The technical scheme in the invention for solving the above technical problem is: the heat(ing) coil of this wall hanging type heat pump unit, comprise water tank, inner bag and coil pipe, described inner bag is fixed in water tank, described inner bag cylindrically, and inner bag horizontally set, it is characterized in that: described coil pipe comprises an inlet tube, one outlet, some arc tubes and some union elbows for being connected adjacent two arc tubes, connected successively by union elbow head and the tail between described arc tube, parallel arrangement between described arc tube, described inlet tube and outlet are connected with the arc tube of both sides outermost end respectively, described water tank is provided with inlet union and outlet connection, described inlet tube and inlet union are fixed, described outlet and outlet connection are fixed, central angle corresponding to described arc tube is 90 degree to 180 degree, described arc tube is positioned at the outside of inner bag and arc tube is fitted in the bottom of inner bag.During installation, coil pipe is connected and fixed with the inlet union on water tank and outlet connection respectively by the inlet tube at two ends and outlet pipe, now, bottom the arc section meeting automatic attaching to inner bag of coil pipe, it is shaping that coil pipe can realize batch, can not affect it and install, install very convenient; Arc tube is arranged on bottom inner bag, relatively hot water can continue to rise, and the water that to be temperature all the time relatively low of the water bottom inner bag, thus the water that coil pipe is only relatively low to inner bag bottom temp conducts heat, make the medium in coil pipe and the water temperature difference bottom inner bag comparatively large, its heat transfer efficiency is higher.
Preferably, the central angle corresponding to arc tube described in the utility model is 120 degree.
Preferably, the cross section of arc tube described in the utility model is circular, fills heat-conducting glue in the gap between described arc tube and inner bladder outer wall.
Preferably, coil pipe described in the utility model is integral type structure.
Preferably, water tank described in the utility model is provided with water inlet pipe and outlet pipe, and described water inlet pipe is all communicated with inner bag with outlet pipe.
The utility model compared with prior art, have the following advantages and effect: structure is simple, reasonable in design, during installation, coil pipe is connected and fixed with the inlet union on water tank and outlet connection respectively by the inlet tube at two ends and water outlet, now, bottom the arc section meeting automatic attaching to inner bag of coil pipe, it is shaping that coil pipe can realize batch, can not affect it and install, install very convenient; Arc tube is arranged on bottom inner bag, relatively hot water can continue to rise, and the water that to be temperature all the time relatively low of the water bottom inner bag, thus the water that coil pipe is only relatively low to inner bag bottom temp conducts heat, make the medium in coil pipe and the water temperature difference bottom inner bag comparatively large, its heat transfer efficiency is higher.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
Embodiment.
See Fig. 1 to Fig. 4, the heat(ing) coil of the wall hanging type heat pump unit in the present embodiment comprises water tank 1, inner bag 2 and coil pipe 3.
Inner bag 2 in the present embodiment is fixed in water tank 1, and cylindrically, and inner bag 2 horizontally set, even if the used time, to inner bag 2 inner bag 2 laterally place.
Coil pipe 3 in the present embodiment comprises an inlet tube 31, one outlet 32, some arc tubes 33 and some union elbows 34 for being connected adjacent two arc tubes 33, connected successively by union elbow 34 head and the tail between arc tube 33, parallel arrangement between arc tube 33, inlet tube 31 and outlet 32 are connected with the arc tube 33 of both sides outermost end respectively, water tank 1 is provided with inlet union 11 and outlet connection 12, inlet tube 31 is fixed with inlet union 11, outlet 32 is fixed with outlet connection 12, just the installation of coil pipe 3 is completed thus, central angle a corresponding to arc tube 33 is 90 degree to 180 degree, arc tube 33 is positioned at the outside of inner bag 2 and arc tube 33 is fitted in the bottom of inner bag 2, compared to existing technology, coil pipe 3 only heats the bottom of inner bag 2, instead of to the heating of inner bag 2 entirety, thus material is saved, reduce cost.
During installation, coil pipe 3 is connected and fixed with the inlet union 11 on water tank 1 and outlet connection 12 respectively by the inlet tube 31 at two ends and outlet pipe 32, now, bottom the arc section 33 meeting automatic attaching to inner bag 2 of coil pipe 3, it is shaping that coil pipe 3 can realize batch, can not affect it and install, need not as prior art, straight tube is detoured on inner bag 2 and form coil pipe, install very convenient; Arc tube 33 is arranged on bottom inner bag 2, relatively hot water can continue to rise, and the water that to be temperature all the time relatively low of the water bottom inner bag 2, thus the water that coil pipe 3 is only relatively low to inner bag 2 bottom temp conducts heat, make the water temperature bottom the medium in coil pipe 3 and inner bag 2 keep maximum, thus its heat transfer efficiency is higher.
Union elbow 34 in the present embodiment is also arc shape, makes on its outer wall that can be fitted in inner bag 2, thus coil pipe 3 is fully contacted with inner bag 2, increases the efficiency of heating surface further.
The central angle a corresponding to arc tube 33 in the present embodiment is 120 degree, the shape of arc tube 33 is mated with the external diameter of inner bag 2, thus arc tube 33 and inner bag 2 outer wall can be made fully to fit, central angle a is 120 degree of results being long-term experiment and drawing, when central angle a is 120 degree, when ensureing the efficiency of heating surface to inner bag 2, the saving material cost of maximizing.
The cross section of the arc tube 33 in the present embodiment is circular, after arc tube 33 and inner bag 2 are fitted, heat-conducting glue 35 is filled in gap between arc tube 33 and inner bag 2 outer wall, thus arc tube 33 and inner bag 2 heat transfer area can be increased, improve its efficiency of heating surface, heat-conducting glue 35 also plays reinforcement effect to coil pipe 3, increases the bonding strength between coil pipe 3 and inner bag 2.
Coil pipe 3 in the present embodiment is integral type structure, and coil pipe 3 can carry out shaping in advance in batches, directly uses, can improve installation effectiveness during installation.
Water tank 1 in the present embodiment is provided with water inlet pipe 13 and outlet pipe 14, and water inlet pipe 13 is all communicated with inner bag 2 with outlet pipe 14, for supplying water to inner bag 2 and discharge water.
In addition, it should be noted that, the specific embodiment described in this description, the shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this description is only to the utility model structure and the explanation of accompanying drawing example.The equivalence change that structure, feature and principle described in all foundation the utility model inventional idea are done or simple change, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
