Abstract
The utility model discloses a kind of low temperature environment heat preservation cabinet, including a babinet, the box house is equipped with a thin film heater and controller, wherein the thin film heater includes heating film and radiator, film is heated to paste on a heat sink, controller includes temperature sensor and control module, and thin film heater is electrically connected with the controller.
Description
【Technical field】
The utility model belongs to electric mechanical engineering field, particularly relates to low temperature environment heat preservation cabinet.
【Background technology】
Air environment will bear -40 DEG C~70 DEG C of temperature environment when working, the variation of environment temperature makes in equipment
The junction temperature of device changes in module, and the variation repeatedly of device junction temperature is easy to cause heat fatigue, the thermal damage of device, so as to subtract
The service life of few device.Equipment is not easy to start in a low temperature of -40 DEG C, is likely to result in huge loss.
【Utility model content】
The purpose of this utility model is to provide a kind of low temperature environments to keep the temperature cabinet, to solve equipment in cold-starting
There are problems that, which causes the heat waste of device to injure, is not easy to start.
To achieve the above object, implementing the low temperature environment Warming machine case of the utility model includes a babinet, the box house
Equipped with a thin film heater and controller, the wherein thin film heater includes heating film and radiator, and heating film is pasted onto
On radiator, controller includes temperature sensor and control module, and thin film heater is electrically connected with the controller.
It is preferred that the heating film heats film for polyimides.
It is preferred that the babinet includes upper cover plate, the left plate being connected by screw with upper cover plate, front panel, back plate, right side
Plate, bottom plate are connected by screw with back plate, left plate, right plate, front panel, and thin film heater, controller are fixed by screw
In back plate.
Compared with prior art, cabinet inside temperature can be reduced by implementing the low temperature environment heat preservation cabinet of the utility model
Excursion, so as to reduce the excursion of device junction temperature, reduce the thermal damage to device because of temperature change, increase device
Service life, while also equipment is made to easier start up at low temperature.
【Description of the drawings】
Fig. 1 keeps the temperature casing structure schematic diagram for low temperature environment.
Fig. 2 is that low temperature environment keeps the temperature the structure diagram after cabinet removing upper cover plate.
Fig. 3 is the thin film heater structure diagram that low temperature environment keeps the temperature cabinet.
Fig. 4 is that low temperature environment keeps the temperature the thin film heater of cabinet and the scheme of installation of controller.
【Specific embodiment】
Please refer to Fig.1 with shown in Fig. 2, the low temperature environment Warming machine case include a babinet, the box cover plate 1, with upper cover
Left plate 2 that plate 1 is connected by screw, front panel 3, back plate 5, right plate 6, bottom plate 4 by screw and back plate 5, left plate 2,
Right plate 6, front panel 3 connect.Thin film heater 10, controller 13 are fixed by screws in back plate 5.
Thin film heater 10 is made of heating film 12 and radiator 11, and heating film 12 heats film for polyimides,
Heating film 12 is pasted onto on radiator 11.Controller 13 is made of temperature sensor and control module.Thin film heater 10 with
Controller 13 is electrically connected.
It refers to shown in Fig. 3 and Fig. 4, the temperature sensor detection cabinet internal temperature on controller 13 works as cabinet inside
Temperature less than setting value when, controller starts heating film 12 and heats, and heating film 12 generates heat and to radiator 11
Heating, the heat of radiator 11 are scattered to cabinet inside, raise the temperature of cabinet inside, the device junction temperature rise in module, when
When temperature sensor detects the temperature of cabinet inside higher than the value set, heating film 12 stops heating.
Compared with prior art, cabinet inside temperature can be reduced by implementing the low temperature environment heat preservation cabinet of the utility model
Excursion, so as to reduce the excursion of device junction temperature, reduce the thermal damage to device because of temperature change, increase device
Service life, while also equipment is made to easier start up at low temperature.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model
Scope of the claims.
