Abstract

The utility model discloses a heat dissipation device of a PTC die set, which is used for a device with high power consumption. The utility model comprises at least one basic unit; each basic unit comprises a machine box; at least one blower is respectively arranged on the front and the rear end surfaces of the machine box and serves as an air intake; the right and the left sides of the machine box serve as air outlets on which at least one PCT element is respectively arranged; an isolation air guiding plate with unevenness surfaces is slantwise arranged inside the machine box. The heat dissipation device of a PTC die set of the utility model has the advantages that air can flow in through the front and the rear ends of the machine box at the same time, and the air can flow out through both sides of the machine box at the same time; the isolation air guiding plate divides the space inside the machine box into two air channels to increase ventilation area effectively, so that the temperature of the outflow air can be raised effectively, power density can be increased, and space utilization rate can be improved; the cold air which is blown into from the end surfaces of the machine box can be formed into turbulent flow of the air as reaching each position of convex surfaces; the air can flow out through the lateral surfaces on corresponding positions, and an air guiding function of a slope surface can be overcome, so that the air can flow out uniformly on the whole air outflow surface.

Description

The PTC module radiator

Technical field

The utility model relates to the PTC module radiator in a kind of high-power power consumption devices.

Technical background

In the widely used at home at present high-power power consumption devices, great majority adopt pure resistance as the power consumption element, and with the high-power blower heat radiation, pure resistance has the red heat phenomenon during owing to work simultaneously, and security performance is relatively poor; In addition, the noise during fan operation is bigger.After the power consumption element changes PTC into, solved safety problem to a certain extent, but brought the low and bulky shortcoming of power density simultaneously, and directly caused the increase of blower fan quantity, thereby noise problem is more apparent outstanding.Chinese patent CN2525652Y discloses a kind of multilayer PCT module, overlapping in the place ahead of blower fan two to three PCT assemblies are set, be separated into a plurality of air channels by isolating aerofoil, be provided with one or more minor diameter blower fans in each air channel, the situation that can avoid like this can not normally starting owing to indivedual blower fans that interior " tacking " causes occurs, can improve leaving air temp, increase power density, reduce noise.The PTC module of this structure, solved the problem of power density and noise to a certain extent, but owing to only single PCT element is resolved into simply the assembly of two to three eclipsed forms, thereby its effect is very limited, can not fundamentally address this problem.

Summary of the invention

To be solved in the utility model is the problems referred to above that prior art exists, and aims to provide a kind ofly more effectively to reduce small product size, increase power density and with the less multilayer PTC module radiator of noise under the power condition.

For addressing the above problem, the technical solution adopted in the utility model is: the PTC module radiator, comprise at least one elementary cell, it is characterized in that described each elementary cell comprises cabinet, be respectively arranged with at least one blower fan as air inlet on the described cabinet front/rear end, the described cabinet left and right sides is respectively arranged with at least one PCT element as air outlet on it, the interior oblique isolation wind deflector with convex-concave surface that is provided with of described cabinet.

PTC module radiator of the present utility model, rear and front end while air intake from cabinet, both sides air-out simultaneously from cabinet, by isolating wind deflector the separated by spaces in the cabinet is become two air channels, effectively improve draught area, can effectively improve leaving air temp like this, increase power density, improve space availability ratio.Cold wind from the cabinet end face blows into arrives the turbulent flow that each the convex surface place that isolates wind deflector can form wind, from the side air-out of relevant position, overcomes the effect of slope wind-guiding, makes whole outlet air surface air-out even.

As further improvement of the utility model, described isolation wind deflector is a fin structure, and perhaps the surface has a lug.Described isolation wind deflector can also adopt the structure with identical cross section, as waveform, be stairstepping or other similarly have the version of male and fomale(M﹠F).

Further improve as the utility model, be provided with one or more minor diameter blower fan at each air channel air inlet, the situation that can avoid like this can not normally starting owing to indivedual blower fans that interior " tacking " causes occurs, and adorn the modularized radiating device that the PTC assembly constitutes by 2 air channels and side, can realize the modularization assembling, to satisfy the combination needs of different discharge powers; The utility model blower fan diameter can adopt 120mm, and the blower fan quantity of each elementary cell is 2～4, is advisable for 4～6 pairs of PTC elements provide heat radiation, reduces half blower fan use amount than the design of former air channel, can significantly reduce noise.

Use the utility model can increase by 70%～90% air-out area, reduce volume 40～50%, power density increases by 70%～90%, and noise reduces 40%～60%, and cost reduces 20%～40%.

Further improve as of the present utility model, two or more elementary cells are superimposed constituent components up and down.
