(13) The cooling array 100 depicted in FIG. 1 is designed for cooling of the electronic components 101 and features the electronic component 101.

(14) The electronic component 101 is disposed in a housing 103 of the cooling array 100, which at least partially surrounds the electronic component 101. In FIG. 1, the housing 103 is only shown sectionally. The housing 103 features a housing opening 105. The housing 103 can be in particular part of a cup housing for accommodating a fluid container, so that a particularly effective fluid-tight enclosure of the electronic component 101 within the housing 103 is provided. In one form, the housing 103 is formed in particular at least partially from a plastic material.

(15) The electronic component 101 is disposed within the housing 103 on a support element 107.

(16) The cooling array 100 furthermore comprises a heat sink support 109 which is connected to the housing 103, wherein the heat sink support 109 is accommodated in particular at least partially within the housing opening 105 of the housing 103.

(17) In one form, the heat sink support 109 is formed in particular at least partially from a plastic material.

(18) According to the teaching of the present disclosure, a fluid-tight connection between the heat sink support 109 and the housing 103 is present in order to inhibit the ingress of fluid to the electronic component 101.

(19) The fluid-tight connection between the heat sink support 109 and the housing 103 comprises at least one of the following connections: a materially-bonded connection, in particular a welded connection and/or a glued connection; a friction-locking connection, in particular a screw connection or a snap connection; and/or a form-fitting connection, in particular a clip connection and/or a caulked connection.

(20) With normal requirements for fluid-tightness, the fluid-tight connection between the heat sink support 109 and the housing 103 can comprise in particular a friction-locking connection, in particular a screw connection or a snap connection, and/or a form-fitting connection, in particular a clip connection and/or a caulked connection.

(21) For particularly strict requirements for fluid-tightness, the fluid-tight connection between the heat sink support 109 and the housing 103 can be in particular a materially-bonded connection, in particular a welded connection and/or a glued connection.

(22) For particularly strict requirements for fluid-tightness, a sealing element—not depicted in FIG. 1—can be disposed in particular between the heat sink support 109 and the housing 103, which comprises in particular a labyrinth seal and/or a two-component seal. In one form, a corresponding sealing element can in particular comprise at least partially silicone.

(23) The cooling array 100 further comprises a heat sink 111, which is accommodated within the heat sink support 109. The heat sink 111 is thermally coupled to the electronic component 101 in order to disperse heat generated by the electronic component 101. The heat sink 111 is formed in particular at least partially from a metal or a metal alloy, in particular aluminum.

(24) In particular, the heat sink 111 is inserted into the heat sink support 109 perpendicularly to the lateral extension of the electronic component 101.

(25) Upon insertion of the heat sink 111, a tolerance compensation can be provided for the heat sink support 109.

(26) In particular, the heat sink 111 is connected in a materially-bonded manner, in particular molded, with the heat sink support 109, or the heat sink 111 is connected to the heat sink support 109 in a form-fitting or friction-locking manner.

(27) The cooling array 100 further comprises a thermally conductive intermediate layer 113 which is disposed between the electronic component 101 and the heat sink 111, in particular between the electronic component 101 and the heat sink support 109. The thermally conductive intermediate layer 113 improves in particular the thermal coupling between the heat sink 111 and the electronic component 101. Additionally the thermally conductive intermediate layer 113 provides a tolerance compensation between the heat sink support 109 and the electronic component 101.

(28) In one form, the thermally conductive intermediate layer 113 is formed in particular from an elastic material.

(29) In summary, it can be noted that the heat generated by the electronic component 101 can be conducted to the heat sink 111 via the in particular thermally conductive intermediate layer 113, via the heat sink support 109, wherein the heat sink 111 disperses or radiates the heat conducted thereto. In particular, the heat sink 111 hereby features a plurality of cooling fins 115, through which the conducted heat can be radiated in a particularly effective manner. The heat sink 111 depicted in FIG. 1 is hereby formed in particular as an extruded section, which provides a cost-effective production of the heat sink 111.

(30) As can be seen from FIG. 1, the heat sink support 109 is formed as a heat sink support tray 117, which features a tray base 117-1, on which a heat sink underside 111-1 of the heat sink 111 rests, and which features a tray side wall 117-2 which at least partially surrounds the tray base 117-1, on which a heat sink lateral side 111-2 of the heat sink 111 rests.

(31) In order to provide the heat transfer through the tray base 117-1 of the heat sink support tray 117, the tray base 117-1 features in particular a reduced thickness in comparison to the tray side wall 117-2.

(32) In order to provide the fluid-tight connection between the heat sink support 109 and the housing 103, the tray side wall 117-2 is connected to the housing 103 in a fluid-tight manner.

(33) In particular, the tray side wall 117-2 hereby features a contact flange 119 which rests on the housing 103, in particular on a contact rib 121 of the housing 103 surrounding the housing opening 105. The contact flange 119 is hereby connected to the housing 103, in particular to the contact rib 121 in a fluid-tight manner.

(34) With the heat sink array 100 depicted in FIG. 1, the advantage is achieved that only one fluid-tight sealing location must be designed between the heat sink support 109 and the housing 103, whereas there does not need to be any fluid-tight seal between the heat sink support 109 and the heat sink 111.

(35) Additionally, no machining of the heat sink 111 is needed in the heat sink array 100 depicted in FIG. 1, but rather an effective installation of the heat sink 111 into the heat sink support 109 can be achieved due to the tolerance compensation.

(36) FIG. 2 shows a perspective depiction of a cooling array according to a second exemplary form.

(37) The cooling array 100 depicted in FIG. 2 according to the second exemplary form corresponds to the cooling array 100 depicted in FIG. 1 according to the first exemplary form, wherein however the housing 103 in FIG. 2 is only depicted schematically, and wherein the electronic component 101 is not depicted in FIG. 2.

(38) Due to the design of the heat sink support 109 as a heat sink support tray 117, the heat sink 111 accommodated in the heat sink support tray 117 can be formed as an economically producible extruded section, whereby the costs can be reduced.

(39) For additional details refer to the discussion regarding FIG. 1.

(43) The frame groove 125 is bounded by a first groove wall 127-1 and by a second groove wall 127-2 of the heat sink support frame 123. The first groove wall 127-1 rests on a heat sink underside 111-1 of the lateral tab 111-3 of the heat sink 111. The second groove wall 127-2 rests on a heat sink topside 111-4 of the lateral tab 111-3 of the heat sink 111.

(44) The heat sink 111 depicted in FIG. 3 is manufactured from a cast component.

(45) As can be seen in FIG. 3, the thermally conductive intermediate layer 113 is affixed directly to the heat sink 111 and thus makes possible a particularly advantageous thermal conductivity between the electronic component 101 and the heat sink 111, so that a high degree of cooling performance can be provided by the cooling array 100.

(46) As can be seen in FIG. 3, the heat sink support 109 designed as a heat sink support frame 123 features a contact flange 119 which lies on the housing 103—not depicted in FIG. 3—and thus is connected in a fluid-tight manner, in particular lying on a contact rib 121 of the housing 103 which at least partially surrounds the housing opening 105, and is thus connected in a fluid-tight manner.

(47) For additional details refer to the comprehensive variations in FIGS. 1 and 2.

(48) FIG. 4 shows a perspective depiction of a cooling array according to a fourth exemplary form.

(49) The cooling array depicted in FIG. 4 according to the fourth exemplary form corresponds to the cooling array 100 depicted in FIG. 1 according to the first exemplary form, wherein however the housing 103 in FIG. 4 is only depicted schematically, and wherein the electronic component 101 is not depicted in FIG. 4.

(50) The cooling array 100 depicted in FIG. 4 differs from the cooling array 100 depicted in FIG. 1 and FIG. 2 in that the heat sink support 109 which is designed as a heat sink support tray 117 is designed as being a single piece with the housing 103. Thus, the heat sink support 109 and the housing 103 are designed to be integral.

(51) For additional variations refer to the comprehensive variations in FIGS. 1 and 2.

(52) FIG. 5 shows a perspective depiction of a cooling array according to a fifth exemplary variation.
