Embodiment Construction
[0027] In order to make the objects, technical solutions, and advantages of the present invention more clearly, the technical solutions in the embodiments of the present invention will be described in contemplation in the embodiment of the present invention. It is an embodiment of the invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained without creative labor are not made in the premise of creative labor.
[0028] In the description of the invention, it is to be noted that the term "mount", "connected", "connection", such as a fixed connection, unless otherwise expressly specified and defined, unless otherwise expressly specified and defined. Connect, or integrate; may be mechanical connection, or electrical connection; may be directly connected, or indirectly connected by an intermediate medium, which can be in the interior of the two elements. The specific meaning of the above terms in the present invention will...

The invention relates to the technical field of heat exchange, and discloses a heat exchange plate and a microchannel heat exchanger. One surface of the heat exchange plate is provided with a fluid inlet, a fluid outlet and a plurality of fluid channels, and the two ends of each fluid channel are respectively connected to the fluid inlet and the fluid outlet. The channel length of the multiple fluid channels is adapted to the channel width, so that Multiple fluid channels are equalized in resistance to forward flow of fluid. In the heat exchange plate provided by the embodiment of the present invention, the channel length and channel width of the multiple fluid channels are set correspondingly, so that the resistance of the multiple fluid channels to the fluid flowing in the forward direction is equal, which is conducive to the even distribution of the fluid to the multiple fluid channels, thereby The problem of backflow caused by local uneven heating caused by uneven distribution of fluid flow in the existing microchannel heat exchanger is improved.
Description
Technical field [0001] The present invention relates to a heat exchange technology, and particularly relates to a heat exchanger plates and a microchannel heat exchanger. Background technique [0002] Microchannel heat exchanger passages are equivalent diameter 10μm ~ 1000μm heat exchanger, is a new and efficient heat exchanger. Compared with conventional heat exchangers, microchannel heat exchanger having a large specific surface, compact equipment and other advantages. Further, due to the compact heat exchanger structures, devices and therefore good compression performance, high reliability, has broad application prospect in refrigeration and air conditioning, power energy and many other areas. [0003] Typically, the microchannel heat flow field is more stable state, the heat transfer process can be carried out continuously, the channel width of each fluid passage in the conventional microchannel heat exchanger is typically equal, but the channel length of each fluid passagewa...
