Electric calorifie installation
The utility model belongs to warmer field, mainly refers to a kind of electric calorifie installation.
Heating radiator mainly plays the conduction of heat of heat radiation, and when the heating agent that temperature is higher flows through in heating radiator, the heat entrained by heating agent constantly passes to the lower object of temperature by heating radiator, thus realizes the temperature difference transmission of heat energy.Traditional heat-dissipating sheet is all a series, and the laminated structure that multiple volume is larger is one-body molded, is fixedly connected with, inconvenience is installed, just in case there is partial destruction wholely to replace, increases, reduce and maintenance, all inconvenient, cost is also high, causes the wasting of resources to a certain extent.And the louvre in prior art on fin is much square, square opening is in air circulation process, and its rotation angle position easily produces eddy current, is unfavorable for air circulation.
Utility model content
The utility model provides a kind of electric calorifie installation, and be sleeved on electrothermal tube by multiple independently fin and realize heat radiation, heating efficiency is high, and dismounting is keeped in repair and replaced all very convenient, and this device can be used alone, and also can be arranged on other heating systems.
The technical solution of the utility model: a kind of electric calorifie installation, comprise electrothermal tube, it is characterized in that: described electric calorifie installation also comprises the fin be socketed on electrothermal tube, described heat sink body is the sheet metal of plane, two symmetrical sides of described main body are provided with flange, have through hole in the middle part of main body and through hole is provided with flange, described flange direction is contrary with flange direction, and described fin is socketed on electrothermal tube by this through hole.Adopt between adjacent two fin of this set and form an areola, be convenient to calorie spread, also determine the distance between two fin.
Preferably, the turnover angle of described flange and main body is 90 degree.This angle is convenient to the distance of accurately locating between two fin.
Preferably, the height of described flange is lower than the height of main body.Such setting provides the breach of a crossflow circulation, is namely convenient to the airflow with electrothermal tube vertical direction, improves the speed of hot gas circulation heat radiation.
Preferably, described main body is provided with slotted hole, and slotted hole is located at the vertical direction of two flange, and is positioned at flange top.Slotted hole plays the thermolysis along electrothermal tube axial direction, namely flows to opposite side from the side hot gas of main body by slotted hole, also for being installed to location during electrothermal tube, is convenient to the setting angle determining multiple fin.
Preferably, the length position of described slotted hole is 1/3 of main body transverse width.Arrange like this and the stress of main body in flange both sides can be avoided to concentrate.
Preferably, described flange is provided with stopper slot.Because fin is for be socketed on electrothermal tube one by one, the setting of stopper slot improves the installation fastness of fin and electrothermal tube more, avoids mutually sliding between fin and electrothermal tube.

Detailed description of the invention
As shown in Figure 1-2, electric calorifie installation comprises electrothermal tube 7 and fin 8, and fin 8 comprises the main body 1 of sheet metal construction, has through hole 2 in the middle part of main body, and through hole edge is provided with flange 3, and main body both sides are also provided with flange 4, and the direction of flange 4 is contrary with the direction of flange 3.Multiple fin is installed on electrothermal tube 7 by the socket of this through hole 7, realizes heating heat radiation.Can determine the distance of two panels fin on electrothermal tube in conjunction with the length of flange 3 and the length of flange 4, the electrothermal tube diameter that through hole and flange bore are greater than fin installation just can be socketed on electrothermal tube.
The turnover angle [alpha] of flange and main body is preferably 0-90 degree, and the best is 90 degree.The height H 2 of flange is better lower than the height H 1 of main body, can provide one with the heat dissipation channel of the axial vertical direction of electrothermal tube.Preferably, the length L2 of flange equals the length L1 of flange, is conducive to the distance between two-way positioning fin like this.
Main body 1 can also arrange slotted hole 5, slotted hole is positioned at flange top position, and the direction, position in main body of slotted hole is vertical with main body upper overturning position, and the fluid along electrothermal tube axis after being beneficial to installation circulates, adopt structure instead of the traditional square of slotted hole, reduce flow-disturbing.Flange 3 can also arrange stopper slot 6, strengthen the fastness that fin and electrothermal tube are installed.Preferably, the width L3 of slotted hole equals 1/3 of the transverse width L4 of main body.
Be more than preferred embodiment of the present utility model, and be not used in restriction scope of the present utility model, the suitable improvement that those skilled in the art make according to this thinking also should be considered as protection domain of the present utility model.
