Abstract
The utility model relates to a PTC liquid electric heater, which is used for heating various liquids in industry. The utility model is composed of a casing, a heating element, insulating materials, a power supply, etc. The outermost layer of the utility model is cooling ribs (4), the second layer of the utility model is a stainless steel pipe (3), and residual layers of the utility model are orderly the insulating materials (8), an electric sheet (7), and a PTC electric heating element (5) inwards. Adhesive (6) is evenly coated between the PTC electric heating element (5) and the aluminium electric sheet (7) to make the electric sheet and the PTC electric heating element be connected effectively. The utility model has the advantages of enhanced electricity and heat exchange rate, electric energy saving, rapid response time, fast heat conducting, and long service life. The utility model can be arranged on various liquid containers for heating various static liquids or flowing liquids such as water, petroleum, acid solution, alkali solution, etc. The utility model is suitable for field use.
Description
The utility model relates to a kind of industrial PTC liquid electric heater that is used for heating various liquid.
Existing industrial widely used nickel filament electric tube heater, its temperature adjusting performance is poor, and the electric heating exchange rate is low; At present, the PTC electric heater that domestic-developed is made, mostly be to utilize the PTC electric heating element to make the air heater of various types, make liquid electric heater for utilizing the PTC electric heating element, because heat transfer and the design alternative of heat radiation media are improper, its heating power is difficult to output, has limited its application in liquid heat.
The purpose of this utility model is to provide a kind of PTC liquid electric heater, and its electric heating exchange rate height has constant temperature, temperature regulation characteristic.
Structure of the present utility model is achieved in that it is made up of shell, heating element, insulating material, power line etc., and outermost layer is a fin 4, and the second layer is a stainless steel tube 3, inwardly is insulating material 8, conducting strip 7, bonding agent 6 and PTC electric heating element 5 successively.Stainless steel tube is flat tube, its upper/lower terminal is equipped with upper cover 1 and bottom head 2, connecting conducting wire and binding post 12 are drawn by the upper cover interstitial hole, can be directly and power connection, seal washer 9, plain washer 10 and clamp nut 11 are housed on the upper cover 1, integral installation is tightened sealing on liquid container, fin respectively has row's screw-driving up and down.
This heater mono-tube design is made power adjustments changeable PTC electric heating element sheet number and is realized.Requirement power is big, and the sheet number increases, otherwise opposite.During multitube three-phase connection, the single tube number that reliably increases and decreases every phase is realized the increase and decrease of power.
The utility model is owing to adopted binding agent, conducting strip is effectively connected with the PTC electric heating element, improved the electric heating exchange rate, save electric energy, the response time is fast, and heat conduction is rapid, long service life, can be installed on the various liquid containers, be used to add various static or flowing liquids such as hot water, oil, acid-base solution, be well suited for on-the-spot the use.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is illustrated.
Coat bonding agent 6 equably between PTC electric heating element 5 and the aluminium conducting strip 7, fill with insulating material 8 between conducting strip 7 and the stainless steel tube 3, insulating material 8 is the imines film, guarantee the insulation of conducting strip 7 and tube wall, then, integral body is compacted into the flat tube shape, and aluminum alloy heat sink 4 is installed in stainless steel flat tube outer wall both sides, increases area of dissipation.Its upper/lower terminal is equipped with upper cover 1 and bottom head 2, connecting conducting wire and binding post 12 are drawn by the upper cover interstitial hole, can be directly and power connection, seal washer 9, plain washer 10 and clamp nut 11 are housed on the upper cover 1, integral installation is on liquid container, tighten sealing, fin respectively has row's screw-driving up and down.This heating installation power supply power supply single tube is single-phase to be connect on 220 volts of single phase poaer supplies, and for safety, its shell is answered ground connection.
