Definitions
- This invention relates to heat exchangers field designed especially for cooling or heating of battery cells (accumulators), which are aligned next to each other and/or above each other and creates battery module that is used as power source for example in electric vehicles.
- battery cells accumulators
- thermoly regulated fluid flows.
- Such a heat exchanger is known e.g. from patent PV 2018-192, describing heat exchanger module for battery cells which is composed at least one polymeric hollow fiber row that are connected with inlet tank on one end and with outlet tank on the other end of fibers. Individual polymeric hollow fiber rows are oriented perpendicularly to battery cell axis and are placed into free space between battery cells. Polymeric hollow fiber row is connected to tank via flange which also creates pressure on gasket placed on the polymeric hollow fiber row and inserted in groove of tank. Inlet and outlet tank with flange are made from plastic for elimination of electric shortcut, weight reduction and avoidance of thermal loss in inefficient area in case of placing heat exchanger into battery module.
- Such a heat exchanger are directly dependent on the arrangement and number of battery cells in the battery module, where the length of polymeric fibers grow when the number of battery cells in a row increases, whereby dimensions of tanks and flanges are unchanged.
- Object of this invention is to create alternative of plastic heat exchanger that will allow distribution of fluid from one side of heat exchanger only, on which the inlet and outlet tanks will be placed. This will free up space for the installation of more battery cells in the battery module and the heat exchanger will be provided with a degas spout to ensure proper fluid filling.
- a heat exchanger with a double manifold whose essence is one double manifold with two integrated channels for inlet and outlet of fluid that is composed from inlet tank, several types of manifold components and outlet tank.
- the heat transfer surface is formed by hollow polymeric fibers rows which are guided around each row of battery cells and which connect the two channels in the manifold to form the final heat exchanger.
- One of the manifold components is provided with degas spout that is positioned in the highest place of heat exchanger after installation to battery module, is part of one of integrated channels and allows correct and complete filling of the heat exchanger with liquid.
- Each row of polymeric hollow fibers is provided with gasket on both ends which is inserted between two consecutive parts of double manifold (tank or manifold component) into grooves and by joining of those two parts sealing is achieved. Individual parts of double manifold can be joined by gluing, welding or other mechanical joint.
- the invention will be further clarified by means of examples of a possible double manifold heat exchanger design for battery cells.

- battery cells 7 are placed, which are arranged in rows perpendicular to the of polymeric hollow fibers rows 6.
- Joint of polymeric hollow fibers rows 6 with double manifold is shown in section on Fig. 2 and is formed from a gasket 9, which are applied to the edges of the polymeric hollow fibers rows 6_and are inserted into the grooves on the inlet tank l j manifold components 2, 3 and 4, and outlet tank 5, and then sealed by joining the parts together that will create double manifold with two integrated channels.
- the joint is formed e.g. by gluing or by vibration welding.
- FIG. 3 Joint of polymeric hollow fibers rows 6 into both integrated channels in created manifold is shown by two cross sections on Fig. 3, wherein the upper section goes through contact surface between the manifold component 2 with degas spout 8 and manifold component 3, that is not shown in section.
- the lower section goes through contact surface between manifold component 4 and manifold component 3, that is not shown in section.
- the upper section shows inlet into polymeric hollow fibers rows 6 and placing between battery cells 7.
- the lower section shows outlet from polymeric hollow fibers rows 6 and more precisely specifies the location between the battery cells 7.
- Fig. 5 is shown similar type of heat exchanger with double manifold assembled from four polymeric hollow fibres rows 6, whose both ends are connected with a double manifold that is formed by inlet tank 1, seven symmetrical manifold components 11 and outlet tank JO with two outlet spouts from one integrated channel, whereby those outlet spouts shapes don't need to be equal and the spout placed higher can be used as degas spout during filling fluid as well.
- the battery cells 7 are placed, which are arranged in rows perpendicular to the of polymeric hollow fibers rows 6.
- Joint of polymeric hollow fibers rows 6 with double manifold is shown in section on Fig. 6 and is similar to the first example. Again, it is formed from gasket 9, which are applied to the edges of the polymeric hollow fibers rows 6 and are inserted into the grooves on the inlet tank 1, symmetrical manifold components 11 and outlet tank 10 with two outlet spouts and then sealed by joining those parts together, that will create double manifold with two integrated channels. On the contact surfaces of the inlet tank 1 , symmetrical manifold components 11, and outlet tank 10 with two outlet spouts the joint is formed e.g. by gluing or by vibration welding.
- a single manifold component type ll j whose two axonometric views are shown in FIG. 8, is possible due to its symmetrical shape.
- Two symmetrical manifold components 11 side by side are rotated 180 ° to each other and create part of double manifold with two integrated channels.
- Joint of polymeric hollow fibers rows 6 into both integrated channels in formed double manifold with outlet tank 1 ⁇ that has two outlet spouts is shown in two sections on Fig. 9, wherein the upper section goes through contact surface between the symmetrical manifold components 11 and is oriented towards the outlet tank 10 with two outlet spouts.
- the lower section goes through the same contact surface of symmetrical manifold component 11 and is oriented towards the inlet tank 1.
- the upper section shows outlet from polymeric hollow fibers rows 6 and placing between battery cells 7,
- the lower section shows inlet into polymeric hollow fibers rows 6 and more precisely specifies the location between the battery cells 7.
