With reference to the accompanying drawing, it elaborates to some embodiments of the utility model, in the absence of conflict, under
The feature in embodiment and embodiment stated can be combined with each other.
As depicted in figs. 1 and 2, the refrigeration temperature control mould group 100 of the utility model embodiment includes: radiating module 20, thermoelectricity
Refrigerator 30, blower 40, sealing element 12, guide portion 11 and cold finger 50.Wherein, radiating module 20, thermoelectric cooler 30 and cold
Refer to 50 sequentially stacking assembly, blower 40 be embedded at a side of radiating module 20, sealing element 12 be matched with radiating module 20 so that
Constitute heat dissipation wind channel in radiating module 20, guide portion 11 be assemblied in sealing element 12 with by 40 non-corresponding of blower in radiating module 40
Wind is guided into heat dissipation wind channel.
In the present embodiment, the radiating module 20, thermoelectric cooler 30 and cold finger 50 are stacked in the vertical direction, blower
40 are set on the side of radiating module 20 by embedded, and the wind direction of the blower 40 is towards horizontal direction, such that blower
40 side blows can be greatly saved the bulk of vertical direction while meeting functional requirement, and satisfaction can be applied
Demand in the electronic product of small size.
As shown in Figures 2 and 3, which includes pedestal 21 and several fins 22 being set on pedestal 21,
Several fins 22 can be set in parallel on pedestal 21.Wherein, part fin 22 corresponds to the air outlet of blower 40, the wind
Machine 40 selects aerofoil fan, so as to form the effect of side blow.Preferably so that blower as much as possible 40 corresponds to
Fin 22 corresponds to the air outlet of blower 40, to improve radiating efficiency.
In the present embodiment, which is copper-based seat 21, and fin 22 is aluminum fin-stock, and aluminum fin-stock is fixed by welding
On copper-based seat 21, heat dissipation area increases by 70% or so compared to the radiator of common process for machining manufacture, makes the effect of blower 40
Rate maximizes, and quickly the heat transfer that the hot end of thermoelectric cooler 30 generates is gone out, prevents 30 hot-face temperature of thermoelectric cooler
Rise.The cold finger 50 is made of aluminum material, so as to have preferable heat conductive.
As shown in Figure 1 to Figure 3, which includes the recessed portion 23 for being set to 21 side of pedestal, and blower 40 assembles
In in recessed portion 23, such that 40 partial embedding of blower is in radiating module 20, so as to reduce refrigeration temperature control mould group 100
In the size of vertical direction, the overall dimensions of refrigeration temperature control mould group 100 are further reduced.Wherein, the blower 40 and fin 22
Between be equipped with spacing, the spacing be not less than 2mm.In the present embodiment, the end face of part fin 22 is correspondingly arranged on joint face, connection
Face is equipped with threaded hole, which is fixed on the joint face by screw.
The sealing element 12 of the utility model is air duct cover board, and the air duct cover board and the cooperation of pedestal 21 constitute the wind of blower 40
Road.In the present embodiment, it is correspondingly provided with connecting hole on air duct cover board, pedestal 21 and cold finger 50, which is located at side.The air duct
Cover board, radiating module 20, thermoelectric cooler 30 and cold finger 50 wear threaded connection fixing assembling, thermoelectric cooler 30 by screw
Fixed clamp is between pedestal 21 and cold finger 50.Wherein, screw uses plastic screw, and the ingredient of plastic screw is nylon, so
So that screw heating conduction is poor, the hot end energy of thermoelectric cooler 30 can be effectively prevent to be transferred directly to cold finger 50, reduced
The cold end of thermoelectric cooler 30 leaks heat.
Further, guide portion 11 is the pod being assemblied on air duct cover board.The pod and recessed portion 23 cooperate structure
At the accommodating space of blower 40.In the present embodiment, by the design of pod, so that air-flow caused by blower 40 flows into water conservancy diversion
The heat dissipation wind channel of cover, air duct cover board and radiating module composition, can be lost, to further improve to avoid the air quantity of blower 40
Radiating efficiency.
Wherein, which has been respectively coated with respect to the side of the side of radiating module 20 and opposite cold finger 50 and has led
Hot silicone grease layer (not shown), to reduce the thermal contact resistance on 30 surface of thermoelectric cooler.The working principle of the thermoelectric cooler 30 are as follows:
P-N junction is formed using semiconductor material, the direct current by load at both ends freezes, when electric current is between p-type and n type material
When alternately flowing, heat is transferred to the other end from one end of thermoelectric cooler 30.The thermoelectric cooler 30 has cleaning, noiseless
The advantages that pollution, high reliablity, stability is good and high accuracy temperature control, is used widely in each field.
When the both ends to thermoelectric cooler 30 apply DC voltage, heat is transferred to from the lower surface of thermoelectric cooler 30
Upper surface (i.e. heat is transferred to and 20 opposite side face of radiating module from the one side opposite with cold finger 50 of thermoelectric cooler 30),
To realize the refrigeration effect to cold finger 50.After opening blower 40 simultaneously, cold air is sucked from natural environment, passes through water conservancy diversion
Cover, air duct cover board and radiating module form closed heat dissipation wind channel, and the heat transfer for gathering 30 hot end of thermoelectric cooler is arrived
In air, the thermal balance of whole system is realized, guarantee that cold finger 50 is continuously maintained within the scope of lower temperature.
In addition, refrigeration temperature control mould group 100 further includes the blower protective net 41 for being fixed on blower 40, blower protective net 41 is located at blower
40 air intake vent.Specifically, which is fixed on the lateral surface of blower 40 by screw.The utility model passes through the wind
The design of machine protective net 41 can play the role of protecting blower 40, avoid sucking sundries and lead to motor damage.In addition, passing through
The design of pore size on blower protective net 41 can also play the role of stopping larger particles dust.
The utility model breaks through the assembly method of conventional refrigerant temperature control mould group, and all parts of refrigeration temperature control mould group are designed
For in the assemble sequence of vertical direction, and blower is embedded in the side of radiating module, has been greatly saved the space of vertical direction
Size, the mode of side air inlet/outlet make refrigeration temperature control mould group have continual and steady refrigerating capacity, guarantee target object lower
In temperature range.
Those skilled in the art are considering specification and after practicing utility model disclosed herein, will readily occur to practical
Novel other embodiments.This application is intended to cover any variations, uses, or adaptations of the utility model, these
Variations, uses, or adaptations follow the general principle of the utility model and including undocumented skills of the utility model
Common knowledge or conventional techniques in art field.The description and examples are only to be considered as illustrative, the utility model
True scope and spirit are pointed out by claims hereof.
It should be understood that the utility model is not limited to the accurate knot for being described above and being shown in the accompanying drawings
