Abstract

Water tank structure of heat pump water heater consists of a metal inner wall of water tank, and a thermal insulation layer. A metal condensing coil of the heat pump system is arranged in the water tank, at the side or the end of which the coil is provided with an opening. The condensing coil directly extends out of the water tank wall and is packed with an insulating layer in the inner wall of the water tank and the heat insulation layer. Two flanges are arranged in the insulating layer, with one flange wedged in the inner wall and the other flange is screwed in the welding flange. Between the two flanges is a seal O-shaped circle which covers the insulating packing layer; and the two can be an entity. The heat exchanging pipe in the water outlet tank is not provided with any joints, so that the heat exchanging pipe has enough intensity to bear the working pressure of the heat pump. The end of the heat exchanging device extends out of the water outlet tank or the joint surrounding has enough space, which is convenient for connection.

Description

The cisten mechanism of Teat pump boiler

One, technical field

The utility model relates to a kind of water tank with heat exchanger, the especially cisten mechanism of Teat pump boiler.

Two, background technology

The Energy Efficiency Ratio of working under the condition of common room temperature of Teat pump boiler is more than 3.0, even under subzero 8 degrees centigrade environment, Energy Efficiency Ratio is still about 1.5, the cold of its evaporimeter can also use as air-conditioning cold flow in summer, compare with the common electrical water heater, energy-conservation effect is very remarkable, and more jumbo water heater suits to make, even still can be like this under not increase of power situation, can bring great convenience to life.Applicable to the bigger building of area, also be applicable to the thermal water source of residential central air conditioning.

But cisten mechanism is had relatively high expectations, and should satisfy adiabatic also will the satisfy requirement of pressure-bearing and the requirement of adapter, and especially the pipeline of cold-producing medium circulation and the fit structure of water tank also will satisfy the electrochemical protection to the water tank metal inner surface simultaneously.As-Is is: because the restriction of process conditions, the necessary excessive joint of adjunction of the water tank pipe interface of heat pump water heater could be connected with heat pump at present, and reliability and security are difficult to be guaranteed like this.Chinese patent 00251344.7 relates to a kind of cisten mechanism of solar water heater, comprise the thermal-collecting tube connecting hole, it is the circular hole on tank floor, with the annular inner edge of circular hole, constitute the identical thermal-collecting tube connecting hole of its two ends shape along the flange of digging to the circular hole periphery with the end of inner edge to the casing in-draw.When this connecting hole contacts with rubber seal, make it stressed evenly, improve sealing effectiveness, increase the service life.This adapter can not be directly used in the refrigeration working fluid of Teat pump boiler.

Three, summary of the invention

The purpose of this utility model is: provide a kind of satisfied thermal insulation also will satisfy the requirement of pressure-bearing and the requirement of adapter, especially the structure that is connected and cooperates with water tank with the pipeline of cold-producing medium circulation also will satisfy the electrochemical protection to the water tank metal inner surface simultaneously.The purpose of this utility model also be to provide a kind of condenser coil in water tank, the water tank of Teat pump boiler that process conditions are good, easy to prepare, condenser coil is again simultaneously that the condensation end of heat pump circulation is a release end of heat, and condenser coil can directly insert heat pump.

The purpose of this utility model is achieved in that the cisten mechanism of Teat pump boiler, comprise that metal water tank inwall and heat-insulation layer constitute, be provided with the metal condensation coil pipe of heat pump in the water tank, coil pipe is provided with opening at water tank sidewall or end, it is characterized in that condenser coil directly stretches out water tank wall, condenser coil is provided with the insulation integument at tank inner wall and thermal insulation layer place, establishing two flanges simultaneously is enclosed within on the insulating barrier, wherein the welding of a slice flange is gone up on the inwall, another sheet flange is screwed onto on the welded flange, be provided with sealing O shape circle between two flanges, on this O shape snare insulation integument, O shape circle can also be integrated with the insulation integument.

Also be provided with water inlet pipe and water outlet pipe in the water tank, electrochemistry metal coating electrode generally inserts inner core with magnesium or magnesium alloy bar, to protect the metal inner core not by chemical attack.

Going out pipe and can adopting mode commonly used with being connected of heat pump of water tank expanded into the connection of horn mouth plus-pressure screw as brazing, metal tube link, also can be in the connection sealing of interface addition polymerization tetrafluoro packing ring etc.

O shape circle can also integral structure available silicon rubber or polytetrafluoroethylmaterial material formation with the insulation integument.

Characteristics of the present utility model are:

1, the heat exchanger pipeline does not have any joint in the water tank, so that the heat exchanger pipeline has sufficient intensity to bear the operating pressure of heat pump.

2, structural particularity.Outside or interface that the port of heat exchanger stretches out water tank have enough big space on every side, are convenient to connect.The mounting means of heat exchanger can be Fig. 1, Fig. 2, Fig. 3 etc.

3, outside connection can be adopted the pipeline connecting mode of common air-conditioning, as welding, crimping etc.

In order to prevent that hydraulic pressure is released the condenser coil heat exchanger in the courage in the water tank courage, adopt thrust structure as Fig. 4 (installing thrust back-up ring or baffle plate additional) or Fig. 5 (the eccentric installation).
