Abstract

The invention relates to heat exchangers designed, in particular, for cooling heat-generating electrical elements. The aim of the invention is to improve the maintainability and manufacturability of the heat exchanger for cooling the radio radio elements. In the proposed heat exchanger, when it is perceived by the external surfaces of the heat flux casing, it is transferred inside the housing to the evaporation zone, where all the heat is expended to evaporate the coolant, for example, freon. The heat exchanger reduces cooling water requirements, the use of water chokes, and the use of cheap and affordable raw materials for the manufacture of a condenser. 7 il.

Description

The invention relates to heat exchangers designed, in particular, for cooling heat-generating electrical elements.

The purpose of the invention is to improve maintainability and manufacturability.

Fig, 1 shows the device section; figure 2 - capacitor, cross section; on fig.Z - arterial canal and its cross section; figure 4 - separator; figure 5 - arterial canal, made in the form of a flat segment of the grid; figure 6 - connection of arterial channels: roll - in front, flat - in the back; Fig. 7 shows a vapor discharge channel, a cross section.

The heat exchanger contains a sealed enclosure 1, a condenser 2, a dielectric insert 3, a dispensing manifold 4, a separator 5, coolers 6 g coarse disperse 7 and fine dispersed 8 capillary-porous layers, arterial channels 9 and 10 and rolled in an Archimedes spiral, heat-conducting sheets 11. Dispensing the collector is a system of pipes: central 12, two lateral 13 and three transverse 14 and 15, connected to each other. The rolled arterial canals 9 are connected to both ends of the pipes 14, as well as to the side pipe 13, and the flat arterial canals are connected to both ends of the middle transverse pipe 15.

The heat exchanger operates as follows.

When perceived by the external surfaces of the heat flux housing 1, it is transferred inside the housing to the evaporation zone, where it is consumed to evaporate the heat transfer fluid, for example, freon, from the two-layer cooler 6. Evaporation occurs at the point of contact of the coarse 7 and fine 8 layers with capillary-porous structure The vapor is transferred to the condenser 2, where the pressure is lower, it is condensed, and heat is supplied to the cooling water through the wall 11. The condensate formed along the dispensing collector 4 and the arterial channels 9 and 10 is drained into a two-layer capillary-porous structure.

The proposed heat exchanger reduces the water requirements for cooling water, the application of water chokes, as well as the use of cheap and affordable starting materials for the manufacture of a condenser.
