Definitions
- the present invention relates to a heat exchanger provided with one or more cooling flow guide baffles for optimum heat exchange between cooling fluid and cooled fluid.
- the automotive sector is known for heat exchangers which include:
- At least one column of parallel tubes of rectangular section arranged in a stack which define a longitudinal direction;
- the cooling fluid is forced through said passage sections into contact with the outer surface of the tubes, so that a heat exchange occurs between the fluid to be cooled which passes through the inside of the tubes and the cooling fluid.
- cooling fluid baffles which consist of obstacles which are provided in the passage sections in order to configure the flow more efficiently.
- a heat exchanger that includes:
- At least one column of stacked parallel tubes which define a longitudinal direction
- Coolant baffles characterized in that the baffles are at least two integral lamellar bodies arranged in a plane perpendicular to the longitudinal direction and cut so that each has:
- a first section capable of partially blocking a passage section between tubes and casing
- each of the lamellar bodies being such that the extensions of one of the lamellar bodies overlap with the extensions of the other lamellar body, so that each lamellar body can be introduced laterally relative to the tubes and constitute a deflector of the cooling fluid.
- the tubes are provided on their upper and lower sides with protuberances intended to keep the tubes assembled together and with the housing.
- the tubes are of rectangular section.
- the exchanger comprises two contiguous columns of parallel tubes of rectangular section arranged in a stack.
- each lamellar body comprises an end section parallel to the extensions and which obstructs the cooling fluid passage section between the housing and the lower or upper tube of the stack.
- the end section of the lamellar bodies comprises cutouts adapted to cooperate with the protuberances of the housing.
- the exchanger comprises an upper frontal cooling fluid inlet and a rearward lateral cooling fluid outlet, two lamellar bodies arranged to obstruct the cooling fluid passage section through the upper part immediately downstream of the upper front cooling fluid inlet and two lamellar bodies arranged to obstruct the cooling fluid passage section through the lower portion immediately upstream of the lateral rearward cooling fluid outlet.
- each of the first sections comprises cheeks that extend perpendicularly from their contact edge with the tubes, so that they constitute plates for fixing to the tubes.
- Figure 1 is an elevational section of the exchanger according to the invention.
- FIG. 2 is an exploded perspective view of the exchanger according to the invention.
- Figure 3 is a front view.
- Figures 4 and 5 are side elevations and front views of one of the unitary parts that constitute the deflector means.
- Figure 6 is an exploded perspective view of a set of tubes and two pairs of baffle pieces.
- the invention relates to a heat exchanger 1 which comprises:
- Coolant deflectors 6 and 7 characterized in that the deflectors are at least two lamellar bodies 6, 7 in one piece arranged in a plane perpendicular to the longitudinal direction and cut so that each has:
- a first section 8 capable of partially blocking a section 5 for passage between tubes and casing 3,
- the baffles are made of two pieces which have a comb shape and are assembled by the sides by introducing the teeth of the comb between the tubes 2. The ends of these "combs" are superimposed to constitute the equivalent of a single piece.
- the tubes 2 are provided on their upper and lower sides with protuberances P intended to hold the tubes 2 assembled together and with the housing 3.
- the exchanger comprises two contiguous columns of parallel tubes 2 of rectangular section arranged in a stack.
- the cross section between contiguous tubes in the horizontal direction is not blocked by the pieces or "combs", but it is a section of little importance.
- Each lamellar body 6, 7 comprises an end section 10 parallel to the extensions 9 and which obstructs the section of cooling fluid passage between the housing 3 and the lower or upper tube of the stack.
- This terminal section 10 can be welded to the upper (lower) surface of the upper (lower) tube to help secure the baffles to the tubes.
- the exchanger comprises an upper front inlet 1 1 of cooling fluid and a rear lateral outlet 12 of cooling fluid, two lamellar bodies 6, 7 arranged to obstruct the cooling fluid passage section through the upper part immediately downstream of the upper front inlet 1 1 of cooling fluid and two lamellar bodies 6 ', 7' arranged to obstruct the cooling fluid passage section through the lower portion immediately upstream of the rear lateral outlet 12 of cooling fluid.
- Figure 1 can be discerned the general change in the flow of cooling fluid that is obtained with the two pairs of deflector parts. Of course, any combination of deflector parts can be used to achieve the desired flow.
- Each of the first sections 8 comprises cheeks 13 which extend perpendicularly from their edge of contact with the tubes, so that they constitute lateral attachment plates to the tubes 2.
- the parts which constitute the baffles comprise cutouts 14 intended to allow the inner protuberances of assembly of the housing to pass, since the assembly thereof is made by sliding over the assembly once the baffles are placed on the tubes and fixed. to these.
- the parts cover between half and two thirds of the passage section, although we can in each case determine the number of pairs of optimal parts to obtain the flow of desired cooling fluid.
