Abstract
The utility model discloses an efficient PTC heat pipe heater. The PTC heat pipe heater comprises a shell, fins, heat pipes, a PTC ceramic heating element and an aluminum substrate. The fins, the heat pipes, the PTC ceramic heating element and the aluminum substrate are fixedly arranged inside the shell, and the PTC ceramic heating element and the aluminum substrate are fixedly arranged together; one ends of the heat pipes are arranged together with the aluminum substrate, and the set of fins are fixedly arranged at the other ends of the heat pipes. According to the utility model, the fins are arranged on the low temperature heat pipes, so that the heat exchange area of the heater is increased substantially, and the heat exchange efficiency is improved; the heat accumulated at the heat pipes is transmitted to a cooling area rapidly via the high conductivities of the heat pipes, so that a heat resistance is reduced; and water films are not easy to form on the surfaces of the fins made of hydrophobic aluminum foils, so that the heat convection of air to fins is improved, in conclusion, the performance of the PTC heater can be improved substantially, and the PTC heat pipe heater is simple in structure.
Description
Technical field
The utility model discloses a kind of heater, and a kind of heat pipe heater of PTC efficiently particularly is applied to the heat management field of wind energy power distribution cabinet.
Background technology
Along with more and more widely the application in people life of electron electric power system, need to use power distribution cabinet as centrally connected power source in a lot of systems.Because the use occasion of power distribution cabinet is indefinite; tend to be applied in some comparatively in the rugged environment; because the low temperature of external environment changes the formation that may cause wind energy power distribution cabinet dewfall; this may cause serious fault or the short circuit of rack utensil; and cause can't normal operation etc. hidden danger, therefore, can come it is protected by the application of heat device usually in the present power distribution cabinet; make it avoid low temperature harm, prevent the formation of dewfall.In addition, also some power distribution cabinet uses fan heater that the cross-ventilation performance is provided, and can better guarantee rack constant temperature.At present, the ptc heater that uses on the market mainly is to adopt PTC potsherd bonding (or soldering) fin to form, the limitation of this ptc heater is the heat exchange area deficiency, the technology of bonding fin increases the thermal resistance of heater, the aluminium fin of soldering is surface adsorbed film of water when variations in temperature easily, thereby influences heat exchange efficiency etc.
Summary of the invention
At above-mentioned mention of the prior art for the bad shortcoming of the heater effect of power distribution cabinet, the utility model provides a kind of new PTC heat pipe heater structure, it adopts special structure, and the structure with PCT ceramic heating plate cooperation aluminium base and wing plate reaches good heat-radiation effect.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of PTC heat pipe heater, heater comprises shell, fin, heat pipe, PTC ceramic heating plate and aluminium base, fin, heat pipe, PTC ceramic heating plate and aluminium base fixedly install in the enclosure, PTC ceramic heating plate and aluminium base are fixedly installed togather, heat pipe one end and aluminium base are installed together, and are installed with one group of fin on the other end.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Described aluminium base is provided with two, is respectively upper strata aluminium base and lower floor's aluminium base, and the upper strata aluminium base is arranged on PTC ceramic heating plate top, and lower floor's aluminium base is arranged on PTC ceramic heating plate below.
Aluminium base top, described upper strata and lower floor aluminium base below have U-shaped groove, and heat pipe is arranged in the U-shaped groove.
Corresponding to the fin position fan is installed on the described shell.
Described heat pipe is L-shaped.
Described fin adopts hydrophobic aluminum foil material to make.
The beneficial effects of the utility model are: the mode that the utility model is installed fin by Cryo Heat Tube increases considerably the heat exchange area of heater, improves heat exchange efficiency; The heat that utilizes the high conductance of heat pipe will accumulate in the heat pipe position is delivered to cooled region fast, thereby reduces thermal resistance; The fin surface that hydrophobic aluminium foil is made is difficult for forming moisture film, has improved the heat convection of air and fin.Comprehensive above 3 points, the utility model can increase substantially the performance of ptc heater, and simple in structure.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
