The present specification does not limit the medium to be cooled of the apparatus to be cooled 200, and for example, the medium to be cooled may be a gas or a liquid. In the present embodiment, the medium to be cooled of the heat sink 100 is gas, and the heat sink 100 is used to provide a gas cooling scheme for the compressor of the refrigeration equipment 200.

The present application is not limited to a particular type of refrigeration appliance 200, for example, the refrigeration appliance 200 may be a refrigerated display case, a beverage cooler, or the like. The refrigerating apparatus 200 may include a compressor 201, an evaporator 203, and a heat sink 100. The compressor 201 is provided with a discharge pipe 2012, and the discharge pipe 2012 is connected to the heat sink 100. The evaporator 203 has a defrosting water outlet 2032, and the defrosting water outlet 2032 is connected to the heat sink 100 and is used for draining defrosting water into the heat sink 100.

When the refrigeration apparatus 200 works, the gas is compressed by the compressor 201 to become a high-temperature high-pressure gas, a large amount of heat is generated, the high-temperature high-pressure gas enters the heat dissipation device 100 through the discharge pipe 2012, and the heat dissipation device 100 cools and releases the high-temperature high-pressure gas to throttle the gas which becomes a medium-temperature medium-pressure gas or a low-temperature low-pressure gas. The defrosting water of the evaporator 203 enters the heat dissipation device 100 through the defrosting water outlet 2032, which promotes the heat dissipation of the heat dissipation device 100 on the one hand and accelerates the evaporation of the defrosting water on the other hand.

The heat exchanger 50 is disposed in the loading chamber 21 and is connected in series between the cooling pipe 40 and the output pipe 60, and the output pipe 60 is used for discharging cooled gas.

When the refrigerating apparatus 200 works, the high-temperature gas (to-be-cooled medium) compressed by the compressor 201 enters the cooling pipe 40 through the discharge pipe 2012 and the input pipe 30, and the gas performs primary heat exchange with the cooling water in the loading cavity 21 in the cooling pipe 40. The gas enters the heat exchanger 50 through the cooling pipe 40, the heat exchanger 50 carries out secondary heat dissipation on the gas, and the gas after temperature reduction is changed into medium-temperature medium-pressure gas or low-temperature and low-pressure gas which is discharged through the output pipe 60. Therefore, the heat dissipation device 100 can perform primary and secondary heat dissipation on the medium to be cooled, thereby greatly improving the heat exchange efficiency.

In the present embodiment, the installation case 10 has a substantially hollow box shape, and both the compressor 201 and the evaporator 203 can be connected to the outer peripheral wall of the installation case 10. In a typical use condition, the installation box 10 is placed on a horizontal surface (e.g., a ground surface or other installation platform), and one side of the installation box 10, which is attached/overlapped on the horizontal surface, is a bottom of the installation box 10, and the side opposite to the bottom is a top of the installation box 10.

In the present embodiment, the loading box 20 is provided at the bottom of the installation case 10, which is used for installing the cooling pipe 40 and the heat exchanger 50.

The loading box 20 has a first end 23 and a second end 24 opposite to each other, and the direction from the first end 23 to the second end 24 is a second direction Y, which intersects (e.g. is perpendicular to) the first direction X, and in this embodiment, the second direction Y is the width direction of the loading box 20.

The cooling water in the loading cavity 21 may be additional cooling water, or defrosting water in the refrigeration apparatus 200 may be used as the cooling water. In the present embodiment, the cooling water in the loading chamber 21 is introduced into the defrosting water in the evaporator 203. In order to introduce the defrosted water in the evaporator 203 into the loading chamber 21 to become the cooling water, in this embodiment, the heat dissipating device 100 further includes a first water inlet pipe 70. The first water inlet pipe 70 is connected between the installation case 10 and the evaporator 203, and is used for cooling water of the evaporator 203 to flow through to enter the loading chamber 21 through the first water inlet pipe 70.

The gas in the cooling pipe 40 exchanges heat with the cooling water to perform primary heat dissipation.

The gas in the cooling tube 40 enters the heat exchanging coil 54 through the input port 51 and flows along the heat exchanging coil 54, and in the process, the heat dissipating fins 534 absorb the heat of the medium to be cooled, perform secondary heat dissipation, and dissipate the heat in a convection manner. The condensed water of the refrigeration equipment 200 is dripped on the heat dissipation fins 534 and the heat exchange coil 54 through the second water inlet pipe 80, and the condensed water directly exchanges heat with the heat dissipation fins 534 and the heat exchange coil 54, so that the purpose of reducing the temperature of the medium to be cooled is achieved, and the secondary heat dissipation efficiency is improved. The condensed water falls into the containing cavity 21 and then is used as cooling water in the containing cavity 21, and primary heat dissipation is promoted.

The direct-current air of the heat exchange fan 110 performs forced convection heat exchange on the heat exchanger 50, and simultaneously takes away partial heat of the falling condensed water, so as to perform three-stage heat dissipation, thereby further improving the heat dissipation efficiency. The air outlet of the heat exchange fan 110 takes away part of heat of cooling water in the loading cavity 21, and primary heat dissipation is promoted.

The heat dissipation device 100 performs first-level, second-level and third-level heat dissipation on a to-be-cooled medium, and the first-level, second-level and third-level heat dissipation have mutual influence and are linked with each other, so that the gas temperature can be effectively reduced, and the capability of evaporating defrosting water and condensed water can be improved.
