The principle of this linear pattern heat dissipating method is to drive air port into from the side of tester two to enter cold wind, and install fan at tester back absorbs heat wind outward.This method for designing is to actuate cold wind by the suction of fan below to enter from two sides, reaches the circulation theory of cold and hot exchange；According to aerohydrodynamics principle, cold air in lower section, hot-air up, its air inlet and air outlet almost height in the same horizontal line, this heat dissipating method exists clearly disadvantageous, so results in following a few point defects：
First, the cold wind for entering from top air inlet do not carry out with hot blast also it is cold and hot exchange, just siphoned away by fan below, cold wind is not effectively used, it is impossible to effectively utilize cold wind to radiate；
Secondly, under being acted under the suction of fan, instrument internal pressure can enter in instrument once again under pressure difference effect from the hot blast being blown out below less than outside from instrument afterbody cold wind air intake vent on the upper side, greatly reduce its effective radiating effect；
Again, cold wind is too small with the contact surface of instrument internal, does not do heat dissipation wind channel, air's circulation is exchanged and is rationally used, and the effect of its cooling greatly reduces, and is not reaching to expected effect.

Specific embodiment
With reference to embodiment, the invention will be described in further detail.
Embodiment 1：
Existing feeder automation tester is because with analog output function, operating power consumption is larger, internal electronic component caloric value is larger, it is too high so as to result in tester internal temperature, if prolonged work under such circumstances, internal component can be caused to damage, have a strong impact on its service life.And the linear pattern heat dissipating method that existing tester is used, cold and hot exchange process is insufficient, and radiating effect is difficult but getting a desired effect.
The invention of this example provides the cooling control system and control method of a kind of feeder automation tester; U-shaped air duct radiation method is designed to control the temperature inside tester; its running temperature is effectively reduced, so as to protect the electronic component inside tester, extends its service life.
The system is mainly made up of 1 cold air inlet, 2 cold wind induced draught fans, 3 air channel ventilating openings, 4 aluminium alloy radiating blocks, 5 high-power heater members, 6 hot blast induced draught fans, 7 hot air outlets,As schemed 1It is shown.
The system uses U-shaped air channel, i.e., the pipeline or passage of U-shaped ventilation, is relatively closed a U-shaped cavity or passage,As schemed 2It is shown.In order to ensure the flow direction of the wind in U-shaped air channel circulates according to the circuit of design, it is necessary to open air port, the predetermined flow direction circulation of guiding wind direction in corresponding position.
Aluminium alloy radiating module of the U-shaped air channel of present invention design by means of W types.As schemed 3It is shown to complete.This special W type radiating modules upper surface smooths, and is easily installed high-power heater members 5；Bottom is the radiation tooth 10 of W types, and its spacing is big, is easy to the quick circulation of cold wind.Complete U-shaped heat dissipation wind channel,As schemed 2It is shown, by the radiation tooth and tester bottom plate of W type radiating modules bottom formed relatively closed cold wind air channel 8, the upper surface of aluminium alloy radiating block of W types and the upper cover plate of tester formed cold-hot air convection exchange dissipate convection of heat air channel 9 constitute, cold wind in the air channel of tester bottom enters into the convection current air channel 9 on top by the anterior air channel ventilating opening 3 of aluminium alloy radiating block, and the hot blast with top carries out thermal convection current.Material is thus formed a complete U-shaped heat dissipation wind channel.Figure 2It is the radiating signal of the forced convection in the thermal convection current controlled by U-shaped heat dissipation wind channelFigure, it is main radiating mode of the present invention.Since being forced convection, it is necessary to which motive force and absorption affinity by means of fan promote the convection current of air to carry out convection current according to the route of design.
Control method proposed by the present invention is according to aerohydrodynamics principle, the radiating mode of the thermal convection current in the three kinds of modes that radiated using heat transfer, using unique U-shaped air channel, using the radiating mode of the forced convection in thermal convection current.
