Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly described below with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the utility model, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the utility model.

In the description of the present invention, unless otherwise specified, the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplified description, and do not indicate or imply that the system or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

It is to be understood that, unless otherwise expressly stated or limited, the term "coupled" is used in a generic sense as defined herein, e.g., fixedly attached or removably attached or integrally attached; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the utility model can be understood in specific cases to those of ordinary skill in the art.

As shown in fig. 1 and 2, an embodiment of the present invention provides a mobile phone case, which includes a mobile phone case body 1, a cavity 2 is provided in the mobile phone case body 1, and a low melting point alloy is filled in the cavity 2.

When the mobile phone shell is used, the heat generated by the mobile phone in the operation process can be rapidly transmitted to the outside by utilizing the good heat conductivity of the low-melting-point alloy, so that the speed and the performance of the mobile phone in the operation process can be ensured, the service life of the mobile phone can be prolonged, and the hardware of the mobile phone is prevented from being damaged due to untimely heat dissipation.

It should be noted that, because different brands of mobile phones may have different heat dissipation effects and heat dissipation positions, the size of the cavity 2 and the type of the low melting point alloy in the mobile phone case may be designed for different brands of mobile phones. Specifically, the method comprises the following steps: for a mobile phone with a short heat pipe and a central heating area, the cavity 2 is preferably disposed at a corresponding position in the center of the mobile phone housing 1. For example, as shown in fig. 3, when the heat generating region of the mobile phone is located at a position one third away from the top, a cavity 2 with a length, width and height of 50mm × 40mm × 3mm may be opened at a position one third away from the top of the mobile phone shell body 1. The low melting point alloy filled in the cavity 2 can be bismuth indium tin alloy with a melting point of 79 ℃, for example, bismuth indium tin alloy consisting of 50 wt% bismuth, 30 wt% indium and 20 wt% tin.

For a mobile phone with a long heat pipe and a heating region deviating from the center, the cavity 2 is preferably disposed on a side of the mobile phone shell 1 deviating from the center. For example, as shown in fig. 4, when the heat generating region of the mobile phone is located at a position to the left of the top, a cavity 2 with a length, width and height of 50mm × 20mm × 3mm may be formed at the left of the top of the mobile phone shell body 1. The low melting point alloy filled in the cavity 2 can be bismuth-indium alloy with a melting point of 100 ℃, for example, bismuth-indium alloy consisting of 70 wt% bismuth and 30 wt% indium.

Preferably, cell-phone shell body 1 includes shell body 4 and interior casing 3, has seted up first recess on the inner wall of shell body 4, and the second recess has been seted up to interior casing 3's outer wall, and interior casing 3's outer wall laminates with the inner wall of shell body 4 so that first recess encloses with the second recess jointly and establishes vacuole formation 2. More preferably, the outer shell 4 and the inner shell 3 are connected by gluing. The materials of the outer shell 4 and the inner shell 3 may be the same or different. For example, the material of the outer housing 4 and/or the inner housing 3 may be, but is not limited to, leather, silicone, cloth, hard plastic, soft plastic, or rubber.

Preferably, the longitudinal cross-sectional shape of the cavity 2 is polygonal, circular or elliptical.
