[0039] Example

[0040] Reference Figure 1 and Figure 2 The utility model provides a chiller, comprising a chiller, wherein a first cover 150 is provided at a first end of the chiller, and a second cover 160 is provided at a second end of the chiller;

[0041] At least one air inlet is provided on the first cover 150, and at least one air outlet is provided on the second cover 160; the chiller has an installation cavity, and a dry cooler 300 and a condenser 400 are sequentially arranged side by side in the installation cavity along a first direction;

[0042] An air inlet cavity is formed between the first cover 150 and the dry cooler 300, an air flow cavity is formed between the dry cooler 300 and the condenser 400; and a fan cavity is formed between the condenser 400 and the second cover 160;

[0043] The first direction is a direction from the first cover body 150 to the second cover body 160 .

[0044] A condenser 400 and a dry cooler 300 are provided in the chiller. The condenser 400 utilizes a mechanical circuit for cooling, while the dry cooler 300 utilizes a natural cooling source from the environment for cooling. When the ambient temperature of the chiller is low, the airflow with a low ambient temperature is utilized to exchange heat with the dry cooler 300, thereby realizing air-cooled heat exchange and utilizing a natural cooling source from the environment for cooling.

[0045] After the chiller is assembled to the energy storage battery compartment, the air inlet and the air outlet are both connected to the outside, and the air flow can enter the installation cavity from the air inlet, and the air flow passes through the dry cooler 300 and the condenser 400 in sequence; wherein, a group of heat dissipation fans 200 can be used to cool the dry cooler 300 and the condenser 400 at the same time; when the ambient temperature of the dry cooler 300 is high, the dry cooler 300 does not work, and the heat dissipation fan 200 only dissipates heat for the condenser 400. When the dry cooler 300 and the condenser 400 are working at the same time, since the temperature of the coolant in the dry cooler 300 is much lower than the temperature of the refrigerant in the condenser 400, the cold air first passes through the dry cooler 300 and then passes through the condenser 400 for heat dissipation, so that the heat dissipation fan 200 can dissipate heat for the dry cooler 300 and the condenser 400 at the same time without affecting each other, thereby reducing the energy consumption of the unit.

[0046] An airflow cavity is formed between the condenser 400 and the dry cooler 300, so that the airflow can exchange heat independently between the dry cooler 300 and the condenser 400, and no heat radiation will be generated between them to affect the heat exchange effect. In addition, the formed airflow cavity can also comb the airflow after heat exchange from the dry cooler 300, reduce the turbulence of the airflow, and flow to the condenser 400 more evenly, thereby reducing the wind resistance of the condenser 400 and improving the heat exchange efficiency of the condenser 400.

[0047] Reference Figure 1 , in an optional embodiment, the dry cooler 300 and the condenser 400 are both V-shaped;

[0048] The V-shaped tips of the dry cooler 300 and the condenser 400 face the first cover 150 ; and the V-shaped openings of the dry cooler 300 and the condenser 400 face the second cover 160 .

[0049] The dry cooler 300 and the condenser 400 are both V-shaped; the air inlet areas of the dry cooler 300 and the condenser 400 can be increased, thereby improving the heat exchange efficiency.

[0050] In an optional embodiment, the dry cooler 300 and the condenser 400 have the same V-shaped setting angle and are stacked. Thus, since both are set to the same V-shape angle, when the two are stacked, the dry cooler 300 and the condenser 400 occupy very little space in the chiller. Thus, the heat exchange efficiency can be improved while reducing the size of the unit.

[0051] In addition, the distance between the dry cooler 300 and the condenser 400 is set to 6-15 mm. Preferably, the distance between the dry cooler 300 and the condenser 400 is 10 mm. The distance between the dry cooler 300 and the condenser 400 forms the airflow cavity. On the premise that the airflow cavity combs the airflow and the dry cooler 300 and the condenser 400 do not generate heat radiation to each other, the distance between the two is minimized, thereby optimizing the space occupied by the two in the chiller.

[0052] In an optional embodiment, a plate heat exchanger 110 is disposed in the air inlet cavity, and the plate heat exchanger 110 is disposed close to the tip of the dry cooler 300 .

[0053] Since the V heat exchanger is composed of two heat exchangers, the air intake at the tip of the V heat exchanger is the smallest and the heat exchange efficiency is the worst. Therefore, the higher plate heat exchanger 110 is placed at the tip of the dry cooler 300. The plate heat exchanger 110 has the smallest impact on the air intake of the dry cooler 300, thereby not affecting the heat exchange efficiency of the dry cooler 300.

[0054] Reference Figure 1 and Figure 2 (Hide the upper end cover), in an optional embodiment, a third cover body 170 and a fourth cover body 180 are respectively provided on both sides of the first direction of the chiller; the two ends of the first direction of the third cover body 170 and the fourth cover body 180 are respectively connected to the first cover body 150 and the second cover body 160;

[0055] The first cover body 150 , the second cover body 160 , the third cover body 170 and the fourth cover body 180 form a frame, an upper end cover is disposed at the upper end of the frame, and a lower bottom cover 210 is disposed at the lower end of the frame.

[0056] Generally, the plate heat exchanger 110, the refrigerant liquid pump 700, the compressor 500 and the electronic expansion valve 600 are all arranged on the lower bottom cover 210, and the first cover body 150, the second cover body 160, the third cover body 170 and the fourth cover body 180 are arranged along the circumference of the lower bottom cover 210; the upper end cover is arranged opposite to the lower bottom cover 210, generally so that the chiller forms a rectangular frame.

[0057] In an optional embodiment, an electric control component 120 is provided in the air inlet cavity;

[0058] The electric control component 120 is slidably disposed inside the third cover body 170 , and an assembly hole is disposed on the first cover body 150 , and one end of the electric control component 120 is clamped outside the first cover body 150 and connected to the first cover body 150 .

[0059] The electric control component 120 is generally fixed to the outside of the first cover body 150 with screws. When the electric control component 120 needs to be repaired, the electric control component 120 is pulled out from the assembly hole. This facilitates the repair of the electric control component 120 and improves the repair efficiency. Compared with the prior art, it is necessary to open the upper end cover, which reduces the difficulty of repair.

[0060] In addition, the electronic control component 120 is arranged on the inner side of the third cover body 170 and connected to the first cover body 150. In this way, the electronic control component 120 avoids the air flow path from the air inlet to the dry cooler 300 as much as possible, thereby avoiding blocking the air flow path and affecting the heat exchange efficiency of the dry cooler 300 and the condenser 400.

[0061] In an optional embodiment, a compressor 500, a refrigerant liquid pump 700, a heater 130 and an expansion tank 190 are also provided in the air inlet chamber; the compressor 500, the refrigerant liquid pump 700, the heater 130 and the expansion tank 190 are all installed horizontally, and the compressor 500 is arranged close to the third cover body 170, the heater 130 is arranged close to the fourth cover body 180, the refrigerant liquid pump 700 is arranged close to the plate heat exchanger 110, and the expansion tank 190 is arranged on the inner side of the fourth cover body 180 and close to the first cover body 150.

[0062] From the above arrangement, it can be seen that the main parts are arranged on both sides of the plate heat exchanger 110, avoiding wind blocking of the air flow path from the air inlet to the dry cooler 300 as much as possible, thereby improving the heat exchange efficiency.

[0063] Reference Figure 2 and Figure 3 In an optional embodiment, a coolant inlet 800 and a coolant supply port 900 are provided on the first cover body 150;

[0064] A first connecting pipeline 230 is provided between the plate heat exchanger 110 and the brine inlet 800; a second connecting pipeline 240 is provided between the brine supply port 900 and the plate heat exchanger 110;

[0065] The dry cooler 300 is connected to the first connecting pipeline 230 via a third connecting pipeline 250 , and the dry cooler 300 is connected to the second connecting pipeline 240 via a fourth connecting pipeline 260 ;

[0066] The heater 130 is disposed on the second connecting pipeline 240 ; and the electromagnetic two-way valve 220 is disposed on the third connecting pipeline 250 .

[0067] In an optional embodiment, one end of the condenser 400 is connected to one end of the plate heat exchanger 110 through a fifth connecting pipe 270, and the other end of the condenser 400 is connected to the other end of the plate heat exchanger 110 through a sixth connecting pipe 280;

[0068] A compressor 500 is disposed on the fifth connecting line 270 , and an electronic expansion valve 600 is disposed on the sixth connecting line 280 .

[0069] The refrigerant inlet 800 and the refrigerant supply port 900 of the chiller are both connected to the cold plate of the energy storage battery compartment. After the refrigerant enters the first connecting pipeline 230 from the refrigerant inlet 800, it enters the plate heat exchanger 110 after being pressurized by the refrigerant liquid pump 700. The temperature of the refrigerant is reduced after passing through the plate heat exchanger 110, and then it enters the cold plate of the energy storage battery compartment from the refrigerant supply port 900, thereby taking out the heat in the cold plate of the energy storage battery compartment and making the energy storage battery compartment have a suitable working temperature.

[0070] A liquid replenishing port is also provided on the first cover body 150 , and the liquid replenishing port is used to replenish the coolant. Exemplarily, the liquid replenishing port is connected to the first connecting pipeline 230 .

[0071] When the ambient temperature is low, the electromagnetic two-way valve 220 is in an open state, and the coolant can still enter the dry cooler 300 , and the dry cooler 300 is used to cool the coolant.

[0072] The refrigerant in the first connecting pipeline 230 enters the third connecting pipeline 250, and then enters the dry cooler 300; the refrigerant undergoes heat exchange at the dry cooler 300 to reduce the temperature of the refrigerant, and the cooled refrigerant enters the fourth connecting pipeline 260, and then enters the second connecting pipeline 240 along the fourth connecting pipeline 260, thereby achieving cooling of the energy storage battery compartment.

[0073] When the ambient temperature is high, the electromagnetic two-way valve 220 is in a closed state, and the coolant enters the plate heat exchanger 110. The plate heat exchanger 110 exchanges heat with the coolant to cool the coolant.

[0074] The plate heat exchanger 110 is connected to the condenser 400 through the fifth connecting pipe 270 and the sixth connecting pipe 280; after the refrigerant exchanges heat with the coolant at the plate heat exchanger 110, the refrigerant absorbs the heat of the coolant at the plate heat exchanger 110, and the refrigerant evaporates into a low-temperature and low-pressure gaseous refrigerant, and then the refrigerant enters the compressor 500 and is compressed into a high-temperature and high-pressure superheated gas; the superheated refrigerant vapor enters the condenser 400 and condenses into a high-temperature and high-pressure supercooled liquid; then the refrigerant enters the electronic expansion valve 600 for throttling and pressure reduction, and after throttling, the refrigerant is in a low-temperature and low-pressure gas-liquid two-phase state; after absorbing heat in the plate heat exchanger 110, it evaporates again into a low-temperature and low-pressure gas and enters the compressor 500. In this way, the refrigeration cycle is continuously performed.

[0075] When the compressor 500 is not started, the plate heat exchanger 110 cannot cool the refrigerant, that is, when the outside temperature is low enough and the refrigerant can meet the cooling demand of the energy storage battery compartment through the dry cooler 300, the compressor 500 is not started and natural cooling is achieved; when the energy storage battery compartment cannot be cooled by the dry cooler 300 alone, the compressor 500 is started, and natural cooling and mechanical cooling are combined to cool the energy storage battery compartment.

[0076] When the external environment is high, the electromagnetic two-way valve 220 is in a closed state, and all the refrigerant enters the plate heat exchanger 110. The condenser 400 is used to cool the refrigerant in the plate heat exchanger 110, that is, mechanical refrigeration.

[0077] When the ambient temperature is too low, the heater 130 may be used to heat the pipeline during startup to prevent the pipeline from freezing and becoming unusable.

[0078] In an optional embodiment, one end of the condenser 400 is connected to one end of the plate heat exchanger 110 through a fifth connecting pipe 270, and the other end of the condenser 400 is connected to the other end of the plate heat exchanger 110 through a sixth connecting pipe 280;

[0079] A compressor 500 is disposed on the fifth connecting line 270 , and an electronic expansion valve 600 is disposed on the sixth connecting line 280 .

[0080] In an optional embodiment, a filter screen 140 is provided at the air inlet;

[0081] A fan mounting plate 100 is disposed in the fan cavity, and at least one heat dissipation fan 200 is disposed on the fan mounting plate 100; and each of the heat dissipation fans 200 corresponds to one of the air outlets.

[0082] In some embodiments, a filter 140 is provided at the air inlet, and the air enters the air inlet chamber after being filtered by the filter 140, which can prevent larger foreign objects from entering the chiller and avoid affecting the heat exchange efficiency.

[0083] A heat dissipation fan 200 is arranged on the fan mounting plate 100. For example, two heat dissipation fans 200 are arranged on the fan mounting plate 100, and two air outlets are arranged on the second cover body 160. Each heat dissipation fan 200 corresponds to an air outlet, and an air guide ring is arranged on the heat dissipation fan 200. The air guide ring is conducive to introducing the air in the fan cavity into the heat dissipation fan 200, so that the air in the fan cavity is quickly discharged from the air outlet, thereby accelerating the air flow in the chiller; and the two heat dissipation fans 200 are symmetrically distributed, and the air flow curve of the heat dissipation fan 200 is reasonably utilized to increase the air volume while reducing the power consumption of the heat dissipation fan 200.

[0084] The coolant can be water or ethylene glycol solution, etc., and the refrigerant can be Freon, etc.; the coolant and the refrigerant are both existing technologies.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
