DETAILED DESCRIPTION

[0015] The present invention can be implemented in many forms. Figure 1 An embodiment of a hybrid heat transfer assembly 10 for heavy equipment is shown in FIG. For convenience, the terms "upper", "lower", "top", and "bottom" are used herein to distinguish the upper and lower ends of the hybrid heat transfer assembly 10 and specific components of the assembly. It should be understood that "upper", "lower", "top", and "bottom" are only used for ease of description and understanding, and the above terms are not intended to limit the possible spatial orientation of the cooling assembly or its components during assembly or use.

[0016] The term "substantially" as used herein means mostly or nearly the same within the constraints of reasonable commercial engineering goals, costs, manufacturing tolerances, and capabilities in the art of heavy equipment thermal management component manufacturing and use. Similarly, the term "approximately" as used herein means close to or about a particular value within the constraints of reasonable commercial engineering goals, costs, manufacturing tolerances, and capabilities in the art of heavy equipment thermal management manufacturing and use.

[0017] The hybrid heat transfer assembly 10 can be configured to provide cooling for an operating device 12 of a piece of heavy equipment. The operating device 12 can take a variety of forms. For example, the operating device 12 can be an internal combustion engine, a battery, or a fuel cell used to power a piece of heavy equipment, such as a large mining hauler, a generator, an excavator, or any other type of mobile or stationary equipment. Other types of operating devices will become apparent to those skilled in the art given the benefit of this disclosure.

[0018] The hybrid heat transfer assembly 10 may include a coolant loop 14 configured to extract heat generated by the operating device 12. The coolant loop 14 may include one or more pipes 15 that may carry a coolant, such as a liquid, throughout the hybrid heat transfer assembly 10. The pipes 15 may be rubber hoses, metal pipes, or any conduit suitable for carrying heated coolant throughout the hybrid heat transfer assembly 10. Suitable forms for the pipes 15 will become apparent to those skilled in the art given the benefit of this disclosure.

[0019] The coolant passing through the coolant loop 14 can be heated by the operating equipment 12, then cooled by the components of the hybrid heat transfer assembly 10, and then returned to the operating equipment 12 to absorb heat again. In certain embodiments, the coolant in the coolant loop 14 can be water, or a mixture of water and antifreeze, deionized water, or a dielectric coolant. Other suitable coolants for the coolant loop 14 will become apparent to those skilled in the art given the benefit of this disclosure.

[0020] The coolant loop 14 may include a cooling fluid outlet 16 that directs coolant from the operating device 12 to the components to be cooled of the hybrid heat transfer assembly 10. The coolant loop 14 may also include a cooling fluid inlet 18 that directs coolant cooled by the components of the hybrid heat transfer assembly 10 back into the operating device 12.

[0021] The radiator 20 may include a radiator inlet 22 connected to the cooling fluid outlet 16 of the operating device 12 by the conduit 15 of the coolant loop 14. The radiator 20 may also include a radiator outlet 24. The coolant flowing out through the cooling fluid outlet 16 of the operating device 12 may then pass through the radiator 20, which may cool the heated coolant. A radiator fan 26 may be located proximate to the radiator 20 and may direct air through the radiator 20 to cool the heated coolant passing through the radiator 20 in a known manner. The radiator 20 may be a fin and tube radiator, a rod and plate radiator, or a removable tube radiator. Other suitable radiator types will become apparent to those skilled in the art given the benefit of this disclosure.

[0022] The hybrid heat transfer assembly 10 may also include a refrigerant cooling assembly 28 or chiller, which may be used to provide additional cooling to the coolant loop 14. The chiller 28 may include a refrigerant loop 30 configured to extract heat generated by operating the equipment 12. The refrigerant loop 30 may include one or more pipes 32 that may carry refrigerant throughout the chiller 28. The refrigerant passing through the refrigerant loop 30 may be R-134A, R-410A, or R-513A. Other suitable refrigerants will become apparent to those skilled in the art given the benefit of this disclosure.

[0023] The conduit 32 may be a rubber hose, a metal pipe, or any type of conduit suitable for carrying refrigerant throughout the chiller 28. Other suitable forms for the conduit 32 will become apparent to those skilled in the art, given the benefit of this disclosure.

[0024] The chiller 28 may include a compressor 34 that may act as a pump to compress the refrigerant gas, thereby creating a pressure differential that can drive the refrigerant to continuously circulate around the refrigerant circuit 30. The compressed refrigerant exiting the compressor 34 can then pass through a conduit 32 to a condenser 36, which can cool and condense the refrigerant gas into a liquid. A condenser fan 37 may be located near the condenser 36 and may direct air across the condenser 36 to cool the heated refrigerant passing through the condenser 36 in a known manner.

[0025] In the illustrated embodiment, a radiator fan 26 and a separate condenser fan 37 are shown. It should be understood that in some embodiments, a single fan may be configured to direct air through both the radiator 20 and the condenser 36. In other embodiments, more than one fan may be configured to direct air through either the radiator 20 or the condenser 36, or through both the radiator 20 and the condenser 36.

[0026] The liquid may then flow from the condenser 36 through the conduit 32 to the expansion valve 38 where the pressure of the liquid refrigerant is relieved, thereby allowing the refrigerant to expand into a lower pressure liquid or saturated mixture.

[0027] The lower pressure refrigerant can then flow through conduit 32 to evaporator 40, which may have an evaporator inlet 42 and an evaporator outlet 44. Coolant exiting from radiator 20 through radiator outlet 24 may flow through conduit 15 of coolant circuit 14 into and out of evaporator 40 through evaporator inlet 42 and evaporator outlet 44, respectively.

[0028] The evaporator 40 is used to absorb heat from the coolant, so that the refrigerant passing through the evaporator 40 is heated and evaporated. Subsequently, the superheated gas goes to the compressor 34 through the pipe 32, and then the process in the refrigerant circuit 30 is repeated. Therefore, the evaporator 40 acts as a heat exchanger to absorb heat from the coolant and transfer the heat to the refrigerant.

[0029] In such an embodiment, the radiator 20 and the evaporator 40 are connected in series so that the coolant absorbing heat from the operating equipment 12 may first be cooled by the radiator 20 and then additional cooling may be provided by the chiller 28. This may be advantageous because the radiator 20 may require less power to operate than the chiller 28, which may increase the efficiency and reduce the cost of operating the heavy equipment 12.

[0030] In certain embodiments, a temperature sensor 46 may be positioned in the coolant loop 14 to monitor the temperature of the coolant. In the illustrated embodiment, the temperature sensor 46 is positioned downstream of the evaporator 40 and upstream of the operating device 12. In certain embodiments, the temperature sensor 46 may be a thermostat, a thermocouple, or a resistance temperature detector ("RTD"). The temperature sensor 46 may send a signal to a controller 48 operatively connected to the compressor 34 via wiring 47. The controller 48 may be configured to send a signal via wiring 47 to control the operation of the compressor 34. The controller 48 may also be configured to control the operation of the radiator fan 26 and the condenser fan 37.

[0031] In certain embodiments, the controller 48 may be configured to simply turn on and off any one of the compressor 34, the radiator fan 26, and the condenser fan 37. In other embodiments, the controller 48 may be configured to provide variable speed control of any one of the compressor 34, the radiator fan 26, and the condenser fan 37, thereby providing more control over the cooling capacity of the chiller 28. In certain embodiments, the controller 48 may utilize a variable frequency drive (“VFD”) to control one or more of the radiator fan 26, the condenser fan 37, and the compressor 34 to save power.

[0032] In certain embodiments, the temperature sensor 46 may be positioned in the coolant loop 14, downstream of the radiator outlet 24 and upstream of the evaporator inlet 42. It should be appreciated that in other embodiments, the temperature sensor 46 may be positioned at other locations within the coolant loop 14. In certain embodiments, the temperature sensor 46 may be positioned directly on a portion of the heavy equipment, such as a battery or fuel cell, to directly monitor the temperature of these devices. Other suitable locations for the temperature sensor 46 will become apparent to those skilled in the art given the benefit of this disclosure.

[0033] Controller 48 may be a programmable logic controller ("PLC"), a controller area network ("CAN") bus, or any other type of computer, such as a personal computer, suitable for controlling the operation of chiller 28. Other types of controllers will become apparent to those skilled in the art given the benefit of this disclosure.

[0034] In some embodiments, when the coolant reaches a sufficiently low temperature, the controller 48 can operate in a known manner to close a solenoid valve (not shown) in the refrigerant circuit. This in turn may cause all of the refrigerant to be pumped into the condenser 36. Pumping refrigerant into the condenser 36 will reduce the pressure in the refrigerant circuit 30, which may trigger a low pressure switch (not shown) near the evaporator 40, which in turn will cut off power to the compressor 34. When the coolant temperature subsequently rises above a predetermined level, the controller 48 can operate to open the solenoid valve, restore pressure in the refrigerant circuit, and restart the compressor 34.

[0035] Figure 2 Another embodiment of the hybrid heat transfer assembly 10 is shown in FIG. In this embodiment, the radiator 20 and the evaporator 40 are connected in parallel. In this embodiment, the cooling for operating the device 12 can be provided by only the radiator 20, only the cooler 28, or both the radiator 20 and the cooler 28.

[0036] In this embodiment, the radiator outlet 24 is connected via the conduit 15 directly to the cooling fluid inlet 18 of the operating device 12. The evaporator inlet 42 is connected via the conduit 15 directly to the cooling fluid outlet 16 of the operating device 12.

[0037] The radiator flow valve 50 may be positioned in the conduit 15 near the radiator 20 to control the flow of coolant through the radiator 20. As shown, the radiator flow valve 50 may be positioned upstream of the radiator inlet 22. In other embodiments, the radiator flow valve 50 may be positioned downstream of the radiator outlet 24.

[0038] Similarly, an evaporator flow valve 52 may be positioned in the conduit 15 to control the flow of coolant through the evaporator 40. As shown, the evaporator flow valve 52 may be positioned upstream of the evaporator inlet 42. In other embodiments, the evaporator flow valve 52 may be positioned downstream of the evaporator outlet 44.

[0039] The controller 48 can be operably connected to each of the radiator flow valve 50 and the evaporator flow valve 52 to respectively control the flow of coolant through the radiator 20 and the evaporator 40. Thus, the controller 48 can allow coolant leaving the operating device 12 to flow only through the radiator 20, only through the evaporator 40, or through both the radiator 20 and the evaporator 40.

[0040] It should be noted that in some embodiments, the hybrid heat transfer assembly 10 may include one or more additional coolers to provide additional cooling capacity and / or redundancy for the hybrid heat transfer assembly 10. Each additional cooler may include a refrigerant circuit with pipes, a compressor, a condenser, a condenser fan, an expansion valve, and an evaporator. It should be noted that the evaporator of each additional cooler may be positioned in series or in parallel with the radiator 20 and the evaporator 40.

[0041] Figure 3 1 shows another embodiment of the hybrid heat transfer assembly 10. In this embodiment, a heater 56 can be connected to the coolant loop 14 to heat the coolant. The heater 56 can have a heater inlet 58 and a heater outlet 60. The coolant leaving the evaporator 40 through the evaporator outlet 44 can pass through the conduit 15 of the coolant loop 14, flow into and out of the heater 56 through the heater inlet 58 and the heater outlet 60, respectively, and then enter the operating device 12 through the cooling fluid inlet 18.

[0042] In cold environments, when the ambient temperature is below the desired operating temperature of the operating device 12, the heater 56 can be operated to heat the coolant in the coolant loop 14. It should be understood that the heater 56 may only be needed until the operating device 12 warms up, at which time the heater 56 can be turned off. In this embodiment, the radiator 20, the evaporator 40, and the heater 56 are connected in series. The controller 48 can be connected to the heater 56 via the wiring 47 to control the operation of the heater 56, for example, including turning the heater 56 on and off.

[0043] In certain embodiments, heater 56 may be an electric heater. Other suitable heater types will become apparent to those skilled in the art, given the benefit of this disclosure.

[0044] Figure 4 Another embodiment of the hybrid heat transfer assembly 10 is shown in FIG. In this embodiment, the radiator 20, the evaporator 40 and the heater 56 are connected in parallel. In this embodiment, the heater outlet 60 is directly connected to the cooling fluid inlet 18 of the operating device 12 via the pipe 15. In this embodiment, any combination of the radiator 20, the cooler 28 and / or the heater 56 can be used to provide thermal control for the operating device 12.

[0045] A heater flow valve 62 may be positioned in the conduit 15 to control the flow of coolant through the heater 56. As shown, the heater flow valve 62 may be positioned upstream of the heater inlet 58. In other embodiments, the heater flow valve 62 may be positioned downstream of the heater outlet 60.

[0046] In such an embodiment, the controller 48 can be operably connected to each of the radiator flow valve 50, the evaporator flow valve 52, and the heater flow valve 62 to respectively control the flow of coolant through the radiator 20, the evaporator 40, and the heater 56. Thus, the controller 48 can allow coolant leaving the operating device 12 to flow through only the radiator 20, only the evaporator 40, only the heater 56, or any combination of the radiator 20, the evaporator 40, and the heater 56.
