As a result, high pressure resistant performance of the header box and the heat exchanger can be achieved.

Heat exchanger designs incorporating helixes and methods for making heat exchangers incorporating helixes are provided herein. In preferred embodiments, the heat exchanger comprises a plurality of fluid A channels each formed from a tube spiraled into a helix to form a plurality of helixes wherein the plurality of helixes are arranged in a hexagonal packing arrangement in a packing plane perpendicular to the axes of rotation of the plurality of helixes and wherein the pitch of each helix in the plurality of helixes is matched to an exterior diameter of the tube such that each helix in the plurality of helixes has a sealed interior that forms a plurality of fluid B channels.

An ice machine for an ice-based thermal storage system comprises a plurality of pillow plates arranged in a plate bank, wherein each of the plurality of pillow plates includes an inlet connection and an outlet connection, with the respective inlet connections connected to a feed header, and with the respective outlet connections connected to a suction header. A water distribution pan is positioned at a top of the plate bank, and a tank is positioned below the plate bank. As an evaporator, the ice machine causes ice to form on the pillow plates, which then falls into the tank. As a condenser, the ice machine transfers heat to water flowing over the pillow plates, such that water at an increased temperature falls into the tank and melts the ice in the tank.

An air conditioner includes a header for introducing refrigerant into a plurality of refrigerant tubes provided in parallel in a vertical direction. The header includes a main header chamber extending in the vertical direction and a plurality of sub header chambers branched in the horizontal direction from the main header chamber and provided in parallel in the vertical direction. The main header chamber includes a refrigerant inlet port configured to introduce the refrigerant in a gas-liquid mixing state in a horizontal direction into an inside of the main header chamber; and a flow direction changing mechanism provided to collide with the refrigerant ejected from the refrigerant inlet port, and configured to change a flow direction of the refrigerant from the horizontal direction to the vertical direction.

Disclosed is a combined core microchannel heat exchanger comprising a first plurality of microchannel tubes extended between, and in fluid communication with, a first inlet header and a first outlet header arranged in a first fluid circuit, a second plurality of microchannel tubes extended between, and in fluid communication with, a second inlet header and a second outlet header arranged in a second fluid circuit, wherein the first fluid circuit is fluidly isolated from the second fluid circuit and a microchannel tube of the second plurality of microchannel tubes is interleaved adjacent to microchannel tubes of the first plurality of microchannel tubes, and a plurality of fins disposed between the microchannel tube of the second plurality of microchannel tubes and the first plurality of microchannel tubes.
