Abstract
The utility model relates to a tube-shell type heat exchange device. The tube-shell type heat exchange device comprises a casing, wherein the casing is provided with first and second ports, at least one group of refrigerant pipeline units are arranged inside the casing, two ends of the refrigerant pipeline units extend out of the casing respectively to form first and second ports, and a throttling device is arranged between the first port of the casing and the refrigerant pipeline second port. The tube-shell type heat exchange device is usually used in a heat pump hot water system to serve as a secondary condenser, during working, a high-temperature refrigerant on the high-pressure side is further cooled by a throttled low-pressure low-temperature refrigerant in the heat exchange device, and the throttled refrigerant is creatively used for cooling the high-pressure high-temperature side of the system, so that the refrigeration condition is improved, and the phenomena of excessive pressure on the high-pressure side and liquid impacts on the low-pressure air-suction side of the heat pump hot water system can be effectively prevented; the normal usage of a heat-pump water heater is guaranteed.
Description
Technical field
The utility model relates to a kind of refrigerating plant, particularly a kind of shell-and-tube heat-exchange device for heat pump.
Background technology
The structure of shell-and-tube exchanger comprises housing, and housing mostly is cylindrical shape, and tube bank is equipped with in inside, and the tube bank two ends are fixed on the tube sheet.Carry out cold and hot two kinds of fluids of heat exchange, a kind of mobile in pipe, be called tube side fluid; Another kind of mobile outside pipe, be called shell-side fluid.Fluid during work in the tube bank is water or unholiness and easy other fluid of fouling normally, and shell-side fluid generally is refrigerant.
Above-mentioned traditional shell-and-tube exchanger structure is widely used in the refrigeration systems such as central air-conditioning.But in the tube side of shell-and-tube exchanger and shell side, use same fluid with the heat pump working method that solves Teat pump boiler high-temperature and high-pressure technique problem concrete those dew in any technical literature not.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides and uses same fluid to solve the heat-exchange device of Teat pump boiler high-temperature and high-pressure technique problem in a kind of tube side at shell-and-tube exchanger and the shell side.
The technical scheme that the utility model adopts is:
A kind of shell-and-tube heat-exchange device, comprise housing, housing is provided with first, second interface, enclosure interior is provided with at least one group of refrigerant pipe unit, the two ends of refrigerant pipe unit are stretched out housing respectively and are formed first, second interface outward, are provided with flow controller between first interface of housing and refrigerant pipe second interface.
Further improvement of the utility model, described flow controller are capillary.
Further improvement of the utility model, described flow controller are expansion valve, can be that heating power expansion valve also can be electric expansion valve.
Further improvement of the utility model, described refrigerant pipe unit is the tube bank runner.
Further improvement of the utility model, described refrigerant pipe unit is the tube sheet runner.
Further improvement of the utility model, described refrigerant pipe unit can adopt helix tube or straight tube design.
The beneficial effects of the utility model are: this shell-and-tube heat-exchange device is generally used in the heat pump hot-water system as after-condenser, on high-tension side high temperature refrigerant is further cooled off by the low-pressure low-temperature refrigerant after the throttling in heat exchanger during work, refrigerant after the creationary employing throttling cools off system self high pressure-temperature side, improved cooling condition, thereby can prevent effectively that the situation of liquid hammer from appearring in the too high or low pressure air suction side of the high side pressure of heat pump hot-water system; Guarantee the normal use of Teat pump boiler.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is shell-and-tube heat-exchange device embodiment 1 structural representation;
Fig. 2 is shell-and-tube heat-exchange device embodiment 2 structural representations.
The specific embodiment
Embodiment 1: with reference to shown in Figure 1, during work, the high pressure-temperature refrigerant that comes out from Teat pump boiler flows into the refrigerant pipe unit from first interface 21 of refrigerant pipe unit 2, form tube side fluid, tube side fluid flows out from second interface 22 of refrigerant pipe unit 2, enter throttling step-down in the flow controller 3, the low-pressure low-temperature refrigerant after throttling enters enclosure interior from housing 1 second interface 11, forms shell-side fluid.In shell-and-tube exchanger, tube side fluid and shell-side fluid are carried out heat exchange, have reduced the temperature of tube side fluid one side refrigerant.Shell-side fluid after heat exchange flows out from housing 1 second interface 12, enters further heat exchange in the evaporimeter of next link or the heat exchanger.
Embodiment 2: with reference to shown in Figure 2, during work, the high pressure-temperature refrigerant that comes out from Teat pump boiler enters enclosure interior from housing 1 second interface 12, form shell-side fluid, shell-side fluid flows out from housing 1 second interface 11, enter throttling step-down in the flow controller 3, the low-pressure low-temperature refrigerant after throttling enters the refrigerant pipe unit from second interface 22 of refrigerant pipe unit 2, forms tube side fluid.In shell-and-tube exchanger, tube side fluid and shell-side fluid are carried out heat exchange, have reduced the temperature of shell-side fluid one side refrigerant.Tube side fluid after heat exchange flows out from first interface 21 of refrigerant pipe unit 2, enters further heat exchange in the evaporimeter of next link or the heat exchanger.
In actual applications, as required, flow controller 3 can be adopted capillary or expansion valve, and expansion valve can be heating power expansion valve, also can be electric expansion valve.And refrigerant pipe unit 2 can adopt tube bank design or spiral-shaped structure, also can adopt the tube sheet flow passage structure.And in order to strengthen the heat exchange effect, spoiler or baffle plate can also be set in housing, also can spoiler or baffle plate be set in the outside or the inboard of refrigerant pipe unit 2.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
