Abstract
A ring-type parallel-flow heat exchanger is provided. It comprises a lining as heat exchange fluid chamber formed by enclosing a corrugated tube in a housing, a fluid inlet disposed in the housing, more than two baffles installed inside the lining. The cavity of the corrugated tube serves as a heat exchange chamber for heat media in the heat exchanger. The baffles are attached tightly to the surface of the corrugated tube, to form a plurality of parallel ring slots; and can separate the corrugated tube from the housing, to form a space for fluid storage. The direction of fluid inlet is just opposite to that of the gas inlet, so that the efficiency of heat exchange is increased. The ring-type parallel-flow heat exchanger has simple structure, easy production, high-efficiency and uniform heat exchange, small size, and good anti-vibration performance.
Description
Affiliated technical field:
The utility model relates to a kind of heat exchanger, and refering in particular to is a kind of annular parallel-flow heat exchanger.
Technical background:
Heat exchanger is widely used in fields such as chemical industry, oil, pharmacy, heating and ventilation project because of it, thereby has produced the heat exchanger of the multiple model specification that is applicable to that different occasions are used, and being mainly used in the pipeline thermal exchanged form modal mainly is pipe heat exchanger.It is to be made of termination, end socket, dividing plate, heat exchange box etc.Though have advantage simple in structure, that cost is low, because the problem that its structural design exists, the caliber of employing is bigger, and radiating tube is long, thereby, make its heat exchange efficiency lower, the pipe resistance is bigger, the heat exchange lack of homogeneity, bulky, the anti-vibration performance is poor, has seriously restricted its applicable scope.Though plate type heat exchanger heat exchange efficiency height, the unfavorable enterprising promoting the circulation of qi liquid of pipeline that is applied to of structure exchanges.More and more pay attention to recycling epoch of hot machine used heat people, present existing heat exchanger is low to being applied to the used heat temperature, and the little effect in space is undesirable, is not that volume is exactly too greatly that the rate of recovery is not high, has seriously restricted the development of the recycling of used heat.
Summary of the invention:
The purpose of this utility model is to overcome the prior art deficiency and provides a kind of simple and reasonable, the heat exchange efficiency height, and temperature difference resistance is good, long service life, the uniform ring-like concurrent flow high-performance heat exchanger of heat exchange.
The utility model is to adopt following proposal to realize: bellows is placed in forms interlayer in the shell as the heat exchange sap cavity, the liquid in-out mouth is located on shell, two liquid collecting dividing plates on minimum will the clamping in the interlayer of bellows and shell formation, the interior tube chamber of bellows is then as the heat exchanging chamber of thermal medium in heat exchanger.Like this, the ripple tongue and groove peak and the liquid collecting dividing plate that utilize bellows itself to be had are close to a lot of bar parallel annular grooves of composition, and the liquid collecting dividing plate, make to have distance between bellows and the shell and form liquid collecting cavity, make heat transferring medium can be rapidly and uniformly parallel circulation and come together in liquid in-out mouth place in each section cannelure.
If when not clamping the liquid collecting dividing plate, then can be on shell or bellows minimumly be provided with two and be parallel to the axial heat accumulator of heat exchanger, be used for compiling fast the heat transferring medium that passes in and out annular parallel slot, ripple tongue and groove peak that bellows itself is had and shell are close to and are formed a lot of bar parallel annular grooves, and heat transferring medium can parallel circulation in each section cannelure rapidly and uniformly.
If when not using bellows to do the heat exchanger inner core, heat exchanger core also can be no less than one parallel heat-transfer pipe of ring-type and header by one group of quantity and form.
Heat transferring medium is the flow process circulation by annular concurrent flow in heat transfer process, and liquid heat transferring medium is mixed with the gaseous state heat transferring medium again, can improve heat exchange efficiency greatly; This multichannel is arranged in parallel and makes the loss of heat transferring medium lateral pressure little simultaneously, and heat transferring medium flow velocity height also can effectively improve heat transfer efficiency, so more helps owing to reclaim low-temperature heat source.Because heat exchanger core is to be made of bellows or the parallel heat transfer tube group of ring-type, these two kinds of structures itself all have self extension compensate function, and the tube sheet thermal stress is very little, can not leak because of the mouth of pipe breaks, and has guaranteed service life.Volume is small and exquisite and in light weight, conveniently is applied to install compact space.Describe in detail below in conjunction with the embodiment accompanying drawing.
