The present invention relates to a device for fixing adapter for connecting parts on the heat sink according to the restrictive part of claim 1 of the claims.

A device of this type is known from EP 0401500 A1. This known device has a U-shaped lateral parts with G-shaped straps as a reference and the adjacent parts, which have several facing each other, the wedge-shaped protrusions and which executed elements connecting system that serves for connection of the slats. The side part cover the outside edge of the sink.

From US 5107688 known, for example, a device designed to secure the adapter for connecting parts on the condenser tubes refrigerators, have their back. In such a device with snap fixed two adjacent tubes of the condenser. However, the use of such devices is limited to refrigerators, the capacitors are formed by tubes of circular cross section, which for their retention in this unit must have at least exposed areas.

The present invention was based on the task of developing a device that could reliably and stably be fixed in the Central part of the radiator, which has between its tubes are deformable layer is us.

This task in relation to the device specified in the beginning of the description type is solved according to the invention by means of the characteristics of the characterizing portion of claim 1 claims.

Proposed in the invention, the solution provides a particularly effective samopoczucia mounted on the heat sink device with a relatively small lever arm in the area of its cross-sections with sufficient stability in the zone boundary stations.

In one of the preferred embodiments proposed in the invention device as projections on the transverse sections of the internal protrusions oriented in parallel with the longitudinal extent of the respective cross section of the flat sides. The advantage of this variant is that when docked proposed in the invention device on the heat sink his plate removed primarily in the direction of the longitudinal extent of the transverse sections, allowing for maintenance of strong coupling internal ledges with the fins requires a relatively small effort.

To meet the proposed in the invention device according to this variant, the inner tabs to ensure uniform adhesion of the fins is advisable to make wedge-shaped, symmetrical with respect to the middle line is army.

In another preferred embodiment, the complementary option described above or which is an independent option, as the tabs on the marginal areas of the executed external protrusions oriented in parallel with the longitudinal length of the respective edge area of the flat sides. The advantage of this variant is that when docked proposed in the invention device on the heat sink his plate removed primarily in the direction of the longitudinal extent of the flank areas, allowing for maintenance of strong coupling external lugs with the fins and in this case requires a relatively small effort.

In the latter case some external projections for their effective automatic bonding with the heat sink is made with flat beveled face party.

In this case, some external projections appropriate to comply with curved angle, wedge-shaped beveled end side, which when interconnected supporting parts and mating parts is located opposite to the corresponding external protrusion with a flat beveled face party. This ensures the penetration of external protrusions on the depth of the radiator and thereby a reliable retention of the abutment and the adjacent parts on the radiator.

To follow is eat a preferred embodiment of the proposed invention in a device connector system comprises at least one locking tab and at least one response of the connecting element with hole inserted into it the locking tongue, a locking protrusion, which with the introduction of the locking tongue into the hole in the return of the connecting element engages made for the locking element. This ensures a simple and reliable connection between the supporting parts and mating parts.

To meet the proposed in the invention device according to this variant response of the connecting element has an opening for release with insert of tool retainer latch by removing out of engagement with the corresponding locking element. Thanks to the support piece and the mating part can, if necessary, to easily detach from each other.

In the following a preferred embodiment of the proposed invention the device adapter has a support side, which when interconnected supporting parts and mating parts is located above formed between the support part and the mating component covering the radiator space, and the mating piece has at least two support ribs, which when interconnected supporting parts and mating parts are located on both sides of the adapter, and turned to covering the heat sink space with the of Auron each of which lies in the plane of the reference side of the adapter.

SUBSTANCE: building cradle comprises system including members with support-and-guiding surfaces adapted to temporarily receive support panel for fan engine installation, wherein the support panel is temporarily secured to above support-and-guiding surfaces. The support-and-guiding surfaces are also used to receive support plates to fasten tension bar ends and connection plates arranged between the support plates. Building cradle member for support panel receiving define a circle in plane and has at least one horizontal support-and-guiding surface. Building cradle members for support and connection plates are mainly formed as prisms having trapezoid cross-sections with at least outer inclined face forming support-and-guiding surface to receive support and connection plates of central support member for fan engine installation.

EFFECT: increased manufacturability of gas air-cooling plant production, simplified assemblage, reduced costs and increased reliability and service life of structure to be produced.
