Abstract
A heat exchanger for a heating, ventilation and/or air-conditioning device including a thermal loop equipped with a heat exchanger, is characterized in that at least one of the first and second longitudinal ends (92) of at least one partition plate (20) and/or of at least one end plate (9) is coupled to at least one of the first and second ends of a said orientation plate (2, 20) by means of a damper element (94, 95).
Claims16
A heating, ventilation and/or air-conditioning device including a thermal loop equipped with a heat exchanger, the heat exchanger comprising:
- a stack of orientation plates having first and second opposite longitudinal ends defining channel regions between them in which a cooling liquid travels from one said end to the other in a longitudinal direction of the orientation plates,
- the first and the second longitudinal ends of the orientation plates having means for directing a flow of the cooling liquid either in an axial direction of the heat exchanger or, by diverting it, in the longitudinal direction of the orientation plates, in said channel region,
- certain orientation plates being axial-orientation plates, and certain orientation plates being partition plates which, at least at one of their ends, divert the flow of the cooling liquid into said channel region,
- the heat exchanger also having end plates arranged at its two opposite axial ends,
- wherein a one of the longitudinal ends of at least one of the orientation plates is coupled by means of at least one damper element to a corresponding end of at least one other of the orientation plates and/or at least one of the end plates,
- wherein at least one said damper element is integral with a stiffening means.
A heating, ventilation and/or air-conditioning device with a heat exchanger, the heat exchanger comprising:
- a pair of end plates defining axial ends of the heat exchanger;
- and
- a plurality of stacked plates comprising
- (1) at least one standard plate having (a) an aperture formed in a bottom of at least one axially extending boss, the aperture configured to permit axial flow and (b) a recessed longitudinal channel configured to permit longitudinal flow, and
- (2) at least one partition plate having a separating wall disposed adjacent to the aperture of the at least one standard plate;
- wherein at least one other separating wall couples together with at least two of the stacked plates at a closed end defined where at least one of the apertures is adjacent to the separating wall or the end plate, and wherein the heat exchanger further comprises a plurality of ribs carried by the at least one other separating wall.
A heating, ventilation and/or air-conditioning device with a heat exchanger, the heat exchanger comprising:
- a pair of end plates defining axial ends of the heat exchanger;
- and
- a plurality of stacked plates comprising
- (1) at least one standard plate having (a) an aperture configured to permit axial flow and (b) a recessed longitudinal channel configured to permit longitudinal flow, and
- (2) at least one partition plate having a separating wall disposed adjacent to the aperture of the at least one standard plate;
- wherein at least one other separating wall couples together with at least two of the stacked plates at a closed end defined where at least one of the apertures is adjacent to the separating wall or the end plate, and wherein the at least one other separating wall further comprises a stiffening plate interposed between the end plate and the closed end, the end plate being coupled to the stiffening plate through an axially extending boss.
A heating, ventilation and/or air-conditioning device including a heat exchanger, the heat exchanger comprising:
- a plurality of orientation plates comprising (1) at least one standard plate having (a) an aperture configured to permit axial flow and (b) a recessed longitudinal channel configured to permit longitudinal flow, (2) at least one partition plate having a separating wall disposed adjacent to the aperture of the at least one standard plate;
- a pair of end plates arranged at opposing axial ends of the orientation plates;
- and
- at least one boss extending from a one of the end plates and configured to dampen vibration transmission from an adjacent orientation plate,
- wherein a one of the partition plates is adjacent to the end plate, and wherein the at least one boss comprises a one of the partition plates interposed between an adjacent partition plates and the end plate.
