Title:
COOLING PIPE JOINT STRUCTURE
Document Type and Number:
Japanese Patent JP2012072884
Kind Code:
A
Abstract:

To provide a cooling pipe joint structure for improving cooling efficiency of a water-cooled heat radiation mechanism including a radiation fin and improving cooling capacity of the heat radiation mechanism without increasing the scale of the water-cooled heat radiation mechanism.

In cooling water (Ca) supplied from a water supply pipe 5, cooling water (Ca) flowing into an inner pipe joint 17B is pressurized by a tapered part 172 formed in the inner pipe joint 17B to increase the flow rate and supplied as secondary cooling water (Ca2) to a secondary cooling pipe 12. By accelerating the secondary cooling water (Ca2), the secondary cooling water (Ca2) absorbing heat from a primary cooling pipe 11 where the primary cooling water (Ca1) flows is accelerated and quickly drained in the cooling pipe structure 10, and thereby, reduction in the cooling capacity due to the temperature difference in the primary cooling water (Ca1) can be suppressed.
