Description
Technical field
The present invention relates to the heater field, be specifically related to heat sink strip.
Background technology
The electric heating organ pipe is widely used in fields such as small-sized electric heater, air-conditioning, auto heater, aircraft heater, train heater, heater peculiar to vessel.
Yet the heat sink strip on the conventional electric heating organ pipe is to adopt soldering to connect basically, perhaps sticks with glue knot.Electric heating organ pipe and heat sink strip connected mode in the existing PTC electric heater normally adopt gluing mode.Adopt gluing mode not only can in the heater heats process, produce glue flavor or a spot of organic gas, also may be after long-time the use, it is loosening to make that heat sink strip and electric heating organ pipe produce, and reduces the useful life of heater.
When being especially in use in the middle of the air-conditioning, the problems referred to above are more outstanding.In recent years, the raising of Along with people's quality of life, air-conditioning is popularized gradually.As far as air-conditioning, the electric heating organ pipe not only plays the auxiliary effect that heats, and when temperature is low, such as being lower than subzero 5 when spending, can play the effect to the refrigerating fluid preheating, makes air-conditioning can obtain at low temperatures to start.Air-conditioning generally is used for being freezed in the space of relative closure, perhaps heating, and access times are frequent, service time is long.Therefore the glue flavor or the organic gas that distribute are accumulated easily, are unfavorable for health.
Summary of the invention
The object of the present invention is to provide to be applicable to and to be pressed abd fixed on PTC electric heating organ pipe heat sink strip, solve above technical problem.
The technical problem that the present invention solved can adopt following technical scheme to realize:
Be applicable to and be pressed abd fixed on PTC electric heating organ pipe heat sink strip; Comprise that one is used to be placed on the fin on the PTC electric heating organ pipe; It is characterized in that; The part at middle part, said fin the place ahead upwards is bent to form a tilted metallic sheet, and said fin rear maintenance level forms a transverse metal sheet, and two of the part maintenance level formation that said fin is positioned at said tilted metallic sheet both sides compress sheet metal;
The tilted metallic sheet other end of said fin connects the transverse metal sheet rear of another fin, and at least two said fin are in turn connected to form a heat radiating metal bar, and the direction of adjacent two said tilted metallic sheets is opposite;
The said length that compresses sheet metal equals the longest distance between adjacent two said tilted metallic sheets;
Said heat radiating metal bar top is coated with the fixing metal sheet of fixation together, and the said fixing metal sheet left and right sides is respectively equipped with flange, and two said flange tighten the said sheet metal that compresses of both sides respectively.
Said fixing metal sheet adopts U type aluminium sheet, so that be fixed on the said fin.
Be positioned at two of said tilted metallic sheet two side portions maintenance level formation at said fin and compress sheet metal.So that the flange unification of U type aluminium sheet is fixed.When the compressing sheet metal and be horizontally disposed with of at least two said fin, as long as U type aluminium sheet one side is provided with long flange, just all that can fix a side compress sheet metal.Two flange through both sides can make the heat sink strip overall structure obtain fixing preferably.
And with the said longest distance of length setting between adjacent two said tilted metallic sheets that compresses sheet metal so that with two adjacent said fin connect tightr, make that said heat radiating metal bar is more firm, so that increase the useful life of air conditioner.Be positioned at the sheet metal that compresses of below, be used for being pressed abd fixed on the body that PTC electric heating organ pipe heat sink strip is fixed on PTC electric heating organ pipe being applicable to.
The present invention on the make adopts roll extrusion or stamping technology to carry out roll extrusion or punching press; One whole said heat radiating metal bar is carried out roll extrusion or punching press; With its roll extrusion or strike out the said fin that each links to each other; One of them said fin is minimum in a whole said heat radiating metal bar cell, and rammed said heat radiating metal bar can be found out the heat radiating metal bar of forming for the sheet metal of several ladder type shapes from the side.When PTC electric heating organ pipe is longer, can or stamp out the suitable heat radiating metal bar of length according to the length roll extrusion of PTC electric heating organ pipe, so that can just in time be applicable to the length of PTC electric heating organ pipe.Therefore, adopt the heat radiating metal bar of roll extrusion or stamping technology roll extrusion or punching press to carry out roll extrusion or punching press, to be applicable to the PTC electric heating organ pipe of various different lengths according to the length of the PTC electric heating organ pipe in using.Through the said heat radiating metal bar of roll extrusion or stamping technology, dimensional accuracy is more accurate, and each junction is not easy to fracture, and lead tolerance is few, and compliance with environmental protection requirements has guaranteed that further people's is healthy.
The said width that compresses sheet metal equals width difference half the of width and the said tilted metallic sheet of said transverse metal sheet.
The width of said transverse metal sheet is 11.0mm～20.0mm.Be preferably 15.0mm.
The said width that compresses sheet metal is 1.0mm～4.0mm.Be preferably 2.0mm.
The said length that compresses sheet metal is 1.0mm～5.0mm, is preferably 3.8mm.
Angle between said transverse metal sheet and the said tilted metallic sheet is 115 degree～125 degree, is preferably 120 degree.
The length of said transverse metal sheet is 1.0mm～5.0mm, is preferably 2.2mm.
The height of said heat radiating metal bar is 5.0mm～15.0mm, is preferably 9.0mm.So that bring into play the maximum effect of said heat radiating metal bar.
The heat radiating metal bar that said heat radiating metal strip adoption aluminum is made.The heat radiating metal bar of aluminum has good heat-conducting, oxidative resistance, so that improve the thermal diffusivity of said heat radiating metal bar, and the useful life that increases the heat radiating metal bar.
Beneficial effect: owing to adopted technique scheme, the present invention to have characteristics such as simple in structure, that production cost is low.And since the present invention with the mode of roll extrusion or punching press with an entire heat dissipation bonding jumper; Roll extrusion or strike out the fin that is fixed on each connection on the PTC electric heating organ pipe; The life-span of using is longer, is convenient to be fixed on the PTC electric heating organ pipe, also is applicable to the PTC electric heating organ pipe of different length.And because do not need welding, avoided the leaded problem that causes because of scolder, reduced the healthy possibility of harm people.Do not adopt glue bond, eliminated the problem that is easy to generate the glue flavor in the heating process.
