Outer pipe of an outlet of a volute of a heat-transfer pump of a heat engine of a vehicle
The invention relates to an outer pipe ( 1 ) of an outlet ( 4 ) of a volute ( 3 ) of a heat transfer pump ( 2 ), particularly arranged in a recess defined in a heat engine of a vehicle, the outer pipe ( 1 ) being provided on an outer surface ( 9 ) of the cylinder housing ( 8 ) of the engine and comprising a first component ( 5 a ) capable of guiding the heat-transfer fluid from said outlet ( 4 ) to an inlet ( 6 ) of an inner circuit ( 7 ) for circulating the heat-transfer fluid defined in the cylinder housing ( 8 ).
1. An outer pipe of an outlet of a volute of a heat-transfer pump, arranged in a recess defined in a heat engine of a vehicle, the outer pipe being provided on an outer surface of a cylinder housing of the engine, and comprising:
a first component configured to guide the heat-transfer fluid from said outlet toward an inlet of an inner circuit for circulating the heat-transfer fluid defined in the cylinder housing; and
a second component forming, together with the first component, a first channel for circulating the heat-transfer fluid toward at least one device of a cooling circuit,
wherein the first component forms, together with the outer surface of the housing, a second channel for circulating the heat-transfer fluid toward said inlet of the inner circuit for circulating the heat-transfer fluid defined in the cylinder housing.
2. The outer pipe according to claim 1 , wherein:
the first component includes an area through which the heat-transfer fluid passes from the second channel to the first channel, and/or
an area through which the heat-transfer fluid passes from the second channel to the first channel includes at least one opening.
3. The outer pipe according to claim 1 , wherein the first component and the second component:
are two separate parts that are sealing connected together, and/or
together form a single part.
4. The outer pipe according to claim 1 , wherein the outer pipe is a removable part and/or an attachment.
5. A cylinder housing of an engine of a vehicle including a cooling circuit provided with a heat-transfer pump arranged in said cylinder housing and an outer pipe according to claim 1 .
6. The cylinder housing according to claim 5 , wherein:
the outer surface of said housing includes a cavity for mounting said outer pipe, and/or
the cylinder housing is manufactured according to a high-pressure casting foundry process, and/or
the cylinder housing is made from aluminum or an aluminum alloy, and/or
the mounting cavity forms a cavity provided with two ports corresponding to the outlet of the volute of the heat-transfer pump, and to the inlet of the inner circuit for circulating the heat-transfer fluid defined in the cylinder housing, respectively, and/or
the mounting cavity includes a connection area at which the outer pipe is mechanically and sealingly connected to the outer surface of the cylinder housing.
7. An engine including a cylinder housing according to claim 5 .
8. A vehicle including an engine according to claim 7 .
