A kind of improved electric heating installation using oil as medium that provides according to the utility model, comprise that the fin, that multi-disc is connected in turn is installed in the electric cabinet on the described fin and is installed in the interior calandria of described fin, described electric cabinet is provided with switch, thermosistor, thermal protector and cable; Described fin is the plates of hollow, its inside forms oil guide groove, the upper/lower terminal moulding of described fin or the joint sleeve that along continuous straight runs extends is installed, be provided with the oil guiding hole that communicates with described oil guide groove in the described joint sleeve, joint sleeve on each described fin interconnects, and forms an airtight oil pocket, is filled with in it to add deep fat, the periphery of described fin bends inwards, and forms a circular fold.

A kind of improved electric heating installation using oil as medium that provides according to the utility model also has following attached technical characterictic:

Be formed with many louvres on the top flap of described fin.

Described louvre is a bar hole.

Described flanging and described heat sink body are perpendicular.

Continue to bend inwards in the top of described flanging, camber shape or semicircle shape.

Described fin is covered by two cover plates and forms, and wherein a slice cover plate forms described flanging, and another sheet cover plate covers in forming the cover plate of flanging.

The width of described flanging is less than half of described connection pipe box length.

A kind of improved electric heating installation using oil as medium that provides according to the utility model compared with prior art has following advantage: at first, fin periphery of the present utility model all forms flanging, and flanging surrounds annular shape, therefore, it has higher intensity, is difficult for deforming, and whole better appearance; Secondly, because the top and the bottom of fin all form flanging, therefore, it is suitable for being applied to open electric heating installation using oil as medium; Once more, the flanging at fin top forms the bar shaped louvre, is beneficial to fin and dispels the heat; At last, bending is continued at the flanging top of fin, and camber or semicircle further strengthen the intensity of the flanging of fin, make it be difficult for deforming, and is beneficial to transportation and uses.

The specific embodiment

Referring to Fig. 1, a kind of preferred embodiment that provides according to the utility model, comprise that fin 1, that multi-disc is connected in turn is installed in the electric cabinet 2 on the described fin 1 and is installed in calandria in the described fin 2, the calandria in the utility model adopts electric heating tube.Described electric cabinet 2 is installed in the side of described fin 1, forms many louvres 20 on the described electric cabinet 2, and the hot gas of described fin 1 and described electric cabinet 2 junctions distributes by described louvre 20.Effectively reduce the temperature in the described electric cabinet 2, described electric cabinet 2 is played the effect of protection.The bottom of described fin 1 is equipped with roller 4, and described roller 4 is beneficial to moving and using of electric heating installation using oil as medium.Described electric cabinet 2 is provided with switch, thermosistor, thermal protector and cable; Described cable is used to connect power supply, and described switch is used to control cutting out of power supply, and described thermosistor is used to regulate the temperature of electric heating installation using oil as medium.Described thermal protector can play the effect of overtemperature protection, and when electric heating installation using oil as medium surpassed the temperature of setting, described thermal protector can be cut off the electricity supply.These technology belong to the prior art of comparative maturity, therefore, repeat no more herein.Referring to Fig. 2, Fig. 3 and Fig. 5, described fin 1 is the plates of hollow, its inside forms oil guide groove 11, the upper/lower terminal moulding of described the fin 1 or joint sleeve 12 that along continuous straight runs extends is installed, be provided with the oil guiding hole that communicates with described oil guide groove 11 in the described joint sleeve 12, joint sleeve 12 on each described fin 1 interconnects, and forms an airtight oil pocket, is filled with in it to add deep fat.Among the embodiment that the utility model provides, described fin 1 and described joint sleeve 12 are one-body molded.The joint sleeve 12 of each fin 1 welds together, thereby forms a monoblock type heat sink assembly.

Referring to Fig. 2, Fig. 4 to Fig. 6, the utility model mainly is that the periphery at fin 1 carries out flanging and handles, and the periphery of described fin 1 is bent inwards, and forms a circular fold 3.Described flanging 3 is perpendicular with described fin 1 body.Such flanging 3 has higher intensity, and is not yielding.Secondly, the flanging with this structure makes the whole better appearance of electric heating installation using oil as medium.
