The specific embodiment
As shown in Figure 1, in a preferred embodiment of the invention, this water circulation automatic heat radiation frock is mainly used in the heat radiation of LED light source in senile experiment, and further, LED light source comprises LED aluminium base 500, and this water circulation automatic heat radiation frock comprises cooling water tank 100, the first water pipe 200 that is connected to respectively cooling water tank 100 two ends and the second water pipe 300 and the Control Component (figure does not illustrate with label) that is used for controlling cooling water tank 100 and extraneous water circulation.Be provided with the heat dissipation element of heat dispersion that can heat radiation water tank 100 in cooling water tank 100, and understandable, in order to improve radiating efficiency, cooling water tank 100 itself can adopt the material with good heat dispersion, for example, aluminium.Control Component comprises control circuit board (with label, not illustrating in figure), be electrically connected on respectively the temperature-sensitive element (with label, not illustrating in figure) at control circuit board two ends and be used for controlling the water circulation Control Component 600 of current break-make and water flow.Temperature-sensitive element and LED aluminium base 500 are electrically connected; The water level that the water level that the first water pipe 200 connects connects higher than the second water pipe 300, water circulation Control Component 600 are located on the second water pipe 300.
In addition, the outer surface of cooling water tank 100 also is provided with the fixture 400 for fixed L ED aluminium base 500, in the present invention, this fixture 400 comprises at least two fixed heads 401, and this fixed head 401 can be rotatably set in the surface of cooling water tank 100 by fixed axis (with label, not illustrating in figure).Can certainly adopt other forms of fixture to be fixed LED aluminium base 500, when the 400 pairs of LED aluminium bases 500 of fixture that adopt the preferred embodiment of the present invention are fixed, due to rotation fixed head 401, the edge that makes fixed head 401 push down LED aluminium base 500 can be completed fixing, therefore can improve to a certain extent test efficiency.
when testing, the first water pipe 200 and the second water pipe 300 are communicated with extraneous water environment (as pond), so that while needing, this water circulation automatic heat radiation frock can form water circulation with extraneous water environment, then LED is switched on, the temperature of LED aluminium base 500 rises, heat has been delivered on cooling water tank 100 simultaneously, the temperature of cooling water tank 100 rises simultaneously, when temperature reaches certain value, temperature-sensitive element is transferred to control circuit board with temperature value, control circuit board is controlled water circulation Control Component 600 and is opened (under normality, water circulation Control Component 600 is closed), make the water in extraneous water environment flow in cooling water tank 100.Because cooling water tank 100 temperature rise, the temperature of the water of the inside also can rise, hot water density reduces, hot water rises, so just can form the water circulation a little less than in the of, exchange with the water in extraneous water environment, if in this case, the temperature of LED aluminium base 500 and cooling water tank 100 continues to rise, temperature-sensitive element can send a signal to control circuit board so, control circuit board is controlled water circulation Control Component 600 and is accelerated the velocity of liquid assets of water, carries out quick heat radiating, so just can reach the purpose of temperature stabilization.Dispel the heat for more powerful LED, the volume of cooling water tank 100 can suitably do bigger, and area of dissipation can be larger like this, and the water yield that flows through also can be larger.
In a preferred embodiment of the invention, what the heat dissipation element in cooling water tank 100 adopted is many radiating ribs that are distributed on cooling water tank 100 madial walls, described radiating ribs starts to extend to relative inwall from the inwall that cooling water tank 100 is used for fixed L ED aluminium base 500 1 sides, and many radiating ribs arrangements parallel to each other.A large amount of radiating ribs is the radiating efficiency of heat radiation water tank 100 to a great extent.Simultaneously, also can carry out improving radiating effect by changing cooling water tank 100 materials own.
Preferably, as shown in Figure 1, being respectively equipped with the first water tank end cap 102 and the second water tank end cap 103, the first water tank end caps 102 on the relative both ends of the surface of cooling water tank 100 offers respectively for the first through hole and the second through hole (figure does not illustrate with label) that connect the first water pipe 200 and the second water pipe 300 with being connected on water tank end cap 103.It should be noted that, if the first water tank end cap 102 or the second water tank end cap 103 adopt dismountable mode to be connected with cooling water tank 100, also should adopt seal approach between the end face of the first water tank end cap 102 or the second water tank end cap 103 and cooling water tank 100, for example add sealing ring.The first water pipe 200 or the second water pipe 300 can adopt joint fastening nut and joint clamp nut to be communicated with the end face of cooling water tank 100, in this case, also should be noted that the sealing between water pipe and cooling water tank 100, seal such as employing end cap seal circle etc.
In a preferred embodiment of the invention, above-mentioned water circulation Control Component 600 comprises is located at water pump 602 on the second water pipe 300, that be used for controlling the magnetic valve 601 of current break-make and be used for controlling water flow, and magnetic valve 601 and water pump 602 are electrically connected with control circuit board respectively.That is to say, when the temperature in cooling water tank 100 reaches certain value, control circuit board is controlled magnetic valve 601 and is opened, make between cooling water tank 100 and extraneous water environment and form water circulation, when temperature further promotes, control circuit board will be opened water pump,, to improve the flow of current, increase the speed of water circulation.
Further, above-mentioned fixed head 401 can adopt ellipse or circular fixed head.And in the present invention, fixed head 401 is oval-shaped fixed head, and this oval-shaped fixed head can be rotatably set in the surface of cooling water tank 100 by the fixed axis that departs from oval fixed head center., because oval-shaped fixed head 401 has major axis and minor axis, therefore when with minor axis, partly being fixed, can fix large-sized LED aluminium base 500, and when adopting major axis partly to be fixed, can fix slightly undersized LED aluminium base 500.Oval-shaped fixed head 401 is further strengthened the versatility of this water circulation automatic heat radiation frock.
In the present invention, what temperature-sensitive element adopted is thermosensitive probe, and control circuit board belongs to those skilled in the art's known techniques to the control of magnetic valve 601 and water pump 602, therefore, anyly realizes that the control circuit board of the object of the invention all can be used in the present invention.
Above embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement accordingly, can not limit the scope of the invention.All equalizations of doing with the claims in the present invention scope change and modify, and all should belong to the covering scope of the claims in the present invention.
