Embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As Fig. 1, the automatic clinical chemistry analyzer that is used for shown in Figure 3 with reagent dish cold storage plant, comprise reagent storehouse 8, heat-insulation layer 9, temperature sensor 1, axle sleeve 11 and cooling assembly 2, described cooling assembly 2 comprises as shown in Figure 2: adopt the electricity of direct current supply to cause cooling piece 3, cool accumulating block 5, heating radiator 6, aerofoil fan 7 and connector 4; This assembly 2 is fixed to described reagent storehouse 8 by the screw hole of being opened on the cool accumulating block 5; The hot junction of described cooling piece 3 is coated with behind the heat-conducting glue the directly top base 21 of contact heating radiator 6, and the cold junction of described cooling piece 3 is coated with behind the heat-conducting glue the directly bottom of contact cool accumulating block 5; Described connector 4 is used for fixing electricity and causes cooling piece 3 and cool accumulating block 5, it by screw retention at the top of heating radiator 6 base 21, and cool accumulating block 5 by screw retention on it; Described electricity causes the lead of cooling piece 3 and draws by the groove of connector bottom; Described aerofoil fan 7 is fixed on the side of heating radiator 6.
The screw hole of being opened on the described cool accumulating block 5 by position intermediate, has 4 at an upper portion thereof; The attachment screw of described connector 4 and heating radiator 6 top bases 21 is positioned at the two ends of connector 4, has two; Described cool accumulating block 5 is positioned on four angles of cool accumulating block 5 and connector 4 with the attachment screw of connector 4, has 4.
4 screw holes by in the middle of the cool accumulating block 5 are connected with reagent storehouse 8 cooling assembly 2 by screw 12.The advantage of this structure is, during as any one part in the need replacing cooling assembly 2, only the screw that need unscrew in the reagent storehouse 8 just can load and unload very easily, and heat-insulation layer 9 has been reserved position, hole 13 here, only need tighten these 8 screws when installing once more and get final product, can not destroy heat-insulation layer.
Heating radiator top base 21 is contact cooling piece hot junction directly, and base 22 directly contacts work top, aerofoil fan 7 air blast backward in the past, forced air-cooling.As shown in Figure 4, heating radiator 6 adopts extraordinary section bar to be equipped with high rib fin 18 extruding of high density to form.Top base 21 and base 22 have the winglet chip architecture 20 of highly about 5mm in extruding place, are used for high rib fin 18 is squeezed into two base portions of heating radiator, finally make base portion follow high rib fin 18 integrators.
As shown in Figure 5, high rib fin 18 is divided into separate 3 sections along heating radiator 6 length directions.The purpose of fin segmentation is to suppress the growth of thermal boundary layer 19.If not segmentation, then the thickness of thermal boundary layer develops into Δ 2 in the exit of heating radiator, and each section boundary layer thickness only is a Δ 1 after the segmentation.Obvious Δ 1＜Δ 2.Because boundary layer thickness is more little, help more conducting heat, so strengthened the cross-ventilation heat exchange after the fin segmentation, improve the heat exchange efficiency of heating radiator, thereby improved the overall efficiency of refrigerating plant.If the note refrigerating capacity is Q, the electric power of consumption is P, and the note refrigerating efficiency is η=Q/P, and so, the refrigerating efficiency of general semiconductor cooling device is about 10～15%, and the efficient of this device can reach 25/ (12 * 10)=20%.
As shown in Figure 3, circumferential collecting ring 16, radially collecting ring 17 and osculum 15 are left in 8 bottoms, reagent storehouse.In case condensate water gathers too much, can derive by osculum 15 automatically.
Described reagent storehouse 8 adopts the thin-walled aluminium sheet to make; 9 of heat-insulation layers are that directly 8 outside foaming form the employing expanded material in the reagent storehouse.As shown in Figure 6, the bottom of heat-insulation layer 9 has square hole, reagent disk drive shaft hole 14 and the osculum 15 that is used to install cooling assembly 2.
Enforcement of the present utility model, be not limited to the disclosed mode of above most preferred embodiment, based on mentality of designing of the present utility model, simply deduce and replace, such as: remove fan, the type of cooling of heating radiator is changed into water-cooled,, also all belong to enforcement of the present utility model though can reach further raising refrigerating efficiency.
