The invention provides a special plate-fin heat exchanger capable of being conveniently inspected and installed, and relates to the field of heat exchangers. The heat exchanger comprises a core body,wherein the core body comprises a channel for fluid circulation, the channel comprises hot channels for hot fluid circulation and cold channels for cold fluid circulation, the hot channels and the cold channels are sequentially alternatively arranged from top to bottom, partition plates are arranged between the hot channels and the cold channels, the channels are in an annular shape, fins are arranged in the channels, the fins divide the channels into a plurality of fin channels, the fin channels are arranged in the radial direction of the channels, and the widths of the fin channels are gradually increased from the ends close to the circle centers of the channels to the other ends away from the circle centers of the channels. According to the special plate-fin heat exchanger capable of being conveniently inspected and installed, the widths of the fin channels are gradually increased from one ends to the other ends, and the problems that due to the fact that the width of a flow channelis not changed in the prior art, hot fluid is gradually cooled, so that the speed of the hot fluid becomes slow, and the heat transfer efficiency is low are solved.
Description
technical field [0001] The invention relates to the field of heat exchangers, in particular to a plate-fin heat exchanger which is convenient for special inspection and installation. Background technique [0002] Plate-fin heat exchangers are usually composed of partitions, fins, seals, and guide fins. Fins, deflectors and seals are placed between two adjacent partitions to form an interlayer, which is called a channel. Such interlayers are stacked according to different fluid methods and brazed into a whole to form a core body. The core body is a plate. The core of the finned heat exchanger. Plate-fin heat exchangers have been widely used in petroleum, chemical, natural gas processing and other industries. [0003] The width of the fin channel of the existing plate-fin heat exchanger remains unchanged. Due to the large temperature difference between the inlet and outlet fluids, the flow velocity difference between the inlet and outlet fluids is large. The fluid velocity a...
