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 order in public building, to bring pleasant environment for 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 be arranged in building the sensation that spring has set in.Condenser is used for the heat exchanger that the high temperature refrigerant steam after the compressor compresses is cooled off and 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 by 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, liquid outlet end at trumpet cooler, generally also be provided with supercooling tube, guarantee the further cooling from the condenser fluid, but in this kind method, the low-temperature receiver of supercooling tube is the cooling water that enters from the external world, is subjected to 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 coolant medias; 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 simultaneously whole unit refrigerating capacity.But the structure of this split type condenser is very complicated, and parts are various, and trouble is installed, and overall volume is larger, and it is also larger to take up room, so that the floor space of whole central air-conditioning is 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 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 by 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 large.This heat exchanger is that the multi-disc plate type heat exchanger is closely connected, set up flow deflector in the centre and formed 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 form, cold liquid is through preheating and sterilization, flows out emit heat in fin after, 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 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.

That is to say that the sectional area of described diversion groove can be selected to be set to equate fully with the area of passage of the water conservancy diversion interface at two ends, also can be slightly larger than or be slightly less than the area of passage of the water conservancy diversion interface at two ends.The sectional area that its scope definition that is slightly larger than or is slightly less than is described diversion groove is compared to differ up and down with the area of passage of the water conservancy diversion interface at two ends and is no more than 10%, preferably is no more than 5%.
In the above-mentioned plate-type condenser, described diversion groove is shaped to streamlined.
In the above-mentioned plate-type condenser, form pod apertures and a plurality of regularly arranged heat exchange groove for the conducting heat transferring medium on the plate face of described condensing heat-exchange sheet and the cold heat exchanger fin of described mistake.
In the above-mentioned plate-type condenser, described heat exchange groove is herringbone, and adjacent described heat exchange groove is positive herringbone and the setting of falling the herringbone.
In the above-mentioned plate-type condenser, adjacent described condensing heat-exchange sheet and the described pod apertures (112) of the cold heat exchanger fin of described mistake locate to adopt seal gasket to be connected and sealed.
In the above-mentioned plate-type condenser, the two ends of described condenser arrange the heat exchange end cap.
In the above-mentioned plate-type condenser, be welded to connect between described heat exchange end cap, described condensing heat-exchange sheet, described deflector, the cold heat exchanger fin of described mistake.
In the above-mentioned plate-type condenser, enter into the economizer interface of compressor behind the described excessively cold-zone of described excessively cold fluid process, tonifying Qi increases enthalpy to compressor.
Technique scheme of the present invention has the following advantages compared to existing technology:
(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, and cross the cold-zone and separate by a deflector with condensing zone, the compact conformation of whole condenser, 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 increases the refrigerating capacity of unit to compressor.And above-mentioned all functions are integrated, and are easy to process, are convenient to install.
