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 the city, Hotel's Executive building get more and more; As everyone knows, in public building, bring pleasant environment in order to give people, most large public buildings have all been equipped central air-conditioning; Central air-conditioning can be controlled room temperature within certain temperature range, make people that the four seasons arranged in building the sensation that spring has set in.Condenser is used for high temperature refrigerant steam cooled after the compressor compresses and the heat exchanger that makes it to liquefy as the vitals of central air-conditioning.
What the condenser of the central air-conditioning that market is common adopted basically is pipe heat exchanger, and cold-producing medium carries out heat exchange through the heat exchanger tube that is arranged in the outer cover of heat exchanger with extraneous water, realizes refrigeration.For the condensation efficiency that makes condenser is further improved,, generally also be provided with supercooling tube at the liquid outlet end of trumpet cooler; Guarantee further cooling from the condenser fluid; But in this kind method, the low-temperature receiver of supercooling tube is the cooling water that gets into from the external world, receives the restriction (about 30 ℃ of coolant water temperatures) of low-temperature receiver; The degree of supercooling of this condenser is relatively low, and heat exchange efficiency is also relatively low.Because this supercooling tube can only be communicated with the cooling water of GB requirement and can not be communicated with other refrigerant media; Therefore; As new technological trend; In the middle of the application of trumpet cooler, be equipped with board-like subcooler in that the fluid pipeline section of condenser is standing, utilize board-like subcooler to realize the heat exchange between the cryogenic refrigeration medium after refrigerant and the throttling; Further improve the degree of supercooling of condenser, so just can improve whole unit refrigerating capacity simultaneously.But this split type structure of condenser is very complicated, and parts are various, and trouble is installed, and overall volume is bigger, and it is also bigger to take up room, and makes that the floor space of whole central air-conditioning is bigger.
Complicated for solving condenser structure, the dutycycle problem of higher, document us US2010/0065262Al discloses a kind of plate type heat exchanger, and it can be used as condenser and uses.The heat exchanger structure of its relative tubular type is simple, and floor space is little; But it does not make the further supercooling apparatus of cooling of condenser, and therefore, the condensation efficiency of this condenser can not meet the demands.And in the prior art, it also is the split-type structural that connects through pipeline that this board-like condenser installs subcooler additional.Its floor space still can not satisfy the requirement of compact central air conditioner system.
Chinese patent file CN2604667Y discloses a kind of plate type heat exchanger that integrates preheating, sterilization, cools off.For solve sterilization in the prior art and fast cooling adopt two cover autonomous devices move simultaneously the using energy source of existence insufficient, waste water and problem that equipment investment is big.This heat exchanger is that the multi-disc plate type heat exchanger is closely connected, and has set up flow deflector in the centre and has formed waste heat exchange area and high-temperature sterilization district, and it is by preheating sheet 1, sterilization sheet 4, fin 2; Flow deflector 3 and 5 compositions of heat sheet; Cold liquid is through preheating and sterilization, flows out after in fin, emitting heat, and high-temperature medium can be with hot water or superheated vapor; In heating plate, emit heat, because they connect tight heat and can fully exchange.But the interior shape of the deflector 3 in this plate type heat exchanger is a parallelogram, can cause rate of flow of fluid too small during fluid process deflector 3, finally causes heat exchange efficiency lower, can not satisfy the requirement of the condenser heat exchanging efficient in the central air-conditioning.
Summary of the invention
For this reason, technical problem to be solved by this invention is the problem that existing condenser takes up room greatly, heat exchange efficiency is low, and then provides a kind of dutycycle little, the condenser that heat exchange efficiency is high.
For solving the problems of the technologies described above, plate-type condenser of the present invention, it comprises condensing zone, said condensing zone closely is formed by connecting a plurality of condensing heat-exchange sheets, is used to realize the heat exchange of refrigerant and cooling fluid; Cross the cold-zone, the said cold-zone of crossing closely is formed by connecting the cold heat exchanger fin of a plurality of mistakes, is used to realize through the refrigerant behind the said condensing zone and the heat exchange of cryogenic liquid; Said condensing zone and the said cold-zone of crossing isolate through a deflector; Said deflector is provided with and is used for the condensed said refrigerant of said condensing zone is guided to the said diversion groove of crossing the cold-zone, and the sectional area of said diversion groove equates with the area of passage of the water conservancy diversion interface at two ends.
In the above-mentioned plate-type condenser, form the pod apertures and a plurality of regularly arranged heat exchange groove that are used for the conducting heat transferring medium on the plate face of said condensing heat-exchange sheet and the cold heat exchanger fin of said mistake.
In the above-mentioned plate-type condenser, said heat exchange groove is herringbone, and the said heat exchange groove on the adjacent heat exchanger fin is positive herringbone and the setting of falling the herringbone.
In the above-mentioned plate-type condenser, the adjacent said condensing heat-exchange sheet and the said pod apertures place of the cold heat exchanger fin of said mistake adopt seal gasket to be connected and sealed.
In the above-mentioned plate-type condenser, the two ends of said condenser are provided with the heat exchange end cap.
In the above-mentioned plate-type condenser, be welded to connect between said heat exchange end cap, said condensing heat-exchange sheet, said deflector, the cold heat exchanger fin of said mistake.
In the above-mentioned plate-type condenser, enter into the economizer interface of compressor behind the said cold-zone excessively of the said process of cold fluid excessively, tonifying Qi increases enthalpy to compressor.
Technique scheme of the present invention is compared prior art and is had the following advantages:
(1) condenser of the present invention adopts the plate-type heat-exchange sheet to realize heat exchange, and it has increased by one and cross the cold-zone, crosses the cold-zone and separates through a deflector with condensing zone, and whole structure of condenser is compact, and split type condenser floor space is lower with respect to having now; Simultaneously, the sectional area of the diversion groove that deflector of the present invention is offered equates with the sectional area of two end interfaces, makes the flow velocity of refrigerant stable in air deflector, and heat exchange efficiency improves greatly.
(2) offer a plurality of regularly arranged heat exchange grooves on the heat exchanger plates of the present invention and be used for flowing of heat transferring medium; This heat exchange groove is herringbone; With respect to the existing heat exchange plate that the heat exchange groove is not set, the heat exchange efficiency between the heat exchanger plates of the present invention further improves.
(3) during the present invention's crossing cold fluid and passed through the cold-zone after the choke valve throttling, can realize overheated to the refrigerant after the throttling, direct compensation is given compressor, increases the refrigerating capacity of unit.And above-mentioned all functions are integrated, and are easy to process, are convenient to install.
