A kind of Shui nationality case lid
Technical field
The utility model belongs to a kind of case lid of aquarium, relate to the improvement of this cover structure, more specifically, be that a kind of its is provided with improved radiator structure, be suitable for installing and using the aquarium case lid of large-power lamps such as powerful fluorescent lamp or metal halid lamp.
Background technology
Operated by rotary motion has lighting in the case lid of aquarium, when using large-power lamp such as powerful fluorescent lamp and metal halid lamp, because of calorific value causes in the lamp greatly, the temperature of lamp outer casing and case lid is higher.Product on the existing market is for the heat radiation of large-power lamp, and its effect is all not good.Temperature is higher, makes the shell heating easily, allows the user that hot sensation is arranged, cause the inconvenience in the use, simultaneously, should not adopt plastics to do the shell of large-power lamps such as metal halid lamp again, cause aging, the distortion or the fault of parts easily, also may cause fire therefrom when serious.
Summary of the invention
The purpose of this utility model is will overcome above-mentioned defective and propose a kind of Shui nationality case lid, this Shui nationality case lid has good radiator structure, the heat that large-power lamp can the be sent external world of in time leading, thereby keeping Shui nationality case lid to be unlikely to gather because of internal heat makes housing produce too high temperature, be adapted to people and in use operate, and help reducing dangerous generation.
Its purpose is realized by following scheme:
A kind of Shui nationality case lid, be included in the Shui nationality case lid light fixture is set, be characterized in, light fixture has one can install reflection shield, fluorescent tube, the tubular chamber of lamp socket, be sealing around the tube wall of tubular chamber, fluorescent tube is arranged at the central authorities of tubular chamber, the both sides of chamber are made as into, go out ventilating opening, one or both sides at fluorescent tube are provided with fan, the wind that fan is drawn from air inlet mainly is sent to tubular chamber upper surface, or fan mainly is sent to air outlet from tubular chamber upper surface direction absorption wind, make the distinguished and admirable heat radiation ventilating duct that mainly leads by forming between the two sides, front and back of reflection shield and reflection shield top and tubular chamber upper surface to other end air outlet, by the left and right sides face of reflection shield and in the below forms that part is distinguished and admirable to be used for another ventilating duct that leads that fluorescent tube dispels the heat in reflection shield.
Like this, because the heat that light fixture produces is mainly built up the upper surface in tubular chamber, under the certain prerequisite of total blast volume, it is more that the air quantity that said structure flows toward tubular chamber upper surface is compared alternate manner, thereby can reach better radiating effect.
In the such scheme, fan arrangement has the wind-guiding baffle plate, and the wind that fan is drawn from air inlet mainly is sent to tubular chamber upper surface, or fan mainly is sent to air outlet from tubular chamber upper surface direction absorption wind.Like this, can more easily adjust the air quantity ratio of wind direction and upper and lower, the setting for fan simultaneously provides more design flexible mode.
In the such scheme, tubular chamber upper surface and aquarium cover the certain clearance space of formation between face.Can completely cut off direct the biography above Shui nationality case lid of heat that light fixture produces.
In the such scheme, the fan of air inlet or air outlet can be set to many, to increase total blast volume.
Shui nationality case lid of the present utility model, because adopting tubular chamber separates light fixture and case lid body, help reducing heat and directly be passed to the case lid body, and it is the heat guiding is extraneous from the side of tubular chamber, the heat that the upper surface of tubular chamber is gathered is concentrated the characteristics of handling with emphasis pointedly, simultaneously, the air-supply of guiding fan is divided into the moving wind of two plumes, wherein one dispels the heat to fluorescent tube targetedly, another burst while forms the pilot flow of heat radiation above reflection shield, can reach better heat radiating effect effectively.

Embodiment
Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail:
Embodiment one: see figures.1.and.2, these Shui nationality case lid comprises reflection shield 5, fluorescent tube 3, lamp socket 4 and tubular chamber 2.Be sealing around the tube wall of tubular chamber, its upper surface and front and rear end are made of tubular chamber main seat frame 2.1, and the lower surface is made of transparency glass plate 2.2 and installing rack 2.3; The both sides of chamber are made as air inlet 8 and air outlet 9.Reflection shield 5, fluorescent tube 3, lamp socket 4 are installed on tubular chamber 2 central authorities, be provided with two cover fan 6 and fan bases 7 at tubular chamber 2 in a side of fluorescent tube 3, fan 6 tilts to install to make its air supply direction facing to tubular chamber upper surface 2.11, fan base 7 is near an end of reflection shield 5, at fan with the lower part, its below and two sides, front and back and tubular chamber main seat frame 2.1 form sealing, fan base 7 is near an end of air inlet 8, with top, its top and two sides, front and back and tubular chamber main seat frame 2.1 form sealing at fan.Offer air vent 5.11 on the left and right sides plate 5.1 of reflection shield 5, form wind guide channel 11 between the two sides, front and back of reflection shield 5 and reflection shield 5 tops and tubular chamber 2 upper surfaces 2.11, in addition, tubular chamber upper surface 2.11 and above the Shui nationality case lid body between form certain clearance space 10.
Embodiment two: fan 6 is vertically installed, promptly fan 6 around all seal with tubular chamber 2, an end of air intake makes wind enter fan 6 from outside to inside at air inlet 8 places, and blows to the centre; One end of air-out makes wind outwards enter fan 6 in lamp, and blows to air outlet 9.Install wind-guiding baffle plate 12 additional in the inboard of two fans, make wind mainly blow to tubular chamber upper surface 2.11, or 2.11 absorptions are more windy from tubular chamber upper surface.Other parts of not addressing can be with reference to embodiment one.
Embodiment three: fan 6 levels are installed, and promptly fan 6 stays wind passage mouth near the end top of fluorescent tubes, and the below and about with tubular chamber 2 sealings; Fan 6 stays wind passage mouth away from an end of fluorescent tube below, and the top and about with tubular chamber sealing.And install wind-guiding baffle plate 12 at fan 6 additional near the wind passage mouth of fluorescent tube one ends, make wind mainly blow to tubular chamber upper surface 2.11, or from tubular chamber upper surface 2.11 draw more windy.Other parts of not addressing can be with reference to embodiment one.
Also can see by embodiment one and embodiment three, the mode that fan adopts level or installs near level, have and under the situation that does not increase case lid thickness, to use the more characteristics of large scale fan,, further improve the effect of heat radiation so that can adopt the increasing fan power as required.
