Description
Technical field
The present invention relates to a kind of air-condition heat exchanger, relate in particular to a kind of heat exchanger for nuclear power air-conditioning unit.
Background technology
The air-conditioning unit heat exchanger of nuclear power plant generally still adopts the heat exchanger of common air-conditioning unit on the market at present, its structure is generally by deckle board is installed, be installed on the heat exchanger tube in the deckle board, go here and there on heat exchanger tube radiating fin and be connected water inlet pipe and outlet pipe with heat exchanger tube, it is regulated, and heat exchange amount normally realizes by the temperature of regulating the intraductal heat exchange water of intaking or steam flow size, though this kind regulative mode can play the effect of regulating the heat exchange amount, but the phenomenon of leaking or leaking gas can appear in its control valve of regulating hot water or steam flow in long-term the use, maintenance load is big, also potential safety hazard can appear, influencing unit normally moves, and owing to safeguard that the space is less, keep in repair very difficultly, but the design service life of nuclear power plant all will reach about 60 years, this kind heat exchanger is difficult to reach requirement, haves much room for improvement.
The Chinese patent publication number is CN 2273388, a kind of double-side pattern moving louver casing heater cover is disclosed, characteristics are that the stepped movable blinds in upper end connects housing and the drive link that raised tooth is arranged respectively, and the upset that is provided with interlock stirs dish, and it is reasonable in design, and is simple in structure, make easily, with low cost, easy to use, the heating phase with blinds be rotated into 90 the degree or other angle can strengthen area of dissipation; Blinds can be rotated into 0 degree or 180 degree plane display pattern colors and prevent that dust from entering at non-heating period, also can be transformed into back side pattern, its linkage is good, and is interesting strong, both artistic and practical, is suitable for the heating installation finishing and selects for use, is suitable for penetration and promotion.This technical scheme also is the adjusting vane connection bar linkage structure by louver structure, control area of dissipation by the flip angle of blinds and reach adjusting heat dissipation capacity and indoor temperature, those skilled in the art can associate the heat exchange amount of utilizing this kind mechanism to regulate existing heat exchanger rather than regulate the heat exchange water or quantity of steam reaches the purpose of regulating heat exchange by control valve, but this technical scheme adjusting vane is common louver structure, can only control whole unlatching and the closure in a certain surface that makes the deckle board that heat exchanger tube is installed, can not control the heat exchange amount accurately, and in the heat exchanger course of work, do not allow to occur the phenomenon of unitary closed, must leave the air channel and carry out circulation of air, not so can cause that heat exchanger tube is overheated to be burnt out, if accumulate dust easily again and influence the service life of fin on the heat exchanger tube but be in the semi-closed state for a long time, have much room for improvement.
Summary of the invention
The present invention is for solving the deficiencies in the prior art, provide a kind of need not regulate heat exchange water and steam flow can realize changing heat-regulatory, long service life, easy to maintenance and can accurately regulate the nuclear power air-conditioning unit heat exchanger of heat exchange amount.
Key problem in technology of the present invention is that the heat exchanger tube that will install in the deckle board is divided into some groups that arrange at interval, and at every group of heat exchanger tube installation heat exchange volume adjusting apparatus, control the heat exchange amount of heat exchanger tube by the adjusting vane flip angle in the adjusting heat exchange volume adjusting apparatus, can finish in its adjusting vane switching process every group of heat exchanger tube surface covered gradually and close, open gradually in air channel between the two adjacent groups heat exchanger tube, be implemented in and reserve certain ventilation air channel when reducing the heat exchange amount, when increasing the heat exchange amount, the air channel is closed, wind is passed through between heat exchanger tube fully, improve the accuracy of heat exchange effect and adjusting.Concrete technical scheme is: a kind of nuclear power air-conditioning unit heat exchanger, comprise square installation deckle board, install in the deckle board and be set side by side with some end to end heat exchanger tubes, be serially connected with radiating fin on the heat exchanger tube, it is characterized in that described heat exchanger tube is divided at least two groups, every group first and inlet channel and the outlet conduit of last root heat exchanger tube termination connection installation deckle board one side, every group of heat exchanger tube and the gap of installing between deckle board plate body or the adjacent heat exchange tubes group constitute the air channel, and the both sides up and down of described every group of heat exchanger tube are provided with the heat exchange volume adjusting apparatus that can regulate air channel size and heat exchanger tube ventilation.
Described heat exchange volume adjusting apparatus comprises rotating shaft, is fixedly connected on the adjusting vane of rotating shaft and the adjusting linkage that flexibly connects with rotating shaft, described adjusting vane is that strip plate body two ends constitute two ends kink and horizontal part along long spring folding, the mutual level of described two ends kink, described rotating shaft is connected and fixed on a kink, the upset of rotation control and regulation blade.
Described every group of heat exchanger tube both sides adjusting vane up and down is symmetrical arranged, when the adjusting vane horizontal part turn to level, the kink that is connected with rotating shaft seals the air channel, every group of scavenge trunk surface ventilates fully, when the kink of adjusting vane turn to level, sealing was closed by the horizontal part cover of symmetrical adjusting vane in every group of heat exchanger tube surface.
As preferably, described heat exchange volume adjusting apparatus is arranged at front and/or the back side of every group of heat exchanger tube.
Beneficial effect of the present invention: the service life that the present invention has improved equipment greatly by this kind setting, and effectively prevent leaking or gas leak phenomenon of prior art adjusting generation, and effectively improved the heat exchange effect, be fit to nuclear power plant's higher requirement.
