Heat exchanger

摘要

The invention relates to a heat exchanger for heat exchange between fluids, comprising a housing having an inlet and an outlet for each fluid, the inlet and outlet for each fluid being connected to one another by a flow path, the flow path of a first fluid comprising multiple heat exchange modules comprising at least one longitudinal hollow tube, wherein the modules are arranged in a matrix configuration that comprises at least two columns of longitudinal tubes and at least two rows of longitudinal tubes, and wherein a module is provided with at least one connector for connecting to a co-operating connector of an adjacent module, such that the space enclosed between adjacent modules defines a flow path for a second fluid, parallel to the flow path for the first fluid.

1. A heat exchanger for heat exchange between fluids, the heat exchanger comprising a housing having an inlet and an outlet for each fluid, the inlet and the outlet for each fluid being connected to one another by a flow path, the flow path of a first of the fluids comprising multiple heat exchange modules comprising at least one longitudinal hollow tube, wherein the modules are arranged in a matrix configuration that comprises at least two columns of longitudinal tubes and at least two rows of longitudinal tubes, and wherein each module is provided with at least one integral connector for connecting to a co-operating connector of an adjacent module, such that the space enclosed between adjacent modules defines a flow path for a second of the fluids, parallel to the flow path for the first fluid, wherein each connector substantially extends over the whole length of the associated module parallel to longitudinal axis of a longitudinal tube thereof, and the connectors are connected to each other substantially over the whole length of the associated modules such that the matrix configuration is a self-supporting arrangement, and wherein the modules are made from plastic material, and wherein the at least one integral connector of each module comprises at least one of a male connector and a female connector, the male connectors of the modules co-operating with the female connectors of the modules by means of at least one of a snap fit or a slide fit;
further comprising a first distributor for connecting the inlet for the first fluid to the flow path for the first fluid, and a first collector for connecting the flow path for the first fluid to the outlet for the first fluid; wherein the first distributor comprises a first distributing chamber at a first end of the housing defined by a first end wall of the housing, a first panel spaced apart from said first end wall and corresponding side wall sections of the housing, and wherein the first collector comprises a first collector chamber at a second end of the housing opposite to the first end, the first collector chamber being defined by a second end wall of the housing opposite to the first end, a second panel spaced apart from said second end wall and corresponding side wall sections of the housing, and wherein the first panel and the second panel are provided with a plurality of through bores corresponding to the total number and positions of the longitudinal tubes, the longitudinal tubes extending through the through bores of the first panel and the second panel so as to establish a fluid communication with the first distributing chamber and the first collector chamber; and further comprising a second distributor for connecting the inlet for the second fluid to the flow path for the second fluid, and a second collector for connecting the flow path for the second fluid to the outlet for the second fluid, wherein at both ends of the longitudinal tube of each module, the ends of the connectors facing the first and second panel are situated at a distance from the first and second panel, and wherein the second distributor comprises a second distributing chamber at said second end of the housing defined by the second panel, the ends of the connectors facing the second panel and being situated at a distance from the second panel, and corresponding side wall sections of the housing, and wherein the second collector comprises a second collector chamber at said first end of the housing defined by the first panel, the ends of the connectors facing the first panel and being situated at a distance from the first panel, and corresponding side wall sections of the housing, the second distributor and the second collector being in fluid communication via the spaces enclosed between adjacent modules defining the flow path for the second fluid.
