Technical field
The present invention relates to a kind of heater, specifically refer to heater capable of circulation.
Background technology
Mobile field camp is the on-the-spot indispensable conventional equipment of petroleum exploration and development, is the place of operating worker daily life system and storing tools and other equipment.Mobile field camp can be divided into two large classes by function difference, and field engineering room and life mobile field camp, have more than 30 kind.But, because not belonging to, it is not directly used in the main equipment that exploration and development is produced, mainly play assistant service, so be not subject to too many attention, all structure is simpler for the on-the-spot mobile field camp great majority that use of many petroleum exploration and developments, and technique is more coarse, and function is not strong.
Particularly under cold snap, oil exploration equipment easily under low temperature environment operating efficiency reduce, or even impaired, therefore in mobile field camp, the Insulation of equipment must be perfect, to guarantee the stable of indoor temperature.At present, generally adopt on the market independent strip heater, heating wire is easy under hot environment oxidized and impaired after long-time use, thereby cause, add thermal break, and the power of heater is less, cannot provide reliable guarantee in the insulation that be oil equipment and staff cold season.
Summary of the invention
The object of the present invention is to provide heater capable of circulation, facilitate the insulation of oil exploration equipment in mobile field camp, improve the efficiency of heater.
Object of the present invention is achieved through the following technical solutions:
Heater capable of circulation, comprise housing and two Fans, in housing, be provided with heating chamber, blower fan is placed in the bottom of heating chamber, is provided with air inlet on housing, also comprises baffle plate and a plurality of U-shaped heating tubes that are arranged on heating chamber middle part, described baffle plate is vertically set on the bottom of heating chamber, on the bottom of baffle plate, also have a plurality of pores, described U-shaped heating tube run through baffle plate be arranged at blower fan directly over, the both sides of housing and top are all provided with shutter.When traditional heater utilizes electric-heating-wire-heating, only rely on the heat self producing to external radiation, the efficiency of heating surface is lower, causes temperature in mobile field camp to rise slowly, the present invention, by blower fan being set and improving heater interior layout, utilizes outside air fully to contact with a plurality of U-shaped heating tubes, utilizes the mobility of air, makes the heat producing fast to surrounding radiation under the drive of blower fan, thereby plays the effect of indoor heat insulating, the U-shaped heating tube of installing can make the contact area of air and body increase, can accelerate the radiation of heat, improve the efficiency of heating surface, in heating chamber, lean on into blower fan and the baffle plate of air inlet one side, U-shaped heating tube forms the first heating clamber, air is heated rear portion and gets rid of by the shutter of case top, another part enters into the second heating clamber of another Fans and baffle plate formation, after being heated, continues air to flow in cavity, by the pore on baffle plate, enter again the first heating clamber with together with extraneous air, continuation is circulating-heating in heating chamber, when heating chamber internal pressure reaches certain value, the shutter at housing two ends all starts to discharge in a large number heat, start being incubated processing in mobile field camp, circulating air heat can guarantee that in mobile field camp, heat provides maintenance stable, makes fast indoor air temperature raise, and has also improved family's electrothermal efficiency of heater simultaneously.
Described U-shaped heating tube comprises heating wire, binding post and insulator, heating wire is arranged in U-shaped heating tube, and the two ends of U-shaped heating tube are provided with end socket, and binding post is connected with heating wire through end socket, binding post is connected with external power source, and described insulator is arranged between heating wire and U-shaped heating tube.The present invention is undertaken the air in mobile field camp to heat by a plurality of staggered U-shaped heating tubes are set in housing, make can be for a long time stable at heater its duty of maintenance, and can be because of any heating wire wherein not impaired and stop heating; A plurality of U-shaped heating tubes are arranged in parallel, and by binding post, are connected with external power source, have avoided high temperature to cause heating wire to blow just stopping the phenomenon of heating to occur, and have also improved the job stability of heater simultaneously, have guaranteed the service life that it is permanent.
The direction of rotation of two described blower fans.The blower fan of contrary direction of rotation can make the Air Flow in heating chamber more smooth and easy, guarantees the cyclicity of air heat.
Described insulator is nano aluminum nitride compound silica gel.Traditional megohmite insulant mostly is magnesia powder, but magnesia powder kind is on the market numerous and diverse, quality level is uneven, during heating wire work, be easy to cause heat in U-shaped heating tube to gather, cause the damage of U-shaped heating tube, and the nano silicon nitride aluminium powder that the present invention adopts, thermal coefficient of expansion is little, good with semiconductor silicon matching, there is high heat conduction, good, the resistant to elevated temperatures performance of electrical insulating property, can guarantee that U-shaped heating tube has longer service life.
Described heating wire is nichrome heating wire.Nichrome heating wire intensity in hot environment is high, and long term high temperature operation is not yielding, be difficult for change structure, and the normal temperature plasticity of nichrome heating wire is good, and the reparation after sex change is comparatively simple.In addition, nichrome heating wire radiance is high, and good, the long service life of carrying magnetic, corrosion resistance not contributes to guarantee the job stability of heater.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention's heater capable of circulation, comprise housing, heating wire, binding post and a plurality of being staggered are arranged on the U-shaped heating tube of enclosure interior, on described housing, have a plurality of through holes, heating wire is arranged in U-shaped heating tube, the two ends of U-shaped heating tube are provided with end socket, binding post is connected with heating wire through end socket, binding post is connected with external power source, also comprise insulator and overtemperature protection system, described insulator is arranged between heating wire and U-shaped heating tube, described overtemperature protection system is arranged on the through hole of enclosure interior, and overtemperature protection system is connected with binding post, be arranged on the overtemperature protection system of through hole, when enclosure interior temperature is elevated to maximum, overtemperature protection system just will cut off being connected between U-shaped heating tube and external power source, until temperature recovery is to normal level, external power source continues power supply, and heating wire continues heating, has avoided high temperature to cause the phenomenon that heating wire blows to occur, also the job stability that has improved heater, has guaranteed the service life that it is permanent simultaneously,
