Description

Heat exchanger

The present invention relates to a heat dissipating device, and more particularly to a heat exchanger.

Conventional liquid-cooled heat exchangers direct the coolant to the heat-dissipating portion or carry the heat source away through the heat-dissipating fins. Therefore, the way of heat dissipation is achieved by the fluid flowing in a predetermined flow path to absorb heat energy. However, as the future products are gradually introduced into miniaturization, resulting in high density, high power and high heat generation of parts, the conventional predetermined coolant flow path design is becoming increasingly difficult.

The existing coolant flow channel design is roughly divided into two types, one is a circular pipe deflection layout, and the other is a body flow hole hole design.

The deflection mode of the round pipe is relatively common at present (for example, TW certificate number No. I437417), and the round pipe is mainly disposed close to the heat dissipation portion or the heat dissipation fin, and the cooling liquid in the pipe can achieve the purpose of heat dissipation. However, the winding of the round tube involves the difficulty of bending on the processing and the strength of the corner of the turning R. However, as mentioned above, the introduction of the product into the miniaturization will make the processing more difficult, and the too small tube bend will be at the turning point. Insufficient strength, or difficulty in assembling the product at the corner of the turn, and the smaller the product, the greater the difficulty and cost of arranging the heat exchanger through the flexible tube.

As for the design of the body flow hole (for example, TW Certificate No. M556996), it is also difficult to process when it is necessary to lay the flexible flow path, and the smaller the size of the same product, the greater the difficulty and cost. .

Accordingly, it is an object of the present invention to provide a heat exchanger which is easy to manufacture and which can solve the problem of insufficient strength of a bent portion.

Therefore, the novel heat exchanger comprises a heat dissipating fin, at least one tube unit and at least two joints. The heat dissipating fin member includes at least one connecting surface, the tube tube unit includes a first plate member that is in contact with the connecting surface, and a second plate member that is fixed to the first plate member, the first plate member has a first plate member a first bonding surface, the second plate member has a second bonding surface that is in contact with the first bonding surface, and at least one of the first bonding surface and the second bonding surface is recessed a groove defining a first-class track, the flow prop having a lead-in end, and a discharge end opposite to the lead-in end in a flow direction, the joints being respectively connected to opposite ends of the plate tube unit and respectively connected At the introduction end of the flow channel and the discharge end.

The utility model has the advantages that the first tube member and the second plate member are provided by the tube tube unit, and the first plate member and the second plate member can be made by using a sheet metal piece and punched, not only manufacturing and processing It is easy and can solve the problem of insufficient strength of the bending portion of the existing bending control process.
