Description

Technical Field The present disclosure relates to the field of heat exchange apparatus technologies, and particularly to an outer housing, a core body, and an intercooler. Background Art Generally, an intercooler includes a core body, a chamber body, and a main plate, the main plate is sleeved over the core body, and the chamber body is mounted on the core body by the main plate, such that the chamber body is communicated with the core body to form a sealed environment, and gas may flow into the core body from one side of the chamber body for heat exchange and flow out from the other side of the chamber body. Generally, the core body includes a plurality of chips stacked together, and in order to prevent the plural chips from loose movement after the chips are connected, the outer housing is sleeved over the whole formed after the chips are connected; the outer housing is generally formed by abutting two U-shaped housings with the same size, and abutting positions of the two U-shaped housings are welded to form a welding seam extending in the gas flow direction, such that gas is limited inside the chamber body and the housings. The inventors found in researches that the existing intercooler has the following disadvantages: after the two U-shaped housings are welded, gas leakage is easy to occur at the welding seam. Prior art documents WO 2011/064090, KR 2016 0100599 and CN 104976818 disclose a housing where a gas blocking portion extends through a seam therein. Summary An object of the present disclosure is to, for example, provide an outer housing, a core body, and an intercooler, which may improve the problem that gas leakage is easy to occur at a welding seam of two housings of an existing intercooler. An embodiment of the present disclosure is implemented as follows. One aspect of the present disclosure provides an outer housing, a seam extending in the first direction is formed on the outer housing, and at least one gas blocking portion penetrating through the seam is formed at the seam. The outer housing includes a first housing and a second housing abutting each other to form the seam, and the first housing, the seam, and the second housing are arranged in sequence in the second direction; the gas blocking portion extends in the second direction, or the extension direction of the gas blocking portion is inclined relative to the second direction; the first direction and the second direction have an included angle. The technical solution has the following beneficial effects: on the outer housing, the seam formed by abutting the first housing and the second housing is a long seam on the outer housing, and has a relatively large leakage risk, and the gas blocking portion is provided at the seam formed by abutting the first housing and the second housing, so as to better play its gas blocking effect, thus achieving a more obvious gas leakage alleviation effect. Optionally, the number of the gas blocking portions is at least two, and the at least two gas blocking portions are arranged in the first direction. The technical solution has the following beneficial effects: when gas leaks from the seam, no matter in the first direction or the direction perpendicular to the first direction, the gas blocking portions may effectively block leaked airflow, and the at least two gas blocking portions have a better airflow blocking effect. Each gas blocking portion has a sheet-shaped, plate-shaped or block-shaped convex structure. The gas blocking portion and the first housing are integrally formed. The technical solution has the following beneficial effects: integral formation of the gas blocking portion and the first housing may avoid a connecting trace at the position where the gas blocking portion is connected with the first housing, and thus avoids the possibility that the gas leaks from the connecting trace; due to the integral formation, the portion of the gas blocking portion formed at the first housing has higher strength, thus reducing the risk that the portion of the gas blocking portion is broken possibly at the formation position; and moreover, the integral formation avoids the step of assembling the gas blocking portion, thus simplifying the production process, and improving the production efficiency. Optionally, a groove portion cooperating with the gas blocking portion to accommodate the gas blocking portion is formed on the second housing. The technical solution has the following beneficial effects: when the first housing abuts the second housing, the gas blocking portion is located in the groove portion, such that the gas blocking portion may be prevented from hindering the abutment between the first housing and the second housing, and then, two edges of the seam formed between the first housing and the second housing may be attached tightly, thus reducing a gas leakage risk. Optionally, the two side edges of the gas blocking portion in the first direction are attached to the inner wall of the groove
