Abstract
Abstract An apparatus for securing assembly plates in washing or spraying installations of heat exchangers, particularly cooling towers, with at least two layers of vertical assembly plates, with the layers being disposed one above the other and the assembly plates in each layer, respectively, being arranged parallel to one another, and from layer to layer at a predetermined spacing as well as at a predetermined angle with respect to each other. A spacer is arranged diagonally to the angularly crossing assembly plates, which spacer is provided with lower and upper guide slots under the circumstances oriented at half the crossing angle with respect to its longitudinal extent. The guide slots of each set run parallel to one another. The upper and lower guide slots respectively run in the crossing angle relative to each other and have contact surfaces respectively formed spaced apart corresponding to the predetermined spacing of the assembly plates of the layers which are disposed one above the other.

Claim 1
Independent Claim
187 words
An apparatus for securing of assembly plates in spraying installations of heat exchangers, particularly cooling towers, with at least two layers of vertical assembly plates, which layers are disposed one above the other, the assembly plates in each layer respectively being arranged parallel to each other, and from layer to layer are arranged at a predetermined spacing as well as at a predetermined angle with respect to one another, comprising a spacer defining a longitudinal extent and adapted to be arranged diagonally relative to the angularly crossing assembly plates, said spacer including portions forming a plurality of lower guide slots and a plurality of upper guide slots, respectively, said upper guide slots running mutually parallel to each other, said lower guide slots running mutually parallel to each other, said upper guide slots running at a crossing angle relative to said lower guide slots, said portions include contact surfaces, respectively, of said upper and said lower guide slots, respectively, said contact surfaces, respectively being spaced from each other corresponding to the predetermined spacing of the assembly plates of the two layers which are disposed one above the other.
Claim 2
Independent Claim
187 words
An apparatus for securing of assembly plates in spraying installations of heat exchangers, particularly cooling towers, with at least two layers of vertical assembly plates, which layers are disposed one above the other, the assembly plates in each layer respectively being arranged parallel to each other, and from layer to layer are arranged at a predetermined spacing as well as at a predetermined angle with respect to one another, comprising a spacer defining a longitudinal extent and adapted to be arranged diagonally relative to the angularly crossing assembly plates, said spacer including portions forming a plurality of lower guide slots and a plurality of upper guide slots, respectively, said upper guide slots running mutually parallel to each other, said lower guide slots running mutually parallel to each other, said upper guide slots running at a crossing angle relative to said lower guide slots, said portions include contact surfaces, respectively, of said upper and said lower guide slots, respectively, said contact surfaces, respectively being spaced from each other corresponding to the predetermined spacing of the assembly plates of the two layers which are disposed one above the other.
Claim 3
Dependent Claim
87 words
The apparatus as set forth in claim 1, wherein said portions include a plurality of pairs of adjacent spaced guide plates, respectively, each of said pairs of said spaced guide plates forms one of said guide slots between said spaced guide plates thereof, said pairs of said guide plates are spaced from and adjacent to each other, a web is connected to and between adjacent of said pairs, said web is connected to and between adjacent ones of said guide plates of adjacent of said pairs, respectively.
Claim 4
Dependent Claim
32 words
