Embodiment Construction
[0033] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0034] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.
[0035] Such as Figure 1 to Figure 7 As shown,...

The invention relates to the technical field of heat exchange devices and particularly relates to a heat exchanger. The heat exchanger comprises a heat exchange core, a by-pass structure, a front endchamber and a rear end chamber. The by-pass structure comprise a by-pass pipeline, the heat exchange core and the by-pass pipeline communicate with the part between the front end chamber and the rearend chamber, the by-pass structure further comprises a heat exchange shell arranged outside the by-pass pipeline, and a heat exchange channel is formed by the space between the inner wall of the heatexchange shell and at least partial outer wall of the by-pass pipeline; and a medium inlet and a medium outlet are formed in the heat exchange shell. The flowing direction of the second medium is defined by the heat exchange channel and is around the periphery of the by-pass pipeline all the time, so that the second medium can carry out heat exchange with the first medium in the by-pass pipeline in a concentrated mode, and the heat exchange efficiency can be improved; and besides, constant circulation of the second medium can be achieved through the heat exchange channel, so that stability ofthe temperature difference between the second medium and the first medium can be maintained, and thus the heat exchange efficiency can be further improved.
Description
technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a heat exchanger and a heat exchange system. Background technique [0002] EGR is the abbreviation of Exhaust Gas Re-circulation, that is, the abbreviation of exhaust gas recirculation. Exhaust gas recirculation refers to the return of part of the exhaust gas from the engine to the intake manifold, and re-enters the cylinder together with the fresh mixture. Due to the large amount of CO contained in the exhaust gas 2 and other polyatomic gases, while CO 2 The gas cannot be burned but absorbs a large amount of heat due to its high specific heat capacity, which reduces the maximum combustion temperature of the mixture in the cylinder, thereby reducing the amount of NOx produced, and then meeting the emission standards. [0003] A heat exchanger, usually called an EGR cooler, is usually used in the EGR system to cool the exhaust gas. One is used in the EGR system an...
