Abstract
The utility model relates to a temperature control circuit of fuel cells, comprising a temperature measurement unit, a control unit and a heat dissipation unit; wherein, the output end of the temperature measurement unit is connected with the control unit outputting control signals to the heat dissipation unit. When the fuel cell works, the circuit can detect the temperature of the cell in real time, as well as automatically turn on or off the heat dissipation device according to the temperature to cool the fuel cell; meanwhile, when the temperature is over the set temperature, i.e. the temperature is ultra-high, the circuit alarms to hint that the fuel cell operates abnormally so as to effectively achieve automatic cooling and timely warning when the temperature is ultra-high as well as to guarantee the normal operation of the fuel cell.
Description
Technical field
The utility model relates to a kind of fuel cell temperature control circuit.
Background technology
Fuel cell is in the process of operation, can distribute a large amount of heats, yet along with the increase of battery capacity and the increase of output power, can not satisfy the temperature requirement of battery operate as normal by the heat radiation of common radiator realization fuel cell, and the common circuit more complicated of existing real-time heat sink, the cost of application is higher relatively.

The utility model has overcome above-mentioned shortcoming, provides a kind of and simple in structure, easy and simple to handle can detect fuel battery temperature in real time, and realized the fuel cell temperature control circuit of heat radiation.
The technical scheme in the invention for solving the technical problem is: a kind of fuel cell temperature control circuit, comprise temperature measuring unit, control module and heat-sink unit, the output terminal of described temperature measuring unit links to each other with described control module, and described control module is exported to described heat-sink unit with control signal.
Also can comprise alarm unit, described alarm unit links to each other with the output terminal of described control module.
Described heat-sink unit can comprise fan and driving triode, and an end of described fan links to each other with working power, and the other end is connected to the collector of described driving triode, the grounded emitter of described triode, and base stage links to each other with described control module.
Described alarm unit can comprise that hummer and another drive triode, and an end of described hummer links to each other with working power, and the other end is connected to the collector of described driving triode, the grounded emitter of described triode, and base stage links to each other with described control module.
Described control module can comprise single-chip microcomputer and peripheral circuit thereof.
Described temperature measuring unit can comprise temperature sensor.
The utility model can be when fuel cell operation, detect the temperature of fuel cell in real time, and open or close heat abstractor automatically according to temperature and come fuel cell is lowered the temperature, surpass design temperature in temperature simultaneously, when being the temperature superelevation, it is undesired to send the alarm fuel cell operation, effectively reaches automatic heat radiation and warning in time after the temperature superelevation, has guaranteed that fuel cell normally moves.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the process flow diagram of control module control procedure in the utility model.
Embodiment
As shown in fig. 1, the utility model is made of temperature measuring unit, control module, heat-sink unit and alarm unit, the output terminal of described temperature measuring unit links to each other with described control module, detected temperature signal is sent to described control module, described control module according to detected temperature value, is exported to control signal corresponding described heat-sink unit and alarm unit with control signal respectively.
Described control module comprises single-chip microcomputer U1 and peripheral circuit thereof, described temperature measuring unit comprises temperature sensor P1, described temperature sensor P is arranged in the fuel cell, detects the temperature that heat radiation produces in the fuel cell operation process, and detected temperature signal is sent among the described single-chip microcomputer U1.Described heat-sink unit comprises fan B1 and drives triode Q2, the end of described fan B1 links to each other with working power VCC, the other end is connected to the collector of described driving triode Q2, the grounded emitter of described triode Q2, and base stage links to each other with the output terminal of described single-chip microcomputer U1 through resistance R 3.Described alarm unit comprises that hummer LS1 and another drive triode Q1, the end of described hummer LS1 links to each other with working power VCC, the other end is connected to the collector of described driving triode Q1 by resistance R 2, the emitter Q1 ground connection of described triode, base stage link to each other with the output terminal of described single-chip microcomputer U1 after resistance R 1 again.
Based on said structure, the course of work of the present utility model as shown in Figure 2, after fuel cell start operation, single-chip microcomputer records the temperature of fuel cell in real time by temperature measuring unit.When temperature was lower than design temperature 1 (promptly being in low temperature), single-chip microcomputer cut out fan by heat-sink unit; When temperature was higher than design temperature 2 (promptly being in high temperature), single-chip microcomputer was opened fan by heat-sink unit; When temperature was higher than design temperature 3 (promptly being in superhigh temperature), single-chip microcomputer sent warning by warning circuit, and the prompting battery temperature is too high, and in time shut down maintenance.Described fan can directly dispel the heat of described fuel cell surface, also can dispel the heat on the heating radiator towards heating radiator F, reaches better radiating effect.
More than fuel cell temperature control circuit provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
