Description
Technical field
The utility model relates to a kind of hydraulic cooler, in particular, relates to that a kind of to have the cold-peace semiconductor refrigeration that catchments be the hydraulic oil cooling device of one.
Background technique
Hydraulic equipment is the core of hydraulic station, hydraulic oil is the dynamic medium of hydraulic equipment, hydraulic oil must keep certain stickiness could guarantee the using effect of hydraulic equipment, but hydraulic oil produces heat because conference is crossed in load at work, its stickiness is diminished, thereby can influence the stability that hydraulic system is used, just needing cooler is its cooling.Prior art is generally by water-cooled and air-cooled, the hydraulic system high to heat production, and cooling effect is not fine.
The model utility content
The utility model is at the deficiency of existing product, and a kind of hydraulic oil cooling device of simple in structure, practical, good cooling results is provided.
Hydraulic oil cooling device of the present utility model, comprise casing, be provided with semiconductor refrigerating sheet in the described casing casing is divided into upper half part and lower half portion, in casing upper half part hydraulic oil cooler is installed, fixed installation storage battery, temperature regulation switch, DC/DC circuit in casing lower half portion, described casing upper surface one end is equipped with the AC/DC power switch; Described AC/DC power switch is connected with the DC/DC circuit with power supply respectively by lead, connects respectively by lead between described storage battery, temperature regulation switch and the DC/DC circuit three, and described semiconductor refrigerating sheet is connected with temperature regulation switch.Described cabinet shell is made by aluminium sheet, is provided with thermal insulation layer in the middle of the shell.Described casing side is provided with water inlet and osculum, is provided with oil inlet hole and oil outlet above.
The beneficial effects of the utility model are: (1) is simple in structure, is easy to make; (2) practical, the cold-peace of catchmenting semiconductor refrigeration is one, good cooling results.(3) low cost of manufacture.
Description of drawings
Fig. 1 represents structural representation of the present utility model;
Fig. 2 represents the utility model control flow schematic representation;
Among the figure: casing 1, hydraulic oil cooler 2, AC/DC power switch 3, storage battery 4, semiconductor refrigerating sheet 5, temperature regulation switch 6, DC/DC circuit 7.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
In the drawings, hydraulic oil cooling device of the present utility model mainly is made up of casing 1, hydraulic oil cooler 2, AC/DC power switch 3, storage battery 4, semiconductor refrigerating sheet 5, temperature regulation switch 6, DC/DC circuit 7.
Be provided with semiconductor refrigerating sheet 5 in the described casing 1 casing 1 is divided into upper half part and lower half portion, in casing 1 upper half part hydraulic oil cooler 2 is installed, be installed with storage battery 4, temperature regulation switch 6, DC/DC circuit 7 in casing 1 lower half portion, described casing 1 upper surface one end is equipped with AC/DC power switch 3; Described AC/DC power switch 3 is connected with DC/DC circuit 7 with power supply respectively by lead, connects respectively by lead between described storage battery 4, temperature regulation switch 6 and DC/DC circuit 7 threes, and described semiconductor refrigerating sheet 5 is connected with temperature regulation switch 6.Described casing 1 shell is made by aluminium sheet, is provided with thermal insulation layer in the middle of the shell.Described casing 1 side is provided with water inlet and osculum, is provided with oil inlet hole and oil outlet above.
Hydraulic oil cooling device groundwork principle of the present utility model is semiconductor refrigerating sheet, also be thermoelectric module, be a kind of heat pump, its advantage is not have slide member, the occasion of be applied in that some spaces are restricted, reliability requirement height, no refrigeration agent polluting.Utilizing the Peltier effect of semi-conducting material, when galvanic couple that direct current is connected into by two kinds of different semi-conducting materials, can absorb heat at the two ends of galvanic couple respectively and emit heat, can realize the purpose of freezing, is a kind of refrigeration technology that produces negative thermal resistance.
When using hydraulic oil cooling device of the present utility model, at first connect power supply by AC/DC power switch 3, convert Ac to direct current, convert galvanic current to through DC/DC circuit 7 again, to semiconductor refrigerating sheet 5, another part is stored in the storage battery 4 a direct current part through temperature regulation switch 6 power supplies, when if unexpected power failure or certain parts go wrong, standby power supply can be provided, and temperature regulation switch 6 is regulated size of current as required, realizes semiconductor refrigeration.The shell centre that described casing 1 is made by aluminium sheet is provided with thermal insulation layer, can guarantee refrigeration heat insulation effect in the casing 1.Described casing 1 side is provided with water inlet and osculum, is provided with oil inlet hole and oil outlet above, and hydraulic oil exchanges a part of heat through water cooling, pass through the refrigeration of casing 1 semiconductor refrigeration again after, can guarantee the cooling effect of hydraulic oil better.
