant fluid from the cylinder head and passes it through a heater core and then back to the pump.
In accordance with an embodiment of the present invention a modified radiator system (100) for extracting heat from an internal combustion engine is disclosed. The system (100) comprising a radiator (200) having a body (202) comprising radiator tube messing assembly (204), an inlet (206) configured on an operative top-side of the body (202), the inlet (206) configured for receiving coolant from a coolant reservoir, an inlet (208) configured on an operative top of the body (202), the inlet (208) configured to cover an inlet aperture configured on the operative top of the body (202), one or more mounting fixtures (210) coupled to the body (202), the one or more mounting fixtures (210) facilitating in mounting of the body (202), an outlet (212) configured on an operative bottom-side of the body (202), the outlet (212) configured for facilitating exit of heated coolant from the body (202) back to the coolant reservoir, an outer body structure (214) configured to hold and support the body (202), the inlet (206), the fixtures (210), and the outlet (212), an accumulator (300) having an auxiliary coolant reservoir (302) configured for storing the coolant therein.
