Abstract
The utility model provides a heating device of an electronic apparatus, belonging to the field of auxiliary heating technology for electronic apparatuses. The structure of the heating device comprises a rectangular fixing support, the upper surface of the fixing support is provided with an upper mica lamination provided with radiating fins, a lower mica lamination, and a resistance wire therebetween which is connected with a cable, the upper mica lamination, the radiating fins and the lower mica lamination are fixed on the fixing support by a fixing component. In order to prevent overheating of local temperature, the cable is provided with a temperature controller for effectively controlling temperature. Compared with the prior art, the utility model has the characteristics of reasonable design, simple structure, low-cost manufacture and convenient installation, since the mica laminations have good insulating and heat-conducting property, the electric energy and the heat energy can be separated effectively, which is safe and reliable, the fault incidence of a repeater exchanger with the heating device can be reduced.
Description
(1) technical field
The utility model relates to a kind of assistant heating technology of electronic equipment, specifically a kind of electronic equipment heater.
(2) background technology
Though the Ethernet advanced technology exists trunking switch major part can only be installed in outside the building characteristics easily affected by environment.As arrived annual winter, the phenomenon that always exists exchange fault to increase.The increase of failure rate has not only increased the work of maintenance personnel amount, has increased maintenance cost, and has influenced service quality.For this reason, must improve stability of network, find by inquiry, switch relatively more outstanding time period of breaking down is that the failure rate of switch obviously increased after winter temperature lower time, especially temperature dropped to below 0 ℃.
Though it is many-sided causing the reason of fault, such as power failure, cable, user, machine room, equipment or the like, but tangible increase and decrease can not take place with changes of seasons in reasons such as power failure, cable, user, machine room, have only equipment itself just may change, because the normal operation circumstances of electronic product is closely-related with variations in temperature because of the variation of seasonal temperature.The reason that causes winter equipment failure rate to increase has following several aspect: winter temperature obviously descends, cabinet is placed on the positive ventilation of the back of the body, bad, the measure of not heating of cabinet itself sealing itself, cabinet does not have heat-insulation layer etc., these all can cause the facility environment temperature low, increase breakdown rate, the working temperature that the reason that equipment failure rate is high also is electronic product itself is limited.Above-mentioned various reasons, some are arranged is insurmountable, can only be placed on the position that can lay in the practice of construction environment, has no idea to change; Increase the thickness of cabinet and increase the raising that heat-insulation layer can not fundamentally change the temperature in the cabinet, and increase heat-insulation layer or cabinet thickness is unfavorable for the heat radiation in summer again.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, provides a kind of way by heating to improve temperature in the cabinet, reaches the suitable working temperature of electronic product, reduces the electronic equipment heater of its failure rate.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of electronic equipment heater, comprise fixed support, support bracket fastened upper surface is provided with mica sheet and following mica sheet, accompany the resistance wire that joins with cable between last mica sheet and the following mica sheet, last mica sheet is provided with fin, and fin, last mica sheet and following mica sheet are fixed on the fixed support by fixed part.
Above-mentioned electronic equipment heater, too high in order to prevent the temperature part, on cable, also be provided with thermostat.When temperature reach a certain height, thermostat cut off the power supply to resistance wire, stopped heating; Energising heating again after temperature lowers, the temperature in the cabinet will keep the temperature of a suitable electronic product operate as normal always like this.
Electronic equipment heater of the present utility model compared with prior art, the beneficial effect that is produced is:
1) reasonable in design, simple in structure, low cost of manufacture, easy to install;
2) because mica sheet has insulation and characteristics such as good heat conductivity, thus electric energy and heat energy are effectively separated, safe and reliable, can effectively reduce the rate of breakdown of trunking switch after the use.
(4) description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, fixed support, 2, go up mica sheet, 3, mica sheet down, 4, resistance wire, 5, cable, 6, fin, 7, fixed part, 8, thermostat.
(5) embodiment
Below in conjunction with explaining below 1 pair of a kind of electronic equipment heater work of the present utility model of accompanying drawing.
As shown in Figure 1, a kind of electronic equipment heater of the present utility model, its structure comprises a rectangular fixed support 1, the upper surface of fixed support 1 is provided with mica sheet 2 and following mica sheet 3, accompany the resistance wire 4 that joins with cable 5 between last mica sheet 2 and the following mica sheet 3, last mica sheet 2 is provided with fin 6, and fin 6, last mica sheet 2 and following mica sheet 3 are fixed on the fixed support 1 by fixed part 7, also are provided with thermostat 8 on the cable 5.
A kind of its processing and fabricating of electronic equipment heater of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (2)
1, a kind of electronic equipment heater, comprise fixed support (1), it is characterized in that, the upper surface of fixed support (1) is provided with mica sheet (2) and following mica sheet (3), accompany the resistance wire (4) that joins with cable (5) between last mica sheet (2) and the following mica sheet (3), last mica sheet (2) is provided with fin (6), and fin (6), last mica sheet (2) and following mica sheet (3) are fixed on the fixed support (1) by fixed part (7).
