Description
Technical field
The utility model relates to technical field of electric appliances, particularly a kind of circulation heat exchanger.
Background technology
In the refrigeration plant such as refrigerator, refrigerator-freezer, need to use heat exchanger and realize refrigeration, the cold-producing medium circulating conducts heat to heat exchanger, the metal fin of heat exchanger distributes to air, then by blower fan by the hot-air heat exchanger that blows off, realize hot-swap feature.Because electrical equipment inner space is narrow and small, for the consideration of compression volume, heat exchanger is fit in electrical equipment after being often folded into three-dimensional bulk again.Yet three-dimensional heat exchanger brings adverse effect to rate of heat exchange, primary air that blower fan provides can be directly through heat exchanger, contacts insufficiently with heat exchanger, causes overall thermal exchange rate not high.
Summary of the invention
The technical problems to be solved in the utility model be how to solve existing stereo structure heat exchanger contact with cooling blast insufficient, the problem that rate of heat exchange is not high.
For solving the problems of the technologies described above, the utility model provides a kind of circulation heat exchanger, comprising: finned tube and fixed support, described finned tube multiple row is arranged in parallel, and be folded into be with ring porous three-dimensional block; Described fixed support and described finned tube are fixed, and finned tube described in multiple row is unified; On described finned tube, be also provided with deep bead, described deep bead is covered on described annular distance, and described annular distance is blocked in whole or in part.
Preferably, one group of described deep bead or two groups of opposite side are provided with the connecting plate with installing hole, and described connecting plate is connected with described fixed support bolt.
Preferably, the surrounding of described deep bead is provided with L shaped card adapter plate, and described card adapter plate is with U-lag, and described finned tube includes condenser pipe, and described card adapter plate is by described U-lag and described condenser pipe clamping.
Preferably, the surrounding of described deep bead is provided with fixed-wing, and described finned tube includes fin, and described fixed-wing and fin are fixed by welding manner.
This circulation heat exchanger by covering deep bead on the annular distance of ring-shaped finned tube, the air-flow that blower fan brings is entered from whole heat exchanger one side, after doing heat exchange, heat exchanger flows out from opposite side, deep bead 4 can avoid air-flow to flow through from centre without the region of heat exchanger tube and fin, force air-flow completely through there being the portion of heat exchanger tube and fin, thereby make air flow stream cross whole heat exchanger to obtain abundant heat radiation, heat exchange efficiency can improve 10% left and right.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The first embodiment of the present utility model as shown in Figure 1 to Figure 2, comprising: finned tube 1 and fixed support 2, and finned tube 1 multiple row is arranged in parallel, and is folded into the solid of annular distance 3 blockly, and finned tube 1 comprises condenser pipe 101, is wound with fin 102 on it.Fixed support 2 is fixing with finned tube 1, and multiple row finned tube 1 is unified.The air-flow that this configuration state blowing down blower fan brings will mainly pass from annular distance 3, and heat exchanger only has the condenser pipe 101 of annular distance 3 peripheries can efficiently radiates heat.
Deep bead 4 is covered on annular distance 3, and the edge of the edge of deep bead 4 and annular distance 3 leaves gap, and gap length, at 10 ~ 20mm, makes part air-flow can enter annular distance 3.The structure of deep bead 4 is and the thin slice of annular distance 3 adaptations, is respectively equipped with the connecting plate 401 with installing hole on one group opposite side, and connecting plate 401 is fixing by bolt and fixed support 2.
When this circulation heat exchanger work, the air-flow that blower fan brings enters from whole heat exchanger one side, after doing heat exchange, heat exchanger flows out from opposite side, deep bead 4 can avoid air-flow to flow through from centre without the region of heat exchanger tube and fin, force air-flow completely through there being the portion of heat exchanger tube and fin, thereby make air flow stream cross whole heat exchanger to obtain abundant heat radiation, heat exchange efficiency can improve 10% left and right.
The second embodiment as shown in Figures 3 to 5, the surrounding of fluid dividing cover 4 is provided with L shaped card adapter plate 402, and card adapter plate 402 is with the Baltimore groove 403 of U-shaped, and Baltimore groove 403 is connected with condenser pipe 101 clampings, deep bead 4 is obtained fixing.
The third embodiment as shown in Figure 6 and Figure 7, the surrounding of deep bead 4 is provided with fixed-wing 404, and fixed-wing 404 inserts in fin 102, and is welded and fixed.Fin 102 is spirally wound on condenser pipe 101, thereby fixed-wing 404 can be fixed.
Above embodiment is only for illustrating the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
