An exhaust gas heat exchanger may include a tube bundle and a housing through which a coolant is flowable. The tube bundle may include a plurality of exhaust gas-conducting tubes held in a first tube base and a second tube base. The housing may enclose the tube bundle and may have face ends delimited by the first tube base and the second tube base. The housing may include a coolant inlet arranged in a region of the second tube base and a coolant outlet arranged in a region of the first tube base such that the coolant flows in counter flow relative to the exhaust gas. A plurality of coolant bypass passages may be arranged between the tube bundle and the housing. At least a subset of the plurality of coolant bypass passages may be at least partly blocked by an inlay structured and arranged to steer a coolant flow.

The purpose of the present invention is to provide a plate-type heat exchanger in which the formation of burrs and chips during fin processing may be eliminated by eliminating fin processing work for stacking and bonding fins and plates. In order to achieve the above purpose, a plate-type heat exchanger according to the present invention is characterized by comprising: plates which include an inlet formed on one side in the longitudinal direction, an outlet formed on the other side in the longitudinal direction, and a flow surface formed between the inlet and the outlet; and a fin part which is inserted into a plate part formed by bonding a pair of the plates and rests on the flow surface. The plates include a fin part movement preventing means to ensure that one end of the fin part in the longitudinal direction is spaced a certain distance from the inlet and the other end of the fin part in the longitudinal direction is spaced a certain distance from the outlet such that the fin part rests only on the flow surface.

A heating and cooling (HVAC) system that includes a compressor; a first heat exchanger; a second heat exchanger; a first expansion valve positioned between the first heat exchanger and the second heat exchanger; a first reversing valve that permits the system to operate in a first mode and a second mode; and a thermal battery including a phase change material therein that is configured to selectively store and release thermal energy received from a working fluid.

A heat exchanger 100 includes: an inner cylinder 10 through which a first fluid can flow, the inner cylinder 10 being configured to be capable of housing a heat recovery member 40; an outer cylinder 20 disposed so as to be spaced on a radially outer side of the inner cylinder 10 such that a second fluid can flow between the outer cylinder 20 and the inner cylinder 10; and an intermediate cylinder 30 disposed between the inner cylinder 10 and the outer cylinder 20, the intermediate cylinder 30 partitioning a flow path for the second fluid into an inner flow path 31b and an outer flow path 31a. In the heat exchanger, the intermediate cylinder 30 includes communication holes 32 that are communicated in a radial direction, and the communication holes 32 are provided in an axial direction of the intermediate cylinder 30.

A heat exchanger for an internal combustion engine transfers heat between fluids and includes a housing having a housing wall and a housing interior bordered at least in regions by the housing wall. The housing interior has a fluid inlet region for introducing a first fluid of the fluids into the housing interior and a fluid outlet region for discharging the first fluid out of the housing interior. The heat exchanger has at least two partition walls, which are at least substantially accommodated in the housing interior and connected to the housing wall of the housing at at least one connection region. The partition walls border at least regions of a fluid receiving chamber, through which a second fluid of the fluids can flow, in order to separate the fluids from one another. The partition walls are connected to one another at least at a joining region associated with the fluid inlet region and adjacent to the fluid receiving chamber in a main fluid flow direction of the first fluid. The partition walls also have a deformation, at least in a joining sub-region of the joining region spaced apart from the connection region, which is provided to at least reduce mechanical tension in the at least one connection region due to a temperature-dependent change in length of the joining region.
