Abstract
The utility model relates to a refrigeration & heating device which is made by semiconductor elements. A cold room is a container with an opening upwards. A cover without holes or with holes is arranged on the cold room. A heat radiation system is positioned beside the cold room or on the lower side of the cold room. A semiconductor refrigeration block is installed between the cold room and the heat radiation system. The heat radiation system can be cooled by the water or the wind. A reversing switch and a temperature control device are installed between a voltage reduction rectification power supply and the semiconductor refrigeration block. The reversing switch and the temperature control device are used for selecting the refrigeration or heating function and regulating temperatures. The utility model can refrigerate as well as heat. The utility model has the advantages of high refrigeration efficiency, convenient operation, and no noise. The utility model can be used for each field of the chemistry, biology, medicine, etc.
Description
The utility model relates to a kind of refrigeration and heater.
Employed constant temperature water bath apparatus in laboratory or baking oven can only be used for heating at present, no refrigerating function, and much the experiment that need finish at low temperatures can only be carried out at the refrigerator refrigerator or in ice bath (ice cube floats in the water), and operation both bothered, and the result is inaccurate again.
The purpose of this utility model be to provide a kind of can freeze and can heat, easy to operate, and also can be with the cooling and heating device of function of temperature control.
The utility model is made up of cold house, semiconductor refrigerating piece, fluid cooling system and step-down rectifier device etc.The cold house is the container that opening makes progress, and cooling system is positioned at the next door, cold house or is positioned under the cold house; The semiconductor refrigerating piece is installed between fluid cooling system and the cold house, and the semiconductor refrigerating piece is fixed with heat-conducting plate or the one group of conducting strip that is in the cold house towards the one side of cold house, is fixed with the fin that stretches to the fluid cooling system towards the one side of fluid cooling system; The fluid cooling system is designed to the container of a water inlet and a delivery port, also can be designed to the small fan that wind direction is aimed at fin; The direct current output of step-down rectifier device is access to the two poles of the earth of semiconductor refrigerating piece through reversing switch.
In order to be incubated and using electricity wisely, also can around the cold house, to add and do heat-insulation layer, opening configuration atresia or lid with holes in the cold house with heat-barrier material.
The utility model also can add temperature regulating device.Temperature regulating device is connected between step-down rectifier device and semiconductor refrigerating piece the two poles of the earth, and its temp probe stretches in the cold house.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is a kind of electrical schematic diagram of the present utility model.
Among the figure, (1) is the cold house, in actual applications, can contain a certain amount of water as water-bath in the cold house, if serviceability temperature is lower than 0 ℃, needs to add salt or glycerine or other water-soluble non-toxic non-corrosiveness materials to reduce the freezing point of water in water; (2) be conducting strip, be used to conduct heat; (3) be the semiconductor refrigerating piece, forward when energising refrigeration heats during reverse energising; (4) be fin; (5) and (6) be respectively delivery port and water inlet; (7) be the step-down rectifier device, provide dc source to the semiconductor refrigerating piece; (8) be reversing switch, be used to change the sense of current, to select refrigeration or heating; (9) be attemperating unit, be used to adjust steady temperature; (10) be temp probe, be used to respond to cold house's temperature; (11) be heat-insulation layer; (12) be lid.
During use, connect water inlet pipe and outlet pipe earlier, plug in again, as required switch is pulled out to freezing or heating shelves and transfer to the knob on the attemperating unit temperature required.
The utility model has the advantage of and can freeze and can heat, easy and simple to handle, and simple in structure, volume is little, noiselessness, the refrigerating efficiency height can be widely used in each field such as chemistry, biology, medical science.
