A THERMOSTAT ASSEMBLY CONTINUOUSLY ADJUSTING FLOW AMOUNT OF THE COOLANT FLOWING TOWARD THE HEATER PORT
Technical Field
The invention relates a thermostat assembly which continuously adjusts the flow amount of the coolant that flows toward the heater port (inlet), for providing constant energy transfer to the cabin heating system for each engine condition.
Specifically, the present invention relates to a thermostat assembly which has both continuously open and conditionally open feeding channels for the heater port.
Prior Art
Thermostat assembly within engine cooling system provides proper cooling of the engine and its parts by determining the flow ratio between bypass circuitry and heat exchange circuity according to the actual temperature value of engine coolant. The change in the flow ratio between bypass circuitry and heat exchange circuity is possible with the change in the opening ratio between bypass inlet window and radiator inlet window or bypass outlet window and radiator outlet window. The change in the opening ratio is provided by the forward and backward motion of the valve structure guided by means of a thermo-actuator throughout thermostat interior space. The forward and backward motion of the valve structure is provided by the motion of the piston element of the thermo-actuator.
In the conventional one inlet-two outlet thermostat assemblies, the piston element moves forward or backward according to the temperature of the engine outlet coolant coming from inlet. When the temperature value of the coolant coming from engine outlet is below than a first threshold value, the actuator continues to be stay at fully closed position, consequently the valve structure too. At this fully closed position of the actuator, valve structure allows coolant flow from inlet to bypass outlet and prevents coolant flow from inlet to radiator outlet by closing upper valve seat via upper valve element.
When the piston starts to move forward as a result of the increase in the coolant temperature (exceeding the first threshold value), other portion of the actuator (actuator body) starts to move backward due to the piston seat that restricts the forward motion of the piston end. The backward motion of the actuator body causes the backward motion of the valve structure too thanks to the force applied on sleeve seat of valve structure by sleeve portion of the actuator. When the temperature value of the coolant coming from engine outlet is equal or above than a second threshold value, opening of the actuator reaches its maximum point (full backward motion), consequently opening of the valve structure too. At this fully open position of the actuator, valve structure allows coolant coming from inlet to flow toward radiator outlet and prevents coolant flow from inlet to bypass outlet by closing the lower valve seat via lower valve element. At this temperature values above than the second threshold, the coolant coming from engine outlet continues to flow from inlet to radiator outlet throughout heat exchange circuitry comprising engine channels, radiator channels, water pump and thermostat assembly.
In the conventional way, the cabin heating system is fed from the bypass outlet. This means that a part of the engine inlet coolant is directed towards the heater port. Since the bypass outlet is open during fully closed thermostat position and closed during fully open thermostat position, there is a conditional flow through the bypass outlet, consequently through the heater port. In the fully open thermostat position, here there is not any heat energy transferred towards the heater port due to that bypass outlet is closed by the lower valve element. Besides, here, even in the fully closed thermostat position (when the engine starts yet to operate), enough amount of heat energy is not transferred towards the heater port due to that the feeding is provided through on just one channel (conditionally open bypass outlet). Although the cabin heating system requires constant heat energy transfer as independent from changing engine conditions, there is an irregular heat energy transfer towards the heater port due to both the variable temperature value of the engine inlet coolant and feeding just via one channel.
The document US3907199A mentions a combination engine cooling and passenger compartment heating system for an automotive vehicle. The system permits selective apportionment of engine coolant between the radiator and the heater to regulate the heat to the automobile passenger compartment and to lower the coolant temperature whenever possible. However, here it is not mentioned about a thermostat assembly which adjusts the flow amount of the coolant that flows toward the heater port, for providing constant energy transfer to the heater port for each engine condition.
As a result, there is a require for a thermostat assembly which adjusts the flow amount of the coolant that flows toward the heater port, for providing constant energy transfer to the cabin heating system for each engine condition. Objectives and Short Description of the Invention

Detailed Description of the Invention
This invention relates to a thermostat assembly (10) which continuously adjusts the flow amount of the coolant that flows toward the heater port, for providing constant energy transfer to the cabin heating system for each engine condition.
In the conventional thermostat assemblies, the cabin heating system is fed from the bypass outlet. This means that a part of the engine inlet coolant is directed towards the heater port. Since the bypass outlet is open during fully closed thermostat position and closed during fully open thermostat position, there is a conditional flow through the bypass outlet, consequently through the heater port. This conditional flow prevents the same level of heat energy to be transferred each time towards the cabin heating system, although the system requires constant heat energy.
When the engine starts yet to operate, bypass outlet temperature is quite low. In that case, the cabin heating system requires higher flow amount to reach constant heat energy transfer. Present invention provides constant heat energy transfer towards the cabin heating system during all engine conditions by the help of an additional feeding channel that is continuously open. Thanks to the continuously open feeding channel, when the engine outlet (Eo) temperature is lower, the higher flow amount of coolant provided towards the cabin heating system allows same level of heat energy to be transferred towards the cabin heating system.
The present thermostat assembly (10) comprises an upper frame (11) including piston seat (11.1), radiator valve seat (11.2), radiator outlet (11.3) portions, a lower frame (12) including inlet (12.1) coming from engine outlet (Eo), bypass outlet (12.2), heater primary outlet (12.3) providing primary stream (S1), heater secondary outlet (12.4) providing secondary stream (S2), bypass valve seat (12.5), heater valve seat (12.6), spring seat (12.7) portions, an upper valve structure (15) including radiator valve element (15.1) portion that seats onto mentioned radiator valve seat (11.2) during the fully closed thermostat position and sleeve seat (15.2) portion, a thermo-actuator (20) including sleeve (21) portion that is located onto mentioned sleeve seat (15.2), piston (22) portion that is located within mentioned piston seat (11.1), heat sensitive reservoir (23) portion that is located within interior space of said upper valve structure (15), a lower valve structure (16) including bypass valve element (16.1) portion that seats onto mentioned bypass valve seat (12.5) and heater valve element (16.2) that seats onto mentioned heater valve seat (12.6) during the fully open thermostat position, a first spring element (13) which is located between mentioned upper valve structure (15) and lower valve structure (16), a second spring element (14) which is located between said lower valve structure (16) and spring seat (12.7).
A front sectional view of the present thermostat assembly (10) in the fully closed thermostat position is given in Figure 1a. Present thermostat assembly (10) provides stream through both the heater primary outlet (12.3) and heater secondary outlet (12.4) in the fully closed thermostat position. As seen from Figure 1b, there are both the primary stream (S1) and the secondary stream (S2). Here, sum of primary stream (S1) and secondary stream (S2) forms the heater inlet (Hi) coolant. This means that higher amount of the bypass outlet coolant is send towards the cabin heating system when the engine starts yet to operate. Therefore, it becomes possible that sufficient heat energy is transferred towards the cabin heating system although the engine coolant is not warm enough.
A front sectional view of the present thermostat assembly (10) in the fully open thermostat position is given in Figure 2a. As seen from the Figure 2b, in the fully open thermostat position, since the heater primary outlet (12.3) is closed by the heater valve element (16.2), the primary stream (S1) is blocked. Here, there is just the secondary stream (S2) that flows through the heater secondary outlet (12.4) in the fully open thermostat position, and, the secondary stream (S2) forms the heater inlet (Hi) coolant. This means that less amount of the bypass outlet coolant is send towards the cabin heating system when the engine is warm. Consequently, it becomes possible that sufficient heat energy is transferred towards the cabin heating system since the engine coolant is hot. Briefly, present thermostat assembly (10) has two separate channels for feeding the cabin heating system. The first feeding channel corresponding to the heater primary outlet (12.3) provides primary stream (S1). This primary stream (S1) is a conditional stream since it is blocked during fully open thermostat position (hot state of the engine). The second feeding channel corresponding to the heater secondary outlet (12.4) provides secondary stream (S2). This secondary stream (S2) is a continuous stream since it continues to flow during both fully open, partially open, fully closed thermostat positions (respectively hot, warm and cold states of the engine).
The cabin heating system is fed by two separate channels (heater primary outlet (12.3) and heater secondary outlet (12.4)) during cold state of the engine. So, it becomes possible that sufficient amount of heat energy is transferred towards the cabin heating system by sending higher amount of coolant. During the hot state of the engine, the cabin heating system is fed just by one channel (heater secondary outlet (12.4)). So, it becomes possible to transfer sufficient amount of heat energy towards the cabin heating system by sending less amount of coolant. Present invention allows adjustment of the volume of the coolant that is sent to the cabin heating system for transferring constant level of heat energy independently from the engine conditions.
With this invention, the cabin heating system is integrated to the natural opening and closing function of the thermostat assembly (10).
The radiator valve element (15.1) prevents the engine outlet (Eo) coolant to pass towards the radiator channels during fully closed thermostat position by seating onto the radiator valve seat (11.2). Heater valve element (16.2) prevents back flows from the bypass outlet (12.2) during fully open thermostat position by seating onto heater valve seat (12.6). The first spring element (13) located between the upper valve structure (15) and the lower valve structure (16) provides flexible connection between these valve structures by preventing full contact between them. So, the distance between these valve structures can be changed. Also, as a require of construction, lower valve structure (16) has two sealing elements while upper valve structure (15) has just one sealing element. Besides, bypass valve element (16.1) is greater than the heater valve element (16.2). This difference in their size can be seen easily from Figure 3b.
