A heat exchanger assembly includes a frame, a plurality of tubes, and a first bumper clip attaching at least a first tube of the plurality of tubes to the frame. The first tube defines a first exterior dimension and the first bumper clip defines a first tube slot defining a first tube slot dimension that is less than the first exterior dimension of the at least first tube.

A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, and a water pump. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The secondary condenser receives the second airflow and outputs a dehumidified airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the primary condenser. The primary condenser receives the flow of refrigerant and outputs the flow of refrigerant at a lower temperature through heat transfer with a flow of fluid. The flow of fluid is directed, by the water pump, to a heat exchanger or an external source, where heat is rejected from the flow of fluid.

A laser cooling system includes a first tubing, a second tubing, and a cold plate assembly including a first channel to receive the first tubing and a second channel to receive the second tubing. A joint removably couples the first tubing to the second tubing and at least one component mounted on the cold plate assembly over the first tubing or the second tubing.

A cooling system for a motor vehicle may include a first circuit, a second circuit, a first heat exchanger incorporated in the first circuit, and a second heat exchanger incorporated in the second circuit. The first heat exchanger and the second heat exchanger may be flowed through by ambient air and a coolant. The first heat exchanger may be arranged, relative to an airflow direction, in front of and directly adjacent to the second heat exchanger. The first circuit and the second circuit may be fluidically connected to one another at an upstream distribution point and at a downstream collection point such that a part mass flow of the coolant is flowable from the second circuit into the first circuit at the distribution point, from the first circuit into the first heat exchanger, and out of the first heat exchanger back into the second circuit at the collection point.

An upstream heat exchange unit is disposed upstream of the airflow direction. An downstream heat exchange unit is disposed downstream of the upstream heat exchange unit. When the heat exchanger functions as an evaporator, a gas outlet pipe is an upstream refrigerant outlet that is located adjacent to the other end of upstream flat pipes of the upstream heat exchange unit, and a gas outlet pipe is a downstream refrigerant outlet that is located adjacent to the other end of downstream flat pipes of the downstream heat exchange unit. First resistance to refrigerant flow in the upstream heat exchange unit and second resistance to refrigerant flow in the downstream heat exchange unit are adjusted in order that the degree of superheating of refrigerant at the downstream refrigerant outlet is smaller than the degree of superheating of refrigerant at the upstream refrigerant outlet.

A heat exchanger for a refrigerator, which is of a microchannel type, includes a first heat exchange unit including a plurality of flat tubes, which serves to exchange heat between refrigerant and are connected to an introduction pipe, a second heat exchange unit including a plurality of flat tubes, which serve to exchange heat between the refrigerant and air and are disposed outside the first heat exchange unit so as to be connected to a discharge tube, and a connecting pipe connecting the first heat exchange unit to the second heat exchange unit to supply the refrigerant to the second heat exchange unit, wherein the first heat exchange unit is disposed so as to exchange heat with air, and wherein a total cross-sectional area of the flat tubes of the first heat exchange unit is larger than that of the flat tubes of the second heat exchange unit.

An air-conditioning unit includes an air-conditioning case and a heat exchanger. The heat exchanger includes a plurality of tubes and a header tank. The air-conditioning case includes a holder in which the header tank is held while being inserted therein. The holder includes a first rib and a plurality of second ribs for pressing a tank outer wall of the header tank toward an internal space of the header tank. The first rib extends in a tube stacking direction. The plurality of second ribs are each connected to the first rib, are formed to extend from the first rib away from the tubes, and are arranged side by side at a predetermined inter-rib spacing in the tube stacking direction. The inter-rib spacing is larger than a length of the second ribs extending from the first rib away from the tubes in a tube longitudinal direction.

Methods and systems are provided for a cooling module assembly for a vehicle. In one example, the cooling module assembly includes a first set of fins arranged in a circle, configured to flow a first fluid through a first sinusoidal, continuous inner passage, and a second set of fins, also arranged in a circle and configured to flow a second fluid through a second sinusoidal, continuous inner passage. The second set of fins shares a common plane with the first set of fins and is arranged concentric about the first set of fins.
