Header-tank assembly

Abstract

A header-tank assembly for a fluid, including: a header, a cover, a first baffle forming an end wall for a fluid channel at an end of the header, a second baffle including a first opening configured to provide a fluidal communication between the header-tank assembly and a fluid loop, a distribution device located between the first baffle and the second baffle, the distribution device including a first open end and a second open end. The first open end of the distribution device is in a contact with the first baffle and the second open end is fluidly connected with the first opening of the second baffle. The first baffle includes a sealing portion configured to be fixed to the first open end of the distribution device to form a fluid-tight connection blocking the exit of the fluid from the first open end of the distribution device.

What is claimed is: 
     
         1 . A header-tank assembly for a fluid, comprising:
 a header including a plurality of openings to receive tubes,   a cover configured to be assembled with the header to form a channel for the fluid,   a first baffle forming an end wall for the fluid channel for the fluid at an end of the header,   a second baffle including a first opening configured to provide a fluidal communication between the header-tank assembly and a fluid loop,   a distribution device located between the first baffle and the second baffle, the distribution device including a first open end and a second open end, wherein the first open end of the distribution device is in a contact with the first baffle and the second open end is fluidly connected with the first opening of the second baffle,   wherein   the first baffle includes a sealing portion configured to be fixed to the first open end of the distribution device to form a fluid-tight connection blocking the exit of the fluid from the first open end of the distribution device.   
     
     
         2 . The header-tank assembly according to  claim 1 , wherein the distribution device is of tubular shape. 
     
     
         3 . The header-tank assembly according to  claim 1 , wherein the sealing portion surrounds an outer perimeter of the first open end of the distribution device. 
     
     
         4 . The header-tank assembly according to  claim 1 , wherein the first open end of the distribution device surrounds an outline of the sealing portion. 
     
     
         5 . The header-tank assembly according to  claim 1 , wherein the distribution device includes plurality of orifices configured to distribute the fluid. 
     
     
         6 . The header-tank assembly according to  claim 1 , wherein the distribution device includes a dent configured to facilitate insertion the distribution device to the first baffle. 
     
     
         7 . The header-tank assembly according to  claim 1 , wherein the distribution device includes a bevelled end configured to facilitate fixing the distribution device to the first baffle. 
     
     
         8 . The header-tank assembly according to  claim 1 , wherein the sealing portion is made integral with the first baffle. 
     
     
         9 . The header-tank assembly according to  claim 1 , wherein the header includes two parallel rows of slots configured to receive tubes. 
     
     
         10 . The header-tank assembly according to  claim 1 , wherein the header-tank assembly includes two pairs of baffles, each pair for a cover, the baffles of a pair are configured to be located at the opposite ends of the cover. 
     
     
         11 . The header-tank assembly according to  claim 1 , wherein the first baffle includes a portion being substantially perpendicular the general axis of elongation of the distribution device. 
     
     
         12 . The header-tank assembly according to  claim 1 , wherein the sealing portion includes a sloping portion configured to form an additional orifice at least in-line with the outline of the sealing portion. 
     
     
         13 . The header-tank assembly according to  claim 1 , wherein the sealing portion includes a semi-spherical portion configured to form an additional orifice at least in-line with the outline of the sealing portion. 
     
     
         14 . The header-tank assembly according to  claim 1 , wherein the baffle is made of the same material as the header. 
     
     
         15 . A heat exchanger comprising at least one header-tank assembly including:
 a header including a plurality of openings to receive tubes,   a cover configured to be assembled with the header to form a channel for the fluid,   a first baffle forming an end wall for the channel for the fluid at an end of the header,   a second baffle including a first opening configured to provide a fluidal communication between the header-tank assembly and a fluid loop,   a distribution device located between the first baffle and the second baffle, the distribution device including a first open end and a second open end, wherein the first open end of the distribution device is in a contact with the first baffle and the second open end is fluidly connected with the first opening of the second baffle,   wherein   the first baffle includes a sealing portion configured to be fixed to the first open end of the distribution device to form a fluid-tight connection blocking the exit of the fluid from the first open end of the distribution device.
