140 Heater Core
Daru Electric recommends for you
1. In the automotive field, the HVAC system regulates the aerodynamic thermal parameters of the air circulating in the passenger compartment. A heater core is a radiator-like device used to heat the cabin of a motor vehicle. Hot coolant from the motor vehicle's engine passes through the coiled tubes of the heater core, a heat exchanger between the coolant and the cabin air. Fins attached to the heater core tubes are used to increase the heat transfer surface, transferring heat to the air forced over the fins by a fan, thereby warming the cabin of the motor vehicle.
Technical Implementation Elements:
2. In general, in one aspect, embodiments disclosed herein relate to a method for servicing a heater core installed in an HVAC component of a motor vehicle. The method includes removing a sealing attachment from an interface connection that interfaces with the heater core. The method includes sliding the heater core in an insertion direction. The method includes disconnecting an interface connection pipe from the heater core. The method includes removing the heater core in a withdrawal direction. The withdrawal direction is orthogonal to the insertion direction.
3. In general, in one aspect, embodiments disclosed herein relate to an HVAC component for a motor vehicle. The HVAC component includes a heater core. The HVAC component includes a housing having walls defining an interior volume of the HVAC. The heater core is configured to slide inward in the interior volume toward an opposite side of the housing in an insertion direction. The HVAC component is configured for servicing the heater core by removing the heater core from the HVAC component in a withdrawal direction. The withdrawal direction is orthogonal to the insertion direction.
4. In general, in one aspect, embodiments disclosed herein relate to an HVAC system for a motor vehicle. The HVAC system includes a heater core. The HVAC system includes at least two pipe sleeves interfacing with the heater core, the at least two pipe sleeves conveying fluid to or from the heater core. The HVAC system includes at least two sealing attachments sealing at least two sealing points of the HVAC system. The heater core is configured to slide inward in the interior volume toward an opposite side of the housing in an insertion direction. The HVAC system is configured for servicing the heater core by removing the heater core from the HVAC component in a withdrawal direction. The withdrawal direction is orthogonal to the insertion direction.
5. The heater core may be serviceable with minimal HVAC module or dashboard disassembly. The heater core may also be serviceable from the cabin side of the motor vehicle. The heater core may also be serviceable in a vertical direction, while the heater core may be inserted into the distribution subassembly in a horizontal direction. To remove the heater core, it may not be necessary to pull the heater core horizontally out of the distribution subassembly, which would require horizontal space equivalent to the length of the heater core.
6. In one or more embodiments, the heater core may be configured for servicing in a manner that allows the HVAC module to be assembled in a lateral configuration (horizontal) while still allowing the heater core to be serviced vertically, thereby avoiding limited horizontal vehicle clearance. To this end, the heater core may be configured to move across the motor vehicle within the module when the support cover is removed. Locking ribs attached to the support cover may hold the core in place during normal use. Thus, when the support cover is removed, the heater core can be pushed across the motor vehicle, compressing a thick sheet of elastic material that prevents air from bypassing the heater core. In one or more embodiments, once the heater core is moved inward, tubes attached to the heater core can rotate out of tank sleeves attached to the heater core, thereby providing clearance for the heater core to slide vertically out of the module. Installation can be performed by reversing the process.
7. Other aspects of the present disclosure will become apparent from the following description and the appended claims.
