Abstract

A manifold includes: a manifold body including a high-temperature portion including a high-temperature channel through which a high-temperature fluid having a temperature equal to or higher than a first temperature flows, and a low-temperature portion including a low-temperature channel through which a low-temperature fluid having a temperature equal to or lower than a second temperature that is lower than the first temperature flows; and an anchoring portion that anchors the manifold body to an anchorage object. The anchoring portion is at least one anchoring portion disposed at an end of the low-temperature portion of the manifold body.

Description

TECHNICAL FIELD The present disclosure relates to a manifold. BACKGROUND ART Hitherto, there is known a system that is related to thermal management and is installed in a vehicle for the purpose of air conditioning of a vehicle cabin, etc. (e.g., Patent Document 1). Patent Document 1 discloses a manifold (thermal management system in Patent Document 1) that includes a coolant reservoir, channels, a mounting portion, and a mounting bracket, and through which fluids (coolant and refrigerant) flow. The mounting portion is equipped with a plurality of water pumps, a plurality of valves, a plurality of heat exchangers, etc. The mounting bracket includes four anchoring portions (mounting feet in Patent Document 1), and the manifold is fixed to a vehicle body by fixing the anchoring portions to a vehicle body support frame. Related Art Documents Patent Documents Patent Document 1: Chinese Unexamined Patent Application Publication No. 114789636 (CN 114789636 A) SUMMARY OF THE INVENTION Problem to be Solved by the Invention Since the manifold disclosed in Patent Document 1 includes the plurality of heat exchangers, a high-temperature fluid and a low-temperature fluid flow through the manifold. That is, the manifold includes a high-temperature circuit through which the high-temperature fluid flows and a low-temperature circuit through which the low-temperature fluid flows. In general, substances contract at low temperatures and expand at high temperatures. In the manifold, a portion including the high-temperature circuit expands and a portion including the low-temperature circuit contracts. For example, when two or more of the four anchoring portions are formed at the portion including the low-temperature circuit, the anchoring portions are fixed and anchored to the vehicle body support frame, and the areas near the two or more anchoring portions formed at the portion including the low-temperature circuit contract to generate tensile stress between the two or more anchoring portions. In the worst case, the manifold may be damaged. Therefore, there is a demand for a manifold that is resistant to damage even when fixed and anchored to a vehicle body support frame etc. Means for Solving the Problem A manifold according to one embodiment of the present disclosure includes: a manifold body including a high-temperature portion including a high-temperature channel through which a high-temperature fluid having a temperature equal to or higher than a first temperature flows, and a low-temperature portion including a low-temperature channel through which a low-temperature fluid having a temperature equal to or lower than a second temperature that is lower than the first temperature flows; and an anchoring portion that anchors the manifold body to an anchorage object. The anchoring portion is at least one anchoring portion disposed at an end of the low-temperature portion of the manifold body. In the present embodiment, the at least one anchoring portion is disposed at the end of the low-temperature portion of the manifold body. Therefore, the manifold is less likely to be damaged. Since the anchoring portion is disposed at the end of the low-temperature portion of the manifold body, the anchoring portion does not hinder the disposition of the high-temperature channel or the low-temperature channel.
