Abstract
Description
- The present invention relates to a heat exchanger, particularly, the present invention relates to a hybrid multi-core heat exchanger.
- Generally, a vehicle may include several heat exchangers. For example, a conventional engine cooling system of a vehicle includes a radiator to facilitate cooling of an engine of the vehicle. Specifically, a coolant in form of glycol or water-glycol mixture is passed through the engine, from where the coolant absorbs heat and becomes hot. The hot coolant is then fed into an inlet tank of the radiator that is located preferably on top of the radiator, or along one side of the radiator, from the inlet tank the hot coolant is distributed across a radiator core through radiator tubes to another tank on an opposite side of the radiator. As the hot coolant passes through the radiator tubes to the opposite tank, the coolant transfers heat to tubes of the radiator core, the radiator tubes transfers the heat to fins that are lodged between each row of radiator tubes. The fins then releases heat to the ambient air that flows across the radiator core. Similarly, there are other heat exchangers used in a vehicle, such as for example, a condenser, an evaporator used in Heating Ventilation and Air-Conditioning system of the vehicle, a chiller for battery cooling and a Charged Air Cooler (CAC) for cooling compressed air delivered to a turbo-charged engine. The various heat-exchangers are disposed either alone or in series adjacent to each other to form a heat exchanger module. Generally, the adjacently disposed heat exchangers are connected by engagements elements such as for example, clips formed on respective tanks of the adjacent heat exchangers. In case of such heat exchanger module is formed by connecting the adjacent heat exchangers, each of the heat exchanger has independent headers or tube collectors and independent tanks. As such the heat exchanger module formed by connecting independent heat exchangers are bulkier and packaging thereof in limited space is difficult. Further, such heat exchanger modules involve more number of parts, as such more inventories are required to be maintained and higher inventory costs are involved. Furthermore, such heat exchanger modules involve more number of manufacturing steps for manufacturing and assembly thereof as tanks and the headers of the individual heat exchangers are manufactured separately, thereby causing the manufacturing and assembly of the heat exchanger modules complex and inconvenient. Few prior art suggest heat exchanger module with tanks corresponding to a first heat exchanger core and a second adjacent heat exchanger core formed in a single step molding process. However, none of the prior art provide solution for preventing direct or indirect heat exchange between respective heat exchange media flowing through the adjacent heat exchange cores.
- Accordingly, there is a need for a hybrid multi-core heat exchanger that configures multiple heat exchanger cores connected by common elements to impart compact configuration thereto and enable packaging thereof in limited available space. Furthermore, there is a need for a hybrid multi-core heat exchanger that involves fewer steps for manufacturing and assembly thereof as compared to conventional heat exchanger module formed by connecting adjacent independent cores. Furthermore there is a need for a hybrid heat exchanger with multiple cores that involves fewer parts and eliminates use of connecting elements such as clips, and as such involves comparatively lesser inventory and inventory costs. Still further, there is a hybrid heat exchanger with multiple cores that can handle different heat exchange media for heat exchange while still preventing direct or indirect heat exchange between heat exchange media flowing through the different cores or the common elements connecting the heat exchanger cores.
- An object of the present invention is to provide a hybrid heat exchanger that configures multiple heat exchanger cores and connected by common elements, thereby reducing size and imparting compact configuration to the hybrid heat exchanger.
- Another object of the present invention is to provide a hybrid heat exchanger with multiple cores that is compact in configuration and that can be conveniently packaged in a limited space.
- Still another object of the present invention is to provide a hybrid heat exchanger with multiple cores that involves fewer parts and eliminates use of connecting elements such as clips, as such involves comparatively lesser inventory and inventory costs.
- Yet another object of the present invention is to provide a hybrid heat exchanger with multiple cores that involves fewer steps for manufacturing and assembly thereof as compared to conventional heat exchanger module formed by connecting adjacent independent cores.
- Still another object of the present invention is to provide a hybrid heat exchanger with multiple cores that can handle different heat exchange media for heat exchange while still preventing direct or indirect heat exchange between heat exchange media flowing through the different cores.
