Abstract
The utility model relates to a heat exchanger with spray and automatic-descaling functions, which comprises a water tank, a water inlet pipe, a water outlet pipe, a cooling medium inlet pipe, a cooling medium outlet pipe and a heat-exchange tube. Four partitions are arranged at a certain distance inside the water tank to divide the water tank, from top to bottom, into a first cooling medium chamber, an inlet water chamber, a heat-exchange chamber, an outlet water chamber and a second cooling medium chamber in order. The water inlet pipe and the water outlet pipe respectively communicate with the inlet water chamber and the outlet water chamber. The heat-exchange tube penetrates the partitions in order and the entrance and the exit of the heat-exchange tube respectively communicate with the first cooling medium chamber and the second cooling medium chamber. A water inlet hole is formed on the partition between the inlet water chamber and the heat-exchange chamber. A water outlet hole is formed on the partition between the heat-exchange chamber and the outlet water chamber. When the heat exchanger works, the water flows through the water holes and then is uniformly sprayed onto the outer surface of the heat-exchange tube inside the heat-exchange chamber, so as to ensure the complete and uniform contact between the water and the surface of the heat-exchange tube. Additionally, the spray impact allows the water to generate the turbulent flow, thereby increasing the heat-exchange efficiency.
Description
Technical field
The invention belongs to the technical field of air-source water heater, relate in particular to a kind of spraying automatic descaling heat exchanger, this heat exchanger is used for air-source water heater.
Background technology
Along with constant development of economy, energy shortage and pollution problem are serious day by day, energy-conservation and environmental protection has become modern economy development main flow, the characteristics of the energy-conservation and environmental protection that heat pump techniques has owing to himself come into one's own, Teat pump boiler is exactly a kind of New-type water heater that utilizes the heat pump principle exploitation, operation principle is as follows: the cold media gas of compressor discharge HTHP enters water fluorine heat exchanger during (seeing accompanying drawing 7) machine works, with the cold water generation heat exchange in the heat exchanger, cold water is heated into hot water offers the user, the refrigerant liquid of warm high pressure during self is cooled to, the liquid that becomes low-temp low-pressure through the choke valve throttling absorbs airborne heat of vaporization in evaporimeter be that the gas of low-temp low-pressure is sucked again the gas of boil down to HTHP by compressor and finishes a circulation, so reaches the purpose that hot water is provided repeatedly.But referenced patent number is the Chinese utility model patent " heating circulation system of air energy heat pump " of ZL200520038847.5 (notification number is CN2767925Y).
This shows that heat exchanger is very important element in the heat pump, it is serving as the directly function of heat hot water, and its heat exchange efficiency has directly influenced the efficient of machine.
Existing heat exchanger mainly contains two kinds of bushing type and plate type heat exchangers, and bushing type is to adopt copper tube outside cover steel pipe, walks refrigerant in the copper tube, and leaking water in the outside, curves coil form then and form (seeing accompanying drawing 8).Be a kind of air-source water heater the Chinese utility model patent " air-source water heater " of ZL200310109863.4 (notification number is CN1556353Y) has disclosed also as a patent No., by being connected with electric controller, in the shell of computer control panel, be installed with heater, by water pipe be connected with water tank form, also comprise fixing blower fan in the enclosure, described heater is connected with the inlet of flow controller by connector by the liquid outlet of heat collector, the liquid outlet of flow controller is connected with the inlet of heat exchanger, the liquid outlet of heat exchanger is connected with the inlet of compressor, the integral body that the one or more thermodynamic cycle loop that the liquid outlet of compressor and the inlet of heat collector connect and compose is formed; Described heat collector is fixed with heat-exchanger rig and forms by in the staving that has heat-insulation layer.The general development size of this double pipe heat exchanger is long, tube wall is thicker, and current belong to laminar condition, so efficient is lower.
Plate type heat exchanger is formed (seeing accompanying drawing 9) by the concavo-convex stainless steel of drawing, the chevron concave convex texture of two adjacent plates becomes the opposite combination of 180 degree, therefore concavo-convex crestal line forms staggered contact point between two plates, with contact point with vacuum welding in conjunction with after just constitute the interlaced flow passage of heat exchanger, wherein one sidle the refrigerant opposite side and leak water, this heat exchanger can be accomplished miniaturization and, but owing to be to adopt drawing, its runner is generally all narrow, be easy to result in blockage, the weld high-voltage resistance capability is also poor in addition.
Also have; no matter be which kind of heat exchanger; owing to all contact for a long time with hot water; and calcium ion etc. is arranged in the water; therefore be easy to form incrustation scale at heat exchanger surface; the main component of incrustation scale is a calcium carbonate; it is the non-conductor of heat; so long heat exchange surface of time one will be enclosed one deck incrustation scale; influence the heat exchange efficiency of heat exchanger; when serious even can stop up runner; existing these two kinds of heat exchangers all are the solutions of adopting this chemical method of pickling, promptly adopt weak acid to circulate in heat exchanger after machine uses a period of time, utilize acid and incrustation scale generation chemical reaction to reach the purpose of scale removal; so this mode must be could implement after shutting down; reduced the service efficiency of machine, simultaneously because acid all has corrosiveness to copper or iron, so that this method operates is very inconvenient; if it is misoperation also can damage by the heat exchanging device, serious even can cause scrapping of heat exchanger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of heat exchanger effectiveness high heat exchanger at above-mentioned prior art present situation, has reasonable in design, the sufficient advantage of heat exchange.
Second technical problem to be solved by this invention provides a kind ofly has the pickling of need not and the heat exchanger of automatically descaling function.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of spraying automatic descaling heat exchanger, include storage tank, be inserted with water inlet pipe, outlet pipe, refrigerant inlet pipe and refrigerant on the storage tank and go out pipe, be provided with the heat exchanger tube that the cooling matchmaker is flowed in the storage tank within it; It is characterized in that: be arranged at intervals with four dividing plates in the described storage tank, and storage tank is divided into the first refrigerant chamber, intake antrum, heat exchanging chamber, water chamber and the second refrigerant chamber from top to bottom successively; Described water inlet pipe and outlet pipe communicate with intake antrum and water chamber respectively, and described refrigerant inlet pipe and refrigerant go out pipe and communicate with the first refrigerant chamber and the second refrigerant chamber respectively; Described heat exchanger tube passes each dividing plate successively, and the import of heat exchanger tube communicates with the first refrigerant chamber and the second refrigerant chamber respectively with outlet; Have on the dividing plate between described intake antrum and the heat exchanging chamber and can make the inlet opening of cold water, have apopore on the dividing plate between described heat exchanging chamber and the water chamber towards the heat exchanger tube spray.
