Description
Technical field
The invention belongs to the design and manufacturing technology field of heat exchanger, particularly a kind of plate-type condenser.
Background technology
At present, high buildings and large mansions in city, Hotel's Executive building are more and more, as everyone knows, in public building, pleasant environment is brought in order to give people, most large public building is all equipped with central air-conditioning, central air-conditioning can control room temperature within certain temperature range, make people have four seasons in building the sensation that spring has set in.Condenser as the vitals of central air-conditioning, for the temperature refrigerant vapor after compressor compresses is cooled and make it liquefy heat exchanger.
What the condenser of the central air-conditioning that market is common adopted substantially is pipe heat exchanger, and cold-producing medium carries out heat exchange by the heat exchanger tube be arranged in outer cover of heat exchanger with extraneous water, realizes refrigeration.Be further improved to make the condensation efficiency of condenser, at the liquid outlet end of trumpet cooler, generally also be provided with supercooling tube, ensure the further cooling from condenser fluid, but in this kind of method, the low-temperature receiver of supercooling tube is the cooling water entered from the external world, by the restriction (coolant water temperature about 30 DEG C) of low-temperature receiver, the degree of supercooling of this condenser is relatively low, and heat exchange efficiency is also relatively low.Other coolant medias can not be communicated with because this supercooling tube can only be communicated with the cooling water of Standard; Therefore, as new technological trend, in the middle of the application of trumpet cooler, set up at the fluid pipeline section of condenser and be equipped with board-like subcooler, utilize board-like subcooler to realize the heat exchange after refrigerant and throttling between cryogenic refrigeration medium, the degree of supercooling of further raising condenser, so just can improve whole unit refrigerating capacity simultaneously.But the structure of this split type condenser is very complicated, and parts are various, install trouble, overall volume is comparatively large, takes up room also larger, makes the floor space of whole central air-conditioning larger.
Complicated for solving condenser structure, the problem that dutycycle is higher, U.S. patent documents US2010/0065262Al discloses a kind of plate type heat exchanger, and it can use as condenser.The heat exchanger structure of its relative tubular type is simple, and floor space is little; But its supercooling apparatus not making condenser cool further, therefore, the condensation efficiency of this condenser can not meet the demands.And in prior art, it is also the split-type structural connected by pipeline that this board-like condenser installs subcooler additional.Its floor space still can not meet the requirement of compact central air conditioner system.
Chinese patent document CN2604667Y discloses and a kind ofly integrates preheating, sterilizing, the plate type heat exchanger that cools.For solve sterilization in prior art and fast cooling employing two overlap autonomous device run simultaneously the using energy source of existence insufficient, waste water and problem that equipment investment is large.This heat exchanger is closely connected by multi-disc plate type heat exchanger, set up flow deflector in centre and form waste heat exchange area and high-temperature sterilization district, it is by pre-backing 1, sterilization sheet 4, fin 2, flow deflector 3 and high-temperature heating sheet 5 formed, cold liquid, through preheating and sterilization, flows out after releasing heat in fin, and high-temperature medium can with hot water or superheated vapor, in heating plate, release heat, can fully exchange because they connect tight heat.But the interior shape of the deflector 3 in this plate type heat exchanger is parallelogram, fluid can cause rate of flow of fluid too small when deflector 3, finally causes heat exchange efficiency lower, can not meet the requirement of the condenser heat exchanging efficiency in central air-conditioning.
Summary of the invention
