The disclosed embodiments relate to a system that provides a polymer heat exchanger with internal microscale flow passages. The system includes a set of plates comprised of a polymer that includes internal microscale flow passages, which are configured to carry a liquid. The set of plates is organized into a stack, wherein consecutive plates in the stack are separated by fins to form intervening air passages. The system includes a liquid flow pathway, which flows from a liquid inlet, through the internal microscale flow passages in the stack of plates, to a liquid outlet. It also includes an airflow pathway, which flows from an airflow inlet, through the intervening air passages between the consecutive plates in the stack of plates, to an airflow outlet. The liquid flow pathway flows in a direction opposite to a direction of the airflow pathway to provide a counterflow design that optimizes heat transfer between the liquid flow pathway and the airflow pathway.

The heat exchanger includes at least one tube array in which refrigerant flows, the tube array includes a plurality of tubes each having a channel formed therein, and connection members coupled to opposite ends of the tubes so as to interconnect the tubes, and the tubes are injection molded integrally with the connection members.

Thermal management devices and systems, and corresponding manufacturing methods are described herein. A phase change thermal management device is manufactured with a method that includes forming a volume of a first material. The volume of the first material defines a chamber of the thermal management device and an inner surface of a port. A layer of a second material is electroplated on the volume of the first material. The volume of the first material is melted or dissolved, such that the electroplated layer of the second material forms the chamber and the port. The melted volume of the first material is removed via the port.

A method for manufacturing a thermoplastic heat exchanger for a battery module is provided. The method includes extruding a battery interface portion comprising a first thermoplastic composition and having a battery interface surface and a chamber surface opposite the battery interface surface; injection molding a base portion comprising a second thermoplastic composition having a channeled surface defining a plurality of channels and an outer surface opposite the channeled surface. The battery interface portion and the base portion are melt-bonded such that the chamber surface cooperates with the plurality of channels of the channeled surface to define a flow chamber for circulation of a thermal cooling fluid within the thermoplastic heat exchanger.

Air-to-air heat exchanger for ventilation systems with two countercurrent air flows disposed inside a cylindrical housing, a first air flow circulating inside the heat exchanger inside closed pipes, while the second air flow is in spaces between the pipes and cylindrical housing, and a fan moving the countercurrent air flows and disposed at one end of the cylindrical housing, with the fan including concentric inner and outer rings separated by a wall for moving air in opposite directions, a bunch of straight, parallel pipes whose end elements at the fan side are tightly gathered together, in the end of a cylindrical wall and, on the opposite side, in the end of a cylindrical pipe fitting, and between end elements, taper into middle sections between which are spaces, and a sleeve lining the inner wall of the housing at the middle sections and constricts the inner diameter of the housing.

The present disclosure provides a heat exchanger for a vehicle. The heat exchanger includes a relay block and a base member. The relay block has a first passage and a second passage. The relay block includes a first connecting surface and a second connecting surface. The base member is formed of plastic. The first connecting surface is configured to be connected to a first connector that is in fluid communication with a first in-vehicle component. The second connecting surface is configured to be connected to a second connector that is in fluid communication with a second in-vehicle component. Heat medium flows into the first in-vehicle component through the first passage and the heat medium flows into the second in-vehicle component through the second passage. The relay block is integrally formed with the base member by molding.

A heating block for use in a water heater for heating water, having a heating block body, in particular made of plastic, for forming a cavity for conducting the water and for receiving at least one heating element. The heating block body includes a first partial shell having a first sub-cavity and a second partial shell having a second sub-cavity. The first and the second partial shells are assembled in a joining region and form between them the cavity from the two sub-cavities. The joining region is not formed, at least partially, in a joining plane and/or the first and the second partial shells are welded together by the supply of heat via a medium, in particular, an essentially abrasion-free and/or vibration-free welding process, and/or the first partial cavity has a greater depth than the second partial cavity or vice versa.

A heat exchanger includes a core portion, a pair of header tanks, and an elastically-deformable sealing member. The header tanks are arranged on both end sides of the core portion. The header tank includes a core plate and a resin tank body, which define a tank space. The sealing member is disposed at an end part of the tank body located adjacent to the core plate. The sealing member has a loop shape to enclose the tank space when viewed from the core portion and is formed integrally with the end part of the tank body. The end part of the tank body includes a protrusion portion at least one of inward and outward of the sealing member. The protrusion portion encloses the tank space when viewed from the core portion and projects from the end part of the tank body toward the core plate.

The invention relates to a tube register (RR) for a heat exchanger (WT), in particular a heating element or cooling element, through which a heat transfer fluid may flow, and which has two distributor lines (1, 2), between which a plurality of connecting tubes (3) extend which fluidically connect the first distributor line, also referred to as the supply distributor (1), to the second distributor line, also referred to as the return distributor (2), the tube register having a linear supply distributor (1) and a linear return distributor (2) running in parallel thereto, between which a plurality of connecting tubes (3), situated in a plane, extend, the first ends (3a) of the connecting tubes (3) in each case being fluidically connected to the supply distributor (1), and the second ends (3b) of the connecting tubes (3) in each case being fluidically connected to the return distributor (2), characterized in that the connecting sites (P1) between the supply distributor (1) and the connecting tubes (3) are situated eccentrically, relative to the center axis (M1) of the supply distributor (1), on the supply distributor (1), and the connecting sites (P2) between the return distributor (2) and the connecting tubes (3) are situated eccentrically, relative to the center axis (M2) of the return distributor (2), on the return distributor (2).

An aluminum alloy has high thermal conductivity without requiring an addition of metal elements such as iron and a method for producing the aluminum alloy. The aluminum alloy is obtained from a semi-solid material with a chemical composition containing 2 to 6 wt % of silicon (Si) and 0.7 wt % or less of magnesium (Mg), with the balance being aluminum (Al) and unavoidable impurities. It has a granular crystalline structure. The aluminum alloy is produced by a heating step of semi-solid material. A forming step is performed with semi-solid material obtained in the heating step S1. After the forming step, a heat treatment step is performed at 190 C. to 290 C. for 1 to 5 hours.
