Bipolar transistor) module, diode (led) module etc..There is cooling passage in aforesaid substrate 40 and the cooling passage is positioned at above-mentioned
The lower section of hyte, and the coolant by being flowed in cooling passage are installed, take away the heating module work for being fixed on installation position
Heat caused by work.Above-mentioned cooling passage includes the first cooling section 41 and the second cooling section 42, and the He of the first cooling section 41
Second cooling section 42 sequentially passes through the lower section of all installation positions 45 of installation hyte, and the coolant in the first cooling section 41 respectively
Flow through the lower section of all installation positions 45 of an installation hyte successively with the first order；Coolant in second cooling section 42 is with
Two orders flow through the lower section of all installation positions 45 of an installation hyte successively；Wherein, the first order and the second order are opposite.
Such as in Fig. 4, the coolant in the first cooling section 41 flows through three installation positions 45 successively by the order of upper, middle and lower；
Coolant in second cooling section 42 under, in, on order flow through three installation positions 45 successively.
Especially, to simplify cooling passage design, the first cooling section 41 and second of each lower section of installation position 45 can be made
The flow direction of coolant in cooling section 42 in the lower section of each heating module 45 on the contrary, there is two bursts of coolants of reverse flow.
With existing radiator similarly, to improve radiating efficiency, can divide in the first cooling section 41 and the second cooling section 42
The radiating fin set along coolant flow direction is not set.Not influence flow resistance, the first cooling section 41 and the second cooling section 42
Radiating fin there is identical density, and size is consistent.
In the first cooling section 41 and the second cooling section 42, temperature raises successively after coolant is flowed through below heating module,
By cold fluid and hot fluid cross flow one, can solve the problems, such as heating module samming before and after series connection water route.
Especially, the head end of above-mentioned second cooling section 42 is connected to the tail end of the first cooling section 41, the first cooling section 41
Head end connects the inlet 43 of the cooling passage, and the tail end of the second cooling section 42 connects the liquid outlet 44 of cooling passage,
I.e. inlet 43 and liquid outlet 44 are respectively positioned on the side of the installation position 45 of the top.Certainly, in actual applications, the first cooling section
41 and second cooling section also can be independent mutually, i.e. the both ends of the first cooling section 41 connect inlet and liquid outlet, second cold respectively
But the both ends of section 42 also connect inlet and liquid outlet respectively.It is uniform to reach gentle flow resistance, the above-mentioned He of first cooling section 41
Second cooling section 42 can have identical caliber.
Now, it is assumed that coolant is a DEG C in the temperature of inlet 43, and accumulated temperature is b DEG C when flowing through half of heating module, then most
