Description
Technical field
The utility model relates to two pass evaprator, refers in particular to a kind of two pass evaprator refrigerant side distributor.
Background technology
Two pass evaprator 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 two pass evaprator structure is as shown in Figure 1, and it comprises: package 11; One end of package 11 is the refrigerant side of evaporimeter; The refrigerant side is provided with two adjacent refrigerant inlet 14 and refrigerant outlet 15; By running through in the package 11 and the heat exchanger tubes (not shown) that turn back of turning are communicated with, the housing contact site of cold-producing medium import and export 14,15 and package 11 is tightly connected respectively between refrigerant inlet 14 and the refrigerant outlet 15; The housing parts of package 11 is provided with two refrigerating medium connectors 12,13, and refrigerating medium flows in shell.Cold-producing medium gets in the heat exchange tube from refrigerant inlet 14 and flows, and behind the other end of arrival package 11, turns with heat exchanger tube and goes back to the refrigerant side, and flow out from refrigerant outlet 15, makes the heat exchange of carrying out double-current journey between cold-producing medium and the refrigerating medium.Above-mentioned cold-producing medium can be R134a, R22, R407C, R404A, R410a, R32 etc.Package 1 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 pipe 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 two pass evaprator 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:
A kind of two pass evaprator refrigerant side distributor; The structure of said two pass evaprator: package; The one of which end is the refrigerant side of evaporimeter, and the refrigerant side is provided with adjacent refrigerant inlet and refrigerant outlet, between refrigerant inlet and the refrigerant outlet by running through in the package and the heat exchanger tube that turns back of turning is communicated with; The housing parts of package is provided with two refrigerating medium connectors, it is characterized in that:
The tube sheet place that said heat exchanger tube is in refrigerant side one end is provided with expand tube, and the housing contact site of expand tube and package is tightly connected;
The outside of said expand tube is provided with a dome shape end socket that diameter is identical with expand tube, and said refrigerant inlet and refrigerant outlet place the outside of end socket;
Said distributor is located between the end socket inboard and the expand tube outside, and it is a plectane that is provided with several even distribution through holes, and the plectane diameter is identical with the expand tube diameter, said end socket inboard, distributor and expand tube outside three's edge sealing and fixing.
Said distributor or metal material, or hard material plastics.
The beneficial effect of the utility model:
Distributor in the utility model is owing to be mounted in the refrigerant side expand tube of two pass evaprator; Do not take other space; Distributor is provided with equally distributed through hole, and the cold-producing medium that gets in the evaporimeter heat exchanger tube can be moved by stream with uniform distribution, makes evaporimeter reach best heat exchange effect.This distributor is 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.
Description of drawings
Fig. 1 is existing two pass evaprator structural representation;
Fig. 2 is the two pass evaprator structural representation of the utility model.
