The present disclosure provides a drain valve for a heat exchanger. The drain valve includes a plug body and a locking member. The plug body extends in an axial direction and is configured to be inserted into a discharge port of the heat exchanger. The locking member is spaced away from the plug body in a radial direction of the plug body. The locking member is configured to engage with the discharge port when the plug body is inserted into the discharge port.

A heat exchanger includes tubes having tube inlets, an inlet tank having therein an inlet tank space, and a dynamic baffle disposed in the inlet tank space. The inlet tank has a tank inlet. The tubes include first tubes and second tubes. The first tubes are closer to the tank inlet than the second tubes are to the tank inlet. The first tubes include a nearest tube that is, among the tubes, closest to the tank inlet. The dynamic baffle is configured to, when the fluid pressure of the thermal fluid in the inlet tank space is below a specified value, suppress the flow rates of the plurality of first tubes, and, when the fluid pressure of the thermal fluid in the inlet tank space is at or above the specified value, increase the flow rate of at least one of the plurality of the first tubes.

A heat treatment module for a heat treatment system of a vehicle is disclosed. The heat treatment module includes a first heat exchanger, a second heater, and an internal heat exchanger. The first heat exchanger and the second heat exchanger both are configured to create an exchange of heat between a refrigerant and a heat transfer liquid. The internal heat exchanger is configured to create an exchange of heat within the refrigerant, which in heat treatment system is subjected to two different temperature levels. The heat treatment module includes an expansion member that is at least secured to the first heat exchanger and/or the second heat exchanger.

Provided is a heater core which has a simple structure using a pipe connector formed by coupling a first plate and a second plate, thereby facilely manufacturing it, and also which can have a smaller size, since an inlet pipe and an outlet pipe are disposed to be adjacent to each other.

A heat exchanger arrangement, especially for a vehicle heater, includes a pot-like heat exchanger housing (12) extending in the direction of a longitudinal axis (L) of the housing. The heat exchanger housing includes an outer housing part (14) with the outer circumferential wall (18) and with an outer bottom wall (20) as well as an inner housing part (16) with the inner circumferential wall (22) and with an inner bottom wall (24). A heat carrier medium flow connecting piece (50, 52), open towards the heat carrier medium flow space, is provided at an axial end area (44) of the outer circumferential wall of the outer housing part, the end area being located at a distance from the outer bottom wall. A waste gas flow connecting piece (30) is open towards an interior space (26) of the heat exchanger housing, which interior space is enclosed by the inner wall.

An air conditioning system having a compact configuration may include an evaporator and a heater core that have a cylindrical shape. The evaporator defines a cavity. The heater core is positioned within the cavity such that the evaporator and the heater core are coaxially positioned with each other about a center axis. The heater core is configured to rotate about the center axis to draw in air.

A heat exchanger includes tubes arranged side by side, and a tank connected to ends of the tubes. The heat exchanger performs heat exchange between a first fluid flowing inside the tubes and a second fluid flowing outside the tubes. The heat exchanger includes a closing member disposed inside the tank and partially closing an opening provided at an end of a predetermined tube that is at least one of the tubes. The predetermined tube has a protrusion formed at the end of the predetermined tube. The closing member has an avoiding structure that avoids interference between the protrusion and the closing member.

An electric vehicle having a heat exchanger formed in an aerodynamic airfoil shape comprising one or more body panels disposed along an outer surface of the vehicle having one or more fluidic chambers or micro-channels. The heat exchanger is adapted to provide effective and highly efficient heat transfer, and also to provide substantially reduced or negligible contribution to the aerodynamic drag. The heat exchanger includes a supplemental heat exchange system wherein at least a portion of the heat exchange capacity is provided by an inner heat exchange surface of the heat exchanger exposed to an interstitial space within the vehicle. Airflow is forced, via a fan for example, from an aerodynamically-efficient inlet, over the inner heat exchange surface, and exhausted through an aerodynamically-efficient outlet, thereby providing a supplemental heat exchange system including substantially reduced or negligible contribution to the aerodynamic drag.

A heat exchange module having a first heat exchanger, configured to enable heat exchange between a first fluid and a flow of air and extending inside a first plane of overall extension, and a second heat exchanger, configured to enable heat exchange between a second fluid and the flow of air and extending inside a second plane of overall extension, is disclosed. A housing delimiting, with the first heat exchanger, a circulation channel for the flow of air is included. The module has at least one air distribution member, movable between a position in which the air distribution member allows the flow of air to pass through the first heat exchanger and the second heat exchanger, and a position in which the air distribution member prevents the flow of air from passing through the first heat exchanger while allowing the flow of air to pass through the second heat exchanger.
