Description
Technical field
The present invention relates to a kind of air-condition heat exchanger, particularly relate to a kind of heat exchanger for nuclear power air-conditioner set.
Background technology
The air-conditioner set heat exchanger of current nuclear power plant generally still adopts the heat exchanger of common air-conditioning unit on the market, its structure is generally by installation deckle board, be installed on the heat exchanger tube in deckle board, go here and there the radiating fin on heat exchanger tube and be connected water inlet pipe and outlet pipe with heat exchanger tube, it regulates the temperature or steam flow size of heat exchange amount normally by regulating water inlet intraductal heat exchange water to realize, though this kind of regulative mode can play the effect regulating heat exchange amount, but it regulates the control valve of hot water or steam flow to there will be the phenomenon of leaking or leaking gas in Long-Time Service, maintenance load is large, also there will be potential safety hazard, affect unit normally to run, and owing to safeguarding that space is less, keep in repair very difficult, but the design service life of nuclear power plant all will reach about 60 years, this kind of heat exchanger is difficult to reach requirement, have much room for improvement.
China Patent Publication No. is CN 2273388; disclose a kind of Double-side pattern moving louver casing for radiator; feature is that the stepped movable shutters in upper end connects housing and the drive link having raised tooth respectively; and being provided with the upset shifting disc of interlock, it is reasonable in design, and structure is simple; make easily; with low cost, easy to use, blinds is rotated into 90 degree or other angle can strengthen area of dissipation at Heating Period; Blinds can be rotated into 0 degree or 180 degree of plane display pattern colors at non-heating period and prevent dust from entering, also can be transformed into rear surface pattern, its linkage is good, interesting strong, both artistic and practical, is suitable for heating installation finishing and selects, be suitable for penetration and promotion.This technical scheme is also connect bar linkage structure by the adjusting vane of louver structure, control area of dissipation by the flip angle of blinds and reach adjustment heat dissipation capacity and indoor temperature, those skilled in the art can associate and utilize this kind of mechanism to regulate the heat exchange amount of existing heat exchanger instead of to regulate heat exchange water or quantity of steam to reach the object regulating heat exchange by control valve, but this technical scheme adjusting vane is common louver structure, the opening and closing of a certain surface integral making the deckle board of installation heat exchanger tube can only be controlled, heat exchange amount can not be controlled accurately, and in the heat exchanger course of work, do not allow the phenomenon occurring unitary closed, air channel must be left and carry out air circulation, not so can cause that heat exchanger tube is overheated to be burnt out, if but be in semi-closed state for a long time and easily accumulate dust again and affect the service life of fin on heat exchanger tube, have much room for improvement.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides one and heat exchange water and steam flow need not be regulated can to realize changing heat-regulatory, long service life, easy to maintenance and can the heat exchanger of nuclear power air conditioner unit of fine adjustment heat exchange amount.
Key problem in technology of the present invention is the heat exchanger tube installed in deckle board to be divided into spaced some groups, and heat exchange volume adjusting apparatus is installed often organizing on heat exchanger tube, by the heat exchange amount regulating the adjusting vane flip angle in heat exchange volume adjusting apparatus to control heat exchanger tube, can complete in its adjusting vane switching process and cover conjunction gradually by often organizing heat exchanger tube surface, air channel between two adjacent groups heat exchanger tube is opened gradually, realize reserving certain ventilation air duct while minimizing heat exchange amount, while increase heat exchange amount, air channel is closed, wind is passed through completely between heat exchanger tube, improve the accuracy of heat transfer effect and adjustment.Concrete technical scheme is: a kind of heat exchanger of nuclear power air conditioner unit, comprise square installation deckle board, install in deckle board and be set side by side with some end to end heat exchanger tubes, heat exchanger tube is serially connected with radiating fin, it is characterized in that described heat exchanger tube is divided at least two groups, first that often organizes to be communicated with the inlet channel and outlet conduit of installing deckle board side with last root heat exchanger tube termination, the formation air channel, gap often organized heat exchanger tube and install between deckle board plate body or adjacent heat exchange tubes group, the described both sides up and down often organizing heat exchanger tube are provided with the heat exchange volume adjusting apparatus of adjustable air duct size and heat exchanger tube ventilation.
The regulating connecting rod mechanism that described heat exchange volume adjusting apparatus comprises rotating shaft, is fixedly connected on the adjusting vane of rotating shaft and is flexibly connected with rotating shaft, described adjusting vane is that strip plate body two ends form 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, rotates the upset of control and regulation blade.
Described heat exchanger tube upper and lower both sides adjusting vane of often organizing is symmetrical arranged, when adjusting vane horizontal part turn to level, air channel is closed by the kink be connected with rotating shaft, often organize scavenge trunk surface to ventilate completely, when the kink of adjusting vane turn to level, often organize heat exchanger tube surface and closed by the horizontal part cover of symmetrical adjusting vane closed.
As preferably, described heat exchange volume adjusting apparatus is arranged at the front and/or the back side of often organizing heat exchanger tube.
Beneficial effect of the present invention: the present invention substantially increases the service life of equipment by this kind of setting, and effectively prevent prior art from regulating leaking or gas leak phenomenon of generation, and effectively improve heat transfer effect, the requirement that applicable nuclear power plant is higher.
