A cooling module is coupled to an engine system and a Rankine cycle waste heat recovery system. The cooling module includes a heat exchanger for cooling a fluid of the engine system and a condenser for cooling a working fluid of the Rankine cycle waste heat recovery system, both of which extend in a width direction of the cooling module and are porous to a flow of cooling air in a depth direction of the cooling module. The condenser includes a first tubular header that extends in a height direction of the cooling module. A working fluid transfer tube fluidly couples the first tubular header to the Rankine waste heat recovery cycle system. The working fluid transfer tube has a first portion extending in the depth direction and a second portion extending in the height direction, the second portion being adjacent to the first tubular header in the width direction.

A heat exchanger includes: a plurality of first heat transfer tubes, a plurality of second heat transfer tubes located on leeward side relative to the plurality of first heat transfer tubes, a first distribution unit connecting the first ends of the plurality of first heat transfer tubes and the third ends of the plurality of second heat transfer tubes. The first distribution unit includes a flow rate control unit configured to be capable of switching between a first state and a second state. In the first state, refrigerant flows in the plurality of first heat transfer tubes and the plurality of second heat transfer tubes. In the second state, in only the plurality of first heat transfer tubes, a flow rate of the refrigerant is smaller than a flow rate of the refrigerant in the first state.

A heat exchanger array includes a first row of heat exchangers, a second row of heat exchangers, and side curtains. The first row heat exchangers are spaced apart to define first gaps. The second row heat exchangers are spaced apart to define second gaps and are positioned downstream of and staggered from the first row heat exchangers such that the second row heat exchangers are aligned with the first gaps and the first row heat exchangers are aligned with the second gaps. Each side curtain is in close proximity to a first row heat exchanger and a second row heat exchanger. The side curtains define a neck region upstream of and aligned with each first row heat exchanger and each second row heat exchanger. Each neck region has a neck area that is less than a frontal area of the heat exchanger with which it is aligned.

Provided is a heat exchanger including a plurality of refrigerant flow paths each being a flow path into which refrigerant flows in a gas state and out of which the refrigerant flows in a liquid state, and including upstream-side flow paths allowing passage of the refrigerant in the gas state and a two-phase gas-liquid state, and at least one downstream-side flow path allowing passage of the refrigerant in the two-phase gas-liquid state and the liquid state. The heat exchanger further includes an upstream-side heat exchanger including the upstream-side flow paths, a downstream-side heat exchanger including the at least one downstream-side flow path, and at least one merger for merging the refrigerant flowing out of each of the upstream-side flow paths and causing the merged refrigerant to flow into the at least one downstream-side flow path. The upstream-side heat exchanger and the downstream-side heat exchanger are configured separately. The number of the downstream-side flow paths is smaller than the number of the upstream-side flow paths.

A heat exchanger includes a plurality of fins arranged in parallel, and a plurality of heat exchanger tubes penetrating the fins. The heat transfer tubes define a plurality of refrigerant passages through which refrigerant is passed inside the heat exchanger. Each of the refrigerant passages is formed as a single independent passage from the refrigerant inlet to the refrigerant outlet.

A cooling module for a vehicle includes: a high temperature radiator including first and second header tanks into which a coolant flows and from which it is exhausted, and a plurality of tubes and heat radiating fins respectively interconnecting the first and second header tanks; a low temperature radiator including third and fourth header tanks into which a coolant flows and from which it is exhausted, and a plurality of tubes and heat radiating fins respectively interconnecting the third and fourth header tanks; and a condenser disposed at a side surface of the high temperature and low temperature radiators corresponding to the second and fourth header tanks to be respectively connected to the second and fourth header tanks and condensing a refrigerant flowing therein through heat exchange with a coolant supplied from the second and fourth header tanks.

In a heat source-side unit according to the present invention, a temperature sensor is installed on an inter-column connecting part included in a plurality of inter-column connecting parts and located higher than an intermediate position in a vertical direction of a heat exchanger.

A cooling package for a vehicle, such as an agricultural tractor, having a heat exchanger with a fan providing air flow and a charge air cooler assembly that airflow is routed through multiple times in order to cool a compressed charge of air. As the temperature rise experienced by the cooling airflow is relatively minor compared to the initial temperature of the compressed charge of air, the airflow is initially routed through an outlet-side portion of the charge air cooler to cool the compressed charge of air towards the outlet side of the charge air cooler, and subsequently routed through an inlet-side portion of the charge air cooler to cool the compressed charge of air towards the inlet side of the charge air cooler.

A heat exchanger array includes a first row of heat exchangers, a second row of heat exchangers, and side curtains. The first row heat exchangers are spaced apart to define first gaps. The second row heat exchangers are spaced apart to define second gaps and are positioned downstream of and staggered from the first row heat exchangers such that the second row heat exchangers are aligned with the first gaps and the first row heat exchangers are aligned with the second gaps. Each side curtain is in close proximity to a first row heat exchanger and a second row heat exchanger. The side curtains define a neck region upstream of and aligned with each first row heat exchanger and each second row heat exchanger. Each neck region has a neck area that is less than a frontal area of the heat exchanger with which it is aligned.

A vehicle heat management system is provided. The system includes a radiator module having a battery radiator and an electric component radiator. A valve module has an inner space that is divided into a first chamber and a second chamber. Each chamber includes a first passage, a second passage, and a third passage. The first passage connects each chamber to a battery radiator, the second passage connects each chamber to a high-voltage battery core, and the third chamber connects each chamber to an electric component radiator and an electric component core. Each chamber includes therein a guide unit that selectively closes the first passage, the second passage, or the third passage depending on a rotation angle thereof. An actuator that is connected to the guide unit adjusts the rotation angle of the guide unit.
