Definitions

  • the invention relates to a perpendicular flow type filter element according to the preamble of claim 1.
  • the invention also relates in particular to an air conditioning system with such a perpendicular flow type filter element.
  • Heat exchangers of this type are known from the publications DE 10 2019 210022 A1 and CN 103727706 A . Filter elements of the above-mentioned type are described in the publications DE 10 2011 102 899 B4 , KR 20060090856 A , EP 3 708 928 A1 , EP 3 671 068 A1 , and EP 2 587 194 A1 .
  • a disadvantage of these filter elements is that they are of relatively large construction and furthermore have a small effective filter surface, so that particles, in particular microparticles from the production, which can impact the function of the heat exchanger at least long-term, can remain in a fluid flow, which flows through the heat exchanger.
  • the object of the invention lies therefore in providing an enhanced filtering of the said fluid flow.
  • a heat exchanger comprising at least one such filter element is to also be specified.
  • the basic idea of the invention lies in providing a filter element with relatively large filter surface with low package requirements.
  • a filter element of the perpendicular flow type for a component used in an air conditioning system of a vehicle or in an air conditioning system including or realizing a heat pump of a vehicle which has a hollow cylinder body, through which a fluid flow of fluid, in particular refrigerant, can flow, and which extends along a central longitudinal axis, a base body, and a filter body, through which the fluid flow can flow and which is arranged on the hollow cylinder body, for filtering the fluid flow.
  • the hollow cylinder body limits a flow channel for fluid, which has a flow region, through which the fluid flow can flow or flows in parallel or essentially in parallel with respect to the central longitudinal axis, and a further flow region, through which the fluid flow can flow or flows perpendicularly or essentially perpendicularly with respect to the central longitudinal axis.
  • fluid can thus flow into the perpendicular flow type filter element, for example initially perpendicularly with respect to the central longitudinal axis, and can then subsequently flow out of the perpendicular flow type filter element in parallel with respect to the central longitudinal axis, or vice versa.
  • the flow region can thereby advantageously be a fluid outlet region, and the further flow region can be a fluid inlet region.
  • the base body is formed integrally with the hollow cylinder body at least in some sections, and has a fixing means and a sealing means assembly, by means of which the perpendicular flow type filter element can be fixed in a releasable and fluid-tight manner to the component, in particular to said outlet flange of the heat exchanger.
  • An advantageous perpendicular flow type filter element is thereby specified, in the case of which a fixing means and a sealing means assembly are formed on the base body, so that corresponding means do not have to be provided on the hollow cylinder body and filter body, and sufficient installation space for a relatively large filter surface remains.
  • the specified filter element in particular also has the advantage that particles entrained in the fluid flow, in particular also microparticles, can be separated, so that damages especially to a heat exchanger, in which the perpendicular flow type filter element according to the invention can be installed in its state of use, or to the components thereof (for example a compressor and/or an expansion valve), which are usually caused by these particles, can be prevented reliably.
  • a further advantage of the invention is that all components, especially the heat exchanger, are well protected. Further, the said filter element is specially designed to filter out residual dirt from the fluid in the outlet of the component.
  • the hollow cylinder body can advantageously have a round, oval, or angular, in particular rectangular or square, cylinder ring base area.

It can in particular be installed on an outlet flange of the component, especially the heat exchanger, in only a single operating step, so that the initial installation as well as service work following later on the perpendicular flow type filter element are possible quickly and cost-efficiently.
  • the hollow cylinder body has a front-side outlet axial opening and that, on the axial end or in the region of the axial end, the hollow cylinder body furthermore has a sealing lip, which revolves in a closed manner around the central longitudinal axis and which is arranged on the outer circumferential side on a circumferential wall of the hollow cylinder body, for sealing the perpendicular flow type filter element with respect to an outlet flange of the component, especially the heat exchanger.
  • the hollow cylinder body can furthermore have at least one inlet circumferential opening, which penetrates the circumferential wall.
  • the filter body is arranged on the circumferential wall, spanning the at least one inlet circumferential opening, and, in a state of use of the perpendicular flow type filter element, in which the perpendicular flow type filter element is advantageously arranged on the outlet flange of the component, especially heat exchanger, can be or is flown through by the fluid flow transversely with respect to the central longitudinal axis.

  • the hollow cylinder body and the sealing lip can in particular be molded in a common operating step and can thus be provided relatively cost-efficiently.
  • said filter body completely spans or covers, respectively, the at least one inlet circumferential opening, so that said fluid flow has to flow completely through the filter body without any detours. As a whole, it can be ensured with these measures that, in the state of use of the perpendicular flow type filter element, the fluid flow does in fact flow completely through the filter body and does not flow past the latter.
  • the base body is designed cylindrically, in particular in round-cylindrically, and has an outer circumferential surface, on which the sealing means assembly for sealing the perpendicular flow type filter element is arranged or formed.
  • Said fixing means can furthermore be arranged or formed on the outer circumferential surface of the base body.
