Heat exchanger with multiple heat exchange units and pipe groups
A recently granted patent (Publication Number: US11885512B2) discloses a unique heat exchanger design comprising two heat exchange units stacked vertically, each with a configuration of heat transfer pipe groups allowing for efficient refrigerant flow. The heat exchanger includes an intermediate header unit that facilitates the flow of refrigerant between the heat transfer pipe groups in a specific manner. When functioning as a condenser, the intermediate header unit ensures the proper direction of refrigerant flow through the heat transfer pipe groups, optimizing the heat exchange process.
Furthermore, the patent details additional components of the heat exchanger, such as headers, inlet and outlet pipes, and a communicating unit, all strategically placed to enhance the efficiency of the heat exchange process. The design allows for the heat exchanger to be divided into two parts, forming a negative-side and positive-side heat exchanger, connected in series. This configuration is particularly beneficial when the heat exchanger functions as a condenser, as it enables the flow of refrigerant between the two parts, with the positive-side heat exchanger being larger in capacity. The patent also specifies the angles at which each heat exchange unit is positioned relative to the flow direction of air, further optimizing the heat exchange process within the refrigeration cycle device incorporating this innovative heat exchanger design.
