Each fin type heat exchanger unit is composed of fin type heat exchangers. Separation distances between every two fin type heat exchangers are the same. All the fin type heat exchanger units are the same in the total number of heat exchangers. Each fin type heat exchanger is composed of heat exchange pipes, heat exchanged fins, end plates and converging pipes. The first fin type heat exchanger unit is formed by series connection of a plurality of fin type heat exchangers through the converging pipes. The second fin type heat exchanger unit is formed by parallel connection of an upper part and a lower part, and both the upper part and the lower part are composed of a plurality of fin type heat exchangers which are in series connection through converging pipes. The third fin type heat exchanger unit is formed by parallel connection of an upper part, a middle part and a lower part, and the upper part, the middle part and the lower part are all formed by series connection of a plurality of fin type heat exchangers which are in series connection through converging pipes. The fourth fin type heat exchanger unit is formed by parallel connection of four parts from top to bottom, and all the four parts are formed by a plurality of fin type heat exchangers which are in series connection through converging pipes. The fifth fin type heat exchanger unit is formed by parallel connection of six parts from top to bottom, and all the six parts are formed by a plurality of fin type heat exchangers which are in series connection through converging pipes.
Description
Technical field
The utility model relates to field of heat exchangers, relates in particular to a kind of efficient finned heat exchanger composite set.
Background technology
Finned heat exchanger is little with its floor space, compact conformation, simple to operate, heat transfer efficiency advantages of higher are widely used in the industries such as air-conditioning, electronic device heat exchange, HVAC, refrigeration, progressively in short supply along with the enhancing of social environment consciousness and the energy, the requirement of the utilization rate of heat exchanger is also more and more higher.And in order to improve heat exchange property, the mode of our common enhanced heat exchange namely improves the coefficient of heat transfer, increases heat exchange area, selects suitable air side and refrigerant side mean temperature difference.
Summary of the invention
Find by research, for the finned heat exchanger of giving fixed structure, in the situation that other parameter constants, when being definite value such as the air quantity of material, thickness, blower fan, EAT etc., in the situation that do not increase material cost, only change the feeder number of fin finned heat exchanger and the distribution of loop flow process, very large change will occur in the heat transfer characteristic of finned heat exchanger.This mainly is because the state of cold-producing medium in the shop can be divided into two-phase section and overheated zone.In two-phase section, keep its saturated evaporating temperature in whole loop during the cold-producing medium phase transformation; In the overheated zone, refrigerant vapour is in superheat state, and temperature is higher than saturated evaporating temperature, and simultaneously, cold-producing medium is far longer than convection transfer rate in the overheated zone at the boiling heat transfer coefficient of two-phase section.So reasonable Arrangement loop flow process makes cold-producing medium through in the whole process of finned heat exchanger, is in two-phase section, dwindles the overheated zone, so not only can improve the mean temperature difference of refrigerant side and air side, can also improve the whole coefficient of heat transfer as far as possible.
The utility model discloses a kind of finned heat exchanger composite set, formed by five groups or a times array finned heat exchanger unit of five, every group of unit forms by finned heat exchanger, and the spacing of every group of unit equates, the heat exchanger of every group of unit consists of the total identical of quantity, each finned heat exchanger is comprised of heat exchanger tube, heat exchange fin, end plate and header, and first group of unit is connected in series by header by a plurality of finned heat exchangers; Second group of unit forms by upper and lower two parts are in parallel, and every part is connected in series by header by a plurality of finned heat exchangers; The 3rd group of unit forms by upper, middle, and lower part is in parallel, and every part is connected in series by header by a plurality of finned heat exchangers; The 4th group of unit forms by four parts are in parallel from top to bottom, and every part is connected in series by header by a plurality of finned heat exchangers; The 5th group of unit forms by six parts are in parallel from top to bottom, and every part is connected in series by header by a plurality of finned heat exchangers.
The utility model finned heat exchanger composite set, the heat exchanger tube of its all heat exchangers is all on same level, heat exchanger tube is riffled tube, two ends maintain static by end plate, in heat-conducting gas or liquid are arranged, after heat exchanger tube one end radially passes fin, crooked radially penetrate fin from rear round again after oppositely, until pass on the fin behind all rounds, link to each other with header; Fin is corrosion-resistant hydrophilic aluminium foil, and the parallel interval that is separated by equates between a plurality of heat exchange fins, and the interval between each hole on the fin also equates.
The beneficial effects of the utility model are, need not carry out change on the parameter to finned heat exchanger, and only carry out the arrangement of flow arrangement, make its heat exchange and mobile aspect characteristic change, when refrigerant flow one timing, pipe group connected mode by optimum should make both resultant effects best, not only provides cost savings, and has more obtained higher heat exchange amount.

The specific embodiment
Structural representation of the present utility model as shown in Figure 1, 2, in the cellular construction of the utility model finned heat exchanger composite set, formed by five groups or a times array finned heat exchanger unit of five, every group of unit forms by finned heat exchanger, and the spacing of every group of unit equates, the heat exchanger of every group of unit consists of the total identical of quantity, and each heat exchanger has a plurality of parallel heat exchange fins of being separated by, and many row's punchings are arranged on each fin; Heat exchanger tube vertically passes fin by hole, and the heat exchanger tube two ends maintain static by end plate; Header is comprised of knockout, separating tube and muffler, is connected with heat exchange pipe head respectively.
During work, heat-conducting liquid or the gas knockout by the header end is carried out purification separation, the heat exchanger tube that enters the top heat exchanger of every group of every part by separating tube enters, flow out from the heat exchanger tube of end heat exchanger, need this moment air-flow or the liquid of heat exchange to pass through successively from left to right 1 to 5 group of heat exchanger unit, carry out exchange heat through heat exchanger tube and fin with every group of heat exchanger, to reach desirable temperature.
