Description
Technical field
The utility model relates to resistance heater, particularly a kind of intensive positive temperature coefficient thermistor heater.
Background technology
At warm-air drier, dryer, in the industry such as water heater and air conditioner, require the product can Quick heating load, therefore, on a lot of products, be provided with PCT heater, PCT heater meets users' demand with the advantage of himself, especially in air conditioner industry, traditional intensive positive temperature coefficient thermistor heater is received favor more, as Chinese patent notification number CN 2917152Y has announced a kind of intensive positive temperature coefficient thermistor heater, it comprises heater element, electrode terminal, hold cavity and finned fin, heater element is placed on and holds in cavity, hold cavity and finned fin is one-body molded, the two ends accent that holds cavity is sealed with seal, and described electrode terminal stretches out from hold the seal of cavity one or both ends accent.This patent makes PTC heater element be positioned at hermetic structure, has solved waterproof and the Insulation Problems of conventional P TC heater product, makes that product is safer, heat dispersion is better.But, traditional its radiating fin dense arrangement of intensive positive temperature coefficient thermistor heater at present, in the time of radiating fin and cross-ventilation heat exchange, because the gap between adjacent radiating fin is less, air is easily obstructed, and causes radiating efficiency lower.Meanwhile, radiating fin is formed by the good noble metal manufacture of radiating effect often, and radiating fin material consumptive material is higher, makes product cost higher.
Utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, provides the higher and cost of a kind of heat exchange efficiency compared with the intensive positive temperature coefficient thermistor heater at the end.
The technical scheme that realizes the utility model object is: a kind of intensive positive temperature coefficient thermistor heater, comprise heating tube, heating tube has tube chamber, in tube chamber, be provided with heating element, on heating tube, be provided with multi-disc radiating fin, multi-disc radiating fin is intensive shape spread configuration in the both sides of heating tube, on every a slice radiating fin, all offer the louvre of circulation heat transmission, by louvre is set on radiating fin, air can be circulated on radiating fin fast, accelerate heat transfer rate, improve heat exchange efficiency; Meanwhile, on radiating fin, offer louvre, can reduce precious metal material consumption, reduce product cost.
Louvre described in the utility model is at least one, and the interruption-like rule of multiple louvres arranges, and accelerates the heat transfer rate of radiating fin, improves radiating efficiency.
Further, the set-up mode of the louvre of the described every a slice radiating fin that is arranged in heating tube homonymy is all identical, the louvre being arranged on the multi-disc radiating fin same position of heating tube homonymy is located on the same line, form a beeline channel for circulation of air, therefore, multiple louvres 21 on diverse location form many air ducts, are conducive to air circulate, improve heat exchange efficiency.
Heating tube described in the utility model is the body that cross section is square, and in the tube chamber of body, is provided with heating element, and heating provides heat.
For anti-sealing penetrates in heating tube, and then cause the circuit in heating tube to be short-circuited, described heating tube and radiating fin are one-body molded, and heating tube is sealed at both ends good; Meanwhile, integral structure saves follow-up manufacturing procedure, cuts down finished cost; In addition, integral structure can ensure that heating tube fully contacts with radiating fin, is conducive to the conduction of heat and distributes, and improves heat exchange efficiency.
Preferably, described heating tube two ends are provided with left and right mount pad, left and right is provided with cavity on mount pad one end, left and right mount pad is respectively by the sheathed two ends that are arranged on heating tube of cavity, on the cavity wall of described left and right mount pad, be respectively arranged with elastic clamping hook, on the tube wall of heating tube two ends, be also respectively arranged with the draw-in groove that coordinates snap fit to snap in, in the time that left and right mount pad is inserted on heating tube, snap fit on heating tube wall snaps in the draw-in groove of left and right mount pad automatically, realize fixing stuck, complete installation, make left and right mount pad installation process time saving and energy saving, efficiency is high, more be conducive to batch production.
The beneficial effects of the utility model are: adopt by louvre is set on radiating fin, air can be circulated on radiating fin fast, accelerate heat transfer rate, improve heat exchange efficiency; Meanwhile, on radiating fin, offer louvre, can reduce precious metal material consumption, reduce product cost.
