Description
Technical field
The utility model relates to evaporation structure, refers in particular to a kind of single process evaporimeter refrigerant side distributor.
Background technology
The single process evaporimeter is a kind of shell and tube evaporator, and it is a kind of heat exchanger, is at cold-producing medium and offers between user's the refrigerating medium and carry out heat exchange.Existing single process evaporation structure is as shown in Figure 1, and it comprises: package 11; One end of package 11 is the refrigerant side, and the refrigerant side is provided with refrigerant inlet 14, and the other end of package 11 is provided with refrigerant outlet 15, is communicated with by the heat exchanger tubes (not shown) that run through in the package 11 between refrigerant inlet 14 and the refrigerant outlet 15; The housing position of package 11 is provided with two refrigerating medium connectors 12,13, and refrigerating medium flows in shell.The housing contact site of cold-producing medium import and export 14,15 and package 11 is tightly connected respectively, and cold-producing medium gets into from cryogen import 14 and flows in the heat exchanger tubes and flow out from refrigerant outlet 15, makes the heat exchange of carrying out single process between cold-producing medium and the refrigerating medium.Above-mentioned cold-producing medium can be R134a, R22, R407C, R404A, R410a, R32 etc.Heat exchange tube material can be a copper, the corronil of any ratio, materials such as titanium can be light pipes, internal thread or male-pipe can be straight tubes, and can establish expand tube in the tube sheet place at two ends, also can bent intermediate and only at one end the tube sheet place establish expand tube.This evaporimeter can be used in the steam compression cycle handpiece Water Chilling Units of air, water/water form, naturally the cooling unit, energy lift unit and source pump.In order to reach best heat exchange effect; Refrigerant fluid in the heat exchanger tube should evenly distribute, and this is that refrigerating capacity is unstable because the tube refrigerant uneven distribution can cause the heating power of heat exchange in the evaporimeter uneven; Heat exchange efficiency reduces, and also can influence the service life of equipment simultaneously.
At present, making the equally distributed scheme of evaporator tube inner refrigerant generally is that the cold-producing medium inflow evaporator that is employed in the outer loop pipeline passes through a distributor before earlier, and cold-producing medium more easily is evenly distributed in the evaporator tube.But this type of distributor is all complicated for making cold-producing medium not reveal structure, and cost difficulty high, that keep high quality standards is big.In addition, this type of distributor is owing to complex structure, and volume is also big, and the space of leaving evaporimeter for diminishes, and directly influences heat exchange efficiency.
The utility model content
The purpose of the utility model is in order to overcome the problem that prior art exists, to provide a kind of simple in structure, and cost is low, need not take other space, can make the moving single process evaporimeter refrigerant side distributor of cold-producing medium stream with uniform distribution in the evaporator tube.
The purpose of the utility model realizes through following technical scheme:
Package, one of which end are the refrigerant side, and the refrigerant side is provided with refrigerant inlet, and the other end is provided with refrigerant outlet, and the housing contact site of refrigerant outlet and package is tightly connected; Be communicated with by the heat exchanger tube that runs through in the package between refrigerant inlet and the refrigerant outlet; The heat exchanger tube tube sheet place that is in the refrigerant side is provided with expand tube, and the housing contact site of expand tube and package is tightly connected, and said refrigerant inlet is located at the outside of expand tube; The housing position of package is provided with two refrigerating medium connectors, it is characterized in that:
Said distributor is fixed on the sagittal plane inwall in the said refrigerant side expand tube, and it is the plectane that a diameter and expand tube diameter are complementary, and plectane is provided with several equally distributed through holes.
Said distributor or metal material, or hard material plastics.
The both sides of said distributor are respectively equipped with a washer plate of fixing with the expand tube inwall.
The beneficial effect of the utility model:
Distributor in the utility model is owing to be mounted in the refrigerant side expand tube of single process evaporimeter; Do not take other space; Distributor is provided with equally distributed through hole, and the cold-producing medium that gets into heat exchanger tube in the evaporimeter can be moved by stream with uniform distribution, makes evaporimeter reach best heat exchange effect.This distributor need not other leakage-proof structure owing to be installed in the refrigerant side in the evaporimeter, and is therefore simple in structure, low cost of manufacture, long service life.
Be above-mentioned purpose, design feature and the effect that further specifies the utility model, below will combine accompanying drawing that the utility model is elaborated.
