Problems solved by technology

However, this plate heat exchanger is able to cover a wide range of thermal power, because it meets the needs at high loads, but not at medium loads, because its thermal power decreases with the flow rate of the fluid and the distribution of the plate bundles bad and down

Embodiment Construction

[0049] The following examples are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference refers to the same embodiment or that the feature applies only to a single embodiment. Various features of different embodiments may also be combined and / or interchanged to provide other embodiments.

[0050] In this specification, some elements or parameters may be indexed, eg, a first element or a second element and a first parameter and a second parameter or even a first criterion and a second criterion, and the like. In this case it is just an index used to distinguish and name similar but not identical elements or parameters or criteria. Such indexing does not imply that one element, parameter or criterion takes precedence over another element, parameter or criterion, and such nomenclature may be readily interchanged without departing from the scope of this specification. Nor does this index imply a chronological orde...

Abstract

A thermal energy exchange device (1) comprising a first plate heat exchanger (100) and a second plate heat exchanger (200), each plate heat exchanger (100, 200) being configured to allow the exchange of thermal energy between at least two heat transfer fluids of different temperatures, said exchange device (1) further comprising a distribution member (3) sandwiched between the first plate heat exchanger (100) and the second plate heat exchanger (200), the distribution member (3) comprises a series of channels (31, 32, 33, 34, 35, 36, 37, 38) made inside it, said channels (31, 32, 33, 34, 35, 36, 37, 38) connecting the inlets and outlets of the heat transfer fluid of the first plate heat exchanger (100) and the second plate heat exchanger (200) to connection ports (31a, 32a, 33a, 34a, 35a, 36a, 37a, 38a) located on the distribution member (3).

Description

technical field [0001] The present invention relates to the field of plate heat exchangers. More particularly, the present invention relates to plate heat exchangers in the automotive field. Background technique [0002] In the automotive field, especially in the field of electric or hybrid vehicles, it is known to use the cooling power generated by the air conditioning circuit to cool the battery. To this end, one or more plate heat exchangers allow the exchange of thermal energy between the heat transfer fluid circulating in the battery thermal management loop and the low pressure refrigerant fluid circulating in the air conditioning loop. [0003] Nonetheless, the use of fast battery charging has become critical to the acceptance of electric vehicles. However, the faster the charging process, the higher the current and therefore the more heat to dissipate. The demand for cooling power is therefore greatly increased. The same applies to rapid discharge at high speeds. ...
